24h Le Mans
From windscreen wipers to disc brakes and the turbocharger, many innovations have proven themselves in the greatest endurance race in the world. With the emergence of hybrid powertrains, the twice-around-the-clock event is more perfoming its role as a racing laboratory more than ever.
The LM P1 class (Le Mans Prototype 1) welcomes machines at the leading edge of progress. All ideas are welcome: front or rear engines, petrol or diesel, turbocharged or atmospheric ... But the big trend right now is the emergence of systems for kinetic energy recovery (KERS). Storage batteries or flywheel, returns energy to front or rear wheels.
To be considered as a hybrid, an LM P1 must be able to move the entire length of pit lane at 60 km/h using only its KERS. When the car is running on the circuit, the amount of energy delivered between two braking zones should not be greater than 500 kilojoules (approximately 100 horsepower for 6 seconds).
In theory, the winner of the 24 Hours of Le Mans would be in the LM P1 class. Audi and Toyota are the favourites, but Honda, Oak, Pescarolo and Lola will waiting to take advantage should the leaders run into trouble.
