The DPs I think just ended up being fillers that Doran brought along with their 370s and wrapped for the commercial.

Amazingly, these rear wheels are powered. Spot the driveshaft.

This seating position blows my mind too.

Super cool. Looking forward to seeing it on track.

Thanks for the pic showing the rear driveshaft, wonder how they get drive to them? I wonder if they considered chain drive to the rear wheels like the old Honda S500?

It sounds like the drivers' legs are raised in part to allow space for the huge flywheel that's used to store power for the hybrid system underneath them.

There is a vertical gearbox with reduction gearing in each rear wheel hub. The halfshafts are in the top of the bodywork.

I was under the impression the rears were driven by the Hybrid system only, the ICE was only capable of driving the front wheels? Also only five gears? Some LMP machines are six or seven?

The Audi R10 was originally a five speed. I believe all other current LMP1s are six speeds.

And the ICE is only currently running the front wheels but could run all four if Nissan decides to go that way. The flywheels are connected to the front gearbox through a driveshaft running through the V angle of the ICE, then back out to the rear wheels.
