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:

Mazda zooms into SEMA 2016 with lighter MX-5 Speedster and RF Kuro concepts

It's almost time for the 2016 SEMA aftermarket show again, if you haven't guessed already by the steady parade of early looks at various show cars. Mazda's MX-5 creations are generally a highlight for us, unapologetic Miata junkies that we are. This year's cars should be just as exciting as last year's, one being a revision of last year's Speedster concept and the other based on the brand new, sexy RF retractable targa top model. Both SEMA MX-5s were designed and built in-house at Mazda's Irvine design studio. This year's Speedster is somehow even lighter than before. Mazda carved 100 pounds out of it, making it a staggering 350 pounds less than a production soft top model. It's also been repainted in a color called "White Ether", which we're imagining looks something like the "Blue Ether" paintjob on last year's highly reflective Speedster minus the blue tint. Mazda will probably never sell a roofless Miata or anything this lightweight, but maybe it should. It looks like it'd be a blast to drive at a road course. And then there's the RF Kuro concept, the first RF-based SEMA show car, which is shown in the teaser above. It doesn't seem terribly extreme, to be honest. It's wearing a matte charcoal paint, which explains the "Kuro" moniker – kuro means "charcoal" in Japanese. A set of 17-inch RAYS forged wheels and MX-5 Cup suspension, and that's about it. Not to knock it; the RF is a sexy looking thing as it sits, and Cup suspension should make it handle even more like a go-kart. Of course, both concepts will be fully revealed at the show next month in Las Vegas. Stay tuned for a dose of concept Miata hotness.Related Video:

2020 Mazda MX-5 Miata due for price bump, more safety tech

Mazda hasn’t released official information yet on its 2020 MX-5 Miata, but CarsDirect got its hands on an early draft of an order guide, which suggests both the soft- and hard-top versions of the roadster are due for a price bump after receiving more standard safety technology and some suspension upgrades on certain manual models. Starting price on the 2020 Miata Sport Soft-Top will be $26,580, not including destination, which is reportedly not yet listed, according to the report. ThatÂ’s $850 above the non-inclusive 2019 base price. The price hike on the Grand Touring trim is even higher, at $1,090. For the RF Club Hardtop, starting price inches up by $700 to $33,045 — again, excluding destination, which was $895 for 2019. If you want to drive stick, prepare to pay more for the Grand Touring manual versions, which will climb by $890 and $1,090 for the soft- and hard-top versions, respectively. ThatÂ’s down to new Bilstein shocks, a limited-slip differential, front shock tower braces and a sport-tuned suspension, which should make for fun driving for stick enthusiasts. The big news is that the i-Activesense suite of safety technologies, previously offered as a package, will go standard across all trim levels. It features lane departure warning, blind-spot monitoring, rear cross-traffic alert and low-speed automated braking. Apple CarPlay and Android Auto will also reportedly debut on both versions of the roadster as standard on Club trims and above. The Miata is already coming off a 2019 when it got an infusion of 26 more ponies and 3 pound-feet, bringing output to 181 hp and 151 lb-ft from its 2.0-liter Skyactiv-G inline-four engine, plus that limited-edition 30th Anniversary model. Looking ahead, Mazda is reportedly toying with the idea of electrifying its lightweight roadster for its next generation, expected mid-next decade. Related Video:
