How fast is your SUV on low friction surfaces?
Have you ever wondered how fast all those high-performance SUVs are on low friction surfaces? Yes, we all know they are fast on asphalt, but are they as quick on grass, gravel, snow or sand?
Judging by Land Rover’s latest performance test, the Range Rover Sport SVR, one of the most powerful models in this niche segment and the brand’s fastest vehicle currently in production, can handle all these terrains giving impressive acceleration figures. For example, “merging legendary all-terrain capability with 550-horsepower V8 power and advanced traction technology,” the SVR hits the 62 miles per hour (100 kilometers per hour) mark in only 5.5 seconds on sand and grass. It’s even faster on gravel at 5.3 seconds – pretty close to the 4.7 seconds the SUV is recording on dry asphalt. Standard Michelin 275/45 R21 All Season tires were used on all surfaces.
A snow test was also performed by the British manufacturer. To find enough snow the Range Rover Sport SVR headed to Jaguar Land Rover’s winter test facility in Arjeplog, Northern Sweden, where on a combination of snow and ice it completed the sprint in 11.3 seconds.
The vehicle was driven by Darren Jones, Stability Applications Leader at Jaguar Land Rover, who says “the Range Rover Sport SVR is famed for its on-road performance but this hasn’t been achieved at the expense of customary Land Rover capability. Our Terrain Response 2 technology takes the stress out of driving in all conditions.”
This is not the first case the SVR is tested on a snow, as in 2015, just a couple of months after its market launch, Land Rover took the sporty SUV for a test on an ice-carved replica of the Silverstone track near the Arctic Circle (video below). The vehicle is also the fastest SUV on the Nurburgring Nordschleife.

Whitley, UK, Monday 23 January 2017: Come rain or shine, grass or gravel, snow or sand, the Range Rover Sport SVR delivers devastating pace.
Merging legendary all-terrain capability with 550HP V8 power and advanced traction technology provides Land Rover’s fastest vehicle with unique real world performance.
Since going on sale in February 2015, the Range Rover Sport SVR has showcased the abilities of Jaguar Land Rover Special Vehicle Operations, with just shy of 1000 being delivered to customers in the UK. Many will have been attracted by the 0-60mph time of only 4.5 seconds, but the official figure only scratches the surface of the Range Rover Sport’s capability…
When the perfect traction offered by clean, dry Tarmac isn’t available, most sports cars immediately suffer from a lack of grip, stability and performance. But no sports car has the benefit of Land Rover’s legendary all-terrain know-how.
In this unique test, the Range Rover Sport SVR completes the 0-100km/h sprint on standard fit Michelin 275/45 R21 All Season Tyres on everything from tarmac and grass to snow and sand, using Land Rover’s innovative Terrain Response 2 technology.
The intelligent system automatically selects the appropriate driving mode to suit traction conditions including: General Driving, Dynamic, Grass/Gravel/Snow, Mud and Ruts, Sand, and Rock Crawl. The driver can also use a simple rotary controller on the centre console to choose a specific mode.
The times recorded are a testament to the Range Rover Sport’s inherent capability. On a notoriously slippery wet grass surface, the 0-100km/h time increased by only 0.8 seconds, while even on Sand the benchmark sprint took only 5.5 seconds.
|Grass||Grass, Gravel and Snow||5.5 seconds|
|Gravel||Grass, Gravel and Snow||5.3 seconds|
|Snow||Grass, Gravel and Snow||11.3 seconds|
|Mud||Mud and Ruts||6.5 seconds|
The ultimate all-terrain performance test in detail
The Range Rover Sport SVR’s first challenge was the start-finish straight at Europe’s fastest racing circuit, Rockingham Motor Speedway in Corby, UK. In Dynamic mode, Terrain Response 2 sharpens throttle response and changes gear at higher revs. It also stiffens the Continual Variable Damping function within the vehicle’s Anti-Roll Control technology to reduce body roll. With all of these factors optimised, the Range Rover Sport SVR blasted from 0-100km/h in 4.7 seconds.
In the second test, the high-performance SUV tackled one of the most challenging surfaces any driver will encounter: wet grass. In Grass/Gravel/Snow mode the throttle response is softened to prevent loss of traction and gear changes are smoother and quicker. The Traction Control System also intervenes earlier to prevent tyre slip, while the central differential is preloaded to optimise off-the-line performance. Land Rover Experience East of England provided the perfect setting for this challenge and the Range Rover Sport SVR recorded a breath-taking 0-100km/h time of 5.5 seconds.
A quarry provided the ideal gravel surface, where the Range Rover Sport SVR’s inherent traction came to the fore. With the vehicle systems optimised to suit the loose surface, it registered 5.3 seconds.
To find snow the Range Rover Sport SVR headed to Jaguar Land Rover’s winter test facility in Arjeplog, Northern Sweden. Here, the optimised settings and all-wheel drive system helped the SVR complete the sprint on a combination of snow and ice in 11.3 seconds.
The next switch of the Terrain Response 2 dial was to select Mud and Ruts mode. In this setting the air suspension is raised and the Traction Control System allows controlled tyre slip to provide better traction in slippery conditions. In typically British surroundings at one of Land Rover’s all-terrain testing facilities, the performance SUV logged a 0-100km/h time of 6.5 seconds as its intelligent four-wheel-drive technology came into its own.
Pendine Sands at Carmarthen Bay in South Wales has been linked with speed ever since hosting the first world land speed record run took place there in 1924. That made it perfect to test the next setting on the Terrain Response 2 dial: Sand.
Selecting Sand mode sharpens the vehicle’s accelerator responses to allow a quick build-up of engine torque. The vehicle also holds onto gears for longer and locks the central differential to help maintain momentum. The result of this technological wizardry was a 0-100km/h time of 5.5 seconds.
The final mode on the Terrain Response 2 dial called for something different. Rock Crawl is designed to assist drivers when negotiating rocky environments and works in conjunction with the Low Range transmission, in keeping with the low-speed nature of the challenge posed by large rocks and boulders.
Rock Crawl mode softens the accelerator response to mitigate against sudden movements and provide maximum driver control. It also raises the air suspension, to optimise ground clearance. Using Terrain Response 2 the Range Rover Sport SVR scaled the rocky 32 per cent incline at the test facility with ease.
