Audi Sport is making an attempt one thing new in 2022 with an try on the Dakar Rally utilizing this wild-looking creation.

It is referred to as the Audi RS Q e-tron and is a collection hybrid that mixes parts from Audi’s DTM race automobile and Audi’s Method E automobile.

Two Method E engines drive the wheels, and a 3rd is related to a 2.0 L, four-cylinder turbo from the DTM automobile. These two cost the battery whereas the RS Q e-tron is on the transfer.

Audi Sport has drafted Mattias Ekström as one in every of its drivers.

The RS Q e-tron has been designed to be simple to work on, because the Dakar takes place in distant areas with little assist.

Testing started firstly of July and can proceed for the remainder of 2021.

Audi’s DTM program—assume the German equal of NASCAR—ended on the finish of 2020, and 2021 is the German automaker’s ultimate 12 months in Method E. However the funding that Audi Sport made in each these applications won’t go to waste, as features of every are combining to energy an outrageous-looking machine designed to compete within the Dakar Rally. Unveiled on-line at the moment, the automobile known as the Audi RS Q e-tron, and Audi says that campaigning it in one of many world’s hardest off-road races will let the corporate check and develop its electrical powertrains “below excessive situations.”
Though Audi’s racing exploits have principally taken place on the confines of race tracks for the previous few a long time, the model has a powerful hyperlink with rallying; it used the World Rally Championship within the Eighties to show its quattro all-wheel-drive know-how. They could each contain rallying, however Dakar is a more durable problem than the WRC, because it’s contested over two weeks in distant locations, with distances of 500 miles (800 km) a day.
“That is a really lengthy distance,” says Andreas Roos, who’s chargeable for the Dakar mission at Audi Sport. “What we try to do has by no means been finished earlier than. That is the last word problem for an electrical drivetrain.” Commercial

The character of the Dakar dominated out a purely battery-electric strategy, though such a factor has been tried prior to now. As a substitute, Audi Sport has gone for a collection hybrid strategy—and sure, collection hybrid followers, we predict this one passes the purity check.
Three Method E MGUs and a DTM engine stroll right into a bar…
The tube-framed RS Q e-tron makes use of a pair of 250 kW (335 hp) electrical motor/generator items (MGUs) from Audi Sport’s present Method E program, one mounted at every axle. These are fed by a 52 kWh (useable) lithium-ion battery pack which will have been borrowed from an Audi e-tron FE07 Method E automobile. Whole energy output is 500 kW (670 hp).
Then there is a third Method E MGU, which types a part of the vitality converter that fees the battery whereas the RS Q e-tron is on the transfer. (The 2 propulsive MGUs may also regenerate vitality below braking.) The opposite element of the vitality converter is a 2.0 L TSFI engine from Audi Sport’s DTM automobile, which is related to that third MGU by a shaft. You won’t count on a extremely strung racing engine to work properly as a generator, however Audi Sport says the engine is definitely extremely environment friendly when in the appropriate rev vary.
“We diminished the output from 450 to about 200 kW. It operates inside the slender optimized rpm vary of between 4,500 and 6,000, as a substitute of 9,000 rpm,” mentioned Stefan Dreyer, head of growth of motorsport initiatives at Audi Sport. “The engine has to run as effectively as potential within the warmth, chilly, and at altitude. We optimized the pistons, injectors, and turbocharger for this and spent loads of time on the check bench. We’re pleased with the precise consumption that’s properly below 200 grams per kWh.”Commercial

“The drivetrain is extraordinarily environment friendly. There’s hardly any energy loss. You don’t should count on temperature issues whilst you’re driving slowly within the sand. However above all, the electrical drivetrain is way simpler to regulate in all the given conditions,” Dreyer mentioned. “The utmost torque is offered from zero revolutions. You’ll be able to regulate the drivetrain very exactly, whether or not the automobile goes over jumps or driving within the desert. The electrical drivetrain doesn’t react to exterior influences corresponding to air stress, temperature, and humidity. And you should utilize it at full energy all through the rally. It’s all way more constant than with a combustion engine.”

The RS Q e-tron may also be recharged every evening. Though Audi Sport hasn’t proven off the charging answer simply but, it says it plans to make use of as a lot clear vitality as potential. And the automobile has been designed to be extremely serviceable by a small assist workforce.

The prototype RS Q e-tron first bought its toes muddy firstly of July, and it is now present process an in depth check program for the rest of the 12 months, earlier than the 2022 Dakar Rally, which takes place in Saudi Arabia subsequent January.
Audi Sport will enter three RS Q e-trons run by Q Motorsport. One automobile will probably be shared by Mattias Ekström (who received DTM and Rallycross championships for Audi) and Emil Bergkvist, one by 14-time Dakar winner Stéphane Peterhansel and Edouard Boulanger, and the third by Carlos Sainz (double WRC champion in addition to three-time Dakar winner) and Lucas Cruz.
