Test laboratory in the desert
The Audi RS Q e-tron¹ is the contender from the brand with the four rings for one of the greatest challenges that there is in international motorsport: the Dakar Rally. The futuristic prototype made its competition debut at the 2022 Dakar Rally and scored four stage victories and 14 stage podium results.
Audi wants to be the first car manufacturer to use an electric drivetrain in combination with an efficient energy converter² to compete for overall victory against conventionally-powered competitors in one of the world’s toughest rallies.

Highlights of the Audi RS Q e-tron¹
Audi RS Q e-tron¹
The distinguishing aspects of the Audi RS Q e-tron¹:
- Futuristic prototype with innovative drivetrain concept²
- High-voltage battery is charged while driving via an energy converter²
- Three motor-generator unit (MGU), one on each axle and one part of the energy converter²
- The battery weighs about 370 kilograms and has a capacity of around 50 kWh
- The efficient combustion engine has a specific consumption of below 200 grams per kWh

Because there are no charging opportunities in the desert, Audi has chosen an innovative charging concept: On board of the Audi RS Q e-tron¹, there is the highly efficient TFSI engine from the DTM. It is part of an energy converter that charges the high-voltage battery while driving. Since the combustion engine is operated in the particularly efficient range of between 4,500 and 6,000 rpm, the specific consumption is well below 200 grams per kWh.
The drivetrain of the Audi RS Q e-tron¹ is electric. The front and rear axles are both fitted with a motor-generator unit (MGU) from the Audi e-tron FE07 Formula E car. Only minor modifications had to be made to use the MGU in the Dakar Rally.
A third MGU, of identical design, is part of the energy converter and serves to recharge the high-voltage battery while driving. In addition, energy is recuperated during braking. The battery weighs about 370 kilograms and has a capacity of around 50 kWh.
