One of the more interesting but overlooked facts from the
2008 24 Hours of Le Mans was that the
Audi R10 TDI cars not only ran, but won, on a mixture of Shell V-Power Gas-To-Liquid (GTL) racing diesel and a newly designed Biomass-to-Diesel (BTL) fuel. We've been fascinated with prospects of biomass diesel since taking a trip to the Sears Tower in the
algae van, as BTL offers cleaner output, has no fossil-fuel base and doesn't interfere with the food chain. The version used in the race cars was also 90% cleaner than American low-sulfur diesel. We talked with Audi of America's Christian Bokich about his experience at
Le Mans with the winning diesel team.
