Audi Sport has revealed its new e-tron FE07 race car for Formula E 2021 season, which starts in Chile in mid-January. Lucas di Grassi and René Rast will drive the FE07 car #11 and #33, respectively.
For the new powertrain, Audi claims an overall efficiency of more than 95%. According to Tristan Summerscale, Formula E Project Leader at Audi Sport, “the new MGU inverter unit has an efficiency of even more than 97% in all relevant driving conditions”.
“If you compare our MGU with an internal combustion engine delivering a comparable power output of 250 kW (340 hp), our efficiency is not only twice as high, but our weight of less than 35 kg (77 lbs) is also much lighter,” added Summerscale.
The race car is claimed to sprint from 0-100 km/h (62 mph) in 2.8 seconds and on to a top speed of 240 km/h (149 mph). Full technical specifications here.
