For testing purposes Porsche Motorsport built a few tarmac rally cars based on the Cayman 981 GT4 racing version. The Cayman rally car was the course car for the WRC (World Rally Championship) 2018 ADAC Rallye Deutschland. The FIA R-GT Cup was contested on tarmac rounds of the ERC and WRC, like the German WRC event.

For Porsche, the entry of a concept study based on the near-production GT circuit race car was a critical test under real conditions. “We’re looking forward to seeing how the rally world responds to our FIA R-GT concept study,” said Dr. Frank-Steffen Walliser, Vice President Motorsport and GT Cars.

Official Press Release

Demo run for the Porsche Cayman GT4 Rallye on snow and ice – 18/01/2019

The Zuffenhausen sports car manufacturer is planning a return to rallying. For this, the motorsport department in Weissach is developing the Porsche 718 Cayman GT4 Clubsport to comply with the FIA R-GT regulations. The vehicle should be ready to contest the 2020 season.

A decisive factor in this decision was the positive response at the launch of the Cayman GT4 Rallye Concept Car on the occasion of the 2018 ADAC Rallye Deutschland. Romain Dumas (France) drove the spectacular concept study as the course car. The first demo run on snow and ice for the rally concept vehicle will be at the Porsche Winter Event held before the GP Ice Race in Zell am See (Austria, 19/20 January). Piloting the concept car is local hero Richard Lietz, who currently ranks third in the FIA World Endurance Championship (FIA WEC, GTE-Pro).

In contrast to the concept vehicle, the future rally car will not be based on the Cayman GT4 Clubsport built up to 2018, but on the new 718 Cayman GT4 Clubsport unveiled in early January. The new customer sport racer, designed for GT4 series as well as clubsport and track day events, is powered by a 3.8-litre flat-six engine producing 313 kW (425 hp). In developing the vehicle, the focus was put on performance, driveability and sustainability. In the construction of the Porsche 718 Cayman GT4 Clubsport, several body parts were made of natural-fibre composite material for the first time.

The appearance of the Porsche Cayman GT4 Rallye Concept Car at the 2018 Rallye Deutschland yielded positive feedback. The response from the rally fan camp, teams, drivers and series organisers was a decisive factor in going ahead with the new development programme. The comparatively low operating cost of the new R-GT-regulation vehicle is a major advantage, thanks to its close affinity to the production car.

Porsche in rallying

Porsche has a long history of successes in rallying. Claiming overall victory at the Dakar Rally in 1986 with the Porsche 959 is regarded as a milestone. The Porsche 953, based on a four-wheel-drive version of the 911, also won the Dakar Rally. In the late sixties and early seventies, Vic Elford and Björn Waldegard celebrated major triumphs with the Porsche 911 at the legendary Monte Carlo Rally. In the recent past, many privateers have put their trust in various models of the Porsche 911 in national and international competitions. Moreover, Porsche’s works drivers Timo Bernhard and Romain Dumas have taken on private projects in rallying.

This is the FIA R-GT class

The R-GT regulations were introduced by FIA, the world’s governing motorsport body, for the 2011 season. The aim of the concept is to give ambitious customer teams and private drivers a chance to take on the sporting challenge of rallies in a cost effective way. For the 2014 season, the regulations were again extensively revised. Customers can contest events around the world with R-GT-homologated vehicles. Highlights include the famous Monte Carlo Rally and the legendary tarmac stages of the WRC round run on the Mediterranean island of Corsica.
