With the RS Q e-tron E2 Audi goes on a hunt for the Dakar 2023

Cars News

Audi is preparing for the Dakar 2023 with a new version of the RS Q e-tron that has been completely revised compared to the one that last year, in its absolute debut, had won four wins and ten podiums at the Dakar 2022. The new racing car is calls the RS Q e-tron E2, with the additional abbreviation that refers to the final phase of development of the Audi Sport quattro Group B of the 1980s. The first commitment of E2 will be the Morocco Rally in October, after which the German team’s commitment will focus on the Dakar, which will start on 31 December 2022 and will end on 15 January 2023 in Saudi Arabia.

The bodywork has been redesigned to be more aerodynamic and lighter but also to have a lower center of gravity; the energy management system has become more efficient even in extreme conditions and the passenger compartment is more spacious and functional.

“The RS Q e-tron E2 does not share a single body component with the first generation of the car. We are radically reducing the overall dimensions of the lower section of the rear bonnet, to the left and right of the B-pillars. the masses, ”explains Axel Löffler, Head of Design for the Audi RS Q e-tron. In the future, T1U category prototypes will have to weigh 2,100 kilograms against the previous 2,000 kg. Since the first generation of the Audi RS Q e-tron was characterized by a weight above the regulatory minimum, several tens of kilograms could be saved.

“Aerodynamics should not be underestimated in rally raids. By regulation, the maximum speed is limited to 170 km / h. What changes is the energy requirement which is now lower, because the aerodynamic drag has been reduced by 15%. We have achieved this thanks to computational fluid dynamics, that is the development through computer simulations rather than in the wind tunnel, with consequent advantages in terms of speed and precision of analysis ”adds Löffler. The powertrain, on the other hand, does not change: there are two electric MGUs – one for each rear axle – plus a heat engine that creates the necessary electricity. The latter is derived from the 4-cylinder TFSI which is used in the DTM, the German Touring Championship.
