For people who find the Range Rover just too self-effacing Project Kahn has announced two special versions of their own, following similar work on the Range Rover Sport. The RS300 uses a Cosworth-modified version of Land-Rover's TD V8 with 300bhp; while the RS600 is fitted with a tuned version of the supercharged 5.0-litre V8 developing 600bhp.

There are also the usual cosmetic modifications. Both versions come with 22-inch alloy wheels and pumped up body kits. The RS600 gets a 'wide-body' makeover with flared arches, sill extensions and spoilers.

The interior hasn't been left alone. Quilted leather covers the cabin. The front and rear seats carry Cosworth or RS600 logos - depending on version. On the dashboard the dials come with blue backgrounds.
