Audi has shared many more; information about RS Q e-tron , his electric prototype with range extender with which he will race; the Dakar 2022. In addition to providing the first photos of this special vehicle, the house of the 4 rings has also announced that the tests have finally started. To better prepare for the Dakar, the car will participate by the end of the year; even to some rally raids. The technical specifications that have been disclosed are very interesting.
The powertrain of the Audi RS Q e-tron has three units & agrave; electric derived from those of the Formula E Audi e-tron FE07 single-seater. Specifically, two MGUs (Motor Generator Units) are located at each axle and take care of traction. The third unit, on the other hand, acts as a generator to help recharge the battery, especially when braking. Since the car will have to tackle difficult routes, the powertrain & egrave; been structured to withstand heavy stresses.
RANGE EXTENDER FOR ELECTRICITY 
The maximum power of the system reaches 680 hp (500 kW) , even if at the level of the regulation it is not the level of power that will be able to be defined has still been defined; be used during the Dakar. The traction is; obviously integral and exploits the operation of the electric motors placed on the axles of the car. Therefore, there is no classic drive shaft and central differential, all to the advantage of reducing the masses.
Since in the middle of the desert you can't; refuel, Audi has chosen to integrate a range extender which will be & agrave; used during the special tests exclusively to generate energy for the 50 kWh battery (weight of 370 kg). It is a four-cylinder TFSI turbocharged gasoline direct injection, derived from the DTM. The development and management of the electrical prototype will be; edited by the Q Motorsport team together with Audi Sport.
With this prototype, Audi is aiming for victory in the Dakar. For this, he wanted to entrust the three cars that he will bring; competing for the drivers St & eacute; phane Peterhansel, Carlos Sainz and Mattias Ekstr & ouml; m . These are well known names within the motorsport world. Audi RS Q e-tron will be; & quot; exploited & quot; also as a laboratory for mobility; electric of the future. What has been learned will be then poured on the future battery models of the German brand.
