All-electric SUVs are gaining popularity, from the Tesla Model X and Rivian R1T to the Jaguar I-Pace and Audi E-Tron. But none of those are quite like this.

Feast your eyes on the Odyssey 21, the backbone of the upcoming Extreme E championship. The off-road racing series is set to kick off in 2021 as sort of an off-the-beaten-path alternative to Formula E (and organized by some of the same people). And it just ran its new all-electric rally machine up the hill at the Goodwood Festival of Speed this weekend to the delight of the gathered crowds.

The Extreme E-SUV Odyssey 21 is being developed by Spark Racing Technology, the same outfit – founded by Sauber F1 team principal Frederic Vasseur – that made the single-seat/open-cockpit chassis for the Formula E series, with batteries furnished by Williams Advanced Engineering.

Full specifications have yet to be revealed, but Autocar reports that the vehicles will pack 542 horsepower's worth of electric power, propelling the 3,638-pound vehicles with their nionium-reinforced steel tubular frames, to 62 in 4.5 seconds, while climbing gradients up to 130%. That's 52 degrees, or slightly more vertical than it is horizontal, riding on 37-inch off-road tires supplied by Continental.

Instead of stadiums or rally stages, the Extreme E series is set to race in remote locations around the world – from frozen glaciers to desert sands – sailing between locations aboard an oceanic exploration vessel.

"The Extreme E-SUV ODYSSEY 21 is unlike anything else in motorsport," said Formula E chief Alejandro Agag. "Whether it's in the Arctic, Himalayas, Amazon, Sahara or on Indian Ocean Islands, this car will showcase the ability of E-SUVs, not only to motorsports enthusiasts, but also to consumers who are looking to make their own difference to the planet by choosing an electric SUV."
