The Porsche Type 924 was originally developed as a joint venture/project between Volkswagen and Porsche despite some bumps in their 914 venture together. In the end Porsche bought the design back and built the 924 to be the company’s entry-level sports car (and replacement for the outgoing 914.) The Porsche 924 made its public debut in November, 1975. It was almost immediately criticized by enthusiasts for its mediocre performance. Over the years it was improved and in 1979 a 924 Turbo was released followed by 924 Carrera GT in 1980. The Carrera GT was really an evolution of the 924 Turbo model, but it was the 924 that Porsche had envisioned – namely one that was capable of competing on the world racing stage. The ultimate iteration of the 924 for the racetrack was the 924 Carrera GTR race car.
