The new MGU inverter unit from Audi weighs less than 35 kilograms. This represents a significant weight saving compared to the previous powertrain. The Audi Sport technicians made this possible by using lightweight materials, among other things. “This was an extraordinary team effort by all of those involved,” says project manager Stefan Aicher.

A key factor in this progress was also the extensive work carried out on the company’s in-house test benches. In numerous extremely demanding material test cycles, the drivetrain was loaded to its limits to raise the entire high-voltage system to a maximum performance level. “If you compare our new MGU to a combustion engine with a comparable output of 250 kW, our efficiency is not only twice as high, but our weight of under 35 kilogrammes is also many times lower,” emphasizes Tristan Summerscale. “This clearly shows what an efficient solution an electric drivetrain is.”

The Brazilian is and will remain one of the firm fixtures at Audi Sport and in Formula E. With 32 podiums, 10 wins and 796 points in the first six seasons, Lucas di Grassi is more successful than any other driver in the all-electric racing series. In addition to the race track, di Grassi is also a committed ambassador for electric mobility. His victory at the Formula E premiere in Beijing in 2014, becoming the drivers’ champion in 2016/2017 and clinching the team’s title with Audi Sport ABT Schaeffler in 2017/2018 will remain unforgotten.
