BYD Seal U Business & Personal Car Leasing Offers

BYD has grown quickly in the UK, first building its passenger car range around electric models such as the Atto 3, Dolphin and Seal. The Seal U moves the brand into the plug-in hybrid SUV market, using BYD’s Super DM system to combine electric driving with petrol support for longer trips.

The Seal U DM-i takes the Seal name into a larger, more practical SUV shape. It uses BYD’s Super DM plug-in hybrid system, pairing a 1.5-litre petrol engine with an electric motor and Blade Battery. This gives drivers useful electric range for shorter journeys, with the petrol engine adding flexibility for longer trips.

It appeals to BYD Seal U business lease customers who want a plug-in hybrid SUV with low CO2 emissions and a strong Benefit-in-Kind position. It also works well for BYD Seal U personal lease customers looking for a spacious, comfortable and well-equipped family SUV. With useful electric range for everyday journeys and petrol power for longer trips, BYD Seal U leasing suits company car drivers, families and drivers covering mixed mileage.

- Body Type: SUV

- Fuel Type: Plug-in hybrid

- Electric Range: Up to 78 miles WLTP

- Seats: 5

- Boot Size: Up to 425 litres

Key Specifications

BYD Seal U leasing includes three trims:

- Boost: Entry-level trim comes well equipped as standard. Includes 19-inch alloy wheels, LED headlights, rear privacy glass, panoramic sunroof, heated steering wheel, heated and ventilated front seats, vegan leather upholstery, a 12.3-inch digital driver display, 15.6-inch rotating touchscreen, head-up display, wireless phone charging, Infinity sound system and a 360-degree camera.

- Comfort: Keeps the same generous equipment as Boost, while adding the larger 26.6kWh Blade Battery. This increases electric range to up to 76 miles, making it the strongest choice for drivers who want to make regular use of the Seal U’s plug-in hybrid system.

- Design: Design sits at the top of the range and gives the Seal U its most powerful set-up. It adds all-wheel drive, increases power to 319bhp and reduces the 0-62mph time to 5.9 seconds. Electric range is lower than Comfort, although Design will appeal to drivers who want stronger performance and extra traction from their BYD Seal U lease.

Optional extras are kept simple, with the main choices focused around trim and colour. BYD lists Time Grey, Snow White, Sky Blue and Delan Black for the Seal U, while the key decision for most BYD Seal U lease deals is whether to choose Boost for value, Comfort for the longest electric range or Design for all-wheel drive performance.

Engine & Performance

The Seal U is available exclusively as a plug-in hybrid, using BYD’s Super DM system. Boost and Comfort pair a 1.5-litre petrol engine with an electric motor and automatic transmission, producing 217bhp and 300Nm of torque. Both are front-wheel drive and accelerate from 0-62mph in 8.9 seconds. Boost uses an 18.3kWh Blade Battery for up to 50 miles of electric range, while Comfort uses a larger 26.6kWh battery for up to 78 miles.

Design is the more powerful option. It uses a 1.5-litre turbocharged petrol engine, two electric motors and all-wheel drive, increasing output to 323bhp and 550Nm of torque. It can accelerate from 0-62mph in 5.9 seconds and has an electric range of up to 43 miles. CO2 emissions range from 9g/km to 23g/km depending on version, which makes the Seal U DM-i especially relevant for company car drivers comparing a BYD Seal U business lease and Benefit-in-Kind costs.

Exterior Features

You’ll find BYD’s Ocean Design styling on the outside, with a softer SUV shape than the lower Seal saloon. The front end features double U-shaped LED headlights, while the rear uses a full-width light bar with a water drop-style matrix pattern.

All trims include 19-inch bi-colour alloy wheels, aluminium roof rails, an electric tailgate, LED headlights, automatic headlights, rear privacy glass and a panoramic sunroof with an electrically adjustable sunshade. This gives the Seal U a strong standard specification from Boost upwards, which helps BYD Seal U lease deals feel good value across the range.

Interior Features

Inside, there’s a focus on comfort and everyday practicality. The cabin has a floating centre console with useful storage, vegan leather seats and a heated steering wheel. Heated and ventilated front seats are standard, with electric adjustment for both front passengers and memory adjustment for the driver.

The rear seats offer a flat floor and good passenger space, making the Seal U suitable for family use as well as business mileage. Boot space is 425 litres, increasing to 1,440 litres with the rear seats folded, while 40:60 split-folding rear seats give the car useful flexibility for luggage, shopping or work equipment.

Safety Features

Every trim includes front, side, curtain and front centre airbags, Tyre Pressure Monitoring System, emergency call, child presence detection and ISOFIX with i-Size points for the front passenger seat and outer rear seats.

Driver assistance technology is also generous across the range. The Seal U includes front and rear parking sensors, a 360-degree camera, Adaptive Cruise Control, Intelligent Cruise Control, Lane Keep Assistance, Blind Spot Detection, Lane Change Assist, Traffic Sign Recognition and Automatic Emergency Braking. Front and rear cross traffic alert with braking support is also included, helping with visibility.
