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:

Leaked images show digital gauge cluster for Mazda3

Most everything divulged about the 2019 Mazda3 so far has focused on the trick Spark Controlled Compression Ignition (SPCCI) Skyactiv-X engine. If a series of photos posted on a Chinese website are accurate, it looks like Mazda has novel plans for the cockpit as well. The three images show a three-color, all-digital gauge cluster in two different configurations. The first configuration places a three-digit speedo in the center of a blue-ringed tachometer, with gear indicator and water temp displays on the left, fuel range calculator and what appears to be a funky clock on the right. The second configuration splits the tachometer to the left and the speedo to the right. In between them is what looks like a road surface display for automatic cruise control. Trip info lies just under the blue-banded road, while water temp, fuel gauge, gear indicator and range info line up across the bottom. A swath of empty space on the left could be where Mazda's relocated the current car's passel of warning signals. Of note: Everything around the digital gauges appears to come straight from the current Mazda3. The instrument panel surround, the steering wheel and buttons, the stalks, all of it is lifted from today's car. If the photos are what's headed our way on some trim of the 2019 Mazda3, though, they show a clean, handsome evolution of the no-nonsense cluster in the current compact hatch. Mazda's worked up a head of good press on the run-up to the Mazda3 launch for both the engine and the dynamics. We're told we'll get between 10 and 30 percent more torque from the 2.0-liter SPCCI Skyactiv-X, and about 25 percent better fuel economy compared to today's 2.0-liter Skyactiv-G. Handling-wise, the jinba ittai philosophy — horse and rider as one — has led to engineers reworking everything from tire sidewall stiffness to multi-contoured torsion elements and the mounting and shape of the seats. The hatchback's torsional stiffness climbs by 30 percent, any excess rigidity countered by 7.5 meters of "matrix resin material" applied in 16 places on the body "to absorb vibration and dissipate it as heat." The point has been to eliminate dynamic static between the driver and the road, and then to give the driver the best natural seating position to take advantage of the body's reflexes to dynamic input. At the same time, this digital gauge cluster might also give that driver something tasty to look at. Related Video:

30th Anniversary Mazda MX-5 Miata sells out immediately

Remember back in 2014, when Mazda released the 25th Anniversary Mazda MX-5 Miata and it sold out in 10 minutes? Now, just hours ago at the Chicago Auto Show, Mazda opened the books for the 30th Anniversary model — and you guessed right, it's now sold out as well. This time around, it took four hours, but there's a difference: in 2014, there only were 100 25th Anniversary cars to pre-order, and for the big 3-0, Mazda allocated 500 U.S. cars. We're expecting the 2,500 rest-of-the-world cars will also sell out rather quickly. The 25th Anniversary model was Soul Red, but in the lighting seen in the 2014 article it rather reminds us of the "Sunkist" orange of the original NA generation Miata color test car, the orange one out of six one-off special paint cars. This year's model is more clearly orange, a hue Mazda calls "Racing Orange" and says it's inspired by the 1989 Club Racer concept's ... bright yellow. In any case, it's a good match with the ND's swoopy flanks. There is — we mean, was — a choice of regular Roadster from $34,995 and the folding top RF version from $37,995, and a choice of manual or automatic transmission. It took a refundable $500 deposit to secure one of the 500 cars. Chicago Auto Show Mazda
