Summary
The BYD Seal 6 is a mid-sized saloon and ‘Touring’ estate range, and the petrol plug-in hybrid counterpart to the all-electric BYD Seal.
Officially named the Seal 6 DM-i – ‘DM-i’ being the moniker BYD gives to its plug-in hybrid models, standing for ‘Dual Mode Intelligent’ – the saloon and estate line-up has divided the British motoring media to date, with criticisms of the plug-in hybrid range generally outweighing the positives.
Journalists Alan Taylor-Jones and Luke Wilkinson have published multiple reviews of the Seal 6 across several titles, the pair’s Car reviews concluding that the BYD’s unrefined handling and “thrashy and unpleasant” powertrain means that the Seal 6 “desperately needs to go back to finishing school”, despite the car’s attractive pricing and practicality.
On the other hand, Steve Fowler of The Independent gave the range a much higher review score, praising the saloon and estate for its “excellent” interior quality and its “refined and relaxing” driving experience.

Warranty on a used BYD Seal 6
- If you are buying an ‘Approved Used’ BYD Seal 6 from an official BYD dealership, you will get the remaining balance of the original six-year new car warranty and the eight-year battery warranty, and if the warranty is up, you get a minimum 12-month warranty included.
- If you are buying a used BYD Seal 6 from an independent dealership, any warranty offered will vary and will probably be managed by a third-party warranty company.
- If you are buying a used BYD Seal 6 from a private seller, there are no warranty protections beyond any remaining portion of the original new car warranty.
If you’re looking to buy any used car that is approaching the end of its warranty period, a used car warranty is usually a worthwhile investment. Check out The Car Expert’s guide to the best used car warranty providers, which will probably be cheaper than a warranty sold by a dealer.
