Mazda CX-5 getting mild refresh

Mazda has found both critical and commercial success with its CX-5 small crossover, and seems to be endeavoring to keep the momentum up with an upcoming refresh. As you can extrapolate from the obvious lack of the usual camouflage, the company isn't reinventing anything in the very near future of the CX-5, but it does seem as thought some tweaks are in the works.
Lighting elements fore and aft appear to have gone under the knife, with the front grille and rear fascia also seemingly to be slightly revised. The side mirrors now look slicker and slightly more upscale with their integrated turn signals, as well.
In all, expect a look that's a touch fresher, without being a radical departure from the existing visage.

We go Unplugged to celebrate Mazda Miata Month

Chances are good that you, loyal Autoblog reader, have long since chosen to follow us on Twitter and 'like' us on Facebook. (If you haven't, feel free to take a second and do so right now.) Anyway, if you're one of our social media posse, you might have already heard that we're smack dab in the middle of Miata Month. We've gotten Mazda to loan us a couple of MX-5 Miatas, allowing us to say a protracted, tear-filled goodbye to the current generation (NC) of the beloved roadster, just before it exits stage right and ushers in the next generation.
You'll see a few more Miata Month items here on Autoblog after we've said our final farewell, but we absolutely wanted to make sure we created some great video evidence of our month, as well. Right down below, then, in its unfiltered-audio splendor, is the Autoblog Unplugged version of the 2015 Mazda MX-5 Miata PRHT. Your author had a pretty great time wringing out the roadster for the creation of our short vid, and we really hope you dig listening along.

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.
