Popular Mechanics‘ Ben Stewart took a few laps in a prototype Toyota Prius that can be plugged into a wall outlet to recharge its batteries. He says it seems likely that the next generation Prius, a 2009 model, will feature plug-in technology.
The most impressive part of the system was that it can take 1/4 to 1/2 throttle without engaging the gasoline engine. And that means for short 3 to 4 mile commutes, one could conceivably get to work and return home solely on electric power. The hybrid mode works much like the current car, engaging the internal combustion engine much sooner. This mode, it is presumed will be most applicable to long trips, when charging the battery isn’t an option.
The power still has to come from somewhere, of course, but putting plug-in options into the most popular hybrid car is a good thing, as it widens the variety of sources from which the power can be obtained, be it from regional power plants or home zero-point dynamos.
