There is new information found in an updated business plan that GM presented to the government on Wednesday.

The automaker is requesting an additional $2.6 billion in low interest loans to support the development and introduction of three new electric vehicles.

Specifically this is for the purpose of developing two spinoff cars from the Chevy Volt, and a third hybrid, and raises the amount GM is requesting from the section 136, or ATVMIP loans to $10.3 billion. These loans are intended to help companies build advanced technology high efficiency vehicles and are not related to the government funding GM currently possesses.

GM wouldn’t be able to get these loans, which could be released as early as June, until they are deemed financially viable. However this information confirms that GM has production plans to build two more EREVs, proving they do not intend the Volt to be a one-off or niche car. Building multiple models in increasing volumes is the primary way to drive costs down for the battery technology.

GM has previously unveiled the strikingly designed Voltec-powered Cadillac Converj which could conceivably be one of those two cars.

GM-Volt.com has been told that one or more additional Voltec concepts would unveiled in 2009. There is speculation that one could be a Buick, perhaps based on the new China-based Excelle which sits atop the same compact delta platform the Volt and Cruze use.

Even if GM has to go through a quick-rinse bankruptcy to cleave off its bad assets, the company will survive lean and mean and if all goes to plan with at least electric cars to choose from.
