The Porsche 906 or Carrera 6 is a street-legal racing car from Porsche. It was announced in January 1966 and 50 examples were subsequently produced, thus meeting the homologation requirements of the FIA's new Group 4 Sports Car category to the number. The type would also compete in modified form in the Group 6 Sports Prototype class.

Prior to the Porsche 906 was the 904 which held many racing victories. At the age of 28, Ferdinand Piëch, the grandson of Ferdinand Porsche was given the important job of being in charge of the development of the new Porsche racing cars. His goal for recreating the 904 to the new 906 was to make it as lightweight as can be. This would mean stripping all of heavy steel from the body and using unstressed fiberglass instead. Constructing the new car with the fiberglass helped with things such as structural support as well as looks because it was all placed by hand instead of having an uneven paint job done to it.

The finished product weighed around 580 kg (1,280 lbs) and was around 250 lbs lighter than the previous 904. Not only was the body of the car much lighter but so was the engine of the vehicle. Normally the car would be fitted with a 901/20 6-cylinder with carburetors that was making 210 horsepower at 8,000 rpm. On occasion though there would be times when it was replaced with a 8-cylinder when the car was being used by the factory racing team. This would help in events such as hillclimbing when the altitude would increase against the Ferrari Dinos in the European championship.
