Yes, a chassis that was last competitive in the early 1990s will form the basis of a modern—and, as the team hopes, competitive—rallycross car. It’s an unconventional but extremely cool approach.
From what we can gather, it’s no silhouette racer, either. GCK describes it as a retrofit of a Delta Integrale using its Exclusiv-e retrofit package, so it seems that a donor Evo must disgorge its internal combustion engine and go electric. The EV powertrain is provided by Kriesel Electric (which supplies all the powertrains for the class), and is claimed to produce 671 horsepower and 649 lb-ft of torque.
GCK has a history of fielding various Renault models in past Rallycross championships, and also supplies power to the FIA RX2e championship and the newly all-electric Rallycross Championship for 2022 (following up on the Projekt E support series, too). Other entrants are based on the things you’d expect—Euro hatchbacks from Skoda, Ford, and the like—but given its absolutely legendary Lancia basis, the GCK will likely be a fan favorite.
