Unveiled on the eve of Concours d’Elegance, Jaguar unveiled the XKR 175 ($104,500), a limited edition car that celebrates the 75th birthday of the famed prancing feline. The newly performance-tuned XK will feature a supercharged 510 hp V8 which will hit a top speed (electronically limited) of 174 mph. To keep the ride as smooth as possible Jaguar retooled the aerodynamics to include a new front air dam, side sills, rear diffuser, and a large rear spoiler. And if you think you’re suffering from Deja Vu, you’re not. The car is the American complement to the European “XKR 75”, of which the American model will be limited to 175 editions.
