The 2011 Le Mans 24 Hour regulations have been drawn up under the context of sustainable development and respect for the environment. The ACO and the motor industry have concentrated on two aspects that are crucially important from their point of view:


An endurance race like the Le Mans 24 Hours must enable entrants to test new technologies.
The focus of the Le Mans 24 Hours must be aimed even more strongly towards both the reduction of CO2 emissions and overall fuel consumption.
HYBRID SYSTEMS

The ACO wishes to give manufacturers the widest possible scope to use and develop such systems by putting a certain number of controls in place. Energy recovery systems will be allowed provided that they respect the following rules :


Recovery and release systems of energy at each axle (front or rear) to be a free choice.
Maximum quantity of energy released between two braking phases to be 500 kJ.
Energy storage: by electrical or mechanical systems.
Systems to be activated by the accelerator pedal only ('push to pass' buttons, e.g. KERS forbidden).
Hybrid safety specifications to be drawn up by the ACO.
Other means of energy recovery will be allowed: exhaust, engine heat, dampers, etc. provided that they respect the specifications drawn up by the ACO (safety considerations, banning of driver aids, evaluation of the increases provided by the systems, the reduction in fuel consumption and CO2 emissions).
Energy recovery systems using brakes must not be active during braking for curves (driver aids banned).
Fuel tank capacity reduction: 2 litres less for both petrol and diesel-engined cars.
Pit lane test obligatory for the cars in the hybrid category according to Article 1 / Definitions, Section 1.12 of the ACO LM P1 & LM P2 technical regulations, which stipulate that a car in this category must be able to cover the distance of the pit lane (400 metres) at a speed of 60 km/h using only the power generated by its hybrid system.
LM P1 & LM P2 PROTOTYPES

The new regulations follow the current evolution of the car in relation to the environment: namely, reduction in the power and overall performance of the engines.

2010 LM P1's eligible in 2011 provided that as announced two years ago, the cubic capacity of the LM P1 prototypes will be reduced. The 2011 regulations for the Le Mans 24 Hours, the ILMC, ALMS, LMS and the Asian Le Mans series have been revised to take into account the current economic situation and ensure a transition period. It gives the 2010 LM P1 prototypes an extra year with their performance adjusted in relation to the new 2011 cars. The development of the current chassis will be frozen as at 31/12/2010.

LM P2 "A Low Cost Formula" powered exclusively by production series engines with engine regulations close to those in LM GT2.
Capped costs: that of an engine must not exceed 75,000 , the sales price of a complete chassis with options without the engine will be 325,000 maximum - 400,000 for a complete car.
Minimum engine life: The life of an engine between two revisions will be 30 hours in 2011, 40 hours in 2012 and 50 hours in 2013.
The current LM P2s can still race in 2011 on 3 conditions :

1. Installation of a new engine derived from a production series.
2. Chassis development frozen as at 31/12/2010.
3. Performance adjusted in relation to the new 2011 models.
CREATION OF THE GT ENDURANCE CATEGORY

In 2011, there will be no LM GT1 category for the following three major reasons:


Numerous date clashes on the event calendars.
Very small fields outside the Le Mans 24 Hours.
The current category is entirely sprint based.
This is why in agreement with the GT manufacturers the ACO has decided to create a GT Endurance category with a single set of regulations valid between 2011 and 2013. These regulations are based on the current GT2 cars complying with the 2009 ACO rules with the following modifications:

Steering wheel mounted paddle gearshifts allowed.
Only 1 evolution per year allowed.
2 evolutions per year will be allowed for new cars.
Measures will be taken to reduce top speeds without reducing overall power.
The GT Endurance category will be for one type of car but divided into two classes from 2011:

GT Endurance PRO: a professional category, cars and drivers free.
GT Endurance AM: cars over one year old and with a minimum of two drivers classified in the bronze or silver categories (defined under LM P2 LMS 2010 regulations).
The Michelin Green X Challenge will continue in the PROTOTYPES and GT classes.
Reduction in tyre consumption (as defined in 2009 and 2010 ACO Regulations)
Reduction in noise level decibels (From 112DB in 2010 to 110DB in 2011)
PRE RACE PRACTICE DAY

The new regulations coming into force in 2011 will lead to the return of the test day in April or May. It will take place at least a month before the 79th Le Mans 24 Hours which will be held on June 11/12th.

I largely support the rules. I think the ditching of GT1 is absolutely fantastic, there is no need for two GT classes - and frankly there never has been. I also like the introduction of hybrid and energy recovery systems, the latter is a fantastic device of using unused energy to provide power. These eco-friendly technologies are mostly about image, and the concept of them is very simple and beneficial. Ferrari's road cars will have them soon with the 599 GTB, and so will Jaguar's - so they are relevant to future road cars.

One thing I think needs to be changed, is the limit in engine capacity for turbocharged petrol engines for the LMP1 class. If we are going to have a genuine fair chance for petrol engines, that are not limited - then turbo petrols should not be limited to four litres. Perhaps the ACO know that if a 5.5 turbo petrol was allowed, it would match or beat the current diesel engines.

i agree that hybrid (battery systems) are for eco weenies.

But the flybrid system seems different. With the porsche at the nurburgring running it getting 2 extra laps over most of the cars in it's class.
