The 2015 Jaguar XK Coupe and Convertible retain much of the styling character dating back to the model’s last major redesign in 2007. Coupe and Convertible versions of the 2015 Jaguar XK are individually defined by three trim levels. A naturally aspirated 5-liter V-8 engine generating 385 horsepower powers the base model of the 2015 Jaguar XK in Coupe and Convertible. Standard features on the 2015 Jaguar XK Coupe and Convertible includes a heated and cooled leather seating, smart key system, Bowers & Wilkins 525-watt surround sound system, heated leather steering wheel as well as HID headlights. Providing 510 horsepower from a supercharged 5-liter V-8 engine, the 2015 Jaguar XKR is equipped with an electronic active differential, high performance braking and an Active Exhaust system. Adaptive Front Lighting System standard on the 2015 Jaguar XKR allows a headlight beam to be deflected up to 15 degrees for better illumination while cornering. Featuring carbon fiber aerodynamic pieces and a lowered suspension, the top-level 2015 XKR-S is tailored for high speeds. The supercharged V-8 engine’s output is bumped to 550 horsepower for the 2015 Jaguar XKR-S Coupe and Convertible.
