At the beginning of October Mayflower unveiled its e3 engine concept; an engine that promises great savings in both fuel and emissions. The engine still uses conventional internal combustion principles but in this case it can dynamically vary its capacity and compression ratio to suit the conditions and driver demands. The engine's inventor, Dr Joe Ehrlich, Formula One Champion Sir Jack Brabham, Mayflower CEO John Simpson, CEO Mayflower Engines Mike Bryant and non-executive director, Rt Hon John Major were there to launch the concept.
