BYD Seal U
The BYD Seal U is a spacious, family-oriented mid-size SUV that expands the Seal lineup into the highly lucrative family crossover segment. Available in the UK both as the pure-electric Seal U and the popular Seal U DM-i plug-in hybrid (combining a 1.5-litre petrol engine with an electric motor), it focuses heavily on passenger comfort, quiet cruising, and generous standard equipment. Initial reliability feedback is positive regarding powertrain smoothness, but owners report soft damping, over-anxious driver assistance alerts, and minor software quirks.
