They had to do something. The vette is any other fast American car... Mustang, Camaro, Challenger.... Goes real fast as long as it's in a straight line. Toss it on a track, and all that horsepower gets left behind by "lesser" cars that were much better designed. Smaller motors that made more power, suspension meant for non-grid roadways. Wouldn't feel too bad. Lamborghini has also been left in the past. They put emphasis on track cars like Corvette, and consumer models are snipped at the balls before hitting the showroom floor.
