Mazda3 diesel under consideration for US, hybrid not so much

It's been a long time coming, but we finally clapped our eyes on the real deal, officially official 2014 Mazda3 in hatchback form yesterday. Yet there's a lot more to learn about this next-generation version of what has always been one of our favorite compacts. We know that the US version will come with one of two Skyactiv engines, but what about alternatives? Will there be any... or will the gasoline-fed four-cylinders be powerful and frugal enough to carry the day?
According to Automotive News, the answer is a definite maybe. Mazda North America CEO Jim O'Sullivan has told the trade publication that his employer will consider adding the company's well-liked 2.2-liter Skyactiv diesel powerplant to the model down the road. However, the company first wants to see how the engine fares with American consumers in its big-brother Mazda6 sedan, a model that goes on sale later this year. As for a potential Mazdaspeed3 successor, mum is still the word.
Anything else? Uncharacteristically, Mazda will build a hybrid model of its new 3. We say "uncharacteristically," because the Japanese independent has long shied away from gas-electric powertrain tech. In fact, it's gone so far as to boldly announce its aversion to the technology, with auto show banners proclaiming "Not Electric. Not Hybrid. Not A Drag To Drive." Despite all that, this new generation of Mazda3 will in fact be the company's first full hybrid production model. According to AN, however, O'Sullivan says that the company has "no plans" to sell it in the US.

Mazda CEO closes door on talk of RX sports car revival

Some rumors in the auto industry simply refuse to die. Over the last decade, a few of the strongest have focused on Japan. A few years ago, we could have explained away the constant whispering over a new Toyota Supra, Acura NSX or Mazda RX-7 as nostalgia for Japan's golden era of performance. Today, though is different.
We already have the Nissan GT-R, and, thanks to the Toyota FT-1 Concept, a Supra successor finally appears to be on the way. Acura will someday, allegedly, deliver on its promise to put the NSX on sale. So where does that leave the third member of the Japanese performance trio mentioned above? Well, um, it still isn't happening.
"We don't have that kind of vehicle in our future product plan," Mazda CEO Masamichi Kogai told Automotive News when asked about a successor to the rotary-powered RX line. "If you increase the number of segments, then the resources we can allocate to each will decline and that will prevent us from developing truly good products."

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.
