Porsche 993 Turbo 1996

993 was the last Porsche fitted with an air-cooled engine.

The 993 Turbo coupe was released in 1995. It featured a new turbocharged engine displacing 3.6 liters and producing 408 PS (300 kW; 402 hp). Twinturbochargers and air-to-air intercoolers, electronic engine management, redesigned cylinder heads and other modified engine internals were used. The 993 Turbo was the first Porsche Turbo with all wheel drive. The electronic engine management helped the Turbo to achieve fuel efficiency far superior to any of the previous production Turbos. In connection with two catalytic converters and an on-board-diagnostics-system including four oxygen-sensors, it also made the 993 Turbo the cleanest sports car at its time.

The Turbo's bodywork differs from the Carrera body by widened rear wheel arches (approximately 6 cm), redesigned front and rear bumper moldings, and a fixed rear wing housing the intercoolers. New 18-inch (460 mm) alloy wheels with weight-reducing hollow spokes were standard.

This was one of the first production cars in the world to have OBDII diagnostics (the 3.8-liter and track versions didn't have it, and the normally aspirated 993s didn't get it until 1996). All turbos since have had water-cooled heads. The car also had brakes that were larger than those on the base Carrera model.

Within the 1996 through 1998 production run, there were two distinct differences: the 1996 and the later ones. The 1997s and 1998s had the following differences from the 1996s:
