Though the Nissan LEAF and the Chevy Volt garner most of the media attention, the Toyota Prius Plug-in Hybrid was the vehicle that lit up the US sales chart in April by outselling all other available plug-in vehicles.

The Toyota Prius Plug-in Hybrid went on sale in the past few weeks, without the fanfare that usually accompanies rollouts of new plug-ins. Maybe that's because the Prius Plug-in Hybrid is a hybrid first, and a plug-in second. This begs the question if owners will even bother to plug in on a regular basis.

Now that the Prius Plug-in is set to officially go on sale in the US, Toyota has released its EPA-confirmed numbers. According to Toyota, the Prius Plug-in has an electric-only range of 11 miles, but returns an impressive 95MPGe (miles per gallon equivalent) in hybrid mode.

The ship carrying the first Toyota Prius Plug-In Hybrid production units made a delivery at the port of Benicia, Calif., near San Francisco, over the weekend. The Eminent Ace cargo ship is now headed to the port in Long Beach to deliver more of the first Priuses equipped with a plug to thereby push its efficiency close to 100 miles per gallon.

Toyota will reportedly update its fuel economy figures for the 2012 Prius Plug-in Hybrid ahead of the vehicle's March 2012 launch. According to Toyota Division Group vice-president, Bob Carter, the 2012 Prius Plug-in returns 95 miles per gallon equivalent (MPGe) in electric-only mode and 50 miles per gallon in hybrid mode.
