The plug-in hybrid model is called the Fusion Energi, and it will have a 1.6-liter gas engine, a lithium ion battery pack, and a fuel efficiency rating of more than 100 MPGe.

Ford announced today that its next-generation midsize Fusion sedan will be available in gasoline, hybrid and plug-in hybrid versions, all with an assortment of fuel-saving features. Several choices of engines and automatic and manual transmissions offer options to those too timid to go all the way and get one of the new Focus Electrics.

The plug-in hybrid model is called the Fusion Energi, and it will have a 1.6-liter gas engine, a lithium ion battery pack, and a fuel efficiency rating of more than 100 MPGe. The company has given no firm delivery date, saying only that the new PHEV will be “arriving” in fall of 2012.

All the new Fusions feature various high-tech gimmicks with trademarked names, including Lane Keeping System, Adaptive Cruise Control, Active Park Assist, Blind Spot Information System and Auto Cappuccino Brewing (just kidding on the last one).

"Our vision for Fusion was clear – deliver the very best of what One Ford stands for," said Ford VP Derrick Kuzak. "We brought our global teams together around a blank slate with the charge to develop a midsize car with groundbreaking design and jaw-dropping fuel economy – one that featured technologies to help make our customers safer and better drivers. This car is the result."
