Okay, so yeah, yeah, this is basically Audi blowing smoke up the asses of themselves and their suppliers in the R10 project, but it's also pretty interesting if you're interested in prototype racing. One of the interesting things is that the R10 features particulate filters and uses GTL diesel fuel, which makes it a pretty damn clean diesel. We know that it turns out 650hp and 1,110 newton-meters of torque, but we'd love to know just how many lb. ft. the thing makes, since newton-meters and foot-pounds don't exactly translate directly a newton's a measurement of energy and a pound's a measurement of weight. [UPDATE: Surprise, surprise, Audi just took the pole at Sebring. Thanks, John.]
