Kahn Design has come up with yet another upgrade package for the Range Rover, and this time the end result appears to be the ultimate in terms of luxury and performance. What we have here is Kahn’s brilliant RS600 kit fitted to a Range Rover 4.4 SDV8 Autobiography LWB. They call it simply the Performance Edition.

As with all the other Kahn Design Range Rover models, the Performance version looks absolutely superb, especially in this cool color called “Paris Grey” combined with the floating black roof, tinted windows, and blacked-out 9.5 x 23” RS wheels fitted with 305/30/23” tires.

The 16-piece styling kit on Kahn Design Range Rover RS600 package include a double vented front grille with 3D mesh, contrast roof in piano black, mirror caps in piano black, Kahn enamel wing shields, RS-600 front and rear wide wheel arches with integrated air dams, carbon side vents and a RS600 front chin spoiler.

As for the interior, this car gets perforated black leather, vented foot pedals in machined aluminium, door entry sill plates in stainless steel, centre console facia trim, steering wheel centre and Kahn branding. But as always you can customize every last detail.

The cost of Kahn RS600 Performance edition is £129, 875, which is not that bad considering it’s a highly exquisite tailored program.
