My question to this is...How does one figure a drivetrain loss of 12% of the Hellcat and 10% of the ZL1? They both have superchargers and lots of damn accessory drives. Is it the transmission? Btw, did GM overrate the ZL1's numbers or is somebody getting this all wrong?
Drivetrain loss is everything behind the crank.

Transmission, drive shaft, rear end, axles, tires. The bigger and beefier they are, the more power they take to turn.

The ZL1 is SAE certified so it's not over or under rated. Same with the hellcat. They only allow a 1% deviation to get that certification.
