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.

Xcar tries to figure out what makes the Miata so great

Over the past 25 years and 3 model generations, the Mazda MX-5 Miata has shown that you don't have to be the best to be a massive success. The little, Japanese roadster has never been the absolute peak of automotive performance, but it's precise handling, good reliability and frugal running costs have helped make it a star. Autoblog recently tried to give you the experience of driving one on video, and now Xcar Films has made its own in an attempt to show what makes this droptop an icon.
As Xcar puts it, the Miata isn't the world's best sports car, but it is the world's favorite. When they were originally designing the roadster, Mazda's engineers took everything that made British droptops from the '60s great, and junked all of the stuff that made them a terror to own. The result was a car that would start up everyday with no fuss and get drivers wherever they needed to go with a huge grin on their face.
The fourth-generation Miata is imminently on the way for its September 3 unveiling, and the very early rumors indicate that Mazda doesn't plan to rock the boat too much with the latest one. It supposedly rides on a longer wheelbase and wider track but with the weight trimmed by over 200 pounds. Check out Xcar's video for a primer on MX-5 history and why the automotive world loves this little roadster.

Mazda3 celebrates 10 happy years

Mazda is on the cusp of unveiling an all-new Mazda3, but the compact will mark an important milestone before that happens. The very first Mazda3 rolled off of the assembly line on June 25, 2003. A decade later, the little car has snagged some 136 awards. The first generation sold 2.2 million units over the span of six years, and the second has smiled its way into the hearts of 1.4 million buyers since 2009. Mazda notes the machine even took the honor of being the top-selling passenger car in Australia in 2011 and 2012.
So, what will the future bring? The Japanese automaker is keeping the details to itself for the moment. From the spy photos we've seen, it looks as if the new design will fall under the company's new Kodo design philosophy. That same language brought us the perilously sexy Mazda6, and the new Mazda3 should be no less attractive. You can check out those photos here.
