Startup automaker makes another run at cheap three-wheeled transportation

Startup company Elio Motors is closer to achieving its goal of selling an American-made, three-wheel vehicle by securing a former General Motors plant in Louisiana. The lease and financial assistance from the state moves the low-cost Elio "car" closer to a production reality.

With a target price under $7,000, the Elio tandem two-seater looks like an Automotive X Prize contestant. During that 2010 competition, we saw numerous thrifty vehicles combine two- or three-wheels with a variety of small engine or alternative powertrains to achieve extreme fuel efficiency. Most existed as proof-of-concept prototypes, and precious few will ever see production.

Consider the Elio to be X Prize realized. This new model will have a gasoline engine driving its two front wheels; the company promises fuel economy of 84 mpg. That's the kind of fuel economy you'll likely see from a scooter. The price is also comparable to some high-end scooters. .

The Elio has a single door on the left and rides on three wheels so it can be registered as a motorcycle and avoid emissions, fuel economy, and safety certifications. That also means it will be able to drive solo in carpool lanes.
