2010 Mazda3 – Click above for high-res image gallery
Mazda gave us a glimpse of its next-generation Sky-G (gas) and Sky-D (diesel) powertrains at the 2009 Tokyo Motor Show, as well as its new Sky-Drive six-speed automatic transmission. These engines are currently running the testing gauntlet, as the first applications are expected to show up as early as next year in the refreshed Mazda6 sedan.
Car and Driver was able to snag an early test of a 2.0-liter Sky-G engine, which will reportedly achieve 30 miles per gallon in the city and 39 to 40 mpg on the highway when used in a Mazda3. This puts it in the same territory as the Volkswagen Golf and Jetta TDIs, not to mention besting smaller offerings like the Ford Fiesta and Honda Fit.
C/D also got the skinny on Mazda's 2.2-liter Sky-D diesel powertrain, which the automaker has confirmed for application in its "next-generation mid-size sedan" (*cough* Mazda6 *cough*) which will achieve up to 43 mpg on the highway. Take that, Fusion Hybrid. Head over to Car and Driver's full deep-dive for a raft of details about both of the new engines.
