Plug-in Toyota Prius coming in 2010, prototype averaging 65 mpg

The upcoming Toyota Prius plug-in hybrid has been averaging 65 mpg in combined gasoline and electric-mod testing according to Bill Reinert, Toyota Motor Sales USA’s national alternative-fuel vehicle manager.

“That is real-world driving,”¬†Reinert told Automotive News. “I ask my guys to drive them as you drive your normal Prius.”

The 2010 Toyota Prius, with its parallel hybrid and nickel-metal hydride batteries, averages an estimated 50 mpg. Sales of the plug-in hybrid Prius will begin sometimes after 2010.

At the 2009 Detroit Auto Show, Toyota said it will globally lease 500 Prius PHVs powered by lithium-ion batteries. 150 of the plug-in Prius models will come to the U.S. The lithium-ion battery packs are mated to a 1.8L 4-cylinder engine.
