Specs and Trims Overview

BYD’s sleek Seal brings Chinese EV tech and sharp styling to challenge the Model 3 and Ioniq 6.

Before diving deeper, let’s look at how the Model 3, BYD Seal, and Ioniq 6 stack up on paper. All three are five-seat, four-door electric sedans with similar footprints, but there are key differences in their powertrains and trim line-ups:

• Tesla Model 3 – Available in Rear-Wheel Drive (RWD) Standard Range (LFP battery), Long Range (in some regions offered as RWD or Dual-Motor All-Wheel Drive), and Performance AWD trims. The 2024 refresh (codename “Highland”) brought a sleeker design, upgraded interior, and efficiency tweaks carwow.co.uk carmagazine.co.uk. Tesla’s base RWD has ~60 kWh battery and ~318 miles (513 km) WLTP range, while the Long Range can go up to ~390–436 miles WLTP (~627–701 km, depending on single/dual motor) carmagazine.co.uk independent.co.uk. The Performance version sacrifices some range for blistering 0–60 mph in ~3 seconds independent.co.uk independent.co.uk.
• BYD Seal – Launched 2022 in China (landing in Europe/Australia in 2023–24), the Seal targets the Model 3 directly on size, specs, and price carmagazine.co.uk carmagazine.co.uk. Most markets get two trims: a single-motor Design (RWD) and a dual-motor Excellence AWD – both using BYD’s large 82.5 kWh “Blade” LFP battery independent.co.uk. (In China/Aus a smaller 61.4 kWh RWD variant is also offered as the entry Dynamic trim thedriven.io.) The RWD Seal makes ~308 hp and the AWD a whopping ~523 hp carmagazine.co.uk. Claimed range is up to ~570 km (354 mi) WLTP for the RWD and ~520 km (323 mi) for AWD thedriven.io. Despite ~390 kW (523 hp) on tap in the Performance AWD (0–100 km/h in 3.8 s byd.com), BYD actually prices the Seal lower than an equivalent Model 3 in many markets carwow.co.uk – but is it too good to be true? We’ll see what reviewers found.
• Hyundai Ioniq 6 – The Ioniq 6 launched in 2023 as an “electrified streamliner” sedan, and immediately swept World Car of the Year 2023 awards (World Car of the Year, World EV, and World Car Design) hyundai.news. It offers Standard Range (53 kWh battery, 149 hp RWD) and Long Range (77.4 kWh, 225 hp RWD or 320 hp Dual-Motor AWD) models edmunds.com. In the U.S. you’ll see SE/SEL/Limited trims, while some countries use names like Dynamiq and Epiq. The longest-range Ioniq 6 is the 77.4 kWh RWD on 18″ wheels, rated 614 km WLTP (382 miles) – one of the best in the industry southernteamhyundai.com southernteamhyundai.com. Opting for AWD or larger 20″ wheels reduces that (e.g. AWD on 20″: ~519 km WLTP) southernteamhyundai.com, but even the base 53 kWh version gets a respectable ~429 km WLTP (267 mi) southernteamhyundai.com. Every Ioniq 6 supports ultra-fast 800V charging, meaning a 10–80% top-up in as little as 18 minutes under ideal conditions edmunds.com.

Price: All three of these EVs start around the $40,000 (£40k) mark for their base trims, with well-equipped higher models stretching into the $50k+ range. Tesla recently cut prices to keep the Model 3 competitive – e.g. in the UK the RWD starts at £39,990 independent.co.uk, undercutting the BYD Seal (from ~£45,000) independent.co.uk. Hyundai’s Ioniq 6 starts around $39k in the US for the Standard Range SE and about £47k in the UK for a Long Range model. We’ll dig more into value and equipment in the Pricing & Value section, but first, let’s compare how these EV sedans perform on the road.

Key Specifications Comparison: Tesla vs BYD vs Hyundai at a glance:

<small>^＊800 V architecture allows up to 350 kW charging, but Ioniq 6 is limited by 233 kW max in practice edmunds.com.</small>

As the table shows, each car has its own strengths: Tesla is lighter and most efficient, with the longest real-world rangeand access to the extensive Supercharger network. BYD offers the largest battery and highest horsepower in AWD form, packing a ton of features for the price. Hyundai boasts the fastest charging and a head-turning design with top-notch safety credentials (it even earned an IIHS Top Safety Pick+ in the US) hyundai.com hyundai.com. Now, let’s break down how these differences play out in each category.

Performance and Driving Experience

Acceleration & Power: If you’re after neck-snapping acceleration, Tesla’s Model 3 Performance is the undisputed champ – launching 0–60 mph in about 3.0 seconds in its latest iteration independent.co.uk independent.co.uk. The BYD Seal AWD is no slouch, though: its “3.8S” badge (proudly displayed on the rear of the car) advertises its 3.8 sec 0–100 km/h sprint independent.co.uk, roughly 0–60 mph in 3.6 sec – quicker than a Model 3 Long Range AWD (4.2 s 0–60) independent.co.uk. The base single-motor models are tamer: BYD claims 5.9 s 0–62 for the Seal RWD independent.co.uk, just a hair slower than the 5.8 s Tesla Model 3 RWD clocked by independent tests independent.co.uk. Hyundai’s Ioniq 6, especially the Long Range AWD (~5.1 s 0–100 km/h), is brisk but not as outright fast – it focuses more on efficiency and comfort than drag-race stats whichcar.com.au. The Standard Range Ioniq 6 (149 hp) is the slowpoke of the bunch, around 8.5–9 sec 0–60, adequate for daily driving but far from thrilling.

Driving Dynamics: Tesla has a reputation for making EVs fun, and the Model 3 still delivers a go-kart-like feel with sharp steering and instant throttle response. Reviewers consistently praise the Model 3’s sporty handling: “it grips well… you can really have a laugh with it on a country road,” writes Carwow carwow.co.uk. The updated 2024 Model 3also got retuned suspension, giving it a smoother ride without losing agility independent.co.uk independent.co.uk. By comparison, the BYD Seal is tuned a bit softer. It’s described as comfortable over bumps but “feels more vague and less composed… not quite as precise and tied-down as the Tesla” carwow.co.uk. Pushing the Seal hard will still put a smile on your face – testers note you can get the RWD Seal’s tail to kick out playfully – but overall it’s tuned for stable, easy everyday driving rather than track attacks carwow.co.uk.

