Gizmag has an article on a new engine from Toyota:

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 One liter category of the International Engine of the Year awards four years in a row from 2007-2010.

    > A diesel Clio can get 2.7L/100km. What makes this inferior engine "hyper-fuel-efficient"?

    (A) You did your math wrong, you used UK gallons, not US gallons. The Clio gets 3.2L/100km. [ultimatespecs.com]

    (B) When cars in the ~45mpg (5L/100km) range are regularly referred to as "fuel-efficient" both the toyota and the renault qualify as "hyper fuel-efficient."
