The family resemblance to the normal XKR is certainly present, and that’s because the RSR XKR GT shares more with the road-going car than you might imagine. No silhouette racer, the XKR GT boasts both the stock XKR’s aluminum monocoque structure but also a version of the “AJ” type Jaguar V8 engine, in this application producing more than 500 horsepower. Of course, it wouldn’t be a competitive GT car without some race-only modifications, such as the transmission, lightweight multispoke alloy wheels, and massive multi-piston brake calipers front and rear. Keeping the rear end planted is a massive rear wing, and lower body aerodynamics also help manage airflow and downforce. And with Jaguar’s leaping cat gracing the side of the XKR GT, there’s no mistaking which company produced this gorgeous coupe.
