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:

Junkyard Gem: 1988 Mazda 323 GTX

Back in early 2007, when the late Davey G. Johnson got me my first job writing for an automotive publication (well, unless you count writing for the Year One catalogs back in the mid-1990s) and I took on this goofy pen name for real, I didn't quite grasp that any readers might be interested in the stuff I saw during my frequent junkyard trips. So, when I took my crappy Nikon Coolpix 2500 to the now-defunct Pick Your Part in Hayward, California, and saw a super-rare Mazda 323 GTX among all the Tercels and Rabbits in the IMPORTS section, I just took a few shots of this interesting car for my own enjoyment. These days, I'll take more than 100 photographs of a junkyard car of such great historical significance, editing them down to the best couple of dozen, but in March of 2007 I got just three of the 323 GTX. Robert Capa had his Magnificent Eleven at D-Day, and I've got the Magnificent Three of the GTX. Here they are. Any Mazda 323 of the immediate post-GLC era is a real junkyard rarity today, but Mazda sold very few of the all-wheel-drive, turbocharged homologation-special 323s over here during the 1988 and 1989 model years. A mere 1,243 of these cars made it to North American streets. Back in 2007, they weren't worth much (in fact, they still aren't incredibly valuable, if we go by Bring a Trailer real-world sale prices), and so this one showed up in El Pulpo's yard. These cars wouldn't be considered particularly fast by 21st-century standards, now that we've had decades of street-legal Mitsubishi Lancer Evos and Subaru WRXs flinging snow and mud around, and they tended to grind their powertrain components into a costly oil-and-metal-shaving slurry. But they were maniacally cool in the late 1980s, and that's enough. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

2016 Mazda MX-5 Miata First Drive [w/video]

Hypothetically speaking, if you blindfolded me, put me in the car pictured above, and told me to hit the road, it would have taken me maybe two minutes to figure out that I was driving the 2016 Mazda MX-5 Miata. There are just certain facets about Miata driving that have been baked into every generation of Mazda's roadster, and it makes for a symbiotic relationship between car and driver that's truly unique. Sure, I could rattle off a list of cars that come close to offering the same sort of experience, but they just can't quite capture the same intrinsic Miata magic. Mazda knows its Miata is an incredibly special machine. Listening to the company's engineers and designers talk about the development of this fourth-generation ND model is fascinating. The attention to detail is astonishing, and every single person involved in the Miata program knows that the most important goal is to keep this car as true to its predecessors' ethos as possible. It cannot just be a great convertible, or even a great Mazda – it has to be a great MX-5 Miata. But the company did not just want to improve upon the third-generation NC Miata, which has been around since 2006. They wanted to tie the ND Miata's roots back to the original NA from 1989. Back in '89, the Miata was a less-powerful, 1.6-liter model with 115 horsepower and 100 pound-feet of torque. Mazda's team said they are proud of every version of the MX-5, but it's this specific, first-generation model that the company calls the "most right" – the most true to the idea of what a Miata ought to be. So that's why, before being allowed to attack the winding roads of the Spanish countryside in the 2016 MX-5, Mazda wanted me to spend some time with a cherry example of the original NA Miata: a Mariner Blue darling that, even with some 239,000 kilometers on its clock, still felt absolutely impeccable from behind the wheel. Light, responsive, and perfectly balanced, it was the original embodiment of the harmony between driver and car that Mazda wanted in every Miata. Mazda executives said they felt the first Miata was also the right size. So they chopped off three inches on the ND compared with the NC, and put it on a wheelbase that's been reduced by six-tenths of an inch. In fact, these dimensions mean the new Miata is more than two inches shorter in length than the original, and only two-tenths of an inch taller. In this day and age of ever-expanding waistlines and footprints, it's a remarkable achievement.
