Audi is the first manufacturer to introduce an all-electric rally car to compete against conventionally powered vehicles in the Dakar Rally. During its debut at the Dakar Rally in 2022, the original RS Q e-tron won four stages, followed by its first desert rally victory at the Abu Dhabi Desert Challenge.
Let’s examine the characteristics of this electric-powered desert tamer. The RS Q e-tron E2 is an updated version of the RS Q e-tron that will compete in the 2023 Dakar Rally. The RS Q e-tron E2 is powered by three motor-generator units (MGU), one on each axle and one energy converter component. While driving, the third MGU helps to recharge the battery. Similarly, energy is recovered during braking. RS Q e-tron E2 is also equipped with a 2.0-liter four-cylinder turbo TFSI engine that is a component of the energy converter that charges the high-voltage battery while the vehicle is in motion.
Audi designed this innovative prototype with an extremely aerodynamic and lightweight frame. Steel tube frame combined with carbon fiber components helps reduce the weight and center of gravity of the prototype, thereby improving the aerodynamics and performance of the drive train.
