Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

2018 Mazda MX-5 Miata finally has a great pair of seats

We all know the 2018 Mazda MX-5 Miata is a truly wonderful car. It takes everything delightful about cars and driving and distills it into a compact and lightweight package. It's a car anyone can enjoy. My wife, who until recently has shown no real interest in sports cars beyond their design, wants one. I want one, too, but I couldn't get past the Miata's terrible seats. For 2018, there's finally an alternative. The 2018 Miata got a number of minor updates. Most people I know were fawning over the new cherry-red top, but I was far more interested in the leather-wrapped Recaro seats. These are now included in the $3,770 Brembo/BBS package. Previously, that package just added a set of two-piston Brembo front brakes and black BBS wheels. Having put thousands and thousands of miles on various NDs, I didn't think it was really a worthwhile option unless you were planning to track the car regularly. These seats have changed my tune. The standard seats in the Miata are bad when new and get progressively worse as they break in. I'm a big guy (6-feet tall and about 220 lbs.), but I know I'm not alone in the assessment. They're thin, unsupportive and wrapped in some cheap fabric. Just look at this photo from our old long-termer. The seats kill any real desire to own one. These Recaros are different. Yes they're still thin, but they have bolstering and padding in all the right places. I no longer feel like I'm riding along on a cheap, worn-out couch. Plus, they're heated (though you can now get heated cloth seats), making the brisk Michigan-morning commute far more comfortable. Now all the Miata needs is a slight bump in power.

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:
