Summary
The BYD Seal is an all-electric executive saloon and the third model BYD has launched in the UK. As the brand’s flagship model, the Seal poses direct competition to the likes of the Tesla Model 3, BMW i4 and Polestar 2.
“On price and equipment alone, the BYD Seal is an attractive proposition”, says Dave Humphreys of The Sunday Times, who adds that the car also drives with a similar degree of quality and finesse to its established rivals.
Car‘s Keith Adams explains that the Seal is more efficient than the BMW i4, more responsive than the Hyundai Ioniq 6, and has a higher interior quality than the Tesla Model 3. That said, Adams also concludes in his Parkers review that “the BMW i4 outdrives it, the Hyundai Ioniq 6 is more comfortable, and the Polestar 2 has a funkier interior and better infotainment.”
John McIlroy of Auto Express says that BYD has “a real star on its hands”, praising the saloon for its “generous” standard equipment list, its “solid” battery range and “respectable” charging speeds. On the other hand, several reviewers comment that the car’s rather intrusive safety assistance systems need some work. Evo‘s Sam Jenkins says this tech may prove to “be a sticking point for many.”
As of January 2025, the BYD Seal holds a New Car Expert Rating of A, with a score of 76%. It gets top marks for its excellent safety rating and it produces zero tailpipe emissions. Please note, however, that the overall rating is still incomplete as we are awaiting full running cost data, and we obviously won’t get any meaningful reliability data for some time as the Seal is a brand-new car.

“The BYD Seal is an impressive package whether one highlights performance, specification or price. It’s without doubt a rival to Tesla.”

Model reviewed: Range overview
Score: 8 / 10
“The BYD Seal feels like a mature product and more than lives up to its “next-generation” billing. But with that comes a tangible price premium that puts the sleek saloon on par with (or even slightly above) rivals, rather than allowing it to undercut them as before. Don’t let that dissuade you, however. This is a well-equipped, high-quality, admirably efficient and good-to-drive EV that stacks up well both on paper and in the real world.”

“As good as the BYD Seal looks, feels and performs, given the ultimate convenience and the exclusivity of Tesla’s charging network, we suspect BYD will still have an uphill battle for hearts and minds if it is to upstage Tesla’s EV pre-eminence.”

“The BYD Seal is a convincing proposition against a Model 3, Polestar 2, BMW i4 or Ioniq 6. It’s more efficient than the BMW, more responsive than the Hyundai, roomier than the Polestar and better built than the Tesla. That is quite a reflection of the astonishing pace the Chinese motor industry has moved towards a dominant position in the electric car market.”

Model reviewed: Range overview
“The BYD Seal is an electric saloon car that looks to have all the right ingredients to take on the all-conquering Tesla Model 3 – indeed, if the Chinese maker can get the price right, it could even beat the industry stalwart at its own game. Strong range, decent practicality, an agreeable drive and plenty of kit set the BYD Seal up very nicely indeed.”

Model reviewed: Excellence
“Quick charging is becoming easier in my part of the world, and the BYD Seal made light work of this while I grabbed a coffee. Checking the numbers for the BYD Seal Excellence also showed it has stayed true to its claims about mileage and range. What you see on the screen is what you will get on the road, which is very unusual with EVs in my experience. That alone makes the BYD Seal one of my favourite electric cars.”

“Many people may have preconceptions about cars from Chinese companies that are new to the UK, for example in terms of the expected levels of quality. The BYD Seal should dispel such myths. It’s excellent to drive, the interior has a premium feel, and it features BYD’s Blade battery, which promises a 300-mile+ range along with high levels of safety. And then there’s the Seal’s competitive price. So manufacturers of other electric saloons should take BYD and its Seal seriously.”

“Not everyone will take the BYD Seal seriously (its biggest obstacle is probably its name), but you only need to look at MG to see that Chinese electric vehicle manufacturers have the potential to shake up the UK market. But with a long range, superb interior finish and lots of standard equipment, we think the BYD Seal is a surprisingly appealing choice.”

“On price and equipment alone, the BYD Seal is an attractive proposition so it’s a welcome bonus that it also drives mostly with a similar degree of quality and finesse as its closest rivals, though some improvement is required in its driver assistance systems.”

No eco rating
As of January 2025, the BYD Seal has not been tested by Green NCAP.
The Green NCAP programme measures exhaust pollution (which is zero for an electric car) and energy efficiency. Electric cars are much more energy-efficient than combustion cars, so the Seal is likely to score very highly in Green NCAP testing whenever it ever takes place. Check back again soon.

The BYD Seal is not the cheapest electric car to run, according to whole life cost data provided exclusively to The Car Expert from our data partner, Clear Vehicle Data.
Electrical efficiency (the EV equivalent of miles per gallon or a diesel or petrol car) is only average, although a large battery means that driving rage is still excellent between recharging stops.
Insurance costs are high, although this is likely to improve as insurance companies get more real-world data about claims from BYD customers compared to other brands.
