BYD SEALION 7 BUSINESS & PERSONAL CAR LEASING OFFERS

BYD revealed the Sealion 7 at the 2024 Paris Motor Show, and it arrived in the UK in March 2025 as the fourth model in the brand’s Ocean Series, following the Dolphin, Seal, and Seal U. It earned a five-star Euro NCAP safety rating the following month and was later named Best EV at the cinch Car of the Year Awards 2025.

The Sealion 7 arrived during a period of rapid growth for BYD. In May 2026 the brand announced it had become the UK’s largest electric vehicle brand, and it passed 100,000 UK registrations shortly after. Almost 38,000 of those came in the first half of 2026 alone. Every Sealion 7 comes with a six-year manufacturer warranty, and in January 2026 BYD extended its Blade Battery warranty to eight years or 155,000 miles.

For business customers who spend long days on the motorway, the Excellence AWD charges from 10% to 80% in 24 minutes at up to 230kW. Every version also sits in the 4% Benefit-in-Kind band for 2026/27. Personal customers benefit most from the 520-litre boot, a 58-litre front boot for charging cables, and heated and ventilated front seats on every trim. Vehicle-to-Load is standard too, so the car can power laptops, tools, or camping kit at up to 3.3kW.

- Fuel Type: Electric

- Electric Range: Up to 312 miles WLTP

- Key Specification

BYD Sealion 7 trims include:

- Comfort: The entry-level Sealion 7 is rear-wheel drive and uses an 83kWh battery, giving up to 300 miles of WLTP range and 0-62mph in 6.7 seconds. Standard equipment includes 19-inch alloy wheels, a panoramic glass roof, heated and ventilated front seats, heated rear seats, and the 15.6-inch rotating touchscreen. A 12-speaker Dynaudio sound system is also standard.

- Design: Adds a second motor for all-wheel drive and 390kW of combined power, cutting the 0-62mph time to 4.5 seconds. It keeps the 83kWh battery, so WLTP range is up to 283 miles. The main equipment upgrade over Comfort is a set of 20-inch bi-colour alloy wheels.

- Excellence: The range-topping Sealion 7 keeps the dual-motor performance of Design and adds a larger 91kWh battery, giving the longest WLTP range at up to 312 miles. It’s also the only trim that charges at up to 230kW, completing a 10-80% charge in 24 minutes. Inside, Nappa leather replaces vegan leather, and a head-up display is added.

Optional extras on the BYD Sealion 7 are limited to paint, because BYD fits most equipment as standard on every trim. Atlantis Grey is the standard finish. Indigo Grey, Polar White, and Space Black are available as cost options. Availability can vary by trim and current manufacturer ordering options.

Electric Performance

Every BYD Sealion 7 runs on BYD’s Blade Battery, a cobalt-free lithium iron phosphate (LFP) battery that BYD develops in-house. Its Cell-to-Body construction uses the top of the battery pack as the cabin floor, which adds structural stiffness and frees up headroom. LFP chemistry also handles temperature extremes and repeated charging well, helping the battery hold its capacity over time.

The entry-level Comfort pairs an 83kWh battery with a 308bhp rear motor, giving up to 300 miles of WLTP range and 0-62mph in 6.7 seconds. Design AWD adds a 215bhp front motor for a combined 523bhp and 0-62mph in 4.5 seconds, and it covers up to 283 miles WLTP. Excellence AWD keeps the same performance and steps up to a 91kWh battery, giving the longest range at up to 312 miles WLTP.

Comfort and Design AWD charge at up to 150kW, taking 10 to 80% in 32 minutes. Excellence AWD charges at up to 230kW, cutting this to 24 minutes. A heat pump comes as standard to protect range in cold weather. Towing capacity is up to 1,500kg braked on the all-wheel-drive versions and 750kg on Comfort.

Exterior Features

The Sealion 7 uses the same Ocean Series front design as the Seal, which pairs LED headlights with automatic high beam and a closed front panel. Flush door handles retract into the doors while driving, and a full-width LED light bar runs across the tailgate.

Comfort rides on 19-inch alloy wheels, and Design AWD and Excellence AWD move up to 20-inch bi-colour alloys. Every trim gets a panoramic glass roof with an electric sunshade, privacy glass on the rear windows, heated electric-folding door mirrors, and an electric tailgate with a kick-to-open function.

Interior Features

Inside, a 15.6-inch touchscreen rotates between landscape and portrait, and a 10.25-inch digital driver display sits behind the steering wheel. Excellence AWD adds a head-up display. A wireless charging pad sits at the base of the dashboard.

Comfort and Design AWD are trimmed in vegan leather. Excellence AWD upgrades to Nappa leather and offers a Tahiti Blue interior as an alternative to Black. Every trim includes heated and ventilated front seats, heated rear seats, and a heated steering wheel. The driver’s seat also has eight-way electric adjustment and memory.

The rear floor is flat, and there’s plenty of space for three adults. The boot holds 520 litres, or up to 1,789 litres with the 60:40 rear seats folded. A 58-litre front boot keeps charging cables separate from luggage.

Safety Features

The Sealion 7 scored the full five stars in Euro NCAP testing in 2025, including 87% for adult occupant protection and 93% for child occupant protection.

Every trim gets the same safety kit, so there’s no need to step up a trim for extra protection. Automatic emergency braking is standard, along with forward and rear collision warning, blind-spot detection, and lane-departure warning. Front and rear cross-traffic alert can also brake automatically if a vehicle approaches while you’re pulling out or reversing. A door opening warning alerts you to approaching traffic before you open a door. A driver monitoring system watches for signs of distraction or tiredness.

BYD’s DiPilot driver assistance suite combines adaptive cruise control and lane centring control to help with steering on motorways and in traffic, although the driver still needs to stay attentive and keep their hands on the wheel. It also has a 360-degree camera and front and rear parking sensors. The cabin has 11 airbags, including a front centre airbag between the two front seats. Child presence detection and ISOFIX points on the front passenger seat and outer rear seats are also fitted.

Business Leasing

A BYD Sealion 7 business lease suits company car drivers, directors, and fleet drivers who cover long distances. Fleet leasing with the BYD Sealion 7 gives businesses a spacious electric SUV for user-chooser lists and lower-emission fleet policies. Every trim carries the same safety and driver assistance kit, so drivers get the same protection whichever version they choose.

Personal Leasing

A BYD Sealion 7 personal lease lets you drive a new electric SUV for a fixed monthly payment, then hand it back at the end of your agreement. It suits families who need space for three in the back and a 520-litre boot. Even the entry-level Comfort includes heated rear seats, a panoramic roof, and up to 300 miles of WLTP range.

At the end of your agreement, you return the car, subject to the agreed mileage and our fair wear and tear guide. We can tailor BYD Sealion 7 leasing deals to your annual mileage, contract length, and initial rental, giving you fixed pricing for the term of your contract.

BYD Sealion 7 Salary Sacrifice

The BYD Sealion 7 is suitable for salary sacrifice. This can be a tax-efficient way for eligible employees to drive a new electric car, because payments come from gross salary before Income Tax and National Insurance are deducted. The Sealion 7’s Benefit-in-Kind rate of 4% for 2026/27 also keeps the taxable benefit low.

Salary sacrifice isn’t available to everyone by default. Your employer needs to have a scheme in place, and you’ll need to meet its eligibility criteria. Synergy can support businesses introducing or managing a salary sacrifice scheme, including adding electric SUVs such as the BYD Sealion 7 to the choices available to employees.
