Hopefully EM will still be here when it's done (told you it was long term) and I can post some numbers. LoL
you can expect your fuel efficiency to be at 23mpg still ...

tahoe hybrid weighing in at 6500 pounds can do 85mph at 1800rpm (4 banger mode)barely get 26mpg..

it's in EVT mode when shifted to M4 it just the rpm to 2500 or so


6.0L engine LS2 based


at 30-40MPH she runs at 1,000 rpm..
45mph is 1050 rpm

at 40MPH steady you can expect to get about 40MPG in a 2600 pound car

I would expect the final numbers to be about 30City /40Highway

I suggest getting a hybrid V8 and disabling the AFM to use in it, the fuel efficiency will be in the 30-35 range.. even with it disabled
which is way better then the 5.3L which will be the mid to upper teens

It has way more power then a 5.3L engine (379HP/472ft combined output )

i don't think you will even need a drive shaft just connect the transmission output directly to the rear diff
