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.

Will the new Mazda Miata be available with multiple engines?

At this point, the countdown until the launch of the all-new, fourth-generation 2016 Mazda MX-5 Miata can be measured in hours until its September 3 unveiling as easily as it can in days. With the debut of such a highly anticipated model so close, the rumors about the new sports car are starting to boil over.
We recently heard that the new Miata would likely get a 2.0-liter Skyactiv four-cylinder with a six-speed manual, plus a decent drop in weight compared to the current gen. There's even the rumored possibility of a fastback coupe version sometime in the future.
Now, Australia's GoAuto is adding another dollop of speculation into the mix with the claim that there could be "potentially more engine options," according to Mazda Australia managing director Martin Benders to the website. The more potent option would still be the 2.0-liter Skyactiv with a power bump from its current 167 hp to closer to 200 ponies. The other possible powerplant option would be a 1.5-liter, naturally aspirated four-cylinder taken from the upcoming Mazda2 replacement. This version would also ditch some of the MX-5's more premium features to cut the weight and the price slightly.

Mazdaspeed2 supermini hot hatch under consideration

Though the Ford Fiesta ST and Fiat 500 Abarth (and arguably the Mini Cooper S) may stand pretty much alone in the North American market, in overseas markets, supermini hot hatches are a big deal. Unfortunately, challengers like the Volkswagen Polo GTI, Seat Ibiza Cupra and Renault Clio RS 200 Turbo never make it to our showrooms, but word has it that there's soon to be a new entry on the market.
That would be the Mazdaspeed2, which would be badged in certain markets as the Mazda2 MPS. Speaking with Australian site CarAdvice.com.au at the launch of the Mazda2 on which it would be based, the Japanese automaker's global sales chief and the hatchback's deputy product manager hinted that such a product is definitely being discussed, even if it hasn't yet been approved.
This wouldn't be the first time such a notion were entertained, as Mazda has shown numerous performance concepts based on the previous Mazda2/Demio over the years, but none have come to fruition.
