Some people would be satisfied with a vehicle as capable and luxurious as a Range Rover Sport. But that can't be everyone. Otherwise there wouldn't be companies like Project Kahn and Cosworth.

The two premier British tuning houses have taken the Range Rover Sport – the diesel model, not the supercharged V8 – and tweaked its engine to produce 500 horsepower, up from 313 stock. To go along with it, they've given the luxury SUV a thorough design upgrade including new bumpers, side skirts and wheels, plus an interior decked out in perforated and quilted leather with billet aluminum trim.
