Lotus Teases With a Fuel-Agnostic Two-Stroke Engine

JohnnyBGod writes "Lotus claim to have invented a new, more efficient engine design. The two-stroke, flex-fuel engine can achieve, according to the surprisingly technical press release, 'approximately 10% better [fuel consumption] than current spray-guided direct injection, spark ignition engines.' The engine has a sliding puck arrangement to control its compression ratio, and has direct injection and a wet sump, to eliminate fuel leakage to the exhaust and the need to mix oil with the fuel, two common problems with two-stroke engines. Lotus engineering have released a video explaining the engine's operation."

Re:10% improvement isn't that much

You've missed the Flex-Fuel. It will run on any variation of ethanol/gas mixture, from E5 all the way up to E100. You decide how green you want to be and this engine will adapt to your choice of fuel.
