Audi aims to become the first automotive manufacturer to deploy an electric drivetrain with a highly efficient power generator, enabling it to compete and win against conventional internal combustion engine vehicles in the world’s toughest rally.
The unique challenges of the Dakar Rally demand exceptional engineering, as the event spans two weeks with daily stages reaching up to 800 kilometers in length.
To overcome the impossibility of charging batteries in the desert, Audi’s RS Q e-tron is equipped with a high-efficiency TFSI engine used in Germany’s touring car championship. This engine serves as part of a power generator that recharges the high-voltage battery during driving. Operating efficiently between 4,500 and 6,000 rpm, this combustion engine achieves fuel consumption below 200 grams per kilowatt-hour.
The RS Q e-tron features an electric drivetrain with motor-generator units on both front and rear axles. These units are derived from the current Audi e-tron FE07 Formula E race car developed by Audi Sport for the 2021 season, adapted slightly to meet Dakar Rally requirements.
The RS Q e-tron also differs significantly in exterior design from traditional Dakar rally cars. Juan Manuel Díaz, Head of Audi’s Race Car Design Team, said: “The vehicle showcases a futuristic, advanced design, incorporating many signature elements of Audi’s design language.” He added, “Our goal was to embody our brand’s philosophy of progress through technology and express the future of our brand.”
The prototype of the RS Q e-tron was first unveiled in Neuville at the beginning of July. Audi’s schedule from now until year-end includes an intensive testing program, culminating in the first international rally competition tests.
