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.

MotoMan at Targa Newfoundland, Part Two

MotoMan at Targa Newfoundland Part 2

The crew at MotoMan has rolled out the second episode of its Targa Newfoundland coverage. This time around, Brandon Fitch and I spend plenty of time talking with the guys about the challenges of Day One, how the Flyin’ Miata supercharged NC MX-5 Miata handles some of the more technical stages and joy of hauling ass through a subdivision. Meanwhile, team MotoMan gets a few valuable lessons on competition in targa from veterans of the race like Rob Pacione and learns a little about Newfoundland hospitality at the same time. As the week continues, competitors are forced to overcome a variety of challenges, from an entire engine swap in a Lotus to a water-logged 911.

Part Two gives us all a better idea of what it’s like to compete in Grand Touring, where the goal is to hit a specific time and speed, rather than simply beat a time like in Targa class. Both competitions are challenging in their own right, but we have to sympathize with MotoMan’s frustration at being forced to limp a Dodge Challenger 392 along at 40 miles per hour with an open road ahead of you. Scroll down to check it out for yourself.
