BYD SEAL U
Design electric FWD automatic
Examined here is the BYD SEAL U. This is the third vehicle from this Chinese brand to be tested by Green NCAP. The car is a large SUV offering a high level of comfort and 500 km driving range as type approved in the WLTP cycle. This range is possible thanks to a battery with 86 kWh usable capacity and the official consumption of 20.5 kWh/100 km, a figure confirmed by Green NCAP's tests. Green NCAP reveals the vehicle's consumption values in demanding situations not covered by homologation, such as the high-load highway cycle and the -7°C Cold Ambient Test. Both scenarios are particularly challenging for a large SUV, as the high aerodynamic drag takes its toll on motorway consumption, and the spacious cabin combined with high comfort demand requires more energy for heating. Naturally, the SEAL U consumption results are higher, but still in the expected range.
The vehicle was also tested in real-world driving on the street, where it recorded 21 kWh/100 km at 24°C ambient temperature on dry road. BYD could further improve the efficiency of the onboard charger. With 11 kW charging, some 88-89% of the recharged energy withdrawn from the charging socket is normally available at the output of the battery, while Green NCAP measured approx. 87% with the SEAL U. Overall, the vehicle receives an Average Score of 93% and 5 Green Stars. More detailed information can be found in the datasheet.
