Because of the relative success of the 924, Porsche decided not to scrap the design and use it instead as a basis from which to develop a replacement front-engine, rear-wheel sports car for both the 924 and 928. Porsche re-worked the 924 platform and developed an all-new, all-alloy 2.5 liter, inline-four cylinder engine to power this new model, which had been dubbed Type 944. Porsche introduced the 944 as a production vehicle in 1982. In its first iteration, the car offered drivers better handling and stopping power, and was considered far more comfortable to drive. The Porsche 944 Turbo was introduced in 1985 and featured a turbocharged and intercooled version of the base 944’s engine as well as better aerodynamics, strengthened gearbox, external oil coolers and more. In 1987, Porsche introduced the Porsche 944 S which featured a high-performance, naturally aspirated, dual-overhead-cam 16-valve version of Porsche’s 2.5 L engine. In 1988, Porsche introduced an even more powerful variant to the 944 lineup – the Porsche 944 Turbo S. In 1989, Porsche also introduced the 944 S2 Cabriolet, the first of the 944 series of cars to feature a collapsible (convertible) roof.
