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:

2019 Mazda3 Sedan Drivers' Notes Review | Moving on up

The Mazda3 enters its fourth iteration for 2019, replacing one of our favorite compacts on the market. As such, expectations were high for the new model. Like before, the Mazda3 is available as both a sedan and hatchback, though the big news for the new model is the available all-wheel drive system, a rarity for the class and and a feature more and more people are looking for in a car these days. At launch, power comes solely from a 2.5-liter naturally aspirated inline-four, though Mazda plans to offer additional powertrains down the line. Competitors include the Honda Civic, Toyota Corolla, Subaru Impreza, Hyundai Elantra and Kia Forte. Our tester was a well-equipped Mazda3 Premium front-wheel-drive sedan. Standard features include 18-inch wheels, LED lighting, a power driver's seat, leather seating and trim, keyless entry and ignition, dual-zone climate control, an 8.8-inch infotainment system, Bose audio, blind-spot monitoring, rear cross-traffic alert and adaptive cruise control. The only added cost to the Premium Package is $595 for the paint. All in, our tester came out to $27,990. Editor-in-Chief Greg Migliore: The Mazda3 is the sportiest in the segment and, as far as I'm concerned, it's dead-even with the Honda Civic for the top spot in the looks department. The steering, brakes and suspension all feel dialed-in and quick. Many compacts are sedate. The 3 makes you want to track it. The suspension is stiff enough that non-enthusiasts might prefer something else, though it's not abusive. The naturally aspirated four provides just enough getup. Mazda is good at the minimalistic approach. Tune a car well, make it look sporty, and don't try to overcompensate with horsepower. This thing looks great inside and out. For the price, you can't beat it. The cabin has the appearance and feel of a premium sedan, with pleasing materials and an enveloping cockpit. With a creased hood and huge, blacked-out grille, the 3's front end has a contemporary style with old-school panache. I might like the hatch better because it's a rarer body style. Still, this sedan is a well-rounded, sporty execution and a great value. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Associate Editor Joel Stocksdale: Since its reveal at the Los Angeles Auto Show, the 2019 Mazda3 has been my most anticipated car of the year, as well as the one I've been most worried about.

Ever wonder how to really pronounce Japanese automaker names?

People tend to get very set in their ways when it comes to the pronunciation of words. Just look at the endless debates over whether or not to say the final 'e' in Porsche (which you should in terms of correct German enunciation). Or the argument about whether to follow the British convention and give the 'u' in Jaguar a special delivery or to say the 'ua' diphthong as more of a 'w' sound, as usually happens in the US.
This short video doesn't answer either of those automotive questions, but it does allow a native Japanese speaker to demonstrate the accepted pronunciations for several, major automakers from the country. One benefit is that it clears up the occasional debate over whether Nissan should be said with a long or short 'i' sound. Also, listen closely to how the female host says Mazda as Matsuda, the way it's actually said in the language. Even if this doesn't change the way you enunciate these brands, at least now you know the accurate way in Japanese.
