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.

Why Mazda did so well and Volvo so poorly in Consumer Reports survey

The poor performances of Tesla and all three domestic automakers got the headlines in Consumer Reports magazine's latest reliability survey, but there were other results that caught our interest. Tiny Mazda notched the biggest gain among the 29 brands included in this year's list, leap-frogging nine spots to No. 3. Buick, which was in the top 10 last year, fell 11 spots to No. 19, the biggest decline of any brand. And then there's Volvo, a brand often vaunted for its quality and reliability, dropping six spots to dead last. What gives? For starters, all three brands benefited or suffered in large part due to their relatively small portfolio of vehicles. So when raves or complaints rolled in for even one particular model, as was often the case, it weighed heavily on the entire brand. That's especially true when it involves a relatively high-volume, hot-selling model such as the Buick Enclave (more on that in a moment). Mazda fared as well as it did despite the CX-3 losing Consumer Reports' influential "recommended" status due to problems with its climate system, including leaks from the condenser and refrigerant unit that triggered a service bulletin from the automaker in late 2016. Deputy auto editor Jon Linkov said that scratch didn't hurt the overall brand, since the CX-9 crossover and MX-5 Miata both jumped up to replace it on CR's list of newly recommended vehicles, thanks to several back fixes Mazda made to both models. For Buick, the redesigned Enclave SUV earned a "Much Worse Than Average" rating after owners reported problems with the new nine-speed automatic transmission it shares with the Chevrolet Traverse as well as some issues with the climate system. There were issues with rough shifting, plus complaints about the torque converter that necessitated fixes to the computer or outright replacement. "Again, similar stuff that we saw with the Traverse: both first-year vehicles, similar powertrains," LInkov said. He said all-new vehicles or redesigns typically fare poorly in CR's reliability survey due to issues that are hard to suss out before vehicles go into everyday use by consumers. The top-selling Encore and Envision fared well, Linkov said, but were outdone by the Enclave's problematic transmission components. The Enclave was Buick's second best-selling model through September at 35,227 units. Then there is Volvo, about which there is one word to sum up its woes: infotainment.

Mazda2 sedan images released ahead of Thailand reveal

Mazda will let customers put some junk in the trunk of its Mazda2 with the introduction of a new four-door model at the upcoming Thailand International Motor Expo on November 28. While the show is still days away from beginning, the Japanese automaker is already spilling some of the details about the sedan variant of its fetching subcompact. The four-door and traditional hatchback versions of the Mazda2 will both hit Thailand in early 2015. The two of them are essentially identical other than the added trunk and adjusted rear styling for the sedan. It basically makes the model look like a shrunken down version of the Mazda3 sedan, which isn't a bad thing at all. The company has big expectations for the little car because they're already Mazda's bestselling passenger models in Thailand. Both models will be sold with the SkyActiv-D 1.5 diesel in Thailand, which gives them lower taxes under the government's low-emission, compact car incentive plan. According to a previous rumor, a gasoline-fueled mill could join the lineup eventually, too. There's also gossip that the Mazda2 sedan could eventually be sold in Australia and Europe, but US sales are still a mystery. When asked about the four-door here, Mazda spokesperson Eric Booth told Autoblog, "We'll have more to say on Mazda2 at a later date. Right now, our focus is on the launches of the all-new CX-3 and MX-5 as well as the refreshed CX-5 and Mazda6." The company is showing all of those models at this week's Los Angeles Auto Show. Mazda to Debut the All-new Mazda2 Sedan at Thailand International Motor Expo - Goes on sale in Thailand alongside the hatchback model early 2015 - HIROSHIMA, Japan-Mazda Motor Corporation will debut the sedan model of the all-new Mazda2 (known as Mazda Demio in Japan) at the Thailand International Motor Expo 2014*1 on November 28, 2014. The all-new Mazda2 compact sedan features handsome proportions and bold styling, a high-quality, sporty interior and a combination of excellent driving performance and outstanding environmental and safety performance. The all-new Mazda2 hatchback will also be exhibited at the expo; the first time the model has been displayed to the public in Thailand. Both the sedan and the hatchback feature the SKYACTIV-D 1.5, Mazda's newly-developed small-displacement clean diesel engine. The all-new Mazda2 goes on sale in Thailand in early 2015.
