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:

Tow truck driver hilariously bad at righting a flipped Mazda

Can rolling your car get any worse? The correct answer is yes, as this poor soul found out when he rolled his Mazda3 onto its side. Calling a tow truck might be a logical, post-rollover move, but in this case, it kind of made the situation worse.
We don't want to give away just what happened, so you'll need to scroll down and watch the video. A fair warning, though, it does contain a moment of colorful language towards the end, so watching it at work, with the volume up, might not be wise. Have a look below for the full video.

This California rally is vintage Japanese car heaven

What's so good about the future? This is what I was thinking when some folks at Mazda invited me and a handful of other journalists to join them on the second-annual Touge California. It's a rally for classic Japanese cars that covers a huge chunk of Southern California's twistier roads, where fans get to test their beloved machines. Oh, and it attracts swarms of admirers with cameras. "It is not a race. It is a vintage touring rally," said Ben Hsu, editor in chief of Japanese Nostalgic Car, and one of the coordinators of the event. "In Japan, touge most definitely refers to racing, whether timed, in touge battles, or drifting antics. Touge California was created to give drivers of Japanese classics a taste, as close as possible, of the types of roads their cars were forged on." Touge California was created to give drivers of Japanese classics a taste, as close as possible, of the types of roads their cars were forged on. We started the day on a mundane stop-and-go freeway drive from Mazda's Irvine headquarters to Escondido, me riding shotgun with my journalist co-driver in a 2016 Miata. But Mazda also brought along three heritage products on this trip – a 1985 RX-7 GSL-SE, a 1978 GLC three-door hatchback, and a 1975 REPU (rotary engined pickup) – serving as reminders of the company's history in the U.S. The group of Mazdas was joined in Escondido by many more Mazdas. And Toyotas, Hondas, Datsuns – so many 240Zs – and the odd Subaru and Mitsubishi. In total, 28 cars were at the start line. "We doubled the field this year, and made the route longer – 200 versus 120 miles," Hsu said. "We separated the cars into two run groups based on speed and a mix of makes and models." I spent the first part of the rally in the Mazda pickup to get a taste of rotary power. It was my first experience behind the wheel of a Wankel-powered vehicle, my first time driving a small Japanese truck from the '70s, and my God that thing has a lot of power. I had a few scares when I had to stand on the brakes, and I found the shift throw's immense length disconcerting – it felt like third gear engaged somewhere in front of the dashboard, with fourth somewhere in the bed. The truck was a great introduction to the rotary, however, and to '70s Japanese cars. Especially in Southern California, old Japanese cars aren't as novel to casual observers as they might be in other parts of the country.
