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.

Alfa Romeo takes Spider in-house, Mazda-Fiat roadster partnership not dead

It's officially off. Following a report in March of this year that the marriage of Mazda and Alfa Romeo to produce a MX-5-based Spider was in trouble, the Italians have confirmed that it will take development in-house. "As far as the Spider goes, the final version is of course no longer the two-seater FCA co-developed with Mazda but a derivative of Project Giorgio," Maserati and Alfa Romeo brand boss Harald Wester told Car. For those not in the know, Project Giorgio is Alfa's codename for the rear-drive platform that will underpin the next-generation Spider, not to mention the replacement for the 159 sedan and a few other products. All is not lost for the Japanese-Italian partnership, though. "The Far East import will probably find a new home with Fiat-Abarth," Wester told Car. Yes, you read that correctly, Mazda is still working with FCA, and the result will eventually end up with Abarth's scorpion badge. If anything, we're more excited over this news than the idea of an Alfa MX-5. But we want to know what you think – would you rather Alfa build a new Spider on the Miata's bones, or does an MX-5 Abarth sound like more fun? Have your say in Comments.

Mazda is developing gas and diesel inline-six engines

Once the favored engine configuration for luxury and high-performance cars, the inline-six suffered a bit when the transverse (east-west) engine configuration became popular during the shift to front-wheel drive cars. The packaging benefits are obvious – no driveshaft or transmission intruding on passenger space or rear differential on cargo volume, plus turning the engine 90 degrees meant the front of the car could be shorter. But the inline-six is slowly, slowly crawling out of near-obsolescence, notably in BMW, Jaguar-Land Rover and Mercedes-Benz products. Add Mazda to that mix: An investor report first spotted by Jalopnik and confirmed by Mazda reveals that the company is developing a Skyactiv-X and Skyactiv-D inline-six that will be installed longitudinally (north-south) in a new "Large Architecture" platform. Before reading any further, let's catch up on the Skyactiv-X and -D technologies. The former basically burns gasoline like diesel, providing some benefits and advantages of both types of combustion - here's an explainer on how that all works. We drove a prototype 2.0-liter Skyactiv-X 4-cylinder engine in a Mazda3 mule, too. And the Skyactiv-D series of engines is a comparatively typical turbodiesel. Mazda has a 2.2-liter turbodiesel inline-4 that has had a long and convoluted development and certification process, but is finally showing up in the 2019 CX-5. Since Mazda has implemented these technologies in existing four-cylinder engines, we would assume that the new Skyactiv engines will be "modular" – that is to say, they'll essentially be the existing engines with two extra cylinders, rather than an entirely new design. Jaguar-Land Rover is doing a similar thing with its Ingenium engine family. Assuming the Mazda engines will be modular would mean they'll be roughly 3.0-liter units, which is a common displacement for modern inline-sixes. And as we mentioned eariler, they'll be arranged longitudinally, unlike any other Mazda save the MX-5 Miata (and the long-departed rotaries), in a new vehicle architecture. As part of a medium-term plan over the next six years, Mazda will develop some unspecified vehicles on what it calls the "Large Architecture". These vehicles will have 48V mild hybrid and PHEV capabilities, and be able to use a version of Mazda's i-Activ AWD system. Why do this at all?
