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:

R&T chases down a burglar in the million-mile Miata

Is the answer always Mazda Miata? We discussed this in passing on the Autoblog Podcast earlier this week, and most assuredly the answer is "no." For example, the little MX-5 would be a terrible people carrier, and it'd be useless off road. You can't really tow anything of substance with it, either. Still, if push came to shove, it's satisfying to know that the diminutive roadster could eke out a career as a chase vehicle for the police.
That fact was proven when Road & Track editor Chris Cantle did something that he himself recognizes as "stupid." Upon returning home, Cantle discovered a "twenty-something" actively burgling his home. The resulting story is easily one of the more entertaining episodes to come out of the 1990 MX-5's service to the team at R&T and, we're guessing, will be one of the highlights of the Million-Mile Miata challenge.
Be sure to head over to Road & Track for a full retelling of the chase from Cantle, as well as a follow-up on the saga.

MotorWeek checks out two sides of the '90s Japanese car scene

MotorWeek's Retro Reviews let you feel nostalgic about a huge range of classic cars, and the latest two releases offer a look at two very different sides of the Japanese car market in the 1990s. The video above shows off tuned examples of the Mazda RX-7 and Nissan 300ZX. Check out the clip below to remember the 1997 Honda CR-V, if you want to reminisce about something a little more utilitarian. The RX-7 and 300ZX were among the era's best Japanese sports cars, and these examples' suspension and engine overhauls gave them an extra boost. Peter Farrel Supercars tunes the Mazda, and the vibrant yellow paint and body kit make it look ready for an episode of Initial D. The updated powertrain stands up to the mean styling and gets the RX-7 to 60 miles per hour in 4.5 seconds. The Stillen 300ZX GTZ sports a giant wing, and new turbos take the output to 465 hp. It sprints to 60 in 4.9 seconds. The CR-V sits on the opposite end of the automotive spectrum as the tuned RX-7 and 300ZX, but it's even more important in a historical sense. The Honda (along with the Toyota RAV4 and others) was among the progenitors of today's mega-popular compact crossovers. These early examples set the foundation for offering buyers a utilitarian vehicle in a comfortable package with good fuel economy at an affordable price. The CR-V had some quirky charm, too, like the removable picnic table hidden in the cargo floor. This content is hosted by a third party. To view it, please update your privacy preferences.
