The extra fuel it takes to get up a hill I typically save with a longer glide with the engine off on the other side, due to more momentum. Ultimately you only "lose" from slightly higher rolling resistance, and when you have to use friction braking and waste the larger momentum you've turned that gasoline into.

Sure, but if you can convert that weight disadvantage into some sort of power assistence while driving uphill and decrease the brake usage while downhill it might justify.

The energy required to drive the electric compressor is derived largely from recuperation under trialing throttle conditions, making it consumption neutral......

Weight transfers into momentum, which isn't a major loss when that momentum is recoverable energy via regenerative braking.

FWIW ,, on another forum that specializes in the LS grandchildren engines from GM, the FIRST mod on the newer ones is to disable the Variable displacement system. Its been tagged with serious engine wear issues (Again... Remember Northstar?) The un-powered cylinders wear out rings too fast.. And have piston scuffing issues.. For about 800 bucks HPtuner would let you play all you wanted with how it runs..

I wonder why that is? I would imagine those cylinders would still get lubricated, maybe they're just getting too cold?
