Le Mans 24 Hour Endurance Race.

At a time when Grand Prix racing was occurring throughout Europe, Le Mans was envisioned as a different test from motorsports at the time. Instead of focusing on the ability of a car company to build the fastest machines of the time, the 24 Hours of Le Mans would instead concentrate on the ability of manufacturers to build sporty yet reliable cars. This would drive innovation in not only reliable but also fuel-efficient vehicles, since the nature of endurance racing requires as little time to be spent in the pits as possible.
At the same time, due to the design of Le Mans, a drive would be created for better aerodynamics and stability of cars at high speeds. While this was shared with Grand Prix racing, few tracks in Europe featured straights the length of the Mulsanne. The fact that the road is public and therefore not maintained to the same quality as some permanent racing circuits also puts more of a strain on parts, causing more emphasis on reliability.
Beginning in the late 1970s, the demand for fuel economy from around the world led the race to adopt a fuel economy formula known as Group C in which competitors were given a set amount of fuel, from which they had to design an engine. Although Group C was abandoned when teams were able to master the fuel formulas, fuel economy would still be important to some teams as alternative fuel sources would appear in the early 21st century, attempting to overcome time spent during pit stops.
These technological innovations have had a trickle-down effect, with technology used at Le Mans finding its way into production cars several years later. This has also led to faster and more exotic supercars due to manufacturers wishing to develop faster road cars for the purposes of developing them into even faster GT cars.

The Results listed are for special interest and the only connection between Sports car and Formula One is drivers that took part as well as some Constructors who wanted to prove that the formula 1 Constructors can part take and win in an event dominated by Passenger car manufactures.

One extra point needed to be made in that Le Mans, Indianapolis 500 and the Formula 1 Drivers championship and to have at least won the Monaco Grand Prix, any Driver who can or has won the 3 most important motorsport events is considered the greatest Driver to ever be behind the steering wheel, yes there is many champions who have done brilliant at one class of racing, but to win these events and with totally different types of cars does deserve to be crowned a Triple Crown Winner Of Motorsport.
