Audi is taking its electrified powertrain technology to one of the most grueling races on the planet. It will compete in the 2022 edition of the Dakar Rally with an experimental gasoline-electric hybrid off-roader named RS Q E-Tron.
While several models in the German firm’s line-up wear the E-Tron label, the Dakar-bound RS Q is a purpose-designed prototype that’s not in any way related to a production model. It was developed for racing from the ground up in about a year, and it’s a way to test several clever features that could trickle down to future models later on.
Audi selected a hybrid drivetrain instead of going all-electric because Dakar stages can be up to 500 miles long before detours and other unexpected events are factored in. Finding a charging station in the Saudi Arabian desert is easier said than done, and waiting for an electric car to charge isn’t ideal in a race where every split second is important. The system relies on a TFSI engine sourced from the firm’s now-shuttered DTM touring car program and set up to charge the 50-kilowatt-hour battery pack on-the-go. It operates between 4,500 and 6,000 rpm.
