Another car developed for Le Mans was the 1999 Mercedes-Benz CLR GT prototype, with a total height of just 1012 millimetres. Work on the design and construction of the vehicle, to meet the rigorous demands of the Le Mans 24-hour event, started in September 1998. The development objectives were aerodynamics for maximum speed with relatively low lift, the lowest possible weight, and optimum stability, to enable the car’s engineering to withstand constant maximum stress over a 24-hour period. The technology of the new car was based on the CLK-LM from the previous year. In spite of intensive preliminary trials, Mark Webber and Peter Drumbeck suffered accidents due to aerodynamic problems, and Mercedes-Benz pulled the third vehicle out of the race.
