Audi Formula Racing GmbH
Audi Formula Racing GmbH (AFR) in Neuburg an der Donau, near the Audi headquarters, was founded specifically for the Audi F1® Project. At AFR, the powertrain (hybrid drive including transmission) is developed and manufactured in close cooperation with the Hinwil site. The Audi F1® Power Unit, labelled ‘AFR 26 hybrid’, consists of the V6 internal combustion engine (ICE) with 1.6-liter displacement and turbocharging, an energy recovery system (ERS) including energy storage (ES) and electric motor-generator unit (MGU-K) as well as an electronic control unit (CU-K). This powertrain, which runs on advanced sustainable fuels, reflects the development of Formula 1® towards greater sustainability. This was a prerequisite for the involvement of Audi.
