Ford’s new baby engine

Ford has developed a tiny three pot petrol engine capable of powering its MPV.  Contrary to the usual practice of having a wide bore to allow large valves in the head, Ford has used a long stroke engine and overcome the limitations of poor breathing by using forced induction.  You would expect this to be a recipe for poor fuel consumption due to pumping losses – yet the laws of Physics seem to have been bent.  This engine is claimed to be both powerful and fuel efficient.
