Mazda announced it will introduce its next generation Sky powertrain in North America in 2011.

The gasoline-based Sky-G engine and Sky-Drive automatic transmission system will make their way into production models in 2011 while the diesel-based Sky-D engine (pictured above) will reach North America in 2012.

The Sky powertrain concept is part of Mazda’s goal of improving fuel efficiency by 30% by 2015.

The Sky-G will have 15% better fuel efficiency than current engines. The Sky-D will see a 20% improvement as well as having improved torque.

Mazda says the six-speed Sky-Drive transmission will improve fuel efficiency by another 5% while offering the performance of a dual-clutch transmission.
