Peugeot Sport used the final round of the 2008 Le Mans Series at Silverstone to unveil a hybrid 908 HDi FAP equipped with a kinetic energy recovery system (KERS). The 908 HY will provide a preview of what Peugeot’s next endurance racing challenger could resemble, although its use will depend on the regulations that will govern LMP1 cars from 2009.
The 908 HDi is based on a 5.5-liter V12 diesel engine that produces more 515 kW (700 bhp) of power and a torque output greater than 1,200 Nm. The 908 HDi FAP made its race debut in 2007. The hybrid system featured on the 908 HY demonstrator comprises three key elements:
A 60 kW gear-driven electric motor-generator which takes the place of the conventional starter motor;
600 lithium-ion cells divided into 10 battery packs (six in the cockpit instead of the conventional battery and four on the left-hand side of the flat bottom); and
An electronic power converter (located in the rear part of the front left wing) which controls the flow of energy between the batteries and the motor-generator.
The 908 HY can be powered in one of three ways: electric mode only (e.g. in the pit-lane); internal combustion engine only; or a combination of the two.
In the course of a lap of Le Mans, for example, the system will recuperate energy for between 20 and 30 seconds. This energy can be used:
Either to deliver extra power thanks to an additional boost of 60 kW (80 hp) for approximately 20 seconds per lap, either automatically when re-accelerating, or when the driver chooses to make use of it (“push to pass”); or.
To reduce fuel consumption for the equivalent level of performance thanks to the mechanical energy recovered (between 3-5%).
This hybrid 908 HDi FAP is in perfect keeping with the overall mission of our endurance racing program which covers not only the challenge of competing, of course, but also the fact that as a car manufacturer we can use motor sport as a research and development tool for the Peugeot brand as a whole. After innovating through the use of our HDi FAP technology in competition, running a hybrid car in endurance racing would give Peugeot a chance to gain extremely valuable experience that would benefit the development of production cars. Whether we use this technology or not in 2009 will obviously depend on the details of the new regulations published by the Automobile Club de l’Ouest.

Next they will have a 500 kW motor and replaceable battery pack to make car racing even more exciting.
I hope.

That would be as exciting as R/C car racing.

They should used the steam engine from Cyclone Power Technology.
There Mark IV engine can deliver 330hp and 2310ft/lbs from 0 RPM. If you scale up the engine up to much the power, the car will fly with such torque.

the diesels in american lemans have incredible mileage allowing them one or two less pit stops, add the energy recovery and they probably wouldnt need any pit stops anymore. Eliminating a pit stop or two is a tremendous advantage.

For track racing with short straights (ie with lots of braking and accelerations), hybrids are very suitable, especialy those with AWD and all-wheel braking to recouper most of the energy.
Battery swapping doesn't seem to be a good choice for racing cars as batteries will often be placed at multiple locations, very low, as ballast for best weight distribution, usualy making them difficult to access and replace quickly during pit stops.
For endurance track racing with lots of braking, series hybrids (AWD, possibly in-wheel motors) with diesel or HCCI engine gensets (operating at optimal, fixed rpm) seem to require the fewest Nr of pit stops (assuming the sufficient battery energy density), offering distinct advantage over other configurations.
Fifty thousand dollars more or less for a racing car is not an issue, it's usually less than 10% of the vehicle cost.
In a couple of years there may be such a car at the race 24 hr of Le Mans, in 10 years they may all be like that (series hybrid HCCI/diesel, AWD).

Please review our energy recovery system we can reduce the weigth of your system and more. William
