## Is the BYD Seal 6 DM-i worth considering?

The 19 kWh Comfort is the version to look at, with 65 miles of WLTP electric range in the UK and DC charging, while the Boost has 34 miles and AC charging only. It earned five Euro NCAP stars, but no independent range or fuel test was found, so real-world economy is unconfirmed.
