Toyota's astonishing new Atkinson Cycle engine delivers 78 mpg (33.16 kilometers per liter):

Toyota has announced the development of two hyper-fuel-efficient small-displacement petrol Atkinson cycle engines: a three-cylinder 1.0-liter and four-cylinder 1.3-liter which will be introduced across the range from next year in 14 different variations. The smaller engine will deliver 78 mpg (US) (33.16 kilometers per liter) in the Toyota Aygo, an improvement of 30 percent. The fuel-efficiency of the one-liter engine in particular is remarkable. The engine it will replace won the the One liter category of the International Engine of the Year awards four years in a row from 2007-2010.
