Elio Motors, Inc. announced it has unveiled its new 0.9 liter, 3-cylinder engine prototype, completing one of the company's most important stages of development. With a goal of up to 84 MPG and a projected top speed of more than 100 MPH, the enclosed, three-wheeled Elio requires an engine with a unique blend of power and efficiency that simply doesn't exist on the market . Elio Motors, which plans to sell the vehicle for $6,800 when it launches in the first half of 2016, turned to world-class engine developer IAV to create a new technology that would meet the company's needs.
