BYD Sealion 7 UK review: the £44,990 Chinese EV that makes the Model Y explain itself

Tesla spent years telling us nobody could undercut the Model Y on price and beat it on kit. Then BYD parked a 530hp, 312-mile coupe-SUV on UK forecourts from £44,990 and quietly dared everyone to argue. When BYD confirmed UK pricing and specifications for the Sealion 7 ahead of its Q1 2025 on-sale date, the numbers read less like a launch and more like a provocation aimed squarely at Stuttgart and Fremont.

A year on, the Sealion 7 is no longer a curiosity: it is one of the genuine reasons a UK buyer cross-shopping a Model Y now has a harder decision than they expected. So let me lay out where it lands, where it stumbles, and who I’d actually point towards it.

The pricing is the headline, and it should be

Three trims, and each one tells you who BYD is hunting. The Comfort RWD opens at £44,990, the Design AWD sits at £49,290, and the range-topping Excellence AWD lands at £57,290, all on-the-road. Those figures, set out in full by BusinessCar’s specs-and-prices breakdown, are not the story on their own. The story is what comes attached to them.

Even the entry car gives you a 15.6-inch rotating central screen, dual-zone climate, heated seats, wireless phone charging and vehicle-to-load, the trick that lets the car power an external device or appliance from its own battery. None of that is reserved for the dear models. That is a deliberate strategy: load the base car so heavily that the premium German rival’s options list starts to look like an insult.

Before you choose, line the three trims up against each other, because the right answer is not the obvious one.

530 horsepower for the price of a warm hatchback’s worth of options

The Comfort RWD makes a perfectly civil 313hp. Step up to either AWD car and you get 530hp, 0–62mph in 4.5 seconds and a 134mph top speed. For context, that is supercar-baiting acceleration in a family-shaped EV that will still swallow the weekly shop.

The 530hp cars get the headlines, but the road testers who have actually driven it are lukewarm on whether you need them. Both Electrifying and the RAC frame the Sealion 7 as a comfortable, sensible family EV rather than a back-road weapon, which squares with the spec. A 4.5-second launch flatters a car in a showroom and matters far less on a damp British commute, and the AWD hardware adds weight and cost the everyday driver rarely cashes in. On the numbers, the cheapest, lightest RWD car is the one that reads as the most resolved of the three.

The 530hp cars are the ones that get the headlines. The 313hp car is the one I’d sign for.

Range and charging: respectable, not class-leading

Here is the first place the Tesla comparison gets uncomfortable for BYD. The Sealion 7’s WLTP figures, as listed by BYD’s own UK configurator, run to up to 300 miles for the 82.5kWh Comfort RWD, up to 283 miles for the Design AWD on the same battery, and up to 312 miles for the 91.3kWh Excellence AWD.

Those are solid real-world-adjacent numbers, but they do not lead the class, and the Design AWD’s 283-mile figure is the one that gives me pause: you pay more, you go faster, and you travel less far than in the cheaper car. Charging helps the case. Up to 230kW DC means a 10–80% top-up in as little as 24 minutes, which on a long run claws back some of the range deficit, provided you can find a charger that will actually deliver it. That last clause matters more than the headline kW: a 24-minute stop is a marketing figure, and the British rapid network outside the big motorway hubs still does not reliably hand you 230kW on a wet Tuesday.

Space where it counts

The practical case is stronger than the badge snobs will admit. At 4,830mm long, the Sealion 7 offers a 520-litre boot that expands to 1,789 litres with the rear seats down, plus a modest 58-litre front trunk for charging cables. That is proper family-SUV usability, and the frunk, small as it is, keeps the muddy cables out of the main boot, which anyone who has lived with an EV appreciates more than they expected to.

The company-car angle is where it really bites

There is one more reason the Sealion 7 lands harder than its spec sheet suggests, and it is the reason CDE readers ask about most: company-car tax. As a pure EV it sits in the lowest benefit-in-kind band, so a higher-rate taxpayer taking one through a salary-sacrifice scheme pays a small fraction of the monthly hit a petrol equivalent would trigger. I am not going to quote a rate here, because the BiK percentage steps up each tax year and your figure depends on your salary, your scheme and your tax band: check the current HMRC company-car tax rates before you commit, and treat any broker’s headline monthly as representative, not a finance offer, with your rate subject to status. The direction of travel is clear, though. On salary sacrifice, a £44,990 list price turns into a monthly number that makes the Sealion 7 look sharper still against a Model Y.

That route also tidies up the Sealion 7’s one real weakness. BYD is still building its used-value story in the UK, and resale is the genuine unknown: a Model Y has years of depreciation data behind it, the Sealion 7 does not. If you are buying outright, treat that as a reason to haggle and a reason to favour the higher-range Comfort or Excellence cars that hold appeal. If you are leasing or salary-sacrificing, depreciation is not your problem, which is exactly why this car suits that route so well.

So is it really the Tesla killer?

No. And I think calling it one does the Sealion 7 a disservice, because it sets it up against the one car it cannot quite out-range. What it does instead is something arguably more dangerous for the establishment: it makes “premium” feel less exclusive. The reviewers have largely agreed. Electrifying’s verdict and the RAC’s road test both frame it as a seriously credible mainstream EV rather than a budget curiosity, and that framing matters. This is not a cheap car wearing a brave face. It is a well-equipped one priced with intent.

What would stop me? The middle child. The Design AWD asks £49,290 for less range than the £44,990 Comfort RWD, with the only real upside being the 530hp drivetrain most buyers will rarely fully use. If I am spending close to fifty grand, I would rather have the £57,290 Excellence’s bigger battery and longer legs, or I would pocket the difference and take the entry car.

What I’d do with my own money

I’d buy the Comfort RWD and never look back. It is the sweet spot of this range: 313hp is more than enough, 300 miles is the best range in the line-up, and you keep the rotating screen, the V2L, the heated seats and the wireless charging that make the cabin feel like a car costing far more. The AWD performance is a lovely party trick, but it costs you money, range and a little composure, and I don’t think the everyday Sealion 7 needs it.

The buyer I’d steer away? Anyone whose week revolves around long, charger-sparse motorway runs: there are EVs that will simply go further between stops, and the Sealion 7’s quick charging only partly answers that. But for the UK family doing a daily commute, the school run and the occasional long weekend, and especially for the higher-rate taxpayer eyeing a salary-sacrifice deal, this is the car that makes a £50k German rival explain itself. A year ago that would have sounded far-fetched. It doesn’t any more.
