Audi has added a V-10 powered S8 to its lineup. The V-10 borrowed from the Gallardo pushes 450 horsepower and 398 lb.-ft. of torque through a six-speed transmission with paddle shift capability. The V-10 incorporates FSI direct injection technology borrowed from the R8 racecar. The new S8 rides lower than the other models and subtle badges distinguish it along with 20-inch tires and seven spoke wheels.
