Eight factory drivers will take turns in the car, which has two electric motors making the equivalent of 200 horsepower powering the front wheels in addition to the 448-horsepower 4.0-liter flat-six engine mounted in the rear. Astute observers will note that the engine makes less power than before (32 fewer horsepower than in 2010), due mainly to the organizers reining in the power.
The extra 200 ponies from the electric motors are available for a few seconds at a time, such as when passing. The car weighs about 20 percent less than it did in 2010, which could make up for the reduction in power. When the driver brakes, the electric flywheel accumulators that provide juice for the electric motors are recharged.
The idea behind the technology is that with less fuel consumption there will be less time-consuming pit stops.
If true, that could give Porsche an advantage over the 24 hours of the race. In racing, every little bit helps.
