The BYD Sealion 7 at a glance

The BYD Sealion 7 has quickly made a name for itself as a spacious electric SUV with reassuring safety and comfort features. Designed for families and drivers who value easy ownership and plenty of kit, it competes with favourites like the Tesla Model Y and Kia EV6, but offers its own blend of generous space, high interior finish and competitive pricing. Launched in the UK in 2024, it sits above the Atto 3 and Dolphin models, with three trim levels and two battery sizes, all five-seat configurations. Drivers appreciate its serene drive, ample rear legroom, reclining rear seats and extra boot storage, though it has modest rear headroom for tall passengers and is not as sharp to drive as some rivals.

Pros

Quiet, comfortable drive
Impressive standard safety kit
Spacious boot and clever storage

Cons

Limited rear headroom
Some models have slower charging
Not as much fun as some rivals

What our AA Mechanics think of the BYD Sealion 7

The BYD Sealion 7 is a confident and convincing electric SUV that shows just how far the brand has come in a short space of time. It offers strong performance, plenty of space and excellent technology for the money, making it a genuine alternative to more familiar names. While it’s not quite class-leading in every area, it manages to undercut several of its key competitors on price and is well worth considering.
