It seems like only last year that German tuning house Arden released a kit for the Range Rover Sport. Back then, the numbers were impressive (480hp and 472 lbs-ft). But nowadays we hit the snooze button for anything with less than 500 ponies. So Arden went back to Untergath and returned with the AR6, a Range Rover Sport tuner that produces 520 hp and 502 lbs-ft of torque via a blower kit and stainless-steel sport exhaust. It also comes with beefed-up brakes, a body kit only a footballer could love, 22" wheels and the stance of a sumo. We suppose that's more like it.
