Purpose

I will try my best to provide detailed info on various cars and what is like to live with them, I have already produced a few for Jaguar-car-forums, I will do my best to be unbiased, but it will be hard for some cars. I will re-produce press releases and copy from other motoring news.

The Range Rover Sport SVR sets 0-100mph times on different surfaces.

  • All-Terrain acceleration test proves Land Rover’s capability and pace in all conditions
  • Range Rover Sport SVR verifies its super-SUV credentials setting 0-100km/h times on variety of low friction surfaces
  • Innovative Land Rover Terrain Response 2 technology maximises acceleration even on grass, gravel, snow or sand
  • Every sprint completed on standard Michelin 275/45 R21 All Season Tyres 
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.

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.
Driver Darren Jones, Stability Applications Leader, Jaguar Land Rover, said: “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.”

SEAT knows how to test its cars by making them go through a range of testing over 25,000km's, using 40 cars, 80 tests & 50 engineers.

  • 50 engineers, 80 tests, 25,000 kilometres driven and three weeks of work
  • All cars are tested in extreme conditions to verify their reliability in any circumstance; now it's the new SEAT Ateca's turn
A total of 50 engineers and 40 cars are ready to cover 25,000 kilometres and perform 80 tests in the desert region of southern Spain where daytime temperatures soar to 45°C in the shade. 
This is extreme summer testing, one of the world’s most demanding performance exams for cars, a genuine boot camp that lasts three weeks. Today it’s the SEAT Ateca’s turn, but what kind of extreme tests are a vehicle put through? Here are some examples.


  • Traction and controlled descent test. This tests the traction control systems on declines of up to 35% and how the Hill Descent Control performs; this system guarantees a controlled descent without the driver having to activate the brake pedal as well as the automatic enabling of the ABS system where necessary.
  • Towing control test. There is a greater risk of losing control of a vehicle when pulling a trailer. This test verifies the performance of the Trailer Stability Program, which is a system that helps the car remain stable when it has a hitched trailer.
  • Klapper test. A typical car has over 3,000 parts. This test ensures that all the components work in perfect harmony and do not cause any irritating noises for the passengers, no matter the type or condition of the surface being driven on.
  • Dust intake test. A lead car drives through the desert leaving a large dust cloud in its wake, immediately followed by the car being tested to determine the service life of the air filter.
  • Gravel test. The vehicles are driven 3,000 kilometres on a specific gravel course to analyse the impacts made by gravel on the entire undercarriage, wheel arches and the exterior and under surface of the bumpers. The goal is to ensure all the parts will resist during the vehicle’s service life. 
With nearly a month of trials and over 80 verifications behind them, the cars have been tested in all their possible configurations so that nothing is left to chance. Thanks to the extreme testing carried out by hundreds of engineers and technicians around the world, drivers can rest assured of being able to drive reliably on any road in the world. Next stop: winter testing.
SEAT is the only company that designs, develops, manufactures and markets cars in Spain. A member of the Volkswagen Group, the multinational has its headquarters in Martorell (Barcelona), exporting more than 80% of its vehicles, and is present in over 75 countries. In 2015, SEAT’s turnover amounted to over 8.3 billion euros, the highest in its history, and the company achieved worldwide sales of more than 400,000 units for the first time since 2007.
SEAT Group employs more than 14,000 professionals at its three production centres – Barcelona, El Prat de Llobregat and Martorell, where it manufactures the highly successful Ibiza and Leon. Additionally, the company produces the Ateca and the Toledo in the Czech Republic, the Alhambra in Portugal and the Mii in Slovakia. 
The multinational has a Technical Centre, which operates as a knowledge hub that brings together 1,000 engineers who are focussed on developing innovation for Spain’s largest industrial investor in R&D. SEAT already features the latest connectivity technology in its vehicle range and is currently engaged in the company’s global digitisation process to promote the mobility of the future.
