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 16X rotary engine two years away, will arrive in all-new model

We last reported on Mazda's next-generation rotary engine project in June of 2012 when the automaker built its last Renesis-powered RX-8, but rumors of this new engine's development had been around way before that final car left the production line in Japan, last year.
We now have enthusiastic confirmation that this next-gen rotary engine is really and truly going forward. It is still referred to as 16X and has several priorities. First is to lower fuel consumption compared to the RX-8's engine, while still making gains in terms of performance. The second is to reduce the burning of oil that was happening at the highest revs. And the third and final priority, and perhaps most key for enthusiasts, is to give the powertrain a big torque upgrade.
What we were told by a Mazda USA insider (while we are all here together at the festivities in Monterey) is that the first application of the new 16X engine will be happening in two years' time in an as yet undisclosed new model. Oh, the mind races to our eternal Mazda wish list...

2017 Mazda Model Year Preview and Updates

Driving Matters, Mazda's marketing pitch, certainly resonates with enthusiasts, although may not be relevant with the increasing number of drivers engaged in texting while steering. Regardless of that disconnect, for drivers Mazda brings to market the long-awaited Miata coupe in Retractable Fastback (RF) form, pictured above. And for those wanting/needing a new crossover, Mazda redesigns its well-received CX-5. MAZDA3: Mazda's compact sedan and hatch receive a revised front end and tweaked rear. Inside, an upgraded interior with more storage space, improved sound proofing and materials round out the enhancements. On the road, all trim levels receive Mazda's G-Vectoring Control for enhanced handling and stability. MAZDA6: G-Vectoring Control is standard across all trims. Inside, improved sound insulation, new tech (including traffic sign recognition), and available Nappa leather takes an already upscale environment a few steps further into near-luxury. MAZDA MX-5 MIATA: The RF (Retractable Fastback) is the biggest news, as it serves as the answer to the long-awaited Miata coupe. Club models receive Blind Spot Monitoring and Cross-Traffic Alert – presumably helpful when the top is up. And the RF Launch Edition (1,000 examples) delivers a Nappa leather interior and hand-painted black top. The package is further embellished by Mazda's choice of Machine Gray metallic exterior color. MAZDA CX-3: Mazda's subcompact crossover receives minor updates. The Touring trim gets 18-inch alloy wheels, while the upmarket Grand Touring's available i-ACTIVSENSE is reduced in price. MAZDA CX-5: Mazda's compact crossover is all-new and on Mazda showrooms this spring as a 2017 model. Of particular interest to diesel fans is the introduction later in the year of Mazda's SKYACTIV-D 2.2 clean diesel, which arrives just in time for your Volkswagen buyback. MAZDA CX-9: Mazda's largest crossover is unchanged for 2017.
