Ready for some fun?
Mazda has unleashed their newest generation innovation SKY ACTIV, an engineering masterpiece using advanced technology comprised of high-compression, direct injected, 2.0 liter in-line four cylinder. This new concept delivers Mazda’s reputation for their sporty drive, with unparalled pursuit in powertrain efficiency.
The idea of “sky” hones in on Mazda’s aims to maintain cleaner skies and air, while delivering absolute driving pleasure. Mazda is known for their unconventional approach to efficiency and technology, “Sky’s the limit” is taking on a whole new dimension for them.
“Improving fuel efficiency and reducing CO2 emissions is not just a goal at Mazda, it’s part of our business plan; we will make vehicles that are safer for our environment,” said Jim O’Sullivan, president and CEO, Mazda North American Operations. “We will increase our fuel economy globally by 30 percent by 2015 and offer affordable eco-friendly vehicles to all Mazda customers, not to just a limited segment of the market. The SKY Concept powertrains will play a big part in making this happen.”
Mazda uses internal combustion technology in both the gasoline SkyActiv-G and diesel SkyActiv-D engines. While a normal gasoline engine gets a compression ratio of about 10:1, here in the states the new skyactiv-G has a 12:1 ratio. The high compression technology is more advanced due to a longer 4-2-1 header. This header manages the back flow, minimizing the amount of hot exhaust blowing into the combustion chamber, reducing knock and blowing holes in pistons. With an improved aerodynamic design, SkyActiv-G’s most impressive factor is the 15% improved fuel efficiency. Sky-Activ-D has improved fuel efficiency up to 20%. Instead of a normal diesel compression ratio of 18:1, Mazda found that a lowered compression ration of 14:1 allowed for the fuel and air to mix better, burning more completely for their diesel engine.
The CX-5 will get Sky-Activ engines in early 2012, the diesel SkyActiv-D will be late 2012.
The 2012 Mazda 3, already at the top of it’s class in fun, compact cars, is currently being sold with Sky-Activ-G engines. This powerful dynamic adds greater impact to Mazda’s renowned “zoom zoom” power and quicker shifting. At 12:1 compression the 2.0 Liter goes from 148 peak hp to 155 hp, with torque increasing 10 percent to a 148-lb-ft peak, rising 15% in mid and low ranges. The engine contains an electronically controlled oil pump that reduces friction, with a newly designed water pump and fins to cool the radiator.The fuel economy is 28 mpg city/ 40 MPG highway.
Sky-Activ’s automatic contains a multiclutch torque converter that locks up often, and quicker. With a re- engineered six speed manual, you’ll get shorter throws and reduced friction and more efficient routing of torque throughout the gears. The electrohydraulic system makes for tight and direct steering. With a lighter chassis, this drive is smooth, fast while hugging corners tightly. Perfect for all driving types.

In our economic times, the most important factors are fuel mileage and engine durability. This catchy, spritey little engine masters both topics, while being an advancement for our future. The cost of SkyActiv technology is the same as conventional distributing, making this option far more attractive. According to Mazda engineers, this is just the beginning of a long and fruitful phase of pioneering engines that suit our economy and it’s more sustainable needs. A promise for car enthusiasts, eco-conscious and everyone along the spectrum.
