The BYD Sealion 7 is a five-seat electric SUV with a 520-litre boot, a six-year warranty and up to 312 miles of WLTP range. This page explains the Comfort, Design and Excellence trims and helps you pick the right one to lease.
The BYD Sealion 7 is a five-seat electric SUV. It suits families and company drivers who want a lot of standard kit, a quiet cabin and a real-world family boot, without a fuel card.
It sits near the top of BYD's UK line-up: 4.83 metres long, five doors, 520 litres of boot space with the rear seats up and 1,789 litres with them folded. Every version is electric and automatic.
The choice is simple. One body, one electric powertrain family with a rear-wheel-drive or all-wheel-drive layout, and three trims: Comfort, then the 523 bhp Design and Excellence.

The Sealion 7 is BYD's electric SUV, sold in one five-seat body. It's a comfort-first car rather than a sporting one, despite the power figures.
Reviewers consistently praise the cabin quality, the driving position, the rear legroom and the sheer amount of equipment fitted as standard. The common criticism is ride and handling: road testers find the body control loose over poor surfaces and the steering short on feel.
What's less arguable is the ownership package. You get a six-year or 93,750-mile manufacturer warranty, an eight-year or 125,000-mile battery warranty guaranteeing 70% of capacity, and a five-star Euro NCAP rating with 93% for child occupant protection.
Because the specification gap between the cheapest and dearest Sealion 7 is unusually small, so you're not forced up the range to get the kit you actually use every day. Servicing is every 24 months or 20,000 miles, which keeps a three-year contract simple.
Every version has adaptive cruise control, a 360-degree camera, an opening panoramic roof, heated and ventilated front seats, heated rear seats, a heated steering wheel, wireless phone charging, built-in navigation, Apple CarPlay and Android Auto, a heat pump and a hands-free tailgate.
Safety kit is standard across the board too: autonomous emergency braking, blind-spot monitoring, rear cross-traffic alert, lane-keep assist, traffic sign recognition and front and rear parking sensors. Practicality is helped by a 5.9-metre turning circle and a fixed towbar on every version.
There's one answer here: the Sealion 7 is electric only, with an automatic drive and a choice of rear- or all-wheel drive. No petrol, diesel or hybrid version is offered.
Battery capacity runs from 82.5 kWh to 91.3 kWh, power from 309 bhp to 523 bhp, and WLTP range up to 312 miles on the best version. Charging at up to 230 kW takes the best version from 30-80% in 18 minutes; a home wallbox does 0-100% in 8.6 hours at 11 kW. New to this? Our electric car guide covers the basics.

Comfort is the one most drivers should look at first, because it carries nearly all the equipment; Design and Excellence are about power, wheels and trim rather than a longer kit list.
The entry version: 309 bhp, rear-wheel drive, 19-inch alloy wheels, artificial leather upholstery, LED headlights, navigation, Apple CarPlay and Android Auto, plus the panoramic roof with its electrically adjustable sunshade. It also has a powered tailgate and rear-view camera. The Comfort is currently available from £342.35 a month.
Then come the two high-output versions, both with 523 bhp and all-wheel drive.
Design keeps the Comfort's equipment and changes the character: 523 bhp, all-wheel drive and 20-inch alloy wheels in place of the 19s, with artificial leather upholstery. Think of it as the Comfort with a front motor and a bigger footprint. The Design is currently available from £444.10 a month. Against the Comfort, that is currently £101.75/mo more expensive.
Excellence is the same 523 bhp all-wheel-drive setup on 20-inch alloys, adding real leather upholstery and a head-up display. The Excellence is currently available from £500.05 a month. Against the Design, that is currently £55.96/mo more expensive.
If you're cross-shopping, the Škoda Enyaq and Volkswagen ID.4 cover much the same ground, while the Leapmotor C10 and OMODA 5 are the other newer-brand options. The rest of the BYD range is worth a look too.
