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. MAZDA SKYACTIV® TECHNOLOGY SETS RECORDS IN FEBRUARY - Mazda Celebrates Grand Opening of All-New Production Facility in Salamanca, Mexico - IRVINE, Calif., March 3, 2014 /PRNewswire/ -- Mazda North American Operations (MNAO) today reported February U.S. sales of 24,431 vehicles, representing a decrease of 2.4 percent versus last year. Year-to-date sales through February are down 6.7 percent versus last year, with 43,155 vehicles sold. Key February sales notes: Mazda's SKYACTIV® TECHNOLOGY accounted for 83.2 percent of all vehicle sales during the month of February. This is the largest percentage of Mazdas equipped with SKYACTIV TECHNOLOGY sold in one month, and second-best month of total volume ever with 20,245 vehicles sold. Mazda6 experienced its second-best February since 2008 with 3,945 vehicles sold, representing an increase of 46.0 percent, year-over-year (YOY). February 2014 was CX-5's best month ever with 9,353 vehicles sold, good for an increase of 71.6 percent, YOY. February was one of the most historic months for Mazda as it celebrated the grand opening of its all-new engine and vehicle assembly plant in Salamanca, Mexico.

Mazda recalls 374,500 vehicles because of Takata inflators

The Basics: Mazda will recall 374,519 examples of the 2003-2008 Mazda6 manufactured from May 29, 2002, to May 5, 2008; the 2006-2007 Mazdaspeed6 built from July 1, 2005, to June 29, 2007; and the 2004 RX-8 made from June 25, 2003, to June 30, 2003. The Problem: These vehicles contain front passenger airbag inflators from Takata that could rupture in a crash. If this happens, it could spray metal shrapnel at an occupant, which could seriously injure or even kill the person. Injuries/Deaths: The report from the National Highway Traffic Safety Administration didn't mention injuries or deaths, but Autoblog reached out to Mazda for confirmation. Takata's rupturing inflators allegedly have links to nine deaths globally and around 100 injuries. The Fix: Mazda dealers will replace the passenger side airbag with a new one. If You Own One: Mazda has not said when the replacements for these vehicles will begin. Experts believe that prolonged exposure to high humidity can cause the inflators' ammonium nitrate propellant to ignite too quickly in an accident. More Information: This recall is a nationwide expansion of Mazda's passenger's side airbag recall, which was previously limited to high-humidity regions. The population now includes 310,592 additional examples of the Mazda6, Mazda spokesperson Tamara Mlynarczyk tells Autoblog. The company discovered this new issue after Takata tested an inflator taken from a Mazda6, and it ruptured, according to NHTSA documents (PDF). The company already had a national safety campaign to fix the driver's side airbags in these vehicles.

The inflators in the front passenger air bags are susceptible to rupture in the event of a crash necessitating the deployment of the front passenger air bag.
