Background
Volkswagen's decision not to proceed with their designed-by-Porsche 914 replacement led to Porsche taking on the project themselves. Launched in November 1975, the 924 drew heavily on many contemporary VW Golf parts with an underlying Porsche design philosophy. Using Volkswagen/Audi components: the 924 was powered by a mild mannered 2-litre, overhead camshaft 2-litre, four-cylinder engine of Audi heritage (of the Audi 100's), and the four-speed transaxle was a VW unit. A road model with competition potential, the luxuriously equipped Carrera GT was launched at the 1979 Frankfurt Show. Easily distinguishable from lesser 924s by virtue of its bonnet air intake and widened wheel arches, the Carrera GT was built in limited numbers - only 406 were made - 400 cars being the minimum requirement to gain homologation for rallying and Group 4 events. The standard version came with 210bhp but this could be boosted to well over 300bhp for racing. Three cars were entered by the works in the 1980 Le Mans 24-Hour Race, finishing 6th, 12th and 13th.
The car's 2 + 2 packaging is clever, with an almost ideal 53% front/47% rear weight distribution, delivering extremely balanced handling. A five-speed Porsche-designed gearbox and improvements to the suspension were early developments, and in 1978 came the first truly high-performance 924 - the Turbo. The Turbo delivered an additional 45bhp which raised the top speed to around 150mph, and this would be further improved upon by the 924 Carrera GT. By February 1981, the 100,000th 924 left the factory and two more limited edition derivatives of the Carrera GT were offered. Produced for that season only, these were the GTS and GTR, the former being a 245bhp lightweight variant, although still road legal to comply with homologation regulations, while the latter was an even more powerful (375bhp+) competition car intended for racing and rallying. The 924 line was discontinued in 1988.
