Last year, we wrote about the rise of niche auto manufacturers. In two weeks, Colorado based Lightning Hybirds will debut a new sports sedan that they claim will get 100 miles per gallon at the Denver Auto Show. Called the LH4, the car is powered by a proprietary engine that mixes a 90 horsepower 2-cycle biodiesel powerplant with 150 horsepower hydraulics. The cars are slated to be available in 2010 and will sell for $39,000-$59,000.

The team at Lightning are participating in the Progressive Automotive X Prize competition. The winner will recieve 10 million dollars for winning a series of competitions in 2010 with a 100mpg hybird vehicle.
