Land Rover wondered about this and decided to pit the Range Rover Sport SVR on various terrains to see how fast it could hit 100 kph (62 mph). The automaker released a video showing an SVR driving on tarmac, grass, a muddy trail, gravel, and snow. Not only was this a demonstration of the 550 horsepower supercharged V8, but it was also a demonstration of Terrain Response 2 system which was able to put the power down on various surfaces. It should be noted the runs were done with the SVR's standard tires, a set of Michelin all-seasons.
We'll spoil one part of the video. On tarmac, the Range Rover Sport SVR hit 62 mph in 4.7 seconds. If you want to find out how it fared on the rest of the surfaces, you're going to need to watch the video.
