The Audi R10 TDI is dead. Long live the R15. That's the moniker given to the next-generation Le Mans prototype set to wear the interlocking rings. The car will make its race debut in March at the 12 Hours of Sebring, and by the time the 24 Hours of Le Mans rolls around in June, Audi will have three of the cars ready to defend the trophy won by the R10 earlier this year. Details on the new car are very limited at the moment. All that's known is that it'll have a smaller, lighter, more efficient TDI motor, will once again be a roadster, and is a more significant change than Audi undertook when it went from the R8 to the R10.
The car will be publicly revealed closer to the Sebring race. According to the ALMS website, Audi Motorsport honcho Wolfgang Ullrich was quoted as saying, "It was clear to us that we must develop a new car if we wanted to continue to be successful in Le Mans." We read that as code for, "Those Peugeots were f**king fast this year. Here's our answer." By the time the cars hit the grid at Circuit de la Sarthe, the hype's going to be at a fever pitch. Bring it.







As is well known by now, Ford and Navistar have parted ways and the Blue Oval is developing diesel engines in-house to replace the PowerStroke lumps still being used. Slated to appear in Ford's trucks by 2011, the new oil burner code-named Scorpion is a 6.7-liter V8 with a host of innovations, some of them seemingly borrowed from cross-town rival GM. But the first thing you'll notice is that mammoth radiator. PickupTrucks.com estimates that the cooler up front is up to 20-percent larger than the one on the 2008 Super Duty, and that one had already been enlarged by 33-percent over its forebear. The extra cooling could be needed for "extreme towing applications", and if there's one truck that's an extreme tower, it's the F-Series Super Duty. The Scorpion diesel's innards will be enhanced with reversed intake and exhaust flow, something found on GM's Duramax diesel, and lighter aluminum cylinder heads. Nor will the Scorpion sacrifice mpg for its extra oomph: gains of 40 hp and 70 lb-ft will come with three more miles-per-gallon thanks in part to the truck's new 6-speed tranny that's debut as we speak on the new F-150.
