Audi R10 TDI

Automotive enthusiasts (racing fans in particular) and environmental lobbyists don't always see eye-to-eye. Make that seldom, if ever. But greener motorsports is something over which we can definitely sit down with our compatriots at sister site AutoblogGreen. In fact, we'd go as far to say that it's the one thing that could stand to keep automobile racing relevant in the modern era, and we'll applaud any series, team or supplier that moves the cause forward.

Audi, then, is a particular favorite, for their milestone achievement of fielding the diesel-powered R10 in endurance racing series and events – and winning, sweeping the field, in fact, despite the self-imposed oil-burning handicap. But the boys at Ingolstadt aren't about the rest on their proverbial laurels, they're pushing forward, together with their sponsors over at Shell. They've announced that at next year's 24 Hours of Le Mans, they'll not only be racing on diesel, they'll be racing on biodiesel! Don't expect to see Audi engineers rummaging through the trash bins behind the local greasy-spoon, though. Audi will be using a synthetic derivative of plant-based oil (though we have no idea how something synthetic can be derived from something natural) produced by a subsidiary of team sponsor Shell.

Now that the announcement has been made, it seems such an obvious move, but then, all great developments seem so simple once they're done. Our hats go off to Audi and Shell for this, and we'll be looking forward to Le Mans next year.
