BMW Motorsport has released some details of its first all-electric powertrain which it will use during the coming ABB FIA Formula E Championship season.
Dubbed the Racing eDrive01, the powertrain brings together technical expertise of both BMW Motorsport and also BMW i, the manufacturer’s electrical engineering sub-brand.
The Munich-based marque says that “engineers from motorsport and production development have incorporated the knowledge and experience of BMW i in a high-performance motorsport drivetrain.”
Initial design and production work on the drivetrain began in early 2017 in the same prototype construction facilities as the next generation of BMW road-going i series cars.
BMW says that “more than a quarter of the pre-development team is also working on the Formula E project” and that the first test bench runs for the Racing eDrive01 were conducted in the summer of 2017.
The first track test took place at one of the manufacturer’s regular proving grounds at Maisach in Germany with Tom Blomqvist undertaking the first miles.
This was a slightly delayed first run after plans to join other manufacturers at the Monteblanco circuit in Spain at the end of March were halted due to teething issues.
BMW has carried over several key figures from Andretti which has metamorphosed into the BMW i Andretti Motorsport team.
These include Roger Griffiths, who has been retained as team principal, as has BMW’s head of track engineering Tim Malyon who was seconded to the team in 2017.
Former Techeetah team manager Campbell Hobson also joined the team in the summer and replaces Rob Arnott who left in June.
As revealed by e-racing365 in May, the Magna group is working with BMW on aspects of its maiden Formula E car.
The global automotive giant has already built several BMW road car models at its Magna Steyr plant in Graz, Austria.
The company has extensive experience in both hybrid and electrical engineering solutions including work on the BMW 5 Series plug-in hybrid range from 2017 onwards.
BMW has been consistently vocal in evidencing what it calls “the experience of production engineers during its development, the knowledge gained by BMW i Motorsport engineers in the tough competitive environment of Formula E flowed straight back into the development of future E-drives for BMW production vehicles.”
