Will the BYD SEAL U DM-i use as much as the WLTP says in real life?
The WLTP is a test under fixed conditions, meant to compare cars fairly. Speed, temperature, traffic and driving style decide what you really use; so we do not quote a “real-world consumption”, which would be an estimate no official source confirms.
