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.

Even Ferrari swept up in latest Takata recall expansion

The scope of Takata's deadly airbag problems continues to widen. Eight manufacturers announced recalls Friday that affect more than 12 million vehicles, according to documents filed with federal regulators. The automakers include Honda, which is recalling 4.5 million units, Fiat Chrysler with 4.3 million, Toyota with 1.65 million, and Subaru, which is recalling almost 400,000. Some of these cars include the Saab 9-2x and Pontiac Vibe that Toyota and Subaru made for General Motors. Mazda will recall 730,000 vehicles and Nissan has 400,000 affected units. The smallest numbers were posted by Mitsubishi, with 38,000 Lancers manufactured from 2006 to 2007, and as a noteworthy high-end manufacturer, Ferrari is calling back 2,800 vehicles. These are all US-market cars. Beyond America, the Japanese Transport Ministry has announced seven million additional vehicles will be recalled, which means 19.6 million vehicles across the globe are affected by recalls announced. The defects have been traced to an insufficiently manufactured airbag inflator, which lacks a drying agent that would prevent the inflators from deteriorating over time. Thirteen deaths have been linked to the faulty airbags, which have become unstable and are prone to exploding and showering vehicle occupants with lethal amounts of metal shrapnel. A private equity firm, KKR & Co., has been named in a possible buyout of the struggling Takata.

Mazda RX-7 could return in 2020

We like writing about the next Mazda RX-7 because it's like writing about the Chupacabra, Slenderman, or the Florida Skunkape, all of which are imaginary creatures seen by someone who knew someone who had an uncle whose dead great-grandfather's sister took a picture of it, invariably at night, while she was drunk, with her 1933 Kodak Brownie. Autocar is the latest with an RX-7 revival, saying it could come as soon as 2020 to celebrate Mazda's 100th anniversary. Before we get to that, let's take a brief look at RX-7 rumors. In 2009 there was speculation we'd get a concept RX-7 at the Tokyo Motor Show. That same year it was predicted the RX-8 would die to make room for a new RX-7 in 2012. In 2010 Mazda was developing a 300-horsepower rotary for the RX-7 that could run on gasoline or diesel and had better fuel economy and less oil consumption. Then Autocar said we could get the new RX-7 by 2013, a rumor that turned into a new RX-9 based on the Mazda MX-5 Miata platform. In 2012 the potential arrival date had become 2017. In 2013 the company CEO Masamichi Kogai said the equivalent of "Not gonna happen," and he said it again last year, just 90 days ago. It should be clear by now that this car is Mazda's version of the Lotus Esprit. Whew. Now that we're clear on all that, what does Autocar say? That a follow-up to the extinct RX-8 is coming that will sit on the new MX-5 Miata platform, and Mazda's vice president of European R&D said there are still 30 engineers working on rotary engines in partnership with universities. The successor will be front-engined and rear-wheel drive, have either two seats or 2+2 seating, and could be called RX-6, RX-7, or RX-9. That sounds like three distinct statements, only one of which is definitely true, that could possibly just maybe add up to a new RX-7, but could even more likely add up to a rotary-engined concept car that never sees production. We've only got five more years to wait, and since we've been begging at the RX-7 doors this long...
