At the 2010 New York Auto Show, Mazda revealed plans to bring its next-generation powertrain technologies to the US market. This includes the two new engines and an advanced automatic transmission that were introduced last October that represent tremendous fuel savings.
Mazda grouped the SKY-G direct injection gasoline engine, SKY-D clean diesel engine, and SKY-Drive high-efficiency automatic transmission under the 'SKY' family of technologies.
The SKY-G range represents the first engines to be initially unveiled in the US in 2012. Mazda's next-generation gasoline engine will be the core powertrain in future Mazda vehicles. It is expected that SKY-G will boost fuel efficiency by about 15% but at the same time, engine power will be increased as well.
These engines are also equipped with the SKY-Drive automatic transmission, which also improves fuel economy by 5% more, while achieving a direct-performance feel similar to that of a dual clutch transmission.
After the SKY-G and SKY-Drive in 2011, Mazda will also launch its SKY-D clean diesel engine in the US sometime 2012.
This engine will first appear in a new mid-sized car and it is claimed to offer fuel economy as high as 43 mpg on the highway. This is certainly a better figure than many hybrids currently on sale; it is also 20% better than Mazda's own 2.2-liter dieselsold overseas.
