MotoGP and the American Le Mans Series. ALMS probably has the best racing of any series in my opinion. In addition to having multiple classes on the track at the same time, the GT field is insanely competitive. This year its going to be made up of Corvette, Ferrari, Porsche, BMW, Ford, Jaguar, Aston Martin, Lamborghini, and maybe Panoz. The first four are always fighting it out for the class win, the Ford GT’s, while usually slow, look great, the Jaguar is entertaining in its own way (never making more than 2 or 3 laps), and Aston and Lamborghini are new elements this year.
