November 26, 1963 – Porsche debuts the 904 Carrera GTS

After withdrawing from Formula One at the end of the 1962 season, Porsche refocused its attention to sports cars, where the company originally made a name for itself. Still wanting to compete on the track, they looked to dominate the FIA-GT sports car class. To do so, engineers developed the mid-engine Porsche 904, which debuted on this day in 1963. It is officially called the Carerra GTS due to a naming rights issue, similar to why the Porsche 901 became the Porsche 911.

The 904 became Porsche’s first vehicle to use a ladder chassis and a fiberglass body. Its engine was inherited from its predecessor, the 718, which was the factory’s leading race car at the time. The 1,966 cc, four-cam flat four made 180 hp and pushed the car to 160 miles per hour when red lined in fifth gear.

The car made its racing debut at Sebring in 1964 where it suffered clutch trouble. Its problems would be resolved and it would go on to see some wonderful finishes. It took first over all at that years Targa Florio, third at Nurburgring and five of six cars entered in the 24 Hours of Le Mans finished in overall positions seven, eight, ten, eleven and twelve. In that same race, a 904 set a 2-liter lap record and won its class. Production of the Porsche

904 ended in 1965 and was succeeded by the Porsche 906. Only 50 examples of the 906 ended up being built.
