In spite of announced officially retired from Formula E races, BMW i Drivetrain will power the Andretti Formula E team in season 8.
Andretti Formula E announced that they will use the BMW Racing eDrive03 drivetrain as an independent team.
Ahead of the current season, the drivetrain was homologated for another two years, meaning that it is available for the team to use for one more season.
The BMW Racing eDrive03, which is being used in Seasons 7 and 8 as the BMW i drivetrain in Formula E, has benefited from detailed improvements when compared to its predecessor. Thanks to experience gained over the past few years, it has been adapted to deal even more adeptly with the unique challenges posed by Formula E circuits. The main goal of the modifications is to improve the efficiency of the drivetrain. The E engine attains a maximum efficiency of 98 percent and its power density is higher than 14kW/kg. Its maximum rotational speed is more than 30,000 rpm. The inverter works with a direct current of up to 900 volts and achieves a power density of more than 45 kW/kg. In this latest version, the carbon inverter housing has been replaced by one made of Kevlar.
