Audi has revealed the new version of the Audi RS Q e-tron, which carries the E2 addition to the name as a tribute to the legendary Sport Quattro from Group B of the World Rally Championship. Lighter, more aerodynamic, and even more efficient: this is how Audi Sport presents the prototype in the T1U category in a nutshell. It has a completely new body, which plays a key role in the improved aerodynamics and overall weight reduction. Engineers have managed to reduce aerodynamic drag by about 15 percent. However, this has no effect on the top speed of 170 km/h, as it is limited electronically to meet FIA (Fédération Internationale de l'Automobile) requirements. More importantly, however, the improved aerodynamics contribute to increasing the machine's energy efficiency.

The car uses a complex propulsion system that consists of an internal combustion engine, a generator, a high-voltage battery and two electric motors for each of the axles. To optimize the operation of the entire power train, engineers make additional adjustments to the power train, which allow a limit to be imposed on the power supplied by the electric motors. This is necessary because at the Dakar 2022 Audi was fined for overspending 2 kilojoules [kJ] of energy due to the work of the electric motors when the car jumps or has poor traction. The RS Q e-tron E2 has also received improved air conditioning and servo pump management to achieve lower power consumption. In October in Morocco, the Audi Sport team will begin the real part of the car's preparation for the 2023 Dakar Rally.

Auto Trendy’s take:

This vehicle must have been a great challenge for Audi, given the fact they are just debuting in the Rally Dakkar. Their first attendance at the famous desert rally will be in early 2023 and we are curious to see their performance. We should not forget that they have a reputation to uphold, and that is the reputation of the legendary Sport Quattro S1 built for Group B rallying in 1984.
