This weekend's round of the American Le Mans Series at Miller Motorsports park in Utah will see the four Ferrari F430 GTs of Extreme Speed Motorsports and Risi Racing switch from running on an E10 ethanol/gasoline blend to using cellulosic E85. With this change, 10 of the 13 cars running in GT2 will be using the second-generation biofuel. The Corvette Racing team was the first to use E85 in early 2008 and since then the Flying Lizard Porsches and Rahal Letterman BMW M3s have also made the switch.

The Ferrari factory developed the updates to the fuel system and the calibration to allow the cars to run on alcohol. Running on E85 is expected to help improve the performance thanks to the increased octane rating of the fuel.

Biofuel now powering 10 of 13 GT entries this weekend at Utah


The alternative energy revolution continues in the American Le Mans Series presented by Tequila Patrón. Extreme Speed Motorsports became the latest team to switch to cellulosic E85R for the 2010 season; both its Ferrari F430 GTs will compete for the first time on the energy source at this weekend's Larry H. Miller Dealerships Utah Grand Prix.

Risi Competizione's two Ferraris also will compete for the first time on the biofuel this weekend.

"It's mostly a development by Ferrari to improve the performance of the cars," said Derek Granison, ESM's team manager. "And everyone in the paddock wants to go green as well. "We're still looking over the data from the test earlier this week and compiling information. Generally, it has shown to be improvement that needed to be made."

Ten of the 13 cars in the GT class will be powered by cellulosic E85 - Corvette Racing, BMW Rahal Letterman Racing Team and Flying Lizard Motorsports (all two-car efforts) are the others; Drayson Racing, Autocon Motorsports and Intersport Racing are all on the biofuel from the prototype ranks. In addition, Dyson Racing's Mazda-powered Lola coupe uses isobutanol.
