Project Kahn has announced their tuning package for Range Rover with 4.4 liter diesel engine. The program features both - a new styling and performance package.

Range Rover RS5 boats a new body kit consisting of a new bumpers (front and rear), modified side skirts and a new grille. The big SUV also has a four-tailpipe sport exhaust system and stands on huge 22" RSX alloys.

The interior features aluminum pedals, a revised instrument cluster, and stainless steel door sills. The luxury is at extremely high level - quilted leather upholstery, a sport steering wheel, and bespoke trim.

The performance package boosts the 4.4 liter V8 diesel to 500HP (373 kW). The company didn't release any further information about the tuning parts, but the result is staggering - an improvement of 191HP gain from the stock 309HP.