Hyundai’s Ioniq 6 falls somewhere in between. It’s not aimed to be overtly sporty, but its low center of gravity and long wheelbase give it a confident, planted feel on highways. With its focus on aerodynamics and comfort, the Ioniq 6 is a quiet cruiser – more about smoothing out the ride than carving corners. That said, the AWD version’s dual motors (239 kW combined) provide strong all-weather grip and quick acceleration when needed whichcar.com.au. One neat trick: the Hyundai lets drivers dial in strong regenerative braking for one-pedal driving, and reviewers note the tuning is excellent – “right up there with Tesla’s” in calibration whichcar.com.au.

Braking & Handling: All three come with large disc brakes and adjustable regen. The Model 3’s lighter weight (~1,836 kg for the RWD vs ~2,100 kg for the others) whichcar.com.au is a key advantage – less mass means less inertia in corners and shorter stopping distances. The BYD Seal is the heaviest (its big battery and structural cell-to-body frame push it to ~2,185 kg) whichcar.com.au, and some of that shows in spirited driving: journalists observed the Seal AWD can feel a bit unsettled when braking hard into corners, with weight transfer making it nosedive more than the others whichcar.com.au. Hyundai’s Ioniq 6, despite its size, manages its weight well and strikes a balance between sporty and soft – but it’s clearly optimized for long-distance stability over aggressive handling. All three offer multiple drive modes to tweak throttle and steering response (Tesla even has a Track Mode on Performance). In short: driving enthusiasts will likely prefer the Tesla’s razor-sharp feel, commuters may appreciate the BYD’s comfort, and the Hyundai shines as an effortless long-haul cruiser.

Battery Range and Charging

Range anxiety? Not a huge worry with these three – each comfortably exceeds 300 miles (480 km) in its most efficient configuration. But Tesla’s relentless focus on efficiency gives the Model 3 Long Range a notable edge in real-world range. Even though its battery (~75 kWh) is smaller than the BYD’s, the Model 3 LR RWD (a variant available in Europe) is officially rated 436 miles (701 km) WLTP independent.co.uk. The dual-motor Long Range AWD is a bit lower (~370–390 miles WLTP, or ~334 miles EPA), but Tesla tends to outperform its ratings in many tests carmagazine.co.uk. The Model 3’s superb efficiency (~5 miles per kWh in ideal conditions) means it often matches or beats the Seal’s range despite a smaller battery whichcar.com.au. In fact, Tesla’s entry RWD (57.5 kWh LFP) gets 513 km WLTP whichcar.com.au, nearly on par with BYD’s 82.5 kWh AWD (520 km) whichcar.com.au – a testament to Tesla’s powertrain prowess.

The BYD Seal uses a big Blade LFP battery (82 kWh) known for durability and safety. Its official ranges are 570 km WLTP for the RWD and 520 km for AWD thedriven.io. Those are excellent, though some reports suggest the Seal’s realhighway range at 120 km/h might trail the Model 3 by ~10% due to less optimized aerodynamics and higher weight. Still, in normal mixed driving, the Seal should comfortably do 300+ miles on a charge. One advantage in daily use: LFP chemistry (in Tesla’s base and BYD’s packs) allows regular charging to 100% without long-term battery harm, whereas NCM batteries (Hyundai and Tesla LR) are usually charged to 80–90% daily to prolong life.

Hyundai’s Ioniq 6 Long Range RWD is the range king on paper: up to 614 km WLTP (382 mi) with 18″ wheels southernteamhyundai.com, thanks to its ultra-slippery 0.21 drag coefficient and efficient motors. U.S. EPA ratings convert to ~340 mi for the SE RWD (which still tops Tesla’s RWD EPA 272 mi rating). However, once you add AWD or bigger rims, the gap closes – e.g. an Ioniq 6 AWD on 20″ is rated ~519 km WLTP southernteamhyundai.com (~270 mi EPA). In practice, all three sedans can achieve around 250–300 miles (400–480 km) on a highway trip with the larger battery options, while the Standard Range Ioniq6 (53 kWh) is more like ~240 miles EPA. It’s worth noting the Ioniq 6 was engineered for efficiency: it won awards for energy use, consuming as low as 13.9 kWh/100 km in WLTP tests hyundai.news southernteamhyundai.com, making it one of the most efficient EVs alongside the Model 3.

Charging Speed: Here the Hyundai Ioniq 6 clearly shines – thanks to its 800-volt E-GMP platform, it can charge from 10% to 80% in just 18 minutes under ideal conditions edmunds.com. It supports up to 233 kW DC (and briefly peaks higher, ~250+ kW) on ultra-fast chargers edmunds.com. This means about 100 km of range in 5 minutes if you find a capable charger. Tesla’s Model 3 isn’t far behind: it maxes at 170 kW (older packs) to 250 kW (new pack) on V3 Superchargers, adding ~172 miles (277 km) in 15 minutes according to Tesla independent.co.uk. In our experience, the Model 3 LR can do 10–80% in ~25 minutes whichcar.com.au, and the network of Superchargers (20,000+ stalls globally) ensures easy road-trip charging – a huge Tesla advantage carwow.co.uk.

The BYD Seal’s charging is decent but not groundbreaking: it tops out at 150 kW DC (if you have the 82 kWh battery; the smaller 61 kWh pack is ~110 kW) aeva.asn.au. BYD claims 10–80% in ~37 minutes for the big battery whichcar.com.au. That’s a bit slower than the others, but still ~charge from 30% to 80% in 26 min as per BYD’s own site byd.com. One quirk: in our testing, the Seal’s charge curve was more tapered – it doesn’t hold peak power as long as the Tesla or Hyundai. Still, unless you constantly drive long distances, a 150 kW peak is fine – it’s comparable to many other mid-range EVs and will add ~200 km range in 20 minutes.

