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.

2015 Mazda2 spotted on the road

When Mazda unveiled the Hazumi Concept at the 2014 Geneva Motor Show, our excitement for the next Mazda2 increased considerably. The Hazumi looks to retain much of the driving character that makes the current 2 one of the very best cars in its segment while infusing it with more aggressive styling. Of course, when the 2 arrives, it won't look exactly like the Hazumi. That's why these spy photos are so important.
This is our very first look at the next-generation 2, and although the Hazumi influence might be difficult to discern, thanks to the swirly camo, it's still there. The grille shape and the headlights are very similar in shape to the items shown on the concept, while the camouflage disguises the shape of the greenhouse, which looks somewhat like the Hazumi.
What we can't see, though, is under the hood. That's where our spies come in, reporting that a pair of 1.5-liter SkyActiv engines will see action in the tossable 2. The former, which we'll almost certainly see in the US, is a gas-powered mill found in the Euro-spec Mazda3. In the larger 3, it produces 99 horsepower and 111 pound-feet of torque, which is broadly similar to what the current 2's 1.5-liter pumps out. The other engine, a 1.5-liter SkyActiv diesel, probably won't be making the trip, although we'll continue to hope.

2016 Mazda MX-5 Miata firsthand impressions and notebook scribblings

In a temporarily repurposed airport hanger in Monterey, CA, the world caught its first glimpse of the 2016 Mazda MX-5 Miata tonight, and I was fortunate enough to attend in person along with my fellow auto media colleagues, Mazda execs, a couple hundred Miata devotees and, oddly, a fair number of Duran Duran fans. The klieg lights have dimmed, Simon Le Bon is no longer ringing in my ears, and I'm left to ponder what I've seen. I've scavenged my notes - and my Twitter feed - to give you some details and brief thoughts.
Fair Warning: I can't claim to be completely impartial (I own a second-generation NB and consider the Miata franchise to be one of but a few sacrosanct franchises in modern motoring), but I will share my honest first impressions of the new car, both good and bad.
Here are my notes:
