Three years after their triumph with a revised version of a Porsche 935, dubbed the K3, the Kremer brothers went about developing the CK5. The futuristic design featured a huge front-dipping windscreen and a fin that joined the closed cockpit to the back aerofoil, a prefiguration of the shark fin on all today’s LM P1 and LM P2 prototypes.
In 1982 the CK5 driven by Danny Ongais, Ted Field and Bill Whittington (who won Le Mans in 1979 with the 935 K3) was forced to retire. The following year RC Racing entered the chassis while the Kremer brothers divided their strengths. A new CK5 was handed over to Derek Warwick, Frank Jelinski and Patrick Gaillard while Philippe Alliot, Mario and Michael Andretti took possession of a Porsche 956. Both CK5s had to withdraw from the 1983 race, but the 956 which had dominated in 1982 came third overall.
The CK5 had a short lifespan, but the Kremer brothers returned to Le Mans 24 Hours in 1994 with a K8 prototype sporting Gulf’s emblematic blue and orange livery and finished sixth.
