Read this today and found it very informative and begging some questions to be answered. As we well know the E-Trons (Eh trounced ) all the opposition at Le Mans (again) but there were other BIG names in there as well including Toyota and Honda with their own versions of GREEN. What matters to me is why cant F1 be as clever as 24hr series? they have much more advanced KERS type systems and of course 4WD. They even let the Delta Wing in there (for a while) which showcases the 24hrs as being way ahead of F1 in thinking future and technology. Please dont say that the price capping has prevented this - I doubt very much that providing 4 cars from Audi cost any more than it costs Mercedes to run Schuey and the Berg. Whats your feeling?

The permitting of four-wheel drive — another new opening Le Mans has recently explored — enabled Audi to combine the two technologies of 4WD and hybrid in an innovative drivetrain that, they say, has direct reference to future production line products. Indeed, they confirm: "The first experimental vehicles with the electric four-wheel drive e-tron quattro system are already being tested with a view to possible high volume production." The kinetic energy from the front axle during braking drives a motor generator unit that in turn accelerates a carbon-fibre flywheel, which runs in a vacuum. After the corner, when the driver accelerates again, the system delivers the energy to the front axle. The regulations allow 500 kJ of energy to be transferred to the front wheels between two braking phases, and the gears adapt the transmission ratio during acceleration and braking. At the back, meanwhile, an independent diesel V6 engine with 510hp powers the rear wheels - and the two independently powered front and rear axles are synchronized using electronic control, without driver intervention. As in F1, it's all about a compromise between weight, packaging, performance and regulation constraints — but Audi clearly made it work. And the fact they were allowed to could be a pointer to how future technology should be approached in Formula One.
