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.

Fiat 124 caught entirely undisguised

Dear automakers, please continue making these kind of mistakes. Thanks to what we're guessing is some lax security, the all-new, Mazda MX-5 Miata-based Fiat 124 was spotted taking part in a photo shoot near Santa Barbara, CA. The images show what we'd consider a fairly simple rebadging job. The 124 gets new front and rear clips that not only harken back to the original 124 (not to mention other Fiat roadsters, like the Barchetta), but also serves to distance this droptop from the rest of the company's US range. The similarities between the 124 and the car it's based on are even more obvious in the cabin. This is an MX-5 interior with Fiat's big, red badge on the tiller. That means the same quality materials and knob-dial infotainment system that have been so well received in the Miata. It's under the hood, though, where the Fiat really differs from its Japanese cousin. According to our spy, the vehicle shown here features some kind of two-pedal setup – probably the six-speed Euro twin-clutch used in the 500L and Dodge Dart. Don't worry, though, a six-speed stick will also be on offer. Regardless of transmission, we can expect a 180-horsepower version of the 1.4-liter, turbocharged, four-cylinder offered in the 500 Abarth. And if that's not enough good news, a dedicated Abarth model will likely arrive after launch, which our spies claim will use the 1.75-liter turbo and DCT from the Alfa Romeo 4C. While this represents a good look at the new 124, we'll probably be waiting until the LA Auto Show in November for the official look. Stay tuned.

The 2018 Mazda6 also snags top IIHS safety rating

The Insurance Institute for Highway Safety is one of two organizations that issues important safety ratings. To get to IIHS's Top Safety Pick rating level, the 2018 Mazda6 not only had to ace a bunch of difficult crash tests, it also must have headlights that meet a strict test as well. Its stablemate, the CX-5 crossover just received the even higher Top Safety Pick+ rating. Both must be equipped with optional adaptive headlights to achieve these ratings. The rationale is, many crashes happen at dusk or in the dark, and an outsized number on unlit roads. While almost all modern headlights outperform the dim, unfocused sealed beams of the past, IIHS says that government regulations aren't doing a good enough job of ensuring real-world performance. Adaptive headlights turn with the front wheels, helping out a lot in IIHS's tests on illumination in sharp and gradual curves. Related: How the 2018 Mazda6 stacks up to its competitors in the midsize sedan segment The Adaptive Front-Lighting System is only available in the Grand Touring Reserve and Signature trim levels, meaning that you'll have to upgrade to those fancy versions to get it. It'd be nice if Mazda allowed even lower-trim buyers to add this as a stand-alone option, but for now that's not how it works. Fancy, safer headlights or no, we love the new Mazda6, especially the turbocharged version. It's one of the most fun sedans around. And, according to IIHS, now one of the safest.
