A super lightweight Braille lithium ion battery provides power for the car’s electronics while weighing less than half of what a conventional battery does.  You can buy this for your own car as well!

Power is delivered from the engine to the Xtrac 6 speed sequential rear mounted transaxle via a Tilton carbon triple disc clutch and an aluminum driveshaft.  The transaxle uses Xtrac’s revolutionary low drag, low loss, limited slip differential.  We were not allowed to photograph any of this so a lot of this is actualy our educated guess.

Pratt and Miller would not let us get too close to the rear of the car but we were able to discern that it has an Xtrac six speed sequential transaxle.  A notable thing is that Xtrac has a low drag, low loss, limited slip differential.

The fact that the car does not use a conventional digital racing dash display tells us that the car probably runs on some bespoke electronics suite probably developed by Delco or another GM supplier as an engineering exercise.  The Grant steering wheel is not one you can buy from JC Whitney.  Look at the configuration buttons and the low tech hand drawn track map!

The car’s electronics look like some sort of bespoke stuff probably from Delco as we did not see too many familiar bits in the interior and the crew did not want to talk about any of it.  We did note that the car is air conditioned as per ALMS rules.  We think all race cars should have AC!

This centrifugal blower on the carbon duct is part of the super light, low loss, air conditioning system.  The AC system only uses 1.8 hp and is lighter than a cool suit.
