Lotus Engineering has been hard at work developing new engine technologies that allow the use of sustainable alcohol fuels. It's recent Exige 270E Tri-Fuel concept showed that the British firm knows how to make an engine run on various fuels, including gasoline, ethanol and methanol. In fact, the 270E Tri-Fuel concept was the most powerful Exige ever conceived by the Hethel-based company and made its highest power output using synthetic methanol fuel. Lotus has started a new research project called the OMNIVORE engine -- cleverly indicating that it will run on anything -- that uses a single cylinder with direct injection and a variable compression ratio in order to maximize power and efficiency while running on various alcohol fuels. The higher octane rating of alcohol fuels will allow the engine to run with higher compression, thereby offering more power, while also toning itself down to run on lower-grade fuels as well.
