As good as the cars wearing the prancing horse and the raging bull are, for the true driving enthusiast, there’s really only one contender – the Ultima RS. Founded in 1992, Ultima Sports has been making street-legal race cars that are among the highest-performing autos ever made. The Ultima RS modifies the Ultima chassis to accept all current Chevrolet LT V8 engines. From the base 450 horsepower LT to the supercharged motor current Corvette ZR1, the classic combination of American power and British chassis makes the RS a formidable competitor. For the truly insane, a 1,200 horsepower supercharged V8 is also available, making the RS a Le Mans racer for the street.
