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.

2016 Mazda MX-5 Miata first in-car observations

We've had few days to digest the all-new 2016 Mazda MX-5 Miata since the roadster was first revealed on Wednesday evening when we offered you our first impressions. Since that time, we've gone back and looked at the car a number of times in person here in California, and we've even seen it briefly run under its own power (okay, it was more of a saunter). What we didn't get the chance to do at the reveal, however, was sit inside the car. We've since been able to remedy that, and while we haven't been allowed to drive the new roadster, we do have some initial in-car impressions to share with you.
First, the location and feel of the major controls is quite excellent. The three-spoke steering wheel is an MX-5 specific item - it's not shared with any other Mazda. That's vital, because others would likely be too big in diameter or have the wrong rim thickness. The wheel's redundant controls seem to be well laid out and the airbag boss is very small. The column tilts, but unfortunately and somewhat inexplicably, it still doesn't telescope.
Pedals are well-spaced, and the six-speed manual has the same short throws and positive engagement that we've come to know and love.

2014 Mazda3 breaks cover early, in Euro-spec at least

We're set to get a closer look at the US-spec 2014 Mazda3 later today, but AutoExpress has the first peek at the machine's European cousin (after initial leaks reportedly came from a Czech outlet). The photos show a compact that's taken plenty of design inspiration from its older sister, the Mazda6. That's excellent news, as the larger car's dynamic front fascia, accentuated fender arches and long nose translate well to the Mazda3. Inside, there are are new and improved material choices, and the longer wheelbase means occupants get to enjoy more room than before. There's also a larger trunk with 12.3 cubic feet of cargo capacity.
Buyers in the EU can get their hands on a 1.5-liter Skyactiv-G gasoline engine with 99 horsepower, though the old 2.0-liter four-cylinder will still be available in either 118 hp or 163 hp configuration. A 2.2-liter diesel tops out the engine choices.
The 2014 Mazda3 is lighter than its predecessor and boasts disk brakes and a multi-link rear suspension on every trim. That means this thing should be fun to shuffle around. Stay tuned for details on the US-spec variant later today, including a lot more images of the good-looking hatch.
