What is the EV driving range for the PHVs?
The lithium-ion battery powered PHV has approximately 13 miles of EV only driving range. Range will vary based on a variety of conditions and driving styles. What is the EV driving maximum speed for the PHV? The PHV demonstration program vehicles can achieve highway speeds (up to approximately 60 mph) on electric only power. Why is the Prius PHV range so short? Toyota is of the belief that the smaller the battery in a PHV the better, both from a total lifecycle assessment (carbon footprint) point of view, as well as a cost point of view. Research has shown that plug-in hybrid vehicles with smaller batteries, charged frequently (every 20 miles or less) with average U.S. electricity produce less green house gas emissions than conventional hybrid vehicles. (according to a 2009 Carnegie Melon University study). And as battery size increases, so does the battery cost resulting in higher overall vehicle cost. What is the MPG and fuel economy of the Prius PHV? The federal government has not y
