Mazda2 Gets Miller-Cycle Engine



Mazda’s new 2 subcompact will get its power courtesy a Miller-cycle engine, when it goes on sale in Japan in July.

The Miller-cycle engine has shown up before in Mazda’s Millenia sedan. In this application, it’s a 1.3-liter powerplant combined with a continuously variable transmission to reduce fuel consumption by 20 percent. It could reach the equivalent of 54 mpg in the Japanese cycle, according to figures issued by Mazda. Emissions will be 75 percent below 2005 levels, Mazda adds.


Miller-cycle engines delay the closing of their intake valves, to reduce pumping losses and improve thermal efficiency. They’re also typically used in tandem with a supercharger — a performance enhancement Mazda does not mention in their release.


The 2, called the Demio in Japan , could be the foundation for a new Ford subcompact coming to the U.S. Smaller than the outgoing model by almost two inches, the 2 is based on a new platform that’s also 220 pounds lighter than the previous car. Along with the 1.3-liter, a 1.5-liter and a 1.4-liter diesel will be offered.


Mazda says that it will not sell the 2 in the U.S., but Ford has acknowledged it is developing a subcompact vehicle for the U.S. ; that vehicle is likely based on the new 2.
