BMW M3 GTR E46
BMW wanted to battle Ferrari and Porsche in the American IMSA racing series. So for that purpose, they prepared the E46 M3. However, instead of a high revving 3.2-liter six-cylinder, their M Performance division installed a special 4.4-liter V8 engine that made the M3 unstoppable at the tracks. But, the other teams in the race series cried foul since the V8 wasn’t a production item in the M3 range.
So, BMW decided to create one of the craziest homologation specials ever, the M3 GTR. It delivered a whopping 493 HP with full racing equipment and an aero package. Interestingly, BMW built 10 cars, but never offered them for sale to the public. Apparently, all 10 are still in BMW’s ownership even though there were interested buyers willing to pay $220,000 apiece.
