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:

Updated Mazda3 hits US roads this year

Mazda released an updated variant of its Mazda3 that will go on sale in Japan today and later this year in the US. The compact vehicle benefits from Mazda's G-Vectoring Control (GVC) that provides integrated control of the vehicle's engine, chassis, transmission, and body. The result, from our own experience, results in a car that's more enjoyable to drive. GVC is the first feature in a series of new Skyactiv Vehicle Dynamics technologies. Mazda is developing them to provide drivers with greater feel and a more enjoyable experience. "Mazda is striving to become an irreplaceable presence in the lives of our customers, to create a special bond with them and to be a 'one-and-only' brand they will chose again and again," Mazda's CEO Masamichi Kogai said in a statement. Other than the new feature, the 2017 Mazda3 goes mostly unchanged with the front end gaining slimmer turn signals and fog lights. The current-gen lineup, claims Mazda, is centered around Jinba Ittai – a term the automaker uses to signify oneness between car and driver – that started with the launch of the Mazda CX-5. The updated Mazda3 will go on sale later this year in the US, but the automaker did not announce an official date.

Chicago Auto Show: The really big reveals from shows past

The 2024 Chicago Auto Show may seem like a shell of its former self, but it still holds the title of the largest consumer auto show in the United States. It didn't get that reputation simply by being efficiently produced or convenient for locals desperate for something to do in February — it earned it over decades of breaking automotive news and powerhouse reveals, eventually earning an informal designation as America's truck show.  2024 may be a down year for Chicago, but let's not forget all of the great things that have come out of it, historically. Here's a look at some of our staff favorites. Bet you didn't know about a few of these cars that were first revealed in the Windy City.    2008 Dodge Challenger SRT-8  I didn't just pick this one as a former Challenger owner, but instead to illustrate just how many cool Chicago debuts we take for granted. Chrysler often chose its home turf to debut new cars, so the few times its unveilings happened elsewhere tend to stick in our minds. The first Challenger SRT-8 was kind of garbage, if we're being honest. I mean, who buys a race-bred, V8-powered muscle car without a limited-slip differential? But the SRT-8 formula evolved over time into something truly special, and what we saw in Chicago was essentially the early version of the Scat Pack, which was ultimately very successful for Dodge. And who would have thought we'd be here, 15 years later, still talking about that debut? And still loving these big Mopars, flaws and all. — Associate Editor Byron Hurd SHO time in Chicago IÂ’ll always have a certain fondness for the return of the Taurus SHO at the 2009 Chicago Auto Show. Chicago has always leaned truck and van heavy for press reveals, but every now and then, as this list illustrates, something spicy would appear. The return of the SHO as a high-powered successor to the original that ran from 1989-1999 gave enthusiasts hope for FordÂ’s performance business, especially for sedans. With a 3.5-liter EcoBoost V6 packing 365 hp, all-wheel drive and five-spoke wheels, the SHO was a nice upgrade from the lower-rung Taurus models. It was a bit more sedate than the original SHOÂ’s Yamaha-sourced V6 that teamed with a five-speed manual transmission, but still a worthy response to the Chrysler 300, Dodge Charger and later the Chevy SS. The SHO — Super High Output — begat things like the Fusion ST and gave Ford solid four-door performance for the rest of the decade.
