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.

Mazdaspeed3 concept tipped for Frankfurt debut

The last quarter of 2015 could be a big one for Mazda as a report has emerged from Australia claiming that the company will come to the Frankfurt Motor Show in September with a near-production concept of the third-generation Mazdaspeed3, while a second-generation CX-9 will be shown a few months later in Los Angeles. Motoring.com.au ran the initial report, and although the news seems plausible, the outlet doesn't provide sources for either piece of news. Likewise, our friends at Mazda USA refused to comment on "speculation." Speculation it may be, but it's surely tantalizing considering the recent popularity of both the hot hatch and three-row crossover segments. According to the Aussies, the concept Speed3 will quickly evolve into a production model, which will launch alongside a mid-cycle refresh for the current 3. A turbocharged 2.5-liter will spit out 295 horsepower, and could have all-wheel drive. Even if only the front axle is doing the work, the MS3 will easily be able to stand toe-to-toe with hotter half of the segment based on output alone. As for the more mundane offerings, Motoring reports the long-in-the-tooth CX-9 will get a replacement in LA, although it doesn't offer much in the way of details beyond that. It should be interesting to see how the company's Skyactiv philosophy will be implemented on such a large vehicle. Perhaps the biggest surprise from the Australian report, though, are the outlet's reports on the CX-7, which will return sporting a third row of seats after its larger sibling debuts. That'd give Mazda a versatile lineup of four crossovers, with the sub-compact CX-3, the compact CX-5, the midsize, seven-passenger CX-7 and the fullsize CX-9. As we weren't able to confirm any of this with Mazda, we'd still warn that this news should be ingested with grains of salt. Still, it looks like the company could be set to make some waves in the first two shows of the upcoming auto show season.

Watch a high-speed chase from a motorcycle-mounted officer's point of view

Riding a motorcycle through high traffic can be a stressful experience. And we don't even want to imagine what it's like to have to actually pursue someone on a motorcycle. Fortunately, we don't have to. Officer Troy Gurley of the Florence, Alabama police force recently attempted to stop a vehicle for traffic violations. The driver, 24-year-old Justin Sanders, figured he could use his Mazda3 to outrun the bike cop. Turns out, not so much.
Gurley pursued Sanders for nearly five minutes as the Mazda driver ran stop signs, swerved through traffic and raced through residential neighborhoods, but the perpetrator couldn't shake the tenacious and experienced rider. Other units soon joined the pursuit, and Sanders thought it best to leave the protection of his car to attempt to flee on foot. From there, it didn't take officers long to apprehend him. You can watch the video below for yourself.
