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.

2020 Mazda3 Review & Buying Guide | The connoisseur's choice

Completely redesigned last year, the 2020 Mazda3 pretty much carries over, continuing to be the connoisseur's choice for a compact car. For starters, its elegant sedan and unique hatchback body styles are considerably more stylish than expected for this segment. Park it next to a similarly priced Honda Civic or Toyota Corolla and people are likely to think you paid far more than you did. The same goes for the cabin, which is functional yet stylishly minimalist (if a bit cramped). Then there's the driving experience, which continues to delight those who value sharp responses and a driver-focused character. The switch to a less sophisticated rear suspension for this latest generation has dulled some of its corner-taking capability at the limit, but that's a low-percentile complaint. The bigger dynamic beef is perhaps that Mazda doesn't offer a hotter version in the vein of the Civic Si or VW GTI. Yet, that falls under the category of "wishes" not "problems," which the 2020 Mazda3 has scarcely few. Perhaps it won't be for everyone in the market for a compact car, but everyone should at least consider it.   What's new for 2020? After being completely redesigned last year, updates are light for 2020. The base trim level now comes standard with the Mazda i-Activsense suite of accident avoidance tech and driver aids that continue to be standard on every other trim level. 2019 Mazda3 AWD View 33 Photos What's the interior and in-car technology like? The interior quite simply makes you go "wow." A Honda Civic or Toyota Corolla, which are actually quite nice, look and feel like they should cost substantially less – especially when comparing top trim levels. Whatever trim level of 3 youÂ’re considering, however, the key to its wow factor is how the MazdaÂ’s design removes visual clutter by reducing switchgear and effectively hiding air vents and door handles. It just looks special. It's also functional. The steering wheel, which looks sensational, is an absolute treat to hold. There's considerable center console space and Mazda's tech interface, which had lagged behind its competition due to key usability issues, has been cleaned up. The dashtop screen is large and easy to see. The knob that controls it is large, not unlike BMW's iDrive, and ergonomically placed on the center console. It's not a touchscreen, though, as Mazda engineers determined that hunting for touch-operating icons can be distracting.

Feds investigating Mazda CX-9 over suspension problems

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2007-2008 Mazda CX-9 because the lower ball joint in the front suspension can potentially separate while driving. An estimated 54,000 examples of the crossover might be affected. The investigation was prompted by six complaints of this happening on the road. Because the complaints are coming more rapidly as of late, NHTSA thinks the issue could be getting worse. The problem also appears to be more prevalent in states that use salt on their roads in the winter. None of the failures caused any injuries, and all but one happened at 20 miles per hour or slower. NHTSA's preliminary evaluations "assess the scope, frequency, and safety consequence" of a potential problem and can sometimes lead to recalls.

SUMMARY: The Office of Defects Investigation (ODI) has received six (6) complaints (VOQs) alleging incidents of front suspension LBJ separation in MY 2007 through 2008 Mazda CX-9 vehicles. The reports appear to show an increasing trend. One of the separations allegedly occurred at 40 mph and the other 5 incidents occurred at speeds between 0 and 20 mph. The first VOQ was received in October 2013, followed by 2 reports in late 2014 and 3 reports in the first 5 months of 2015. Four of the VOQs are from states using high volumes of road salts (?salt states?) which, for purposes of this investigation, include: Connecticut, District of Columbia, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin. The other VOQs were from northern Virginia, which borders the ?salt state? region, and South Carolina. ODI also identified EWR field report data related to the alleged defect in the subject vehicles. A preliminary investigation is being opened to assess the scope, frequency, and safety consequence of the alleged defect. The six VOQs associated with this investigation are: 10717510, 10714469, 10695142, 10668978, 10640541, and 10546535.
