It will all depend on the type of driving and charging you’re doing. If you fill up, run on pure electric until it’s depleted then all gas without charging, I suspect you will get around the 370 estimated range. If you fill up and jump on the highway for 500 straight miles, I don’t know.... I would like to know the answer to that as well, since it seems there must be some regen happening while cruising. Now if you’re doing a mix of short and long driving while charging at night you can likely go much farther than 400 miles on a tank. Theoretically it’s unlimited if you only use electric then charge every night. However we know the reality will be somewhere between the two ends of the spectrum.Can it still go 400 miles in one tank?
For me, I expect to get much more than 400 per tank as plenty of my driving will be day trips and recharge at night. When I take a road trip to Moab I won’t expect the same level of efficiency and will probably even save the electric power for when I get there and want the added HP and torque.
Bottom line for me is that it should be much more efficient and have a longer tank range than the other engines, for the type of driving and charging I will be doing. I can’t understand a scenario where someone would get a PHEV and not install a level 2 charger to optimize electric usage.
