For me there's M division and there are other divisions, A motorsport car is not a simple update of a normal BMW with massive addition of uncontrolled power, no it's an M car, it is designed from the begining of developpement to be very sporty car with its specific engine, an ultra optimised chassis and a specific transmission and that's why M cars are so fatastic to drive, you don't need a looooooooong straight line to feel excitement, no an M car deliver pleasure in all type of roads and that's what make these cars ultimate driving machines.
