The Pikes Peak course starts at more than 9000ft above sea level, rising to more than 14,000ft at the finish. The 503bhp Supercharged Range Rover Sport had a roll cage and a multi-point harness for the driver fitted, but was otherwise standard showroom spec.
Dallenbach's time also eclipses Rod Millen's production car record, set in 1989 with a Mazda MX-6, by more than eight seconds - but that was set when the 156-corner course included loose dirt sections. It's now all-tarmac, so the two aren't really comparable.
Driver Dallenbach commented on June 6: 'There's no margin for error at Pikes Peak - you only need to misjudge one of those 156 turns and you're into the trees or over the edge of the mountain. To take on this place the way I did today, you need complete confidence in your vehicle, and the Range Rover Sport sure gave me that.'

Land Rover is planning a series of similar challenges for the Sport over the coming months, including wading through the Dead Sea, climbing into the Himalayas, and driving to the northern Pole of Cold. See: https://newrangeroversport.landrover.com/#challenge
