Porsche 904 GTS
Produced for just two years in 1964 and 1965, the Porsche 904 GTS was a racing car for the street. They designed it especially for the track but only homologated it as a road car. The flat-four engine was behind the driver and displaced 2.0-liters with a high output of 180 HP.
Since this was a racing car, the exhaust was uncorked, which provided the 904 with glorious noise.