All three support 11 kW Level 2 AC charging (Teslas in North America do ~11.5 kW). On a home wallbox, the Tesla and Hyundai refill overnight (~7–8 hours for a full charge) whichcar.com.au. Oddly, the BYD Seal in some markets ships with only a 7 kW onboard charger whichcar.com.au, meaning it takes ~12 hours to fully charge on AC – a cost-cutting move from BYD, but something to consider if you rely on faster home charging.

Real-World and Extras: In real-world efficiency, Tesla likely has the edge at highway speeds (owners often report 4.5–5 mi/kWh in mixed driving independent.co.uk independent.co.uk). The Ioniq 6 isn’t far behind (its owners report ~4 mi/kWh is achievable) and actually beats Tesla in city efficiency. The Seal’s real consumption seems ~10% higher – partly due to its heavier LFP battery and perhaps less refined motor/inverter tuning. However, the Seal’s Blade Batteryhas other perks: BYD says it can last 5,000+ charge cycles (far more than a typical battery) byd.com byd.com, and it passed brutal safety tests (like nail penetration) without thermal runaway byd.com. All three cars offer battery preconditioning (Tesla’s is automatic when navigating to a Supercharger; Hyundai’s can be manual or based on nav; BYD’s app allows some control) to optimize charging speeds in cold weather.

One more neat feature: the Ioniq 6 includes Vehicle-to-Load (V2L) capability – it can power appliances or charge another EV at up to 3.6 kW using an adapter. Tesla and BYD don’t (currently) have V2L on these models. Hyundai also gives the Ioniq 6 a standard heat pump for cabin heating efficiency edmunds.com, whereas Tesla includes a heat pump from 2021-on. BYD Seal’s climate system – not confirmed if heat pump is standard, but likely in some markets it is, given its focus on tech.

Interior, Technology and Features

The Hyundai Ioniq 6’s futuristic cabin features dual 12.3″ screens and available augmented-reality HUD, emphasizing comfort and tech.

Design & Quality: These three interiors each have a distinct character. Tesla’s Model 3 cabin is famously minimalist – no instrument cluster, almost no physical buttons or stalks (as of the 2024 update, even the turn signals are buttons on the steering yoke) carwow.co.uk carwow.co.uk. This clean design feels airy and modern, but can frustrate those who prefer traditional controls carwow.co.uk. On the plus side, the 2024 refresh brought nicer materials (real aluminum trim, soft-touch surfaces) and added features like wraparound ambient LED lighting and ventilated seats carwow.co.uk. Tesla’s build quality has also improved – one reviewer noted the new Model 3 feels “better made… with greater refinement than the first generation” independent.co.uk. Still, some cost-cutting shows (no rear wiper on the sloped glass, etc.), and panel fit can be hit-or-miss.

The BYD Seal’s interior is more conventional in layout than Tesla’s, yet visually striking. It has a fully digital instrument display plus a large 15.6″ center touchscreen that uniquely can rotate between landscape and portrait orientation whichcar.com.au whichcar.com.au. (It’s a cool party trick, though some find it gimmicky.) BYD provides normal stalks for wipers/indicators and a physical gear selector – a relief for those who dislike Tesla’s screen-based shifter carwow.co.uk carwow.co.uk. Material quality in the Seal is quite impressive for a newcomer – soft leatherette, blue suede-like dash accents, and even standard heated and power-adjustable seats. Reviewers found it “a match for the Tesla’s” in perceived quality carwow.co.uk. However, one Aussie test did note some inconsistencies: e.g. slightly mismatched paint tone on plastic bumpers and some “jagged edges left behind” underneath – signs that BYD’s build process isn’t as polished whichcar.com.au whichcar.com.au. These don’t affect function, but show that Tesla (and Hyundai) have an edge in fit-and-finish. Still, the Seal’s cabin is quiet and well-insulated. And it wins style points with details like multi-color ambient lighting and unique “ocean aesthetics” design motifs.

Hyundai’s Ioniq 6 interior is all about modern comfort. It sports a twin-screen setup (a 12.3″ digital cluster + 12.3″ infotainment screen in one widescreen panel) with clean, friendly graphics whichcar.com.au. Unlike Tesla, Hyundai provides physical buttons for climate and audio – including toggle switches and a volume knob, which many users appreciate. (Car critics often lament that Tesla’s lack of physical controls, e.g. adjusting wipers or climate via touchscreen, can be distracting carwow.co.uk carwow.co.uk.) The Ioniq 6 strikes a balance: logical menu layouts on screen plus key shortcuts for essentials whichcar.com.au. One omission: at launch the Ioniq 6 still required wired Apple CarPlay/Android Auto (no wireless CarPlay) whichcar.com.au, though Hyundai is working on OTA updates to enable wireless CarPlay eventually. Materials in the Ioniq 6 are eco-friendly – lots of recycled fabrics, sustainable leather, etc. The fit and finish is excellent; no rattles, everything feels solid whichcar.com.au. Additionally, the Hyundai offers neat touches like relaxation mode seats (fully reclining front seats for napping while charging) and available digital side mirrors (in some markets) that replace door mirrors with cameras. Overall, the Hyundai’s cabin exudes a calming, lounge-like vibe, whereas the Tesla feels tech-forward and the BYD feels high-tech but with a traditional twist.

