Chrysler may re-enter the domestic CNG market with rebadged Fiats.

The Fiat Panda has been a popular CNG vehicle in Europe, and it may be coming to the United States as a Chrysler. Last year Fiat sold 130,000 CNG powered vehicles in Europe, 60,000 of which were Pandas. ADAC (the German equivalent of AAA) deemed the Panda the Most Economical Car in Europe as it was able to go further than any other European car on €30 worth of fuel.
