Summary
The BYD Sealion is a mid-large electric SUV that sits at the top of the ever-expanding BYD family. It was unveiled in 2024 before arriving in the UK in early 2025.
The Sealion 7 is related to the BYD Seal saloon, although it uses a more advanced version of the Seal’s platform, including more advanced electric motor and drive technologies for better performance and efficiency.
Initial media reviews for the BYD Sealion 7 have been disappointing. Despite praise for its spacious cabin and decent levels of kit for the money, several reviewers have pointed out that the Sealion 7 is more expensive and not as good to drive as a Tesla Model Y.
The ride and handling of the Sealion 7 have also been questioned by several reviewers, with Darren Cassey from Carwow describing it as “not very comfortable” and Dean Gibson from Auto Express pointing out that it “doesn’t drive as sweetly” as some alternatives.
On the positive side, it has an excellent safety rating according to testing by Euro NCAP, scoring a full five stars when tested in April 2025.
As of January 2026, the BYD Sealion 7 holds a New Car Expert Rating of A, with a score of 72%. It scores top marks for its excellent safety rating, zero tailpipe emissions and long new car warranty, but its running costs are only average and its media review scores have been poor.

“The Sealion 7, slightly odd name aside, is well equipped, has decent range and performance, and is comfortable and quiet. A bit more polish in some areas would elevate it even higher, but as it stands the BYD Sealion 7 is well worth consideration.”

“Anyone who has concerns over the quality of the driving experience of Chinese EVs needs to try the BYD Sealion 7. It offers a driving experience that’s extremely comfortable as well as powerful, along with the security of its all-wheel drive system. The cabin also looks good and feels high quality, with lots of rear legroom and a large boot.”

“The Sealion 7 is the latest car to emerge in BYD’s assault on the European establishment. It’s impressive in many ways, but there are a fair few kinks that need to be ironed out before it can truly be taken seriously against similarly priced, better-known rivals.”

“While the BYD Sealion 7 is able to compete with similarly priced but more established rivals, its sub-par ride and handling, plus some tech-related annoyances, mean it can’t be heartily recommended over better-known alternatives. And don’t get us started on the name…”

“So much for these Chinese brands undercutting rivals – the new BYD Sealion 7 is more expensive than its big rival, the new Tesla Model Y. It also doesn’t go as far on a single charge. So being more expensive and with a smaller range immediately count against the BYD, and then you drive it, which might put you off even more.”

“The BYD Sealion 7 is a strong contender as an alternative to the Tesla Model Y, with a premium feel, powerful performance in dual motor form, plenty of interior space, and strong technology. The handling is light but overall, well worth considering if you’re after a midsize electric SUV.”

The BYD Sealion 7 isn’t the cheapest EV to run, but if you can charge from home then it should still be considerably cheaper than a similarly sized petrol or diesel SUV.
The insurance group rating is quite high, so make sure you shop around for car insurance quotes as it could make quite a difference.

In addition to the standard new car warranty, the Sealion 7 has an eight-year/125,000-mile warranty for the battery components.
