This would make a lot of sense, IMO. I could drive an electric truck about 340 days a year. A range extender onboard for those other 25 days would be interesting.
Not sure why, it is the same powertrain as my 3.5EB, not detuned in any way, plus the added torque of the pancake motor added into the equation. Mine has only 420fp and the PB has 570fb, and my experience has been rather positive, starting with our old Carver. Bringing this thing back up over Jellico from Norris Lake made me a fanboi:
We have since downsized, this one is pretty easy:
I have not ever been towing a heavy racecar trailer every weekend or anything, but this has been the best tow vehicle I have ever had. Trying to switch to a van, but the Powerboost would be very tempting if it were available. Having the electric torque from a stop would be appealing.
