The BYD Seal 6 is a five-seat plug-in hybrid family car offered as a saloon or an estate, with a 1.5-litre petrol engine, front-wheel drive and a choice of battery sizes. This page explains the body styles, the powertrain and the Boost and Comfort trims so you can choose the right version before you look at the deals below.
The BYD Seal 6 is a five-seat family car sold as a saloon or an estate, and every version is a plug-in hybrid. At 4.84 metres long it sits in the traditional mid-size family class, and it is one of the few cars in that class you can still have as a plug-in saloon rather than an SUV.
It sits apart from BYD's other Seal models in the UK range. The Seal 6 keeps a petrol engine for long trips while still plugging in for short ones, which suits drivers who aren't ready to go fully electric.
The choice is refreshingly short: two body styles, one plug-in hybrid petrol powertrain, and two equipment levels. That's it.

Manufacturer data for the versions we currently offer. Last updated 5 October 2026.
The Seal 6 is a plug-in hybrid family car built around space, equipment and running costs rather than driving thrills. It seats five, carries 491 litres in the saloon or 500 litres in the estate, and comes with a 6-year / 93,750-mile manufacturer warranty.
Reviewers consistently praise how much kit you get as standard and how efficient the hybrid system stays once the battery is empty. The common criticism is ride comfort: road testers note the Seal 6 can feel unsettled on poor British surfaces, and several find the touchscreen menus fiddly.
Safety is a strong point. Euro NCAP awarded five stars, with 92% for adult occupant protection and 90% for child occupant protection.
Two shapes, same length and same wheelbase. The saloon is the four-door with a conventional boot lid; the estate is the five-door with a bigger seats-folded capacity. Mechanically they share the same engine and battery options.
The four-door holds 491 litres with the seats up and 1,370 litres folded. The boot is deep, so awkward loads can be trickier than in the estate. Kerb weight runs from 1,665 kg.
The five-door estate takes 500 litres seats up and 1,535 litres folded, with a 75 kg roof load rating. It's slightly heavier, from 1,710 kg.
Because the standard specification is unusually complete and the warranty is long, which matters on a lease where you want predictable years rather than surprises. Every Seal 6 gets adaptive cruise control, keyless entry and start, and a digital instrument cluster.
Driver assistance is fitted across the range: autonomous emergency braking, blind-spot monitoring, rear cross-traffic alert, lane-keep assist, traffic sign recognition and automatic high beam, plus a rear-view camera and rear parking sensors. Apple CarPlay, Android Auto and DAB radio are standard too.
Practical details help day to day: a 65-litre fuel tank, an 11.0 m turning circle and an electric parking brake. Servicing falls every 12 months or 10,000 miles, and insurance groups run from 33 to 36, so it's worth getting a quote before you order.
There's only one powertrain family here, so the real decision is which battery size and trim combination suits you.
A 1.5-litre four-cylinder petrol engine works with a battery of up to 19.0 kWh, giving 181-209 bhp, 300 Nm and front-wheel drive through a single-speed automatic. It plugs in for electric running and refuels like any petrol car when the battery's flat, so no charger at home isn't a dealbreaker.
Performance is adequate rather than quick: 0-62 mph takes 8.5-8.9 seconds and top speed is 112 mph. The best version charges at up to 26 kW, taking 23 minutes from 30-80%, or 2.7 hours from 15-100% on a 6.6 kW home wallbox. If you mostly do short local trips, the larger battery earns its keep. Our electric and hybrid guides cover how plug-in charging works in practice.
| Plug-in hybrid | |
|---|---|
| Boot | 491–500 litres |
| Power | 181–209 bhp |
| Seats | 5 |
| Battery | 10.1–19 kWh |
| 0–62 mph | 8.5–8.9 s |
Two equipment levels run through the range, and the higher one brings more power as well as more kit.
The entry version has 181 bhp, front-wheel drive and 17-inch monochrome alloy wheels, with artificial leather upholstery, LED headlights, a vegan leather multifunction steering wheel, Apple CarPlay and Android Auto, and a reversing camera.
Same 181 bhp mechanical package, the same 17-inch monochrome alloys and the same artificial leather trim, with a powered tailgate and roof rails added. That pairing is aimed squarely at people who load the car up regularly.
Steps up to 209 bhp and 18-inch monochrome alloy wheels, and adds an opening panoramic roof, a 360-degree camera, front parking sensors, ventilated and heated front seats, a heated steering wheel, electric seat memory, wireless phone charging, privacy glass, ambient lighting and an auto-dimming rear-view mirror.
The same upgrade applied over BOOST: 209 bhp, 18-inch monochrome alloys, opening panoramic roof, 360-degree camera, front parking sensors, heated and ventilated front seats, heated steering wheel, seat memory, wireless charging, privacy glass, ambient lighting and auto-dimming mirror.
