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.
