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

No one outside the USA uses corn for ethanol. It's only grown in the USA because it gets stupidly high government subsidies making it cheaper than everything else. If you drive across France, you'll see lots of bright yellow fields growing rapeseed, which is used to produce fuel.
