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.

California adapts ZEV mandate with PHEVs for smaller automakers

California is the nation's largest market for zero-emissions vehicles with over 100,000 of them estimated to be on the roads there. The state's goal is to keep that number growing every year. To that end, the California Air Resources Board is now tweaking its rules in a way that might not boost ZEVs but could mean more plug-in hybrids for the Golden State. Jaguar Land Rover, Mazda, Mitsubishi, Subaru, and Volvo asked for an exemption to the state's zero-emissions vehicle mandate last year due to their relatively small development budgets compared to larger automakers. CARB denied their request but did craft a compromise, according to Automotive News. Rather than being required to offer a ZEV in the state, companies with an annual global revenue of less than $40 billion, like those in this group, may instead sell plug-in hybrids to earn ZEV credits. The companies aren't completely off the hook, though. If these plug-in hybrids don't earn enough credits, the corporations must buy them on the market to make up the difference. Automakers with popular electric models like Nissan and Tesla have made a big business through this trading system by selling their surplus to rivals. Tesla alone pocketed $51 million in the first quarter from this part of its business, according to Automotive News. The changes to the regulations also aren't set in stone, yet. CARB is meeting in 2016 and could adjust things further at that time.

Mazda Hazumi Concept shows up ahead of Geneva

Last week, Mazda officially teased its Geneva-bound Hazumi concept, showing little more than an aggressive headlamp design. But now, thanks to the magic of the Internet, another rendering of the Hazumi has appeared on the web, and, well, it's totes adorbs.
In Mazda's original release from last week, we were told that the name "Hazumi" means "spring up" or "bound" in Japanese, and is "particularly well-suited to a small car that appears to be bursting with energy." And now that we're getting a nearly full glimpse of the thing, we absolutely have to agree. The company's Kodo design language offers aggressive style in a cute little shape, and the usual raft of concept car-spec treatments (no mirrors, huge wheels, etc.) make it look even more comical and delightful.
Indeed, the Hazumi is understood to preview the next Mazda2 subcompact, and if this concept car points the way forward for Mazda's tiniest hatch, consider us totally geeked. Mazda is also set to debut its new 1.5-liter Skyactiv-D diesel engine at the Geneva Motor Show next week, and while the company hasn't confirmed if that powerplant will make its way into the next Mazda2, it sure makes sense, at least overseas. Stay tuned.
