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.

2016 Mazda2 won't come to the US

Hoping to get your hands on the new Mazda2? Don't get your hopes up too high, because the latest word has it that the new hatchback won't be available in the United States. According to the report from Automotive News, Mazda's US office has decided against bringing the new Mazda2 to American showrooms. This despite it being made just south of the border in Salamanca, Mexico. The reasons are apparently two-fold. For starters, Mazda sales offices around the world have been clamoring for larger allotments of the new 2, and the company can only supply so many. "We could have had it, but we would have had a number that didn't make much sense with 600 dealers and with the marketing it takes to launch a new car," Robert Davis, Mazda's senior VP of US sales operations, told AN. For another, Mazda is apparently not convinced the new supermini would resonate with US buyers, who are increasingly migrating towards crossovers. So Mazda is focusing instead on "products that make us and our dealers considerably more profit than a Mazda2 does." That doesn't mean the latest Mazda2 will be entirely out of our reach forever, though. The company's agreement with Toyota will see a sedan version sold in the US as the Scion iA. Mazda is also certifying it to US safety and environmental standards so that it can sell the 2 in Puerto Rico, which means that it wouldn't take much to change course and bring the hatchback into the US in the future: "It'll always be there if we need it," Davis told AN. Reached for comment, a spokesman for Mazda's North American operations told Autoblog that "The Mazda2 launch in the U.S. market is on hold in order to evaluate the B-Car segment and enable us the opportunity to focus on the launches of the refreshed Mazda6 and CX-5, and the all-new MX-5 roadster and CX-3 subcompact crossover SUV." That leaves the aforementioned CX-3 - which is, incidentally, based on the same architecture as the Mazda2 - as the smallest mainstream model that Mazda will offer Stateside.

Road & Track to take Miata on million-mile march

Road & Track has taken on a Miata project. One hell of a project, if we're honest. You see, the Miata in question, a 1989 example in Mariner Blue, isn't a high-mileage Mazda that the publication intends to fix up, or make race-worthy, or try to flip or give away to a reader or something. No, it's a rather typical well-used NA, with a hefty 325,000 miles on the clock to-date that the staff plans on driving until the six-digit odo reads all zeros again. One million miles or bust (or both, most likely).
Procured for the bargain-basement price of $1,600, complete with seat covers that "really do look like muppet pelts" (according to Zach Bowman) and a bondo-filled love tap on the nose, the NA Miata actually looks like just the sort of fun-machine that a real driving enthusiast would pick up to get some cheap thrills in. The R&T team already has some interesting plans for the Miata, including a potential run up Pikes Peak and loaning it out to readers (or perhaps your author...). Click through to read all about it.
