Land Rover tease new Range Rover Sport R / RS – debuts at Goodwood (video)

The new 542bhp Range Rover Sport teased The idea of a more powerful Range Rover Sport – complete with the 542bhp version of the supercharged V8 from the Jaguar XJR and F-Type Coupe – has been around for quite some time, but it’s about to become a reality. Land Rover has revealed a teaser video for the new Sport R – which really shows no more than the spy video of the Sport R we had a year ago – but it does herald the imminent arrival of the new Sport R at the Goodwood Festival of Speed this month.

The unusual announcement--automakers typically don't comment on future-product programs--refutes reports about the Pagani C9's engine. In January, Road and Track magazine reported that the V12 for the C9 was derived from the V12 in the SL65 Black Series.
