1989 Porsche 930 3.3 Turbo Cabriolet

Much of the Porsche 911's development had resulted from the factory's racing program, and it was the then FIA Group 4 homologation rules, which required 400 road cars to be built, which spurred the development of 'Project 930' - the legendary 911/930 Turbo. In production from April 1975, the Turbo married a KKK turbocharger to the 3.0-liter Carrera RSR engine, in road trim a combination that delivered 260bhp for a top speed of 155mph. But the Turbo wasn't just about top speed, it was also the best-equipped 911 and amazingly flexible - hence only four speeds in the gearbox - being capable of racing from a standstill to 100mph in 14 seconds.

The Turbo's characteristic flared wheelarches and 'tea tray' rear spoiler had already been seen on the Carrera model while the interior was the most luxurious yet seen in a 911, featuring leather upholstery, air conditioning and electric windows. For 1978 the Turbo's engine was enlarged to 3.3 liters, gaining an intercooler in the process; power increased to 300bhp and the top speed of what was the fastest-accelerating road car of its day went up to 160mph. Due to strong emission regulation in the US, the Turbo was not imported for the US market between 1979 and 1984, but retuned in 1985, now equipped with upgraded Motronic engine management systems. Targa and Cabriolet versions were also introduced.

The final production year of the legendary 930 Turbo was 1989, and these desirable end-of-the-line cars were fitted with the prized Getrag G50 five-speed transaxle, ensuring few cars would compete with the 930's unquestionable dominance on street and on the racetrack. More refined than hitherto yet retaining its high-performance edge, the Porsche 930 Turbo sold in the thousands, arguably becoming the definitive sports car of its age.
