Audi's motorsports techies, titans of the oil-burning racecar scene, say they want to run the R10 racer on biofuel at next year's 24 Hours of Le Mans. It's part of a companywide move, says Audi Sport's head of engine technology Ulrich "Torquenstein" Baretzky, to develop biofuel combustion technology for VW/Audi. But they won't be using leftover horse lard from the local bistros; they're planning to use Biomass to Liquid (BTL) fuel, or a synthetic derivative of plant-based oil, the producers of which are owned by team sponsor Shell. Oh, now we gets it.
