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:

2016 Mazda CX-9 starts at $32,420 with standard turbo engine

The 2016 Mazda CX-9 will start at $32,420 (including $900 for destination) when it arrives at dealers later this spring. The base price is just slightly higher than competitors in the three-row CUV segment like the 2016 Ford Explorer for $31,995 and 2016 Honda Pilot for $31,045. The new model is also more expensive than the 2015 CX-9, which had a $30,865 starting price. All versions of the 2016 CX-9 use Mazda's new 2.5-liter turbocharged engine with 250 horsepower (on 93-octane fuel) and 310 pound-feet of torque, which routes through a six-speed automatic. The combo returns an EPA-estimated 22 miles per gallon city, 28 mpg highway, and 25 mpg combined in front-wheel-drive form. All-wheel drive adds $1,800 to the price of most trims. We found the powertrain to be fantastic during when driving the CX-9 prototype. Even the base CX-9 Sport trim has amenities like LED headlights and taillights, a backup camera, trailer stability assist, and a seven-inch infotainment system. An optional Sport Package for $950 adds a power driver's seat, heated front seats, and heated side mirrors. Customers can really load the CX-9 with tech, though. The Touring model for $36,870 has Blind Spot Monitoring with Rear Cross-Traffic Alert, keyless entry, a power hatch, and an eight-inch infotainment system. The optional Touring Premium Package for $1,745 also adds automatic headlights, LED fog lights, navigation, and Smart City Brake Support. If that's not enough, the Grand Touring for $41,070 features a head-up display, lane-departure warning, lane-keep assist, and radar cruise control. The top spec CX-9 Signature for $44,915 includes all of these features and comes standard with all-wheel drive. It also has Nappa leather upholstery, rosewood trim, LED lighting around the gearshift, and LED accents on the grille.

2019 Mazda CX-3 crossover updated with a tad more power and refinement

NEW YORK — Mazda's smallest vehicle, the CX-3 subcompact crossover, is getting a refresh for the 2019 model year. Visually, you'd be hard-pressed to tell what changed, and that's because not much did. The grille now has slats that are grouped in pairs, and the rear taillights have been redesigned. But there are a number of changes aside from visuals that separate this model from the 2018. Under the hood is still a 2.0-liter naturally aspirated four-cylinder engine. It picks up two more horsepower and pound-feet of torque for totals of 148 for each, though Mazda says that it also picks up torque across more of the rev band and gets better fuel economy. Mazda didn't have official mileage numbers, though. The CX-3 will also now come with the G-Vectoring Control system that helps improve turn-in by reducing torque and shifting weight forward. The steering and suspension have been slightly retuned, and the tires developed to better absorb bumps. Deeper inside the CX-3, several changes should make the driving experience more calm and refined. These include thicker door panels and rear door glass to make things quieter. The seats are now wider with redesigned foam cushions for greater comfort. A new integrated armrest in the center console and one in the rear seats with cup holders help the same cause. Mazda will also add faux suede trim to the cabins of CX-3s for a more premium feel. Pricing hasn't been announced for the new CX-3, but the little crossover will go on sale in late spring. So expect pricing to come soon. Fuel economy numbers will likely be available soon, too. Related Video:
