BYD Sealion 7 review: the Model Y rival that's eating into Tesla's lead

How the BYD Sealion 7 fits in 2026

The Sealion 7 landed in Australia in February 2025 as BYD’s Tesla Model Y rival, and by early 2026 it had done exactly what it set out to do — become the second best-selling EV in the country, with only the Model Y itself outselling it. It sits in the medium-SUV bracket alongside the Kia EV5, Hyundai Ioniq 5, XPeng G6 and BYD’s own (smaller) Sealion 6 PHEV.

What’s changed since launch is that BYD has gone from “the new Chinese brand” to a top-three EV seller in Australia, and reviewers who initially withheld judgement have circled back with more time in the car. The verdict is consistent across six Australian reviews: this is the most polished Chinese EV currently on sale here.

We’ve focused on the Premium ($54,990 list, around $59,857 drive-away) for this review — it’s the volume seller and the variant most third-party reviewers have tested. For prices and specs across both trims, see the full Sealion 7 lineup on its model page.

What’s good

The ride and handling are genuinely sorted. Multiple Australian reviewers — CarExpert, carsales, EV Central and The Driven — independently call out the Sealion 7’s suspension tune as a step up from earlier Chinese EVs. The tune leans European-firm rather than soft, with composed body control on flowing roads and confident bump absorption. carsales rated the ride-and-handling package “surprisingly nuanced”. This is not a sports SUV — most reviewers note it’s competent rather than engaging — but it doesn’t punish you for hitting a mid-corner bump.

The interior is the strongest argument for the price. Quilted leather seats (heated and ventilated up front), a 15.6-inch rotating touchscreen, Dynaudio audio, dual digital displays and a head-up display are all standard on the Premium. EV Central and carsales both describe the cabin as having a “sincerely luxury pretension” that the $54,990 list price doesn’t suggest.

Practicality is class-competitive. A 500L boot plus a 58L frunk, generous rear legroom and 2,930 mm wheelbase give the Sealion 7 the family-SUV credentials it’s marketed on. ANCAP rated it five stars on 2025 test protocols, and BYD’s 8-year / 160,000 km battery warranty remains class-leading.

What’s not

Real-world range falls well short of WLTP. The Driven, the only review to publish detailed real-world figures, observed ~23 kWh/100km on highway runs — translating to roughly 360 km of usable range against the 482 km WLTP claim. City driving was closer to 19 kWh/100km. That’s a 25% highway shortfall, which is at the wider end of the EV-segment norm. Most reviewers flag energy consumption as “okay rather than good”.

DC fast charging tops out at 150 kW. That’s fine for a 32-minute 10-80% stop, but it visibly trails 800V rivals like the XPeng G6 (215 kW) and the Korean Ioniq 5 / EV6 family (235 kW). For buyers who do regular interstate trips, the gap shows up at every fast-charger stop.

The infotainment hides too much. EV Central, CarsGuide and Chasing Cars all flag the same issue: critical functions like seat heating and ventilation are buried behind touchscreen menus. The three-finger swipe shortcuts help, but the rotating screen and physical buttons can’t fully compensate. One reviewer (Chasing Cars) also found the lane-keep assist over-eager and difficult to live with on country roads. There’s no spare tyre — repair kit only — which carsales calls out as a meaningful omission for regional buyers.

Where it lands among rivals

• BYD Sealion 7 vs Tesla Model Y. The Model Y RWD lists at $71,990 — a $17,000 gap. The Tesla is more efficient (14.6 kWh/100km vs the Sealion’s ~19), charges faster (170 kW), and gets Supercharger access. The Sealion 7 has the longer warranty (6/8 years vs Tesla’s 4), the better interior trim, and undercuts so heavily that for many buyers it’s not really a comparison.

• BYD Sealion 7 vs Kia EV5. The EV5 lists from $56,770 and goes 555 km WLTP — a meaningful range advantage — with Kia’s 7-year warranty. The Sealion 7 is quicker (6.7s vs 8.5s 0-100), has the more upmarket cabin, and tows the larger boot. The EV5 is the rational pick for long-distance commuters; the Sealion 7 wins on perceived quality.

• BYD Sealion 7 vs XPeng G6. The G6 undercuts at $48,990 list and brings 800V architecture with 215 kW DC charging. The Sealion 7 has the bigger battery, more space, longer warranty, and the more developed dealer network. The G6 is the road-tripper’s pick; the Sealion 7 is the family-buyer’s.

Who should buy one

• Households cross-shopping a Tesla Model Y who want similar size and equipment for $15,000+ less.
• Family buyers who prioritise interior space, perceived quality and a long battery warranty.
• Suburban commuters whose driving is mostly under 300 km a day with home charging.
• Buyers who’d rather have a calm, comfortable EV than a fast or dynamic one.

Who should pass

• Regional and interstate drivers who want fast DC charging — the 150 kW peak will frustrate.
• Range-anxious buyers who’ll do regular 400 km+ highway runs without charging stops.
• Anyone who wants a connected, engaging steering feel — the Sealion 7 is competent, not sporty.
• Drivers who can’t tolerate touchscreen-buried climate controls.

What I’d want for next year

The hardware is in good shape — the obvious MY27 priorities are software. I’d want the climate and seat-heating shortcuts on a permanent on-screen tile rather than buried in menus, the lane-keep assist calibration softened to match Korean and Japanese norms, and DC charging dialled up to at least 200 kW. A factory tow-rated spare wheel option wouldn’t hurt either.

Verdict

The Sealion 7 Premium is the strongest evidence yet that a Chinese mid-size EV can credibly play in the same bracket as the Tesla Model Y, Kia EV5 and Hyundai Ioniq 5 — and undercut all of them on list price while doing it. Real-world range and DC charging are the obvious compromises, but the chassis tune, interior finish and standard equipment are good enough that six Australian reviewers have independently arrived at scores in the 7.8-8.1 range. At $54,990 list, that’s a fair buy.
