A compisron about the 2011 volt and Prius PHV
Stand alone Video Player
We measured gasoline mpg by driving test loops with a discharged battery — pretty standard stuff. But we also measured electricity consumption by driving a known distance and then using a special meter to determine how many kilowatt-hours of juice passed through the charge cord during the subsequent battery recharge.
After crunching the data, here are the Edmunds Observed figures we came up with:
EV-mode electricity consumption (*kWh/100 miles) *unlike mpg, smaller is better:
Prius PHV 23.2
HV-mode (hybrid vehicle) gasoline fuel economy (mpg):
Prius PHV 47.2
EV-mode electric range (miles):
Prius PHV 14.6
Driven the same way, our Prius PHV used 34 percent less gasoline in gasoline-hybrid mode and 41 percent less electricity in EV mode than the Volt.
