BMW M3 GTR

However, in the highly competitive world of motorsport, BMW needed a more efficient weapon against those Porsches and Ferraris in the IMSA championship of the early 2000s. So, BMW decided to create one of the craziest homologation specials ever: the M3 GTR. The M3 GTR came with 493 HP, full racing equipment, and an aero package. Interestingly, BMW built ten cars but never sold them to the public.
