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:

First batch of 2016 Mazda MX-5 Miatas lands in US [w/video]

Have you been patiently awaiting the arrival of the all-new 2016 Mazda MX-5 Miata? Then we're glad to report that your patience has paid off. In fact, even if you haven't been so patient, we're still glad to report that the wait is finally over, as the first batch of the new Japanese roadsters has arrived on American soil. The initial batch of several hundred MX-5s arrived at the port of San Diego from the factory in Hiroshima on board the Phoenix Leader, a 636-foot vehicle carrier ship registered in Panama and operated by Japanese shipping giant NYK Lines. The vehicles are currently being processed at the SoCal port, with deliveries to commence "in the next several weeks," according to Mazda in the brief statement below. The fourth-generation Miata, designated generation ND, mad its global debut at the Paris Motor Show, and its US debut at the LA Auto Show. Production commenced in Japan this past March. The new roadster arrives in US showrooms with a 2.0-liter four-cylinder engine (the smaller 1.5 kept away from these shores), a six-speed manual (replacing the previous five-cogger), a folding soft roof (no retractable hard top this time), and a starting MSRP of $24,915 (plus an $820 destination charge). That, of course, is for the base Sport model, with higher-spec Club and Grand Touring trims also on offer. Along with the images above, you can watch footage of the vehicles driving off the ship in the video below. Might we recommend, however, muting the cheesy soundtrack and playing something more suitable over it instead. Neil Diamond's (Coming to) America ought to do the trick... today!

Refreshed 2017 Mazda 3 and 6 get G-Vectoring Control

Back in June, we told you about Mazda's G-Vectoring Control system, which is an additional layer of unobtrusive cornering assistance to help maintain traction at the limits of adhesion. It's subtle to the point of being hard for a human being to detect, even a Mazda engineer, as we found out driving a G-VC equipped Mazda 6 around Mazda Raceway Laguna Seca. We knew then that the G-VC system would make it to the 2017 Mazda 3 and 6, but now all the details of both mildly refreshed cars are available. Let's start with the Mazda 3, which has a few more changes than its larger stablemate. As is standard industry practice, a mild facelift includes available LED headlights and taillights, a new grille, and a monochrome rear bumper. Inside, the slightly recontoured steering wheel now has available heating and the manual handbrake has been replaced by an electronic one. Fans of handbrake turns will frown, but those handles take up an immense amount of room (relatively speaking) inside the center console. The redesigned center storage bin takes better advantage of that newly freed-up space. Lastly, Mazda claims the 3 is quieter thanks to improved insulation and weatherstripping. The Mazda 6 was just refreshed last year, so the list of changes is even shorter. The larger sedan benefits from similar sound-reducing tweaks as the 3, and the entry-level 6 with a manual transmission now comes with the Mazda Connect infotainment system, a real upgrade from the older non-touchscreen system. One thing that both share is an available full color head-up display, which replaces a functional but ancient-looking monochrome unit. If you've been in a Mazda currently on sale with this old-looking system, you'll really appreciate the way this new one looks. We can't wait to try it out. Both new Mazdas go on sale in September. Pricing isn't available at this time.