Infotainment & Connectivity: Tesla’s 15″ central screen remains a benchmark – its responsiveness and fluidity are top-notch. The UI is built around Google Maps navigation and includes Netflix/YouTube streaming, video games, Caraoke, and over-the-air software updates that can add features over time whichcar.com.au. However, no Apple CarPlay or Android Auto in Tesla carwow.co.uk – Elon Musk insists you use the built-in system. Most owners adapt to Tesla’s interface (which is generally intuitive), but if you live on smartphone integration, Tesla might irk you. BYD’s system doessupport Android Auto (wireless) and Apple CarPlay (oddly, CarPlay is wired-only on current software) whichcar.com.au. The Seal runs an Android-based OS with some quirks – menus are a bit confusing at first whichcar.com.au. The rotating screen, while novel, means the UI has to accommodate both orientations, which BYD’s software handles but not always gracefully. On the bright side, the Seal has a separate 10.25″ driver display (so you have a speedometer in front of you, unlike the Model 3) and even a color heads-up display on the windshield – features Tesla pointedly lacks carwow.co.uk. BYD also includes lots of USB ports (both A and C) and even a wireless phone charging pad. The Dynaudio 12-speaker audio in the Seal is decent, though reviewers call it “perfectly adequate” rather than spectacular whichcar.com.au.

Hyundai’s infotainment may not have fancy rotating tricks, but it is user-friendly with logical navigation and live traffic updates in the built-in nav whichcar.com.au. It does support both Android Auto and CarPlay (currently via cable). The Ioniq 6 also offers BlueLink connected services – an app that allows remote start, pre-heating/cooling, sending destinations to the car, etc whichcar.com.au. (Tesla’s app can do all that and more as well, very robustly; BYD’s app features are a bit more limited – you can lock/unlock, check battery, and even use an NFC key card, but you cannot drive away phone-only as a “digital key” yet whichcar.com.au.) The Ioniq’s available Bose 8-speaker audio is good, and it even offers fun features like speed-sensitive ambient lighting (the faster you go, the brighter the light strip glows – an interesting way to intuitively tell your speed). For tech nerds, Hyundai also has an augmented reality HUD option that projects turn-by-turn directions and safety alerts onto the windshield in front of the driver.

Seating & Space: All three sedans comfortably seat four adults, five in a pinch. The Model 3 has the roomiest feel for front passengers, partly due to that big glass roof and lack of dash clutter. In back, Tesla improved the 2024 Model 3’s rear seat padding and ergonomics whichcar.com.au, addressing complaints of a low bench. Still, rear headroom is only average – 6-footers’ heads graze the roof if they lean back (blame the sleek roofline). The BYD Seal is slightly longer than the Tesla, but its sloping roofline also limits rear headroom. Legroom is good in both, though the Tesla’s completely flat floor helps middle-seat comfort. The Ioniq 6 actually has the longest wheelbase (2,950 mm) whichcar.com.au and most rear legroom – it’s very generous for back-seat passengers, almost executive-sedan-like in RWD versions. However, the Hyundai’s roofline is lowest of the trio, which can make rear entry a duck-and-slide affair and tall people might feel the pinch on headroom as well. Where the Ioniq 6 shines is overall refinement: it’s extremely quiet at speed (acoustic glass, lots of sound insulation) and rides very smoothly, approaching luxury-car levels of comfort according to some tests carmagazine.co.uk.

In terms of cargo, the Model 3 is the clear winner. It’s a sedan with a huge secret: a liftback trunk opening and deep storage wells. With 561 L in the trunk plus ~85 L frunk space whichcar.com.au, the Tesla can swallow luggage for a family with ease – “a hundred years of carmaking experience can still be outclassed by a newcomer,” quips WhichCar, noting the Model 3’s cargo space embarrassed the others whichcar.com.au. The BYD Seal has a 400 L trunk (and 50 L frunk) whichcar.com.au – decent, but its trunk lid is smaller, making loading bulkier items harder whichcar.com.au. The Ioniq 6’s trunk is about the same (401 L plus a tiny 14 L front cubby) whichcar.com.au, and also a traditional sedan boot opening. All three have split-folding rear seats for longer items, though only Hyundai provides quick-release levers in the trunk (Tesla expects you to fold from the seat side). Notably, Tesla does not include a spare tire or even a tire repair kit(they assume you’ll call roadside assist), whereas BYD and Hyundai supply tire repair kits at least whichcar.com.au.

Notable Features: Tesla’s UI includes fun easter eggs and conveniences (dog mode, camp mode, sentry security mode using the car’s cameras, etc.). It also now has a rear 8″ screen for back-seat passengers (added in the Highland refresh) to stream media or control climate whichcar.com.au – a silver bullet for road trips, making the Tesla the most family-friendly in terms of in-car entertainment whichcar.com.au. The BYD Seal doesn’t have rear screens, but does give rear passengers their own climate vents and USB ports, as do most Ioniq 6 trims. Hyundai offers thoughtful touches like auto flush door handles (pop-out handles for better aero), and an available solar roof in some markets that can trickle-charge the battery (though it adds only a few miles of range on sunny days).

One potential downside for Tesla: the lack of a driver’s display means you have to glance at the center for speed/navigation – some drivers get used to it; others prefer the heads-up or cluster that Hyundai and BYD provide carmagazine.co.uk whichcar.com.au. Also, Tesla’s removal of stalks means even simple actions like indicating a turn or adjusting wiper speed require relearning muscle memory to use buttons or screen controls carwow.co.uk carwow.co.uk. Early reviews are mixed on this change – some call it “minimalism gone too far” carwow.co.uk.

In summary, tech lovers will enjoy Tesla’s bleeding-edge software and BYD’s gadgetry (rotating screen, etc.), while those who prioritize ease of use and comfort may lean toward Hyundai’s well-rounded approach (physical controls + digital features). Each car is packed with technology; it’s the philosophy of interface that differs.

Safety and Driver-Assistance

All three models come loaded with advanced driver-assistance systems (ADAS) and have top safety ratings. Crash Safety: Each earned a 5-star rating in Euro NCAP testing, with the Hyundai Ioniq 6 even named “Best in Class – Large Family Car” by Euro NCAP in 2022 hyundai.com. Tesla’s Model 3 has a slightly older NCAP rating (2018) but still excels; in U.S. NHTSA tests it got 5-stars across the board and a very low rollover risk. Hyundai and BYD, tested in 2022–2023, also achieved strong scores (the Seal scored 89% adult occupant, 87% child in Euro NCAP, comparable to Ioniq6’s 97%/87%). BYD’s robust battery-as-structure (cell-to-body) design likely contributes to its rigid safety cell byd.com.

