Ronn Motor Company, a Texas-based startup, just unveiled its Scorpion roadster today at SEMA (Specialty Equipment Market Association) in Las Vegas. It's a hand-built hydrogen-burning "eco-exotic" that the company claims will achieve a 40 mpg average while belting out 450 horsepower, according to Autopia. The Scorpion's hydrogen-delivery system uses electrolysis to convert water into gaseous hydrogen, which is then mixed with 91-octane gasoline to reduce emissions and improve fuel economy.

The company's main goal is to license the technology, it seems, not sell cars, although they've committed to building 200 Scorpions in the process to prove the technology works and is reliable. "The Scorpion is significant because it uses what the company calls real-time hydrogen delivery as part of an original factory design," the report said. "And unlike BMW's Hydrogen 7, Scorpion does not keep any 30-gallon tanks full of liquid hydrogen lying around" at near-absolute-zero (roughly -423 degrees Fahrenheit) temperatures.

The Scorpion's 3.5-liter six-cylinder engine is sourced from Acura, the report said. The car features a chrome-moly chassis, carbon-fiber body surrounds, a twin-turbo on that V6, a 2,200 pound-curb weight, and a projected top speed of over 200 mph. Expect a sticker price of around $150,000; no word yet on a production date.
