With President Obama committing $2.4 billion in stimulus package money for the development of electric vehicle technology, US automakers may have enough incentive to make the green car plunge and help contribute to the one million plug-in vehicles the President would like to have on the road by 2015.

So-called alt energy-powered vehicles, both production or concept models, were on display at the recent New Yok Auto Show. Here's a sampling.

The 2010 Mercedes ML450 Hybrid, designed specifically for the US market, will deliver 'city' fuel consumption of 21 mpg and 'highway' consumption of 24 mpg.  No price has been set yet, but Car and Driver magazine expects the ML450 Hybrid to be priced around $50,000.

Featuring GM's Voltec electric propulsion technology, the company says the Cadillac Converj will get up to 40 miles of gas and emmission-free electric driving, with extended-range capability of hundreds of miles. When the battery's energy is low, the Converj switches to the extended-range mode. During this mode of operation, electricity needed to power the vehicle is created on-board by a flex-fuel-powered engine.

There's no price available at this time, but Motor Trend magazine estimates it will be $60,000-$70,000.

The 2009 Fisker Karma has a plug-in hybrid technology called Q DRIVE, developed by Quantum Technologies exclusively for Fisker Automotive. The Karma's Q DRIVE configuration consists of a small gasoline engine that turns the generator, which charges the lithium ion battery pack, powering the electric motor and turning the rear wheels.  The estimated starting price is $80,000.

The Fisker Karma will offer partly self-contained climate control; buyers can opt for a full-length solar roof that will help charge the car and provide cooling for the interior cabin while the car is parked. Additionally, Fisker Automotive will offer consumers an option to purchase a set of solar panels for the roof of their garage to generate electricity during the day that can be used to charge the car overnight.
