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.

Mazda zooms into SEMA 2016 with lighter MX-5 Speedster and RF Kuro concepts

It's almost time for the 2016 SEMA aftermarket show again, if you haven't guessed already by the steady parade of early looks at various show cars. Mazda's MX-5 creations are generally a highlight for us, unapologetic Miata junkies that we are. This year's cars should be just as exciting as last year's, one being a revision of last year's Speedster concept and the other based on the brand new, sexy RF retractable targa top model. Both SEMA MX-5s were designed and built in-house at Mazda's Irvine design studio. This year's Speedster is somehow even lighter than before. Mazda carved 100 pounds out of it, making it a staggering 350 pounds less than a production soft top model. It's also been repainted in a color called "White Ether", which we're imagining looks something like the "Blue Ether" paintjob on last year's highly reflective Speedster minus the blue tint. Mazda will probably never sell a roofless Miata or anything this lightweight, but maybe it should. It looks like it'd be a blast to drive at a road course. And then there's the RF Kuro concept, the first RF-based SEMA show car, which is shown in the teaser above. It doesn't seem terribly extreme, to be honest. It's wearing a matte charcoal paint, which explains the "Kuro" moniker – kuro means "charcoal" in Japanese. A set of 17-inch RAYS forged wheels and MX-5 Cup suspension, and that's about it. Not to knock it; the RF is a sexy looking thing as it sits, and Cup suspension should make it handle even more like a go-kart. Of course, both concepts will be fully revealed at the show next month in Las Vegas. Stay tuned for a dose of concept Miata hotness.Related Video:

Mazda CX-5 named Japan's Car of The Year, Subaru BR-Z wins "Special Award"

The Mazda CX-5 stamped its Kodo design and SkyActiv technology authority all over the Japan Car of the Year awards, taking the top prize ahead of the Subaru BRZ/Toyota GT 86. It is Mazda's second victory in the last ten years, the 2005 MX-5 claiming the same trophy, and the fourth time the Hiroshima company has won.
The award is decided by 60 local "automotive experts and journalists," and open to any passenger car released in Japan from November 1, 2011 to October 31, 2012 that has sold more than 500 units. Each judge gets 25 votes, his or her top vote getting 10 points, the rest of the points being spread among the judge's choice for the next best four cars.
The second-place getters were the Toyobaru twins with 318 votes, the surprise being they didn't beat or get any closer to the crossover. The Subaru BRZ did claw some mojo back, earning the Special Award given to cars that have made "an exceptional impact." The BMW 3 Series was third overall and won the Import Car of the Year award with plenty of room between it and the second place Range Rover Evoque.
