Audi RS6 beats Bentley Continental Supersports to get “fastest car on ice” title

Article by Christian Andrei, on March 9, 2011

With speeds of 206.05 mph (331.610 km/h), an Audi RS6 was named the "fastest car on ice” as it beat the record set by a Bentley Continental Supersport of 205.48 mph or 330.695 km/h (Bentley also introduced a limited edition called Supersports 'Ice Speed Record' Convertible at the Geneva Motor Show).

The Audi RS6 was put to the test at the makeshift track on the Gulf of Bothnia in Oulu, Finland. It can be recalled that when Bentley set the speed record last February, it was equipped with Pirelli SottoZero II tires on the Continental Supersports. However, Finland-based Nokian Tyres felt that they had to prove that their tires are better.

They didn’t want to just sit by while Bentley and Pirelli set this record on ice. Nokian also revealed that it used one of its own high speed test cars (which just happened to be an Audi RS6). Nokian emphasized that Audi did not participate in this attempt for a speed record in any way. Notably, there are no separate records for tires, cars or drivers etc.

The suspension of the Audi RS6 is laden with technology that ensures the car would be able to eke out a superb performance. For instance, its front axle features four lightweight aluminum control arms per wheel. Its elasto-kinematics has been developed to provide a sporty performance. Moreover, Audi retuned the attributes of the speed-dependent servotronic power steering, with the steering gear ratio tagged at a direct 12.5:1.

Audi also tweaked the kinematics of the rear suspension. Moreover, development engineers made use of Dynamic Ride Control (DRC), an exclusive damping technology that could reduce pitch and roll, employing only mechanical methods. DRC employs hydraulic lines and valves are linked to diagonally opposed pairs of shock absorbers. During cornering, there is a surge in the flow of fluid to the damper of the compressing outside front wheel, thereby augmenting support and reducing roll.

DRC, along with the sports suspension plus, provides three selectable damper settings accessible through the MMI. These settings include sport, dynamic and comfort. The new Audi RS6 is also equipped with the ESP electronic stabilization system that does not only allow for optimal driving enjoyment but also provides a high level of safety. It also features a relatively high activation limit that urges drivers to have a dynamic driving style.

Likewise, ESP features a Sport mode that can be completely deactivated. This new car from Audi rides on 19-inch alloy wheels wrapped in 255/40 tires, although clients may opt for the 9.5J x 20-inch wheels. The front axle features six-piston fixed black aluminum calipers – decorated with RS badges –as well as 390 mm brake disks. The rear axle, meanwhile, comes with single-piston floating brake calipers and 365 mm brake discs.

The rear floating steel disks are fitted with large cooling ducts as well as axial perforations, making them lighter yet better in terms of performance. When the 20-inch wheels are selected, customers may avail of a ceramic brake system that employs 420 mm and 356 mm discs on the front and rear, respectively. These discs are lighter than the steel disks by 12.2 kilograms (26.90 lb). The anthracite calipers - eight pistons on the front- are labeled "Audi ceramic."

The 4.93-meter (16.17 ft) Audi RS6 comes with a number of characteristic body features that allow it to stand out as a top-of-the-line model. These features include the single-frame grill, the headlights featuring xenon plus, adaptive light and Audi RS6-specific LED daytime running lights andthe air intakes, as well as the flared fenders and deep side skirts. Also included are the rear diffuser and the spoiler integrated into the trunk lid as well as the two large oval exhaust pipes.

Nokian Tyres Fastest on Ice: New World Record 331,61 km/h!

The new world record for fastest car on ice was set by Nokian Tyres' test driver Janne Laitinen who drove 331,610 km/h (206,05 mph) on the Gulf of Bothnia in Oulu, Finland. The record was broken on March 6th on a 14-kilometre ice track in freezing conditions. The world's leading winter tyre manufacturer equipped the record-breaking car with Nokian Hakkapeliitta 7 studded tyres (255/35R20 97 T XL).

Extreme speeds emphasise the role of top-quality tyres; they are the vehicle’s only contact point with the driving surface. When driving at exceptionally high speeds on slippery ice, the tyres must provide maximal grip, excellent structural durability and handling properties that are in line with the car's high power.

The acceleration formula is demanding. When a car moves at a speed of 331 km/h, the car covers over 92 metres in one second. The tyres are under immense pressure at these high speeds, and their diameter can increase by 15–20 mm. As the air resistance increases, more traction is needed in order to pick up speed.

- Testing at high speeds in demanding conditions forms an important part of our winter tyre development. Testing our boundaries can teach us new things, which can then be reflected in all of our products, explains Matti Morri, Nokian Tyres' Technical Customer Service Manager.

The Guinness World Records organisation outlines detailed rules for ice driving world records. The time for the one-kilometre distance is taken for driving in both directions of the track, and the world record time is the average of these two results. The vehicle takes a flying start. There is a total of one hour to complete the record attempt. The ice has to be natural and it may not be roughed up or treated with any chemicals. The tyres must be commercially available and approved for road traffic in the country in which the record attempt takes place.
