Chrysler put its electric vehicle efforts center stage for the Detroit auto show with a display of the latest versions of several production-intent EVs. The lineup included the Chrysler Town & Country EV minivan, Jeep Wrangler Unlimited EV and the Jeep Patriot EV.

Chrysler also unveiled the all-electric plug-in Dodge Circuit EV, a Lotus Exige-based electric concept with an estimated range of 150-200 miles. The latest iteration now has its Dodge cross-hair grille and other Dodge styling elements fully in place. The Town & Country, Circuit and Wrangler Unlimited were shown publicly last summer, but the Patriot is an all-new entry to the portfolio of models developed by ENVI, Chrysler’s environmentally friendly car engineering arm that draws its name from the first four letters of “environment.”

Chrysler has said it plans to put at least one of the electric vehicles into production in 2010; the company now promises at least three more EV models will follow by 2013.

“Chrysler’s broad portfolio of electric vehicle prototypes clearly demonstrates that we are well on our way to bringing electric vehicles to our consumers’ garages,” said Frank Klegon, Chrysler executive vice president for product development.

Between its ENVI electric-drive vehicles and GEM neighborhood electric vehicles, Chrysler wants to put 500,000 of its electric vehicles on the road by 2013.

Other ENVI vehicles include:

-— The Jeep Patriot EV, which combines ENVI’s range-extending drive system with a compact front-drive sport-utility vehicle.

-— The Jeep Wrangler Unlimited EV uses a range-extending electric powertrain in an off-roader. Though only a 4x2 drivetrain as shown in Detroit, a 4x4 version is in development.

-— The Chrysler Town & Country EV, incorporating the same powertrain into its utilitarian front-drive seven-passenger minivan.
