Range Rover Sport tackles ski course with 75-percent grade [Video]

The Inferno Mürren downhill course descends for 7,119 feet and twists for more than nine miles.

Land Rover has released a video showing the Range Rover Sport tackling the legendary Inferno Mürren downhill ski course in Switzerland.

The 9.25-mile route required driver Ben Collins to navigate a 7,119-foot descent with steep grades of up to 75 percent across a mix of snow, ice, scree, mud, rock, asphalt, gravel and grass.

"The route was insane and certainly the toughest course I've ever completed," said Collins. "It challenged you with every kind of obstacle this side of molten lava and as conditions go, it was about as bad as it gets - torrential weather mixed with cliffs, trees, all kinds of stuff you don't really want to crash into."

The former 'Stig' reached speeds of 75 mph at the top of the course despite ice and sleet, while wet grass across the bottom section did not prevent him from bringing the Range Rover Sport up to 96 mph.

The stunt adds to a history of Range Rover Sport achievements including a record-setting Pikes Peak run and a record crossing of the 'Empty Quarter' desert in the Arabian Peninsula.
