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.

Mazda Miata 'fathers' Hall and Case offer a tour through the roadster's history

The original Mazda Miata broke onto the automotive scene in 1989 and was a huge success. However, the convertible's genesis goes all the way back to the early '80s. Bob Hall and Dean Case were among the inside men of the program on the US side, and they were on hand at Mazda Raceway Laguna Seca during the recent MX-5 event there to tell some of their stories about the project's beginning.
Hall was on the Miata project from very early on, and one of his most fascinating stories is how the convertible got its shape. The droptop wasn't necessarily going to be a rear-wheel drive roadster. There were both front-wheel-drive coupe and mid-engine concepts being considered. In fact, the classic look of the NA generation was the least favorite of the three at the sketch stage.
Hall comes off as a jokester hiding a genius mind. He has a fountain of information in his head about what a Miata should be, but it all comes down to "less is more." However, he admits that it's easy to conceive that idea, but it's much harder to actually execute it well.

Toyota, Honda, Mazda and Nissan recall 3.4 million vehicles for faulty airbags

Most vehicle recalls that take place these days are a result of some problem that happens during the manufacturing process by the automaker, but as we see here, parts suppliers can also factor in to problematic safety issues. Automotive News is reporting that a total of 3.4 million vehicles produced by Japanese automakers between 2000 and 2004 are being recalled globally due to faulty airbags produced by an outside supplier, Takata Corp.
According to the report, vehicles from Toyota, Honda, Nissan and Mazda are being recalled because of passenger front airbags that do not inflate properly. Globally, Toyota is said to be recalling around 1.73 million cars including 510,000 in the US composed of Toyota Corolla, Matrix, Sequoia and Tundra as well as the Lexus SC430 for the 2001 through 2003 model years; this is the second time this year the 2003 Corolla and Matrix have been recalled for an airbag problem. Honda is recalling 1.14 million models, Nissan another 480,000 and Mazda 45,463. The article says that Takata supplied faulty airbags to non-Japanese automakers, but it did not specify which ones.
Honda and Toyota have released information on their own websites about the recall, while Nissan and Mazda have not yet commented. Read official press releases from Honda and Toyota, below, and look for updates as we have word from the others.
