No, I was thinking 0-14mph.
This is the type of 'cheater' rating you see when a PHEV cannot complete EPA test loops without the ICE coming on at all. You should rate them by the MPGe to see how often the ICE comes on during the EPA cycle.
As you see in the link, the Volt is not 0-53 miles, it is 53 miles AER, and since gas engine does not come on during the EPA loops, it's 106 MPGe because of the higher efficiency of running in all electric mode during the tests. Now the Bimmer only sees 0-14 AER and 56 MPGe because it uses gas engine quite a bit to do the full EPA cycles. On the parts of the EPA test that it CAN run in AER mode, it can get 14 miles, but that's sort of cheating. A Volt will go further than 53 miles on electricity if it gets to skip the more aggressive test cycles, and it will get a higher MPGe. Chevy delivers more than EPA claims, BMW delivers less.
I know our G2 Volts when run easy with the AC on, go over 60 miles of AER and 125 MPGe, if I keep the peak speed to 65 mph, but average speed lower. Like in a congested urban freeway drive, or city driving. This is how a common low range plugin such as the X5 must be driven to reach 14 miles.
But why would I call the Bimmer Plugins weak? The X5 version can go 0-60 mph on pure electricity. However: "in EV mode the X5 xDrive40e needs 22.6 seconds to reach 60 mph" per Car & Driver. That is 1/3 the EV acceleration of the Volt.
BTW - This is why we did not end up the CT6 PHEV version. It suffers the same deficiencies as the Euro shortrange PHEVs. Not nearly as bad as the X5 PHEV, but why bother? We just selected the 3.0 TT Platinum. Why haul around 18.4 kWh of battery if you need to run it off gas anyways for acceleration. But at least the CT6 PHEV gets the full $7500 fed credit and a California HOV sticker (which requires 20 miles of range now). But it is also a message to GM. I will not buy watered down compliance cars from them. They need to make a real effort to get my dollars. Which by the way is about the same as the X5 PHEV due to the difference in fed credit.
