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.

Are you the 2016 Mazda Miata?

Tech nerds are spoiled. Every year, there's a new iPhone that arrives following months and months of breathless speculation and rumormongering. We car folk have a more difficult life, because vehicles with the iPhone's cult-like devotion and following, while plentiful, only receive hefty updates after several years. Case in point, the Mazda MX-5.
There's a new one coming, and much like the iPhone 6, it'll arrive in just a few weeks. So, in lockstep with the tech folk, we're anxiously biding our time and waiting with baited breath for the expected debut date of September 3. Also, like Apple fanboys, we're clamoring over any hint or teaser as to what the next-gen Miata will bring, which is why we're showing you the above image.
That is, allegedly, the new MX-5 hiding under the sheet. Auto Motor und Sport has the image, which according to World Car Fans was released by Mazda. Of course, we've reached out to the Zoom-Zoom brand for verification of its authenticity, and will be sure to update as soon as we hear back.

2015 Mazda3 interior spied for the first time

In terms of exterior appearance, not much has changed from the last time we spotted the next-generation Mazda3 out testing. Oh, sure - we can see plenty of details that clearly show the new Kodo design influence (that front end reminds us a whole lot of the sleek new Mazda6), but these latest round of spy shots don't really show us anything we haven't seen before. Oh, wait, yes they do - the interior.
Feast your eyes on the Mazda3's insides, showing a vastly reworked interior that also takes cues from the automaker's most recently refreshed products. We can see that there's a simple, clean center stack with a slim row of heating and cooling functions, and up top there's a large, presumably touchscreen display, with redundant controls found just aft of the shifter.
We expect that the 2015 Mazda3 will debut at the Frankfurt Motor Show this September, packing both petrol and diesel engines. A sedan variant is also in the works, and should debut shortly after the hatchback.
