History

In order to comply with the homologation regulations, the 924 Carrera GT and later 924 Carrera GTS were offered as road cars as well, producing 210 and 245 hp (157 and 183 kW) respectively. Clubsport versions of the GTS were also available with 280 hp (209 kW; 284 PS), and factory included Matter rollcage and race seats. 924 Carrera GT variations were known by model numbers 937 (left hand drive) and 938 (right hand drive).

The Carrera GTS was another racing car based on the Carrera GT and was developed in 1981 for private racing. As with the GTP and GTR, the engine was a turbocharged 2.0-liter four-cylinder. The compression was limited to 8.0: 1 and the boost pressure increased from 0.75 to 1.0 bar. This engine developed 180 kW (245 hp) at 6250 rpm.

The weight has been reduced by approx. 50 kg to 1121 kg compared to the GT. This was achieved by eliminating damping material, dispensing with comfortable interior fittings and using lightweight materials on the body. The interior was only covered with black needle felt and racing seats from the Porsche 935 were used instead of standard seats. Upon request, the vehicle could be delivered with a Carrera GT interior. The doors, the bonnet, the front apron and the flared fenders were made of light fiberglass-reinforced plastic. The pop-up headlights were replaced by built-in headlights that were protected by a plastic cover.

Optional comfort equipment was available. In this version, the doors with power windows as well as the sports seats and the center console including radio from the Carrera GT were installed. In total, the car was only ordered twice in this configuration.

The brake system and the wheels with rim dimensions 7J × 16 on the front and 8J × 16 on the rear axle came from the Porsche 911 Turbo .

Porsche also offered the car in a Clubsport version, which, at 1,060 kg, was around 60 kg lighter than the standard GTS. Modifications to the engine, such as For example, by increasing the boost pressure to around 1.1 bar, the output rose to 199 kW (270 hp). The vehicle was lowered at the factory and had aerodynamically designed sports exterior mirrors on the left and right. An aluminum roll cage was installed in the passenger compartment. Additional safety equipment included 6-point belts, a fire extinguisher and an emergency stop switch for the electrical system.

The total of 59 vehicles of the Porsche 924 Carrera GTS were produced exclusively in the color Indian red, 44 of which were delivered in the standard and 15 in the clubsport version. The car could be approved for road traffic via a TÜV individual approval in accordance with the StVZO.

The 924 Carrera GTS was built according to the specifications of Group 4 and could be used in rallies as well as in circuit races. Private teams drove the racing car in the sports car world championship, including in 1983 in the 1000 km race on the Nürburgring

In 1981 Walter Röhrl and his co-driver Christian Geistdörfer drove a Carrera GTS equipped for rally use in several rallies for the Monnet-Porsche team. In the German Rally Championship , the car made 2nd place at its premiere in the Metz Rally. In the following Hessen rally, Serengeti safari rally, Vorderpfalz rally and Sachs rally, they achieved victory with the 924.