Autopilot and Driving Aids: Tesla leads in some areas here – every Model 3 has the basic Autopilot (traffic-aware cruise control and lane-keep assist), and you can purchase the (expensive) “Full Self-Driving” (FSD) package which enables features like Navigate on Autopilot, Auto Lane Change, and Traffic Light/Stop Sign control. As of 2025, FSD is still Level 2 (hands-on) and occasionally controversial, but Tesla’s system for highway driving is generally very competent and gets better via updates. The Model 3 also offers a superb 360° camera system and a Sentry Mode for security recording. Oddly, it lacks a traditional blind spot warning in mirrors; instead, Tesla shows a live blind-spot camera feed on the screen when you signal.

Hyundai SmartSense: The Ioniq 6 includes a comprehensive suite: adaptive cruise with Stop&Go, lane-centering assist, blind-spot collision-avoidance (will actively steer you back if you attempt to merge into an occupied lane) edmunds.com, rear cross-traffic alert with auto-braking, and even Highway Driving Assist 2 on upper trims. HDA2 combines adaptive cruise and lane centering and can perform assisted lane changes when you signal – nearly on par with Tesla’s Autopilot in functionality. Hyundai also has an excellent blind spot view monitor – when you hit the turn signal, a camera feed from that side displays in the gauge cluster edmunds.com. The Ioniq 6 being an IIHS Top Safety Pick+ means its collision avoidance systems are among the best-tested. It also has parking collision avoidance, and on Limited trim, Remote Smart Parking Assist (you can inch the car forward/back out of tight spots from outside using the key fob).

BYD DiPilot: BYD equips the Seal with its ADAS suite called DiPilot, which includes adaptive cruise, lane-keep, blind-spot detection, and front collision warning with auto-braking. It’s functional but not as polished; some markets have reported that BYD’s lane-centering is a bit ping-pongy compared to Tesla/Hyundai’s smooth centering. BYD does have neat extras like an AR head-up display projecting warnings/navigation. One caveat: early UK reviews noted the Seal’s adaptive cruise could be overly cautious, and lane assist would sometimes disengage without clear reason – these may be early software kinks that updates will improve. All the basics (airbags, stability control, etc.) are of course standard on all three.

Lighting: The Model 3 and Ioniq 6 have full LED lighting with adaptive high beams. The Ioniq 6 offers Matrix LED headlights in some markets for “high beam assist” that can mask out oncoming cars – great for night driving. The BYD Seal also features matrix LED headlights with a cool double-U signaturebyd.com. In crash avoidance, all provide driver attention monitors; Hyundai goes further with an infrared camera for its SmartSense to monitor driver fatigue on some trims.

Interestingly, one recent safety recall (late 2023) affected the Tesla Model 3 in Australia: due to an oversight, the center-rear seat top-tether anchor was omitted in the new Model 3, meaning you couldn’t install a child seat in the middle position whichcar.com.au. Tesla issued a fix, but it’s a reminder that even small details matter. BYD and Hyundai have easily accessible child seat anchors (Isofix/LATCH) in both outer rear seats.

Overall, you can trust any of these cars with your family’s safety. Tesla’s approach is more software-centric (relying on cameras and neural nets for Autopilot), Hyundai uses a combination of cameras and radar, and BYD similarly. As for structural integrity, the BYD’s heavy battery and cell-to-body tech give it remarkable torsional rigidity (BYD cites 40,500 Nm/° stiffness, “equivalent to luxury cars”) byd.com. The Ioniq 6’s E-GMP platform also has a very strong passenger cell (with hot-stamped steels and a low center of gravity for stability). Each car also has electric-specific safety: e.g. battery disconnect pyrofuses in a crash, etc.

One more note: warranty and support – Hyundai typically offers excellent warranties (often 5-year vehicle and 10-year battery in the US). Tesla offers 4-year/50k mi vehicle and 8-year/120k mi battery warranty. BYD, as a newer entrant, has been offering around 6-year/150k km warranties in Europe for the Seal, with 8-year on the battery (specifics may vary by region). Check your local details, but Hyundai’s long warranty and established service network might give some buyers extra peace of mind over BYD’s still-growing support network.

Pricing and Value

When it comes to bang for your buck, each of these EVs makes a strong case in different ways. Here’s how the pricing generally breaks down (keep in mind regional differences are significant):

• Tesla Model 3 – Tesla has been aggressively adjusting prices. In the US, a RWD Model 3 starts around $40k(before any incentives), and the Long Range AWD around $47k, Performance ~$53k. Notably, the Model 3 qualifies for EV tax credits in the US (as of 2024, $3,750 for RWD LFP, $7,500 for Long Range) which can make it effectively cheaper than an Ioniq 6 which might not get full credits. In the UK, as mentioned, £39,990 for base RWD, £44,990 for Long Range RWD (yes, single-motor LR in UK), £49,990 for Long Range AWD, and £59,990for Performance independent.co.uk independent.co.uk. Tesla’s strategy often includes feature content standard – e.g. all have heated seats, premium audio (LR/Perf), basic Autopilot, etc. But you will pay extra for things like paint colors (only white is free), larger wheels, and of course the FSD software ($15k!). A big part of Tesla’s value is the Supercharger network access and strong resale value historically. Also, over-the-air updates may give your car new features over time for free, something legacy OEMs are just starting to emulate.
• BYD Seal – BYD has priced the Seal very competitively in markets like Europe and Australia. In China, the Seal undercuts the Model 3 by a decent margin. In Europe, the Seal Design (RWD) is around €44,900 (e.g. in Germany) and the Seal Excellence AWD ~€50,990 carnewschina.com. In the UK, as cited, £45,695 and £48,695 respectively independent.co.uk. That slots between the Tesla RWD and LR AWD prices, but note the Seal comes fully loaded in those trims – no options to add basically. You get the big battery even on the “cheaper” trim, plus features like the rotating screen, HUD, 360º cameras, 12-speaker audio, multi-color ambient lights, power seats, etc., all standard. BYD’s strategy is to offer a lot of value for money, appealing to feature-focused buyers. The Seal may still be pricier than some local brands (in Australia it’s under AU$70k, slightly below a comparable Model 3 Highland). Importantly, BYD does not yet sell in North America, so US buyers can’t get a Seal unless they import. In Europe and elsewhere, BYD is a newcomer, so while the price is good, factors like dealer network, unknown long-term resale, and brand perception (some may hesitate on a brand they’re unfamiliar with) play into value.
• Hyundai Ioniq 6 – Hyundai positioned the Ioniq 6 a bit upmarket from the Ioniq 5. In the US, the SE Standard Range starts at about $41k MSRP (before any dealer markups) edmunds.com. The Long Range RWD SE is ~$45k, SEL around $47k, and Limited AWD tops out around $56k. Hyundai EVs currently do not qualify for US federal tax credits (unless leased) due to being made in Korea, which affects their value proposition in America. In Europe, the Ioniq 6 Long Range starts ~€52k in many markets (it’s generally a bit pricier than a Model 3). In the UK, a mid-level Premium trim was ~£47k, going up to ~£55k for the top trim. Hyundai does justify some of that with lots of features and the Ioniq’s design prestige (remember, it won World Car Design of the Year worldcarawards.com). It also comes with Hyundai’s robust warranty and dealer service network, which some buyers value over Tesla’s direct-sales model.

Trim Differences: We’ve touched on this, but to summarize what you get by stepping up trims:

• Tesla: The base Model 3 RWD has ~220 miles EPA range (305 mi WLTP) and RWD performance, but still 0–60 in ~5.8 s and includes partial premium interior (heated front seats, basic audio). The Model 3 Long Range (whether RWD in EU or AWD in US) gives ~50% more range (up to 374 mi EPA / 634 km WLTP) carmagazine.co.uk, faster charging (because bigger battery can sustain it), and in AWD form does 0–60 in ~4.2 s. It also upgrades to the premium interior: better audio system, rear heated seats, etc. The Performance adds 20″ wheels, lowered suspension, track mode, and 0–60 in ~3.0 s – but at the cost of range (315 mi EPA). Many find the Long Range the sweet spot for Tesla.
• BYD: The Seal Design (RWD) gives you the 82 kWh battery, single 230 kW motor (~308 hp), all the bells and whistles inside (except maybe the second motor). It’s actually the longest range Seal variant at 354 mi WLTP independent.co.uk. The Seal Excellence AWD adds the front motor (total 390 kW/523 hp) and boosts acceleration to 3.8 s 0–100, but range drops to ~323 mi. It also adds some equipment like an upgraded sound system and possibly improved suspension tuning. In China, the lower-cost 61 kWh versions (called Dynamic trim) are more bare-bones: smaller battery, fabric seats, etc., aimed at a lower price point. BYD is targeting the higher end overseas with just the big battery for now. One reviewer advised that the “quicker model isn’t worth it” if you have to pay a lot more independent.co.uk – the RWD already has plenty of performance for daily use and better efficiency.
• Hyundai: The SE Standard is the budget pick – smaller battery, slightly less equipment (no heated seats in base SE Standard, for example), but it’s the most affordable way into an Ioniq 6. The SE Long Range adds the big battery; SEL brings extras like leatherette seats, wireless charging, Digital Key, and enhanced safety features edmunds.com. The Limited piles on with a sunroof, ventilated seats, Bose audio, surround-view cameras, HUD, Remote Smart Park, etc. edmunds.com edmunds.com. Opting for AWD on any trim adds ~$3,500 and gives you the 320 hp output and slightly lower range. Hyundai also recently introduced a cheaper trim in some markets (like Australia’s Dynamiq without some premium features to get the price under a certain threshold) whichcar.com.au. The good thing with Hyundai: even the base car has a solid suite of safety and convenience (dual screens, all driver assists, etc.) edmunds.com edmunds.com – you’re not missing fundamentals by spending less.

Value-add Features: Tesla’s value often is seen in its software and ecosystem (Supercharger access, frequent OTA upgrades). For example, owners got features like dashcam recorder, range improvements, and new entertainment options via free updates carmagazine.co.uk carmagazine.co.uk. Tesla also tends to hold good resale (though with recent price cuts, used values have softened). Hyundai’s value is in its build quality, dealership support, and awards (for those who care, it’s a World Car of the Year – a point Hyundai dealers will proudly mention). It’s also arguably the most unique-looking, which for some buyers adds intangible value. BYD’s Seal is value-packed with features per dollar, and being a new entrant, it often comes with attractive financing or warranty packages to build trust. In Australia, BYD aggressively priced the Seal “with a razor-sharp price” to undercut Model 3 whichcar.com.au. Early adopters of BYD may benefit from lower prices now before the brand gains recognition (BYD has been nicknamed the “Tesla of China” and as more people realize its cars are legitimately good, demand – and possibly prices – could rise).

One must consider charging infrastructure in value too: Tesla’s advantage is clear if you road trip often, as Superchargers are plentiful and easy – though note that Tesla is opening some Superchargers to non-Tesla EVs in Europe and starting in the US (Magic Dock adapters), which could let Ioniqs and BYDs charge there in the future. Hyundai owners rely on third-party networks (e.g. Electrify America, Ionity) which vary in reliability. BYD Seal uses the common CCS plug and in China uses their GB/T standard – in new markets, infrastructure is building but not as dense as Tesla’s proprietary network.

Insurance costs are another factor: typically, Tesla’s are a bit pricier to insure (due to high repair costs for aluminum body and tech-heavy parts), Hyundai should be moderate, BYD unknown but likely similar to other imports.

In summary, Tesla gives you cutting-edge tech and performance per dollar (especially if you value the charging network), BYD gives maximum features and a big battery for less money than rivals, and Hyundai gives a balanced package with quality and peace of mind, albeit at a slight premium. Which is best value will depend on what you personally value in a car.

Upcoming Models and Market Outlook

The EV sedan landscape is rapidly evolving. Here are some upcoming models and updates to watch, and how they could affect this trio’s battle:

• Tesla “Model 3 Highland” and Beyond: The Model 3 we’ve discussed is the newly refreshed version (codename Highland). Launched in late 2023 in Europe/Asia and early 2024 in North America, it brought improvements that keep the Model 3 fresh carmagazine.co.uk carmagazine.co.uk. But Tesla isn’t sitting still – rumors suggest a high-performance Model 3 “Track” variant or even a next-gen Model 3 Plaid could appear eventually, though nothing confirmed yet. More concretely, Tesla has been working on a next-generation platform for a smaller, even more affordable model (often dubbed “Model 2” by fans) to slot under Model 3 – if that comes by 2025–2026, it could attract budget-minded buyers, but it’s not a direct competitor to these midsize sedans. Another Tesla twist: the Model Y crossover continues to outsell the Model 3, as SUV body styles are popular – which might pressure sedans like these in the long run. However, Tesla’s focus on continuous improvement (e.g. recent addition of Hardware 4 self-driving computer, improved cameras) means the Model 3 will likely receive incremental upgrades without a full redesign for a few more years.
• BYD’s Next Moves: BYD isn’t just a one-hit wonder – they’re rapidly expanding their lineup globally. In Europe, after the Seal, BYD is introducing the Seal U, a larger hatchback/SUV, and has already launched the Atto 3 (Yuan Plus) SUV, Han luxury sedan, and others. A Seal convertible was shown in concept form (the BYD Ocean EV Convertible), though it’s unclear if that will reach production. What’s likely is a facelift or “Champion Edition”of the Seal in China for 2025 that tweaks range or features (BYD did this with some models, adding improved suspension and small feature gains reddit.com). Also, BYD’s premium sub-brand Denza and luxury offshoot YangWang indicate they’re serious about pushing technology. However, none of those directly compete with Model 3/Ioniq 6 price-wise. If anything, BYD’s biggest future threat to this segment might be more affordable EV sedans – they could leverage their cost advantage to introduce a slightly smaller sedan (perhaps a “Seal 2” or something) at a bargain price, undercutting everyone. For now, the Seal is BYD’s primary sedan play, and it will be interesting to see if BYD enters the North American market. If BYD finds a way into the US (possibly via partnership or local manufacturing to avoid tariffs), the Seal or its successors could seriously shake up Tesla’s home turf with value.
• Hyundai / Kia / Genesis: Hyundai’s next big EV sedan might actually come from its sister brand Genesis – the Genesis Electrified G70 is already out (a gas model conversion), but an electric G80 and other luxury sedans are in the works. Hyundai itself will launch the Ioniq 7, but that’s a large SUV. For sedan fans, a hotter version of the Ioniq 6 could be possible: Hyundai’s N division just released the Ioniq 5 N (an AWD performance crossover). An Ioniq 6 N sports sedan with ~600 hp, track suspension, etc., could theoretically appear if there’s demand – Hyundai has hinted that more N EVs are coming. If an Ioniq 6 N launches in late 2024 or 2025, it would target Tesla’s Performance model and possibly even outperform it on track (given how impressive the Ioniq 5 N is). On the tech side, Hyundai is continuously updating software – expect features like Plug&Charge, improved infotainment, and maybe Level 3 autonomy (they’re testing Highway Driving Pilot) to roll out in coming years on their EVs.
• Polestar 2 and 3, Volvo, Others: A key competitor in this segment has been the Polestar 2, which got a significant refresh for 2024 – switching to RWD for single-motor versions and boosting range and power carmagazine.co.uk carmagazine.co.uk. Polestar 2 sits between Model 3 and Ioniq 6 in price and has a hatchback design. CAR Magazine recently pitted the updated Polestar 2 against the Model 3 Highland and BYD Seal carmagazine.co.uk, finding the Polestar improved but still playing catch-up in range. Nevertheless, Polestar’s brand appeals to those wanting a Scandinavian design and Google’s Android Automotive OS. By 2025, the Polestar 2 (with up to 406 miles WLTP range now in long-range single motor form) carmagazine.co.uk will remain a strong alternative, and Polestar will also launch the Polestar 3 and 4 (SUVs) which could divert some sedan buyers.
• Volkswagen ID.7: Arguably the most direct upcoming rival to these three is the VW ID.7, a new electric sedan/wagon that’s a bit larger (mid-to-full-size). The ID.7 is launching in Europe in 2024 and in North America likely in 2025. It boasts a huge 86 kWh usable battery in its Pro S version and WLTP range up to ~700 km (435 miles) insideevs.com. In effect, the ID.7 could out-range even the Model 3 LR, and it’s positioned as a roomy, Passat/Arteon replacement – more interior space than the Ioniq 6, and a hatchback trunk like Tesla. It’s not as quick (single motor 282 hp, 0–100 ~6 s) insideevs.com, but a dual-motor GTX version (340 hp) is planned. VW is packing it with tech: 15″ central display, AR head-up, massaging seats, smart climate vents insideevs.com insideevs.com, etc. If you want a more conservative-looking sedan with tons of range and VW’s dealer network, the ID.7 will be compelling – though pricing is expected to start higher (around €55k in Europe) insideevs.com. The ID.7’s arrival will pressure Hyundai and Tesla at the upper end, especially for buyers who prioritize space and comfort over 0–60 times.
• Others: Don’t count out newcomers: Toyota showcased an EV sedan concept that promised game-changing battery tech (but that’s years away). Nissan may eventually reboot a Leaf/Ariya-based sedan. In China, besides BYD, there are impressive EV sedans like the Nio ET5/ET7 and Xpeng P7 – some of which are eyeing Europe. Nio ET5 in particular is a Model 3-sized sedan with battery swapping and a luxurious interior; if Nio enters Western markets more strongly, it could steal some thunder (it even offers a shooting brake/wagon variant in Europe). Lucid is launching the Air Pure at a higher price class, but a future Lucid mid-size model could trickle down tech. And let’s not forget BMW i4, Mercedes EQE (though those are pricier luxury segments) – they indirectly compete, at least demonstrating that legacy luxury brands are also present if you extend the budget.

