One of the greatest supercars ever made. One of the greatest Porsches ever made. The Porsche Carrera GT.
When the Carrera GT was first shown as a concept car, it had a 5.5 liter V10 with 558 horsepower. This was a craziest thing Porsche could have dreamed up to make a concept car, except when they put the road version together it actually had a 612 horsepower 5.7 liter V10.
