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 16X rotary engine two years away, will arrive in all-new model

We last reported on Mazda's next-generation rotary engine project in June of 2012 when the automaker built its last Renesis-powered RX-8, but rumors of this new engine's development had been around way before that final car left the production line in Japan, last year.
We now have enthusiastic confirmation that this next-gen rotary engine is really and truly going forward. It is still referred to as 16X and has several priorities. First is to lower fuel consumption compared to the RX-8's engine, while still making gains in terms of performance. The second is to reduce the burning of oil that was happening at the highest revs. And the third and final priority, and perhaps most key for enthusiasts, is to give the powertrain a big torque upgrade.
What we were told by a Mazda USA insider (while we are all here together at the festivities in Monterey) is that the first application of the new 16X engine will be happening in two years' time in an as yet undisclosed new model. Oh, the mind races to our eternal Mazda wish list...

Mazda MX-5 Miata goes Head 2 Head with Subaru BRZ

It's a battle that's been in the making for some time now: the Subaru BRZ versus the Mazda MX-5 Miata. And now that the new Miata has arrived – and in Club spec to boot – that's exactly what Motor Trend has lined up for its latest episode of Head 2 Head. Now before you go screaming that one's a coupe and the other a convertible, take a few commonalities into account. Roofs aside, both feature a 2.0-liter four mounted up front, driving the rear wheels through a six-speed manual transmission. Both are made by Japanese automakers and cost around $25-30k, give or take. Both produce around the same amount of torque, and while the Subaru may be more powerful, the Mazda's considerably lighter. To create a more even contest, then, you'd have to line a BRZ up against a Scion FR-S, or the MX-5 against the upcoming Fiat version of the same. Of course, being that close on paper doesn't mean that it's a draw. One has to come out on top. And after taking both along country roads and the Streets of Willow racing circuit, our friends at MT have picked one over the other. You'll want to watch the 22-minute video above (or at least skip ahead to the end) to see which came out on top, but if you're as enthused by a purist driver's car as we are, you'll enjoy every minute of it.
