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.

2019 Mazda MX-5 Miata may be getting 181 hp

Even though the current 2018 Mazda MX-5 Miata makes only 155 horsepower, our experience has shown that it's more than enough fun with its modest output. Still, if Mazda were to offer more, we wouldn't turn it down, and it appears that's exactly what will happen for the 2019 Mazda MX-5 Miata. Road & Track dug up a VIN filing from Mazda to NHTSA with information about the Miata for that model year. On one of the pages, it states that the 2019 Miata will have a 2.0-liter four-cylinder making 181 net brake horsepower. That's a pretty big jump from 155 horsepower, nearly matching the larger 2.5-liter engine in the Mazda3 and Mazda6. It's also close in power to the estimates for the Skyactiv-X spark-controlled compression-ignition engine. But, based on what a journalist on Twitter posted, the 2019 Miata will continue to use a version of the existing spark-ignition Skyactiv-G engine. Apparently it will have a new cylinder head, be able to rev higher, and make more horsepower, though he didn't say how much more. This content is hosted by a third party.

We've reached out to Mazda for comment on this discovery, and, like with most car companies, wouldn't give comment since the topic regards a future product. If it does turn out that Mazda won't up the horsepower for 2019, the good news is that the aftermarket has speed demons covered. Flyin' Miata offers a package that includes camshafts, exhaust and a tune that will bring it up to about 200 hp. There's a supercharger kit from Edelbrock that will provide similar power, but without the need for digging into the engine. Flyin' Miata also offers a turbocharger kit that can bring the Miata up to nearly 250 hp, and if you're really speed-crazed, the company can swap in a Chevy LS V8 with more than 500 hp. Or, you know, you could just be happy with 155. Related Video: Featured Gallery 2016 Mazda MX-5 Miata Club View 32 Photos News Source: Road & Track, Twitter Mazda Convertible Coupe Performance

A pair of Mitsubishis, the Mazda CX-30 and electric incentives | Autoblog Podcast #673

This week's Autoblog Podcast features Editor-in-Chief Greg Migliore and Consumer Editor Jeremy Korzeniewski as they debate the merits of the redesigned Subaru BRZ and Toyota 86 coupes and whether or not they are distinctive and powerful enough to attract buyers. The duo spends some time discussing ongoing EV and infrastructure legislation before turning their attention to a trio of crossovers. Greg muses about the 2021 Mazda CX-30 before Jeremy talks about the refreshed 2022 Mitsubishi Eclipse Cross and completely redesigned Outlander. We get nostalgic as we remember the dearly departed Pontiac GTO before wrapping the podcast up by making one more suggestion to a longtime listener who is shopping for a vehicle to replace her aging Honda Pilot.
