Toyota announced that they will be showing off their latest in green technology at the Frnakfurt Auto Show with the Plug-In Prius hybrid.  The all new Prius is known as the 2010 PHV or plug-in hybrid vehicle will be released later this year, with Toyota promising 500 sold to fleets world wide.

Unlike other traditional Plug-In style electric cars, the 2010 Prius PHV will only have a limited distance of 12 miles to run on battery alone.  After reaching a distance of 12 miles the plug-in battery is depleted and the Prius returns to standard hybrid mode.  The hybrid mode of this PHV is similar to that of what's found in existing model Toyota Prius's.