The bottom line: competition is heating up. Tesla’s response to new rivals has been to cut prices and keep updating the Model 3 – expect them to continue aggressive pricing if needed (good for consumers!). BYD will leverage its manufacturing scale (they’re now one of the world’s biggest EV makers, even outselling Tesla globally in total plug-in cars carmagazine.co.uk) to push into more markets – their presence will likely force everyone to offer more for less. Hyundai (and Kia with its upcoming EV4/EV5) will emphasize design and reliability to justify their pricing. For consumers, the next year or two will bring more choices – including the possibility of an electric Volkswagen Passat (ID.7), a next-gen Nissan, or even a cheaper Tesla.

One interesting scenario: if Tesla opens up its Full Self-Driving technology or achieves true Level 3/4 autonomy, that could redefine value in this segment. Conversely, if charging standards unify (with Tesla’s NACS connector being adopted by others in North America), the playing field on charging convenience may level out.

In any case, the EV sedan showdown in 2025 won’t have just three contenders – but right now, the Model 3, BYD Seal, and Ioniq 6 are among the very best you can buy. Each is a mature, excellently engineered car that happened to come from very different backgrounds (Silicon Valley, Shenzhen, and Seoul!). It’s a fascinating battle to watch – and the real winners are consumers who get better cars at lower prices thanks to this competition.

Conclusion: Which One Should You Buy?

Ultimately, the choice between the Tesla Model 3, BYD Seal, and Hyundai Ioniq 6 will come down to your priorities:

• Choose the Tesla Model 3 if you value technology, performance, and charging convenience. The Model 3 remains a benchmark with its sporty driving dynamics and Tesla’s robust software ecosystem. It offers the longest real-world range in most scenarios carmagazine.co.uk and access to the unrivaled Supercharger network – a big plus for road warriors carwow.co.uk. The recent refresh adds refinement and keeps it feeling modern and luxurious inside. Downsides? The minimalist interior (no CarPlay, no gauge cluster) isn’t for everyone, and build quality, while improved, can still be hit or miss. But with Tesla continually improving features via updates and generally strong resale value, the Model 3 is a safe bet for an all-around superb EV that’s as fun as it is efficient. As one reviewer put it, “I like [the BYD Seal] a lot, but I like the Tesla Model 3 even more” carwow.co.uk – it’s a tough act to beat.
• Choose the BYD Seal if you’re a value seeker or tech enthusiast willing to try something new. The Seal delivers a lot of car for the money – a big battery, speedy acceleration (especially in AWD form), and a cabin loaded with premium features all included independent.co.uk independent.co.uk. It’s arguably the most eye-catching design of the three and will turn heads simply because it’s not another Tesla. The build quality is solid, and BYD’s Blade Battery tech offers peace of mind on safety and longevity byd.com byd.com. The Seal is an excellent cruiser too, with comfortable ride and quiet operation. However, the infotainment and brand experience aren’t as polished – BYD’s software has a learning curve whichcar.com.au, and its driver aids are a step behind. Also, BYD’s dealer/service network is still expanding in Western markets, so you’ll want to ensure you have support nearby. If you’re adventurous and want maximum features for your dollar (or if you simply dislike Elon Musk’s approach and want to support a Tesla rival), the BYD Seal is a compelling alternative that proves EV upstarts can compete toe-to-toe with the best carmagazine.co.uk. Just be prepared for a few quirks as the newcomer brand finds its footing.
• Choose the Hyundai Ioniq 6 if you appreciate comfort, style, and a proven track record. The Ioniq 6 offers a premium experience in many ways – a quiet, smooth ride, a beautiful and intuitive interior, and top-tier safety and reliability backed by Hyundai’s warranty. It may not win drag races against the clock, but it’s got ample power and by far the fastest charging for stress-free long trips edmunds.com. Its retro-futuristic aerodynamic design is not only striking but functional, delivering terrific efficiency and range southernteamhyundai.com. You also get niceties like a full array of driver assists that work quietly in the background to make every drive easier (the lane-centering and highway assist are among the best). The Ioniq 6 is the EV for those who want a bit of everything – good range, solid performance, comfort, and no sacrifices in convenience or after-sales support. On the downside, its price can be a little higher, and the availability might be constrained (Hyundai EVs have been in high demand). There’s also no performance variant yet to satisfy the need for speed. But given its accolades (World Car of the Year, etc.), the Ioniq 6 is a home run from Hyundai that delivers on its promises hyundai.news – an EV that’s easy to live with and easy to love.

In this “ultimate EV showdown,” there really isn’t a bad choice – and that’s testament to how far electric cars have come. The Tesla Model 3 remains the tech-forward driver’s car, the BYD Seal is the feature-packed disruptor offering maximum value, and the Hyundai Ioniq 6 is the design-savvy all-rounder with comfort and efficiency in spades.

Which one should you buy? The answer depends on what you personally prioritize:

• Crave the cutting-edge and a spirited drive every day? Go for the Model 3 – it’s still the one to beat for an engaging EV experience carwow.co.uk carwow.co.uk.
• Want the most bang for your buck and don’t mind driving something uncommon? Try the BYD Seal, and you’ll likely be pleasantly surprised at how much it offers for the price carwow.co.uk independent.co.uk.
• Prefer a comfortable, worry-free ownership with standout style? The Ioniq 6 will delight you with its blend of grace and tech, earning its title as 2023’s World Car of the Year hyundai.news.

Whichever you choose, you’ll be getting a glimpse of the electric future – one where range anxiety fades, charging is quick, and the joy of instant torque is part of daily life. The EV sedan segment in 2025 is hotter than ever, and as buyers, we finally have three excellent answers to the question: “What should my first (or next) electric car be?”

Happy driving – and welcome to the electric revolution!
