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.

Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
Take a look and let us know what you think in Comments.

2016 Mazda MX-5 Miata battles Toyota GT86 on track

It's got two doors and a 2.0-liter four-cylinder engine up front, driving the rear wheels. It's made in Japan, and as far as bang-for-your-buck goes, it's a downright bargain. So which are we talking about, the Mazda MX-5 Miata, or the Toyobaru coupe known alternately as the Subaru BRZ, Scion FR-S, or Toyota GT-86? The answer is "yes," and it just goes to show, roofs notwithstanding, how close these two vehicles really are to one another. Which one is your favorite may come down to a matter of personal taste, but for its latest video, Auto Express set out to find out which laps faster around the track. On paper at least, the Toyota's 200 horsepower will trump the Mazda's 155 any day of the week, and twice on Sunday. Then again, the Miata does weigh a good 400 pounds less, even with the 2.0-liter engine and despite its convertible bodystyle – but is that enough to make up the difference? You're going to have to just watch the video for yourself to find out. All we'll tell you is that the match is pretty darn close – what you might call a photo finish, if they were actually racing each other at the same time as opposed to each racing the clock separately. So watch the video above and voice your support for your favorite little Japanese sports car in the Comments section. Related Video:
