The Porsche 914-6 GT was a race car built by Porsche, based on the 914 model with a 6-cylinder engine and GT package. The 914-6 GT was a race configured version of the 914-6. The factory offered the GT option, which was distinguishable by its box-like steel fender flares. It quickly became known as the 914-6 GT and was raced employing different engine configurations. This included the 'T' specification, which was a basic 911 engine. Another popular configuration was to use a converted Carrera 6 engine.
Porsche only built 2 914/8s. The first was a development mule that Piëch used to prove the concept of a 914/8. The second was built for Ferry Porsche as a birthday present. Both are very unique 914s still owned by Porsche and regularly shown at the museum in Stuttgart. They had a 300 HP 3.0L 908 engine and a 916 transmission, and was never registered for the street. This was a test bed and a prototype.
Porsche produced two limited edition 914 models: the Creamsicle and Bumblebee, the latter created to celebrate the Porsche's domination of the Can-Am series with the Type 917. The Bumblebee was finished in black with contrasting Summer Yellow lower sections. Many otherwise optional items were standard on these limited edition models, including driving lights, dual horns, a leather covered steering wheel, and a centre console with clock etc. 500 of each type were manufactured.
After a highly modified 914 finished sixth overall at Le Mans in 1970, Ferdinand Piëch saw potential for a higher-performance, luxurious version that could be registered for highway use, and pursued the idea of what would become the Porsche 916. Planned for the 1972 model year, the Porsche 916 program was cancelled after eleven prototypes were built.
The Porsche Tapiro is a concept car built by Porsche in 1970. It was designed by Giorgetto Giugiaro and has a traditional 1970s wedge design, which critics say somewhat resembles the De Tomaso Mangusta. The chassis is based on the Porsche 914/6, and it features gullwing-style doors. First shown at the 1970 Turin Motor Show, it will be remembered as one of the most unusual Porsches and the first car to receive Italdesign’s signature wedge shape.
