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 planning more powerful MX-5?

The new Mazda MX-5 will be available with a 1.5-liter four with 129 horsepower or 2.0-liter with 155. And while either engine may seem a tad on the small side for a sports car, they keep perfectly in line with what the Miata is all about. That doesn't mean, however, that more powerful options aren't under consideration. Speaking with Motoring.com.au at the launch of the new MX-5, Mazda's global PR chief Kudo Hidetoshi revealed that two options are under consideration. One would be a larger engine, and the other a turbocharged version of the existing 2.0. The former option would deliver the extra punch while keeping things naturally aspirated and free from turbo lag, but could throw off the weight balance Mazda has worked so hard to preserve. The more likely option, then, would be the turbocharged route that would allow the Zoom-Zoom brand to keep the roadster light and nimble, while still delivering an extra boost. Neither would be without its challenges, but if overcome, the resulting high-performance model could be sold as a Mazdaspeed model in some markets and as an MPS version in others. And, even if such a performance roadster were to get the go-ahead for production in some markets, there's no guarantee that it will be sold in the United States. Here's hoping. Related Video:

Mazda5 will officially die this year

We knew it was coming, but it just became a lot more official. Mazda is going to kill the closest thing to a driver-oriented people-mover when it phases out the Mazda5 MPV for model year 2016. The news was presented quietly and unremarkably, with Mazda giving its compact minivan a single-line obituary as part of an announcement recapping changes to the brand's lineup for 2016: "There are no plans at this time to bring a replacement Mazda5 to the US market beyond the 2015 model year." Despite being a critical favorite for its fun-to-drive nature and seven-seat capacity, the 5 never really resonated with consumers, representing a small percentage of Mazda's total sales. In its best sales year, 2008, only about 22,000 were sold, representing only about eight percent of the brand's sales that year. That percentage was even smaller in recent years, as the 5's sales fell into the low ten-thousands. In other Mazda news, the brand is making a number of small, subtle changes to its lineup. Almost all of them constitute new ore removed options and are available for your perusal in the attached press release. Scroll down for a look. 2016 MAZDA LINEUP: WHAT'S NEW Having launched two refreshed and two all-new models for the 2016 model year, Mazda North American Operations is keeping busy with broadening its award-winning lineup of cars and crossovers. For the 2016 model year, Mazda is keen to maintain its leadership in providing unmatched KODO—Soul of Motion design and excellent driving dynamics and democratizing advanced safety technologies like Mazda Radar Cruise Control and Smart Brake Support into even its smallest, most affordable vehicles. Mazda6 and CX-5 return for 2016 with new styling elements, interior amenities and refinement. Mazda CX-3 enters the North American market in a new, hot segment, and MX-5 Miata continues its mission to provide unadulterated driving thrills to the masses. Last but not least, Mazda3 has been repackaged for 2016. Below is a list of what's new and different with Mazda's 2016 lineup.
