This video gives a bit of extra information about the hybrid system:
http://www.youtube.com/watch?v=VlSxA7z03Gw.
The front axle is driven by two 75 kW electric engines. This is exactly the same specification as the hybrid system of the Porsche 911 GT3 R Hybrid.
Dr. Ullrich explains that the complete hybrid system weighs around 80-90 kg.
According to
http://www.autosport.com/news/report.php/id/97739 the flywheel accumulator is supplied by Williams Hybrid Power. I agree that the flywheel seems a bit smaller than in the Porsche. However, the picture is only meant to illustrate the concept and it is probably not 100% accurate.
Judging from the picture the electric motors and power electronics are water cooled.
