In preparation for the renowned Le Mans 24 hour endurance race during the second weekend of June, Audi have shown their bio fuel R10 TDI title challengers.
Although made history by winning the 24 hour race previously with R10 TDI race cars, this year sees the use of special Shell V-Power diesel race fuel chemically processed from natural gas.
Cooking up 1 100Nm from wood?
Attempting to blend racing thrills and environmental responsibility might appear to be a contradiction in terms but a small amount of biofuel - extracted from foodstuff and wood bio waste - is to be mixed with the V-Power diesel.
This mixture promises a reduction in the emission of CO2 by nearly 90 per cent when compared with traditional diesel. The V12 TDI racing engines are 5.5-litre, twin-turbo V12 units producing 485kW and 1 100Nm.
"Audi voiced its support early for the use of next generation bio fuels at Le Mans," explains Michael Dick, Member of the Board of Management of AUDI AG with responsibility for Technical Development. "It underlines our philosophy that we view Le Mans as a tough test field for new technologies which will be available at a later date in production cars for our customers."
"The Automobile Club de l'Ouest (ACO) provides the opportunity to use alternative drive concepts and fuels, which we exploit to the full." The first public appearance follows this coming Sunday at the official test day at Le Mans. It traditionally provides teams with the only opportunity to test on the 13.629km circuit of Le Mans before the race.
