Mazda3 to showcase CNG, Hybrid versions in Tokyo

Mazda has made huge gains in its competitive set with the introduction of its Skyactiv technologies, and the Japanese automaker appears to have no plans on slowing down. While we're still waiting for the Mazda6 Skyactiv-D diesel to go on sale in the US, Mazda announced that it will debut new Skyactiv-Hybrid and Skyactiv-CNG versions of the Mazda3 (standard US-spec model shown above) at next month's Tokyo Motor Show.
Matching up with what we heard earlier in the summer, the Mazda3 Skyactiv-Hybrid is intended for Japan only, but there are no details about this system regarding fuel economy, electric components or specs. Likewise, there are no details for the Mazda3 Skyactiv-CNG Concept, which is a bi-fuel version of the car running on both gasoline and compressed natural gas. As this car's name suggests, the CNG model is a concept vehicle, and there is no indication that Mazda plans offering such a model here in the US.
In addition to these two vehicles, Mazda will also have an Atenza (Mazda6) on display showing off some vehicle-to-vehicle (V2V) safety systems, called the ASV-5 (Advanced Safety Vehicle). Scroll down for Mazda's official press release.

The Mazda MX-5 Miata and saving a marriage

I've had the privilege of knowing Zach Bowman – former Autoblog scribe, now penning great things over at Road & Track – for nearly a decade. We met at the Detroit Auto Show when we were both relatively new to the business, and joked about how someday, we'd work together and eventually conquer the world as big shots in the industry (we're still figuring that last part out, by the way). Thus, I was thrilled when Zach joined Autoblog in 2010, just a couple of months after I was hired, and was equally saddened when I learned he'd be leaving us. Zach is someone I'm proud to call a colleague – nay, a friend – and I've enjoyed the voice he's brought to this line of work. I tell you this on a personal level because Zach has just published what you could arguably consider his most heartfelt piece of automotive work to date. It's a charming, emotional story about his relationship with his wife, and how they, like so many young couples, learned to make marriage work through the many ups and downs found in any solid relationship. I call this "automotive work" because Zach intertwines this tale into a story about driving his 2006 Mazda MX-5 Miata across the country, his wife by his side, learning about love and life from the cockpit of a two-seat roadster. I can honestly say it's one of the best things I've read in a long while. Rather than continue to wax poetic about Zach's latest piece, I'll let his own words speak for themselves. Head over to Road & Track to read the full piece.

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.
