http://www.cleanmpg.com/photos/data/2/AmericanFlag.jpg Mazda's 2.0 liter four-cylinder engines paired with the new transmissions would result in a fuel economy increase to 32 mpg from 22 mpg in the city. Highway fuel economy would increase to 42 mpg (http://www.dailytech.com/Mazda+Developing+New+Engines+Powertrains+to+Boost+Fuel+Economy/article16066.htm)

looks to be 35-36mpg combined if this is on our new 08 Epa --Ed.

In May of this year, President Barack Obama proposed a 35.5 mpg nationwide average fuel economy standard that would be achieved by 2016. The average for cars will be raised to 39 mpg, while the average for light trucks will be raised to 30 mpg.

Mazda is currently known for its line of sporty vehicles, but is currently lagging its competitors in fuel economy. To remedy that, the company is implementing a complete redesign of its four-cylinder engines that will see them paired with new small and light six-speed automatic transmissions.

The new direct-injection gasoline engines will have a combination of smaller displacement, higher power output, and greater efficiency. The fuel injector is placed in the combustion chamber of a direct-injection engine, as opposed to the intake valve in a conventional fuel-injected engine. Mazda is also combining its direct-injection engines with a new electric high-pressure fuel pump and variable intake and exhaust valve timing that will allow more optimal combustion in a wider rev range. The company plans to incorporate these developments into... http://www.dailytech.com/Mazda+Developing+New+Engines+Powertrains+to+Boost+Fuel+Economy/article16066.htm

Well it's clear that Mazda is rising to the challenge by innovating. The question is whether the big 3 will do the same or just pump their money into lobbyists opposing the new CAFE standards.

Elixer,

The 2010 Equinox is rated 22/32-pretty good for a 3700 lb 187" crossover. The Malibu is pretty decent also, but the Equinox is relatively better-beating the Escape Hybrid in Hy mpg.In fact, I think it beats all SUVs on the HY,and probably is only behind the hybrids in combined EPA( granted, that is faint praise ).

Good steps, but it sounds like they're pinning this all on ATs. Sad development for the "zoom-zoom" company IMO. A properly geared 6sp MT is still going to blow a 6sp AT out of the water on the EPA city cycle, let alone what we cleanmpg'ers could do with it.

I like the quote about how they might bring a diesel engine here, but they don't have an AT that it can mate to. Of course my knee-jerk response to that is, "So? Bring it anyway!"
