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.

Japan carmakers vouch for safety of some Kobe Steel parts

TOKYO — Four Japanese automakers on Thursday said they found no safety issues with aluminum parts supplied by Kobe Steel Ltd, allaying some concerns that falsified quality data on products from the steelmaker had compromised their vehicles. Kobe Steel shares surged after the car makers' statements, but the steelmaker still has to contend with a U.S. Justice Department probe, while checks continue at hundreds of companies involved in complex supply chains spanning the globe. Japan's third-biggest steelmaker admitted earlier this month it falsified specifications on the strength and durability of aluminum, copper and steel products, along with materials for optical disks. The falsifications stretch back for more than 10 years, a senior executive told Reuters this week. Since then, global automakers, aircraft companies and other manufacturers have scrambled to identify potential hazards in their products. Toyota, Honda, Nissan and Mazda said that hoods and other exterior parts used in their cars which were made from aluminum directly supplied by Kobe Steel were safe. Kobe Steel shares ended the day nearly 7 percent higher but are still down by more than a third since it announced the data falsification. Automakers are still making checks on other parts, including those that they received through their parts suppliers. "We confirmed that the materials satisfy applicable statutory standards, and our own internal standard, for key safety and durability requirements for vehicles," Toyota said in a statement. Toyota, one of the world's largest automakers, identified aluminum plates supplied by Kobe Steel for the hoods and rear hatches of Toyota and Lexus brand vehicles. Though outside the automaker's specifications, they were still safe to use. While Subaru and other carmakers said they were still investigating the issue, the announcements by Toyota, Honda, Nissan and Mazda suggest that Kobe Steel's cheating scandal may have a limited impact on product safety."SERIOUS SITUATION" Nonetheless, the company's fate hangs in the balance while checks are being carried out. It must report to Japan's industry ministry by around the end of next week on any safety concerns and provide a more extensive account of the problems a fortnight later. Industry leaders have reached a consensus that Kobe Steel is in a "serious situation," a senior Japanese manufacturing executive told Reuters.

Forza Horizon G-Shock Car Pack brings Nissan IDx, Subaru Brat [w/video]

With winter's icy grip around much of the nation, now may be the perfect time to sit inside at night and enjoy some video games. The latest six-car G-Shock pack for Forza Horizon 2 on the Xbox One is now here, and it gives players a very eclectic group of vehicles to race around the game's open world. This month's group of vehicles spans the decades ranging from 2015 back to 1953. The newest and only concept of the group is the 2015 Nissan IDX Nismo. Since the production chances for this retro coupe look increasingly slim, this game might be your only chance to get behind the concept's wheel. However, if you prefer driving something a bit more classic and Italian, the 1953 Ferrari 500 Mondial is available. To add one more flavor of performance, there is the 2010 Mazda Mazdasped 3 hot hatch, which is also this month's free car for download. In addition to three takes on the sports car, Turn 10 is also offering a trio of off-roaders. The quirkiest among them is the 1980 Subaru Brat GL, which features two jump seats in the back to avoid the dreaded chicken tax. If you prefer something more boxy and American, then the 1975 Ford Bronco is sure to please. Finally, for some real power to get through the mud, there's the 2013 Ford F-150 SVT Raptor as tuned by Shelby with a supercharged 6.2-liter V8 making 575 horsepower. As usual, the whole pack costs players $5 to download, or it's free as part of the season pass. Scroll down for a brief video showing all of these virtual rides off and read the press release about them from Turn 10 Studios. This content is hosted by a third party.
