During the 24h Le Mans 2012, the 2014 regulation has been revealed, set up with 12 manufacturers, it paves the way to more freedom, more electrification and especially more efficiency with an "energy allocation". Developments focused on an adaptability of the technologies for road use
Freedom: gasoline or diesel 4-stroke engines, free displacement, with a turbo pressure limited to 4 bars.
Electrification and efficiency: four categories of ERS from 2 to 8MJ (Energy Regeneration System) with different target values.
-Gasoline, from 4.8 to 4.42 liters of fuel per lap for consumption reductions ranging from 22 to 28% compared with 2011 vehicles, and a tank that decreases by 10.6l
-Diesel, from 3.93 to 3.56 l/lap, a consumption down by 25 to 32% and a tank containing 6.7l less.
Le Mans’ 2014 regulation is also open to other technologic options: 2nd generation biofuels (E20), but also at "medium to long-term" hydrogen or 100% electric.
Cost control is also on the table for more equity between the teams, with a limitation of the tests but also the number of engines and hybrid systems, private teams in turn can drive with non-hybrid vehicles.
From an aerodynamic standpoint, the vehicles will be shortened (from 1m90 to 2m this year), the pilot's position will be slightly higher while the cockpit will be completely closed, for a total weight of 850kg -excluding driver.
Le Mans asserts its position as a technological showcase for manufacturers by opening to alternative and hybrid energies, in the wake of the garage 56 with the Deltawing this year or the GreenGT in 2013.
