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:

2014 Mazda3 Sedan

We're not going to beat around the bush: for the kind of person who willfully chooses to take longer, windier and more scenic routes to get to Point B, the 2014 Mazda3 is the new compact car measuring stick by which others will be judged. That doesn't, of course, make it the right choice for every buyer.
We'll spend the next thousand words or so explaining the whys and hows that make our opening statement a fact, but for now, suffice it to say that Mazda has engineered its latest crop of vehicles - namely the CX-5, Mazda6 and its smaller sibling and subject of this test, the Mazda3 - from the ground up. Absolutely everything about the Mazda3 is refined for 2014, from its chassis to its engines and everything in between, and it was done in a completely new and holistic way. Every component, subcomponent and stamping required to bolt and weld together an automobile was rethought to ensure the Mazda3 has what it takes to compete with such established benchmarks as the Honda Civic and Ford Focus.

2019 Mazda CX-5 debuts with turbocharged engine and near-$40K price tag

We've seen a couple different leaks concerning the 2019 Mazda CX-5, but now Mazda finally has official word on what's coming our way. One exciting development is the addition of the 2.5-liter turbocharged four-cylinder engine on higher trim levels. It's great to see Mazda sharing that engine to other models after originally debuting in the larger CX-9. In the CX-5, it makes 250 horsepower and 310 pound-feet of torque on 93 octane. To get the boosted engine, you'll have to opt for one of the two new trim levels Mazda has added for 2019: Grand Touring Reserve or Signature. Of course, with higher trim levels and more powerful engines come higher prices. The Signature trim comes in at a whopping $37,885 including destination charges. For 2018, the highest trim level available was the Grand Touring, and that car costs $30,640. Mazda adds a bunch of new features for the expensive Signature trim, though. You'll get brown leather seats, real wood trim, a uniquely stitched leather steering wheel, 360-degree view camera, a frameless auto-dimming mirror, LED lighting throughout the interior and dark silver 19-inch wheels. These options are in addition to the new and still luxurious Grand Touring Reserve trim level. This trim has heated and cooled seats, a heated steering wheel and power folding mirrors as its highlights. For comparison, the Grand Touring Reserve with the turbocharged engine costs $35,865. Making the CX-5 more luxurious wasn't the only aim for 2019 — Mazda also gave it a new version of its G-Vectoring Control handling system. The updated G-Vectoring (now called G-Vectoring Control Plus) helps when the driver is unwinding the wheel by "adding a hit of braking to the outside front wheel," according to Mazda. This, in addition to some suspension refinements, are supposed to make for a smoother and better ride. Specifically, Mazda says it re-tuned the suspension to reduce friction and adjusted the steering geometry to achieve more natural feeling handling. Sweating over these small handling and feel things is why we typically end up liking the driving experience of Mazda vehicles. Mazda increased prices on the CX-5 across the board, too. The Sport trim is $1,600 more than before, with other trims following suit at similar increases. We'll see how the changes affect the sporty and now more expensive crossover when we get our hands on a 2019 model. For now, you can build them on Mazda's website, and Mazda says they'll be available sometime this fall.
