Volkswagen is launching a one-make Bio-CNG-powered race series in 2010, and the company claims this fuel reduces CO2 by 80 per cent.
This follows the successful debut of the compressed natural gas-powered Scirocco GT24-CNG at the Nürburgring 24-hour race.
The Scirocco Cup aims to demonstrate that major innovative strides are still being made in motorsport, and Volkswagen believes it will be the most eco-friendly one-make championship in the world.
The Cup version of the Scirocco is designed to enable eco-friendly motorsport. Based on the TSI unit fitted in the Scirocco, the Bio-CNG-racing version of the 2.0-litre four-cylinder engine develops 203 lbs ft of torque and up to 223 PS. A push-to-pass system provides a short burst of increased power of 30 PS to create additional overtaking opportunities and action throughout the race.
Steering wheel-mounted paddle shifts operate a six-speed DSG gearbox and, as with the road-going Scirocco R, power is channelled through the front wheels.
Fitted with a fuel tank with a capacity of 22-litres, the Volkswagen Scirocco Cup uses so-called Bio-CNG which is produced from renewable resources such as grass or a special type of maize as well as from refined biological waste. The fuel tank itself is made from a composite material and is located behind the driver’s seat, protected by the vehicle’s roll cage.
The stainless steel pipes and special valves required for CNG operation within the Scirocco Cup use tried and tested components from Volkswagen production models with CNG engines, and the system pressures of 200 Bar are identical to those of the production vehicles.
Commenting on the new Scirocco Cup, Volkswagen Motorsport Director Kris Nissen explained: ‘By clinching class victory at the Nürburgring we proved that CNG-powered vehicles not only deliver high fuel economy but also allow very sporty driving. That’s why we’re particularly proud about launching the world’s first one-make cup with CNG-powered vehicles.’
