Porsche 968 Coupe (1992 - 1995)
The Porsche 968 was a new-and-improved version of the Porsche 944. The 968 also came with an upgraded engine, an improvement on the 2.7L M44/12 16-valve inline-four cylinder engine found in the last base Porsche 944 model from 1989. The new engine now has a 3.0L capacity and makes 237 horsepower, a 64HP upgrade from the 2.7L model. In addition to the engine, the 968 also came with a new transmission. The 944 has a 3-speed automatic or a 5-speed manual transmission.
The new Porsche 911 GT3 Cup is powered by a 3.8-litre six-cylinder flat engine. It generates 460 hp (338 kW) at 7,500 revs, surpassing the predecessor by 10 hp. A six-speed dog-type gearbox developed by Porsche Motorsport which is operated via shift paddles at the steering wheel for the first time in a Porsche brand trophy race car transmits the power to the rear axle. The single piece race wheels with centre mount were also new.
As the rules do not permit higher output engines, the engine for the 991 RSR was taken from the 997 GT3 RSR 4.0 and the development work focused on the chassis, body, aerodynamics and the gearbox. A wishbone front suspension replaced the McPherson struts used in 997. A new development was the lightweight gearbox. One of the priorities in the development was the more evenly balanced weight distribution. The centre of gravity was lower, too.
