The point is either your lucky and your average commute can be made in under that 30 then you recharge at work and make it home with no gas usage.
or local errands done all under that 30.
or you switch it to use electric and gas at the same time and probably average anywhere to 40-50 mpg as...
Pretty sure the only “known” information is as follows...
2.0 turbo engine
Only unlimited models
Approximately distance of 30 miles when using electric only.
Everything I see/read seems to repeat these things. Well just have to see Come the 3rd.
