R10

This is it! The grand finale. The last race of the 2007 American Le Mans Series. Smells from smoking tires and glowing-red brakes fill the afternoon air of the undulating rolling hills of Monterey, California. LMP2 Acura ARX-01, GT2 Ferrari F430 GT, LMP2 Porsche GT3 RS Spyder, and GT1 Corvette C6.R burble thunderously as they brake and downshift in a packed formation to make turn four near the Yokohama foot-bridge at Laguna Seca raceway. In the middle of this pack is the mysteriously quiet Audi R10. The only thing I can hear from this engineering masterpiece is the whizzing noise of the cross-drilled carbon disc brake and occasionally the soft burble of the 650 hp 811 ft-lb V12 TDI engine.
