Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Mazda says 83 percent of new cars bear Skyactiv moniker

Mazda's US sales are down a little bit but the company's fuel economy is almost assuredly up. That's because its fuel-saving Skyactiv drivetrain technology is essentially taking over US vehicles sales. To the tune of about five out of every six vehicles sold, at least. While the Japanese automaker's US sales in February fell 2.4 percent from a year earlier, Skyactiv accounted for 83 percent of its sales last month. Most notably, Mazda6 sales jumped 46 percent from a year earlier, while Mazda CX-5 sales were up 72 percent. The company also celebrated the opening of its factory in Salamanca, Mexico, where it will make models such as the Mazda2 and Mazda3. The company is not resting on its fuel-economy laurels either, apparently. In January, it was reported the company is hard at work on its next-generation Skyactiv technology, which will boost fuel efficiency by as much as 30 percent by using diesel-like high compression. As it is, Mazda had the highest fleetwide fuel economy of any major automaker in the US for the 2013 model year with a 27.5 mile per gallon average, according to the Environmental Protection Agency (EPA). Honda came in second with 27 mpg. Check out Mazda's press release below.
