Audi RS Q e-tron

The Audi RS Q e-tron E2¹ is the second evolution of 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 original Audi RS Q e-tron¹ scored four stage wins during its debut at the Dakar Rally in 2022 and shortly thereafter won its first desert rally at the Abu Dhabi Desert Challenge. Audi is 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 at the Dakar Rally. The innovative prototype presents itself significantly improved for the 2023 Dakar Rally and now bears the abbreviation E2 following its evolution during the second phase of the development program.

The distinguishing aspects of the Audi RS Q e-tron E2¹:

  • Utilizes an innovative drivetrain concept²
  • High-voltage battery is charged while driving via an energy converter²
  • Three motor-generator units (MGU), one on each axle and one part of the energy converter²
  • Futuristic prototype that is now in its second evolution stage
  • Fundamentally new body optimizes weight and airflow
  • Improved operating strategy and optimized control concept
  • The battery weighs about 370 kilograms and has a capacity of around 52 kWh

Innovative drivetrain concept²

Because there are no charging opportunities in the desert, Audi has chosen an innovative charging concept: On board of the Audi RS Q e-tron E2¹, there is the highly efficient 2.0 liter four cylinder turbo TFSI engine from the DTM. It is part of an energy converter that charges the high-voltage battery while driving.

 

The drivetrain of the Audi RS Q e-tron E2¹ 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 52 kWh.

Second evolution

The Audi RS Q e-tron E2¹ is lighter, more aerodynamic and even more efficient. The body is completely new and features significantly enhanced aerodynamics. It helps lower the prototype’s weight and center of gravity. New operating strategies further improve the efficiency of the electric drivetrain. In the interior and when changing wheels, the driver and co-driver benefit from easier operation. Following these evolutions, the RS Q e-tron now bears the abbreviation E2. It is reminiscent of the legendary Audi Sport quattro in its final development stage for Group B rallying in the 1980s.
