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:

Are you the 2016 Mazda Miata?

Tech nerds are spoiled. Every year, there's a new iPhone that arrives following months and months of breathless speculation and rumormongering. We car folk have a more difficult life, because vehicles with the iPhone's cult-like devotion and following, while plentiful, only receive hefty updates after several years. Case in point, the Mazda MX-5.
There's a new one coming, and much like the iPhone 6, it'll arrive in just a few weeks. So, in lockstep with the tech folk, we're anxiously biding our time and waiting with baited breath for the expected debut date of September 3. Also, like Apple fanboys, we're clamoring over any hint or teaser as to what the next-gen Miata will bring, which is why we're showing you the above image.
That is, allegedly, the new MX-5 hiding under the sheet. Auto Motor und Sport has the image, which according to World Car Fans was released by Mazda. Of course, we've reached out to the Zoom-Zoom brand for verification of its authenticity, and will be sure to update as soon as we hear back.

2018 Mazda3 gets low-speed automatic braking across the board

Though the Mazda3 is mostly carry-over for the 2018 model year, Mazda has sweetened the deal on all trim levels ever so slightly with more standard equipment. Most notable is the inclusion of low-speed automatic emergency braking on the base Sport trim. That makes the feature standard on every version of Mazda3, and it's also included on manual transmission models. Touring's big change is the inclusion of the 184-horsepower 2.5-liter engine as the standard powertrain. This means you'll only be able to get the 2.0-liter engine on the Sport trim. Finally, Grand Touring gets a lighting upgrade with self-leveling LED lights up front along with LED taillights and running lights. Mazda also supplies these additional features while barely changing prices. The Sport trim level increases by $250. The Touring trim actually drops in price by $355 for the sedan, and an impressive $1,555 for the hatchback (when compared with the existing Touring 2.5 trim level). Grand Touring pricing remains the same as the 2017 model year. Related Video:
