Jaguar has unveiled its supercharged XKR coupe and convertible.


The aluminium monocoque body structure cars are powered by an uprated 420bhp supercharged V8 engine with six-speed automatic transmission and distinguished from the regular XK by a unique front bumper, aluminium-finish grilles and bonnet louvres; unique 19 and 20-inch alloy wheels and a quad-exhaust system.


Sales start in July.
