Both machines now boast a full suite of Skyactiv efficiency technologies for the first time, and as such, are lighter than their predecessors.
The wagon debuts with a 173-horsepower 2.2-liter Skyactiv diesel engine in two power configurations, both of which conform to Euro 6 emission standards without the burden urea injection. Mazda isn't saying exactly what sort of fuel economy we can expect from the wagon, but earlier estimations put the diesel sedan in the 43-miles-per-gallon highway range. Expect similar from the five-door.
Buyers will also be able to purchase the 2014 Mazda6 with a direct-injection gasoline 2.0-liter four-cylinder good for 148 horsepower as well as a 2.5-liter gasoline direct injection engine with 189 horsepower. Like the four-door, the long roof will make use of the Mazda i-ELOOP brake regeneration system.
