Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

Mazda's Tokyo concept foretells of rotary revival

Mazda has long been rumored to be planning a revival of its rotary-powered sports car. Some of those rumors may have come down to wishful thinking as much as concrete information. But now, on the eve of the Tokyo Motor Show, new details have come to light. The Japanese automaker is slated to unveil a two-door sports car concept, previewed in the teaser image above. Little in the way of firm information has been made available prior to the show car's debut, but sources are now citing senior company officials as confirming it has a rotary engine. "It is a two-door, two-seater, Mazda CEO Masamichi Kogai told Autocar. "It is a pure sports car design. We have MX-5 and another icon is a rotary sports car. We haven't talked about market reach but this would be in that segment." R&D chief Kiyoshi Fujiwara added: "People think rotary can not meet modern eco demands. The SkyActiv engineers worked on rotary and gave it cutting-edge tech. It is an essential part of our DNA and it [will] just be passed onto future engineers. It is synonymous with the brand. Some time in the future it will return and be called SkyActiv-R." The last time Mazda produced a rotary-powered model, of course, was with the RX-8, which ended production in 2012. That was preceded by three generations of RX-7, the first of which will be celebrating its 40th anniversary in 2018. If it manages to get the Wankel technology up to modern standards, that could provide just the right opportunity for Mazda to launch a new model. Reached for comment, Mazda spokesman Jacob Brown told Autoblog: "While we can confirm that Mazda continues to develop rotary engines, we cannot confirm production of a rotary at this point. Rotaries are one of the signature engineering technologies that define Mazda, and we will continue exploring them to see where they may fit for production applications." Related Video:

2019 Mazda MX-5 Miata Drivers' Notes Review | A little power goes to our heads

The Mazda MX-5 Miata is nearly 30 years old. The current car — dubbed the ND — is in its fourth iteration and packs a number of updates for 2019, most notably a bump of 26 horsepower and 3 pound-feet over the 2018 model. The car now makes 181 horsepower at 7,000 rpm while redline has been raised to 7,500. That might not sound like a lot, but when you're moving fewer than 2,400 pounds of steel, aluminum and plastic, it feels plenty strong. Our test car was a Soul Red roadster with a brown top, an odd but striking combination. A power-retractable top is available as the Miata RF. This top-tier Grand Touring trim comes with features like automatic climate control, heated seats and leather seats. It might not be the most practical or versatile car on the road, but it might just be the most fun for the money. Senior Editor, Green, John Beltz Snyder: I was excited when I woke up to the Miata covered in snow in my driveway. After all, this tester came equipped with Bridgestone Blizzak winter tires. By the time I could pry myself away from my work and take the car for a spin, though, the snow had mostly melted. I still had fun flinging this around on the cold, wet roads. The first thing I noticed was actually what I didn't notice ... I wasn't wishing for just a little more power, for once. Chalk it up to the conditions, or to the extra 26 horsepower Mazda added for 2019, but this felt appropriately potent. If anything, it's just enough to help get the rear end to wiggle a bit and the tires to more readily chirp in second gear. The Miata, fresh from the factory, has learned to do the cha-cha. Oddly enough, though, my wife, who has been salivating over this generation of MX-5 since the first time I brought one home, has cooled on it a little bit. We went out on a date night, and she was hyper aware of the noise and bumps, and I was, too, frankly. Something about bundling up under an icy soft top can kill the mood of this convertible. In the summer, the sound of the engine and telegraphic feel of the road beneath you blend with the warmth of the sun and the tug of the wind in automotive harmony. It's still fun to drive in the cold, but it doesn't quite turn on the charm like it normally does. Associate Editor Reese Counts: I've spent a lot of time behind the wheel of various NDs over the past few years. The weekend I got married, my wife and I drove a Soul Red roadster from Los Angeles to San Francisco for a brief honeymoon.
