50 engineers kept the rotary alive at Mazda for 8 years

The Mazda RX-Vision concept is one of the standouts at this year's Tokyo Motor Show thanks to a drop-dead gorgeous design and a revival of the Wankel engine. The fact that the rotary is still in development at Mazda is thanks to a dedicated group of 50 engineers. According to Automotive News, their dream for the last eight years has been to bring this storied engine design back to the street. It won't be easy. Because of its design, the rotary suffers from poor fuel economy and high emissions. Making the challenge even harder, Mazda reportedly only gives them a small budget, but they continue to chip away at the problem. "These 50 engineers want to develop the rotary engine, therefore they joined Mazda," company research and development boss Kiyoshi Fujiwara told AN. "If I stop the rotary engine, probably they want to leave." For the Skyactiv-R under the RX-Vision's svelte hood, the team reportedly started from the 16X rotary project. Dating back to 2007, that 1.6-liter engine was supposed to improve torque and fuel economy thanks in part to direct injection. After additional development, insiders even suggested that the engineers might have finally solved the powerplant's issues. However, Mazda never put the mill into production, and the RX-8 remains the company's last Wankel-powered model to be offered in showrooms. "We have a dream that one day, this design with a rotary engine will achieve a level that customers will accept," CEO Masamichi Kogai said to AN. Mazda is quite clear that the RX-Vision might never go on sale without a suitable rotary. Although if it does see production, the coupe would likely use a stiffened version of the Miata's chassis, AN reports. Before anyone can place an order, these 50 determined engineers still have a lot of work ahead of them. Related Video:

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:

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.
