BYD Sealion 6: range, price, specs and where it is sold

Facts checked

The Sealion 6 is the plug-in hybrid version of the SUV China calls the Song Plus, and it carries more names than any other BYD model. China sells it as the Song Plus DM-i, Europe and the United Kingdom as the Seal U DM-i, Australia and Japan as the Sealion 6, and Mexico and Brazil under the Chinese name. Australia's Sealion 6 badge was a late change from a planned Seal U.

European cars pair a 1.5-litre engine with an 18.3 kWh Blade battery. The front-drive Boost is quoted at 80 km of WLTP electric range and 1,080 km combined from 160 kW; the all-wheel-drive Design at 70 km and 870 km from 238 kW. Australian and Brazilian cars use a larger 26.6 kWh pack. Chinese figures are quoted on the older NEDC cycle at 51 or 100 km electric and up to 1,200 km combined, so they are not comparable with the European numbers.

Safety testing followed an unusual route. Euro NCAP crash-tested the battery-electric Seal U in 2023, and ANCAP extended that five-star result to the Australian plug-in hybrid after additional frontal-offset and pole tests, publishing 88 per cent for adult occupant protection. Brazil was the first export market, in November 2022, and the car has since reached Mexico, Europe, Australia, Thailand and Japan.
