2009 Lotus Exige Tri-fuel

2009 Lotus Exige Tri-fuel

After the recent success of the Lotus Exige 270E Tri-Fuel at the Shanghai Motor Show, Youngman Auto, the lightweight English sports car builder’s Chinese partner has submitted a request that the concept go into production, at least for the Chinese market by the end of this year. The alternatively fueled Lotus made its debut at Geneva in 2008, and what set the car apart from normal flex fuel vehicles that can run on a blend of gasoline and ethanol, the Exige 270E adds methanol into the mix. It is no surprise that the Chinese are so interested in the Tri-Fuel, because back in 2007 China became the world’s largest producer and consumer of methanol. In 2008 nearly 1 Billion gallons of the alternative fuel was blended with gasoline in the panda loving country, and mixtures of methanol/gasoline are already available at many gas stations throughout the land.

Check out the diagrams after the jump to see how Tri-Fuel works.
