here is the problem i see with the 5 series being a competitive formula d car.

it's way too heavy and way too predictable in its transitions because of its weight. a very light car like an s13 or corolla would be able to mime its' movements perfectly, while when following, the bmw woul dhave a difficult time following the line and quickness of transition that the lighter car can run.

other than that, it's big, its loud, it has four doors, and 6 cyls. that's bad ass!
