A 40mpg hydrogen-powered sports car

Unfortunately, it's not a production model, but the first of 200 Scorpions made an appearance at the SEMA show:

The Scorpion gets its sting from a hydrogen delivery system the company calls H2GO. While cars like the Honda FCX Clarity and Chevrolet Equinox use hydrogen fuel cells to drive electric motors, the Scorpion uses electrolysis to convert water into gaseous hydrogen. The hydrogen is mixed with 91-octane gasoline to improve the fuel economy and reduce the emissions of the car's 3.5-liter internal combustion engine.

Maxwell, a 40-year auto industry vet and lifelong gearhead who holds several patents, is using the limited production — just 200 will be built — Scorpion to prove the technology works and legitimize the H2GO system the company will begin selling for $1,000 early next year. The way he sees it, if H2GO works on the Scorpion, it'll work on your Civic.

Maxwell didn't offer much in the way of specifics, saying the publicly traded company is still dotting the i's and crossing the t's on the venture. But he says H2GO is good for a 15 percent to 33 percent improvement in mileage, a noticeable increase in power and a significant reduction in overall emissions. The company is pursuing EPA certification of the Scorpion so people can get a better idea of what the system is capable of. Maxwell insists the 40-mpg figure is the real deal.

This is a better approach to popularizing alternative fuels . . . for the non-city-core car-buying public. If their next trial model is an SUV or a pickup truck, they'll have to hire a whole bunch of order-takers for middle America.
