Mazda engineer wants new rotary to be turbocharged

Hope springs eternal for Mazda to revive the high-revving Wankel engine for a new sports car, and the company keeps feeding that thirst with hints that it could happen. To make the possibility even more tantalizing, Mazda drivetrain and powertrain assistant manager Tetsushi Marutani tells Motoring that he wants the updated mill to pack a turbocharger. "Personally, I think that a rotary with some turbo or compressor would be good," Marutani said to Motoring. "Because a rotary, in my opinion, they require more [torque at] low speed, low down torque. So if we have some small compressor or turbo it would help." Mazda hasn't sold a rotary-powered model since the RX-8 and hasn't had a turbocharged one since the third-generation RX-7. However, the recent RX-Vision concept (above) at least hinted at a possible Wankel revival, and Mazda officials confirmed that its engineers continued to develop the engine since the RX-8's demise. The RX-Vision used a next-gen rotary called the Skyactiv-R, but Mazda didn't officially confirm any details about it. Rumors suggested the engine had a two-rotor layout with a total displacement of 1.6 liters. A two-stage electric turbo and hybrid powertrain would allegedly boost the total output of around 450 horsepower. The electric assistance could also counter the Wankel's lack of torque at low revs and poor fuel economy. Those rumored specs sound fantastic, but we still take the rotary's return with a grain of salt. Mazda CEO Masamichi Kogai is adamant that it's not worth the company's limited resources to develop a niche sports coupe instead of better selling vehicles. Related Video:

Mazda recalls 1.37 million older vehicles for ignition switch short [UPDATE]

UPDATE: Mazda has confirmed to Autoblog that NHTSA's figures and list of effected models are accurate. Mazda is recalling 1,368,500 older vehicles in the US that date as far back as the late '80s because a potential short circuit in the ignition switch could cause a fire. According to the National Highway Traffic Safety Administration, the models include: 1990-1995 323 1993-1998 626 1993-1995 929 1989-1998 MPV 1993-1997 MX-6 1992-1993 MX-3 1990-1998 Protege Mazda reports that over time the grease around the switch's contact points can carbonize and become conductive, which can eventually lead to a short circuit. In some cases this results in smoke, but it could also lead to a fire. According to company spokesperson Tamara Mlynarczyk to Autoblog, there're no accidents, injuries, or fires in the US. Once the vehicle is running, the potential fault also doesn't affect drivability. Documents from NHTSA (as a PDF), indicate there was a fire in one of these vehicles in Japan in 2002 that could have been linked to this issue. The recall should begin in December. In its announcement of the issue below, Mazda reports 1.2 million vehicles affected and includes the 1990-1996 323/Protege. Autoblog has reached out to the company to understand the discrepancy.

In the affected vehicles, grease applied to the contact points inside the ignition switch may become conductive and overheat. CONSEQUENCE: If the ignition switch overheats there would be an increased risk of a fire. REMEDY: Mazda will notify owners, and dealers will replace the ignition switch, free of charge. The recall is expected to begin December 15, 2015. Owners may contact Mazda Customer Experience Center at 1-800-222-5500, option#6. Mazda's number for this recall is 8715J.

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.
