Despite the fact that Fisker received a huge blow after the U.S. Department of Energy (DOE) froze the company’s access to the federal loan it was awarded for engineering the Karma (US$169 million) and production of the midsize Project Nina sedan (US$359 million), the California based automaker continues to move on with its plans, or at least it claims to do so.

Today, Fisker sent out an invitation for the New York International Auto Show in which it included a sketchy teaser of what is assumed to be the new Project Nina sedan that will slot beneath the larger and far more expensive Karma.

Here’s what the invitation said: “Fisker Automotive is holding a special event ahead of the New York Auto Show to share with media, retailers and the public a business update and give a glimpse of the future of our company.”

We’ll have to wait for the NY show to learn what kind of progress the company has (or hasn’t) made with the sub-$50,000 Nina after Fisker was forced to push back its launch date from 2012 to mid-2013.

Previously, Fisker had signed a deal with BMW to get the German firm’s new 2.0-liter supercharged TwinPower engines for the hybrid Nina.
