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:

2018 Mazda6 gets more power, efficiency to go with updated looks

The 2018 Mazda Mazda6 will debut at the L.A. Auto Show later this month, and the company released teaser images of the exterior and interior Wednesday – both of which tell us a lot about the new car. Mazda also said the sedan will have more efficient and more powerful engines. Starting with the visuals, the car doesn't look extraordinarily different from the current model, but there are notable changes. Up front, the Mazda6 now has a deeper-set grille with a 3D mesh instead of slats. The chrome strip that wraps around the lower part of the grille extends across the width of the headlights, too. Both of these cues are pulled from the Mazda CX-5. From what we can tell in the image, it looks like most of the sheetmetal along the sides and top are roughly the same as the current model. The interior also isn't a major departure from the current car, but the changes do make it cleaner and more elegant. All of the air vents sit along one slender plane that stretches across the interior. It leaves the top of the dash uncluttered and makes the vents look like a more integrated part of the design. Below the vent strip is another line of what appears to be vinyl or leather trim, and below that are the climate controls. The updated looks are accompanied by significant mechanical upgrades. While the current model offers just one engine, a naturally aspirated 2.5-liter four-cylinder, the new car will have two options. The first is again a naturally aspirated 2.5-liter engine, but it now has cylinder deactivation, allowing it to run on just two cylinders at times. For those who prefer power to efficiency, the Mazda6 will also be available with the turbocharged 2.5-liter four-cylinder from the CX-9 crossover. In that application, it makes 250 horsepower and 310 pound-feet of torque. The full reveal of the car happens on November 29 at the L.A. Auto Show. Be sure to check back then for more photos of and details about the car. Related Video: Image Credit: Mazda LA Auto Show Mazda Sedan

Mazda plans to launch an EV in 2020, plug-in hybrid by 2022

Thanks to an interview Automotive News Europe conducted with Mazda president and CEO Akira Marumoto, we have more insight on Mazda's plans to lower its vehicle emissions in Europe. This will undoubtedly bring changes to the U.S. lineup, too, but The Continent sees the first fruits in part because Mazda is well over the European Union's fleet CO2 emissions target for 2021 of 95 g/km. In response to how Mazda plans to achieve the necessary reduction, Marumoto said the carmaker will launch its first EV in 2020 and have a plug-in hybrid on the road in 2021 or 2022. First, some clarification on the emissions numbers and timeline. The 95g/km figure is based on the New European Driving Cycle (NEDC) emissions schedule being phased out next year; the AN piece cites JATO Dynamics findings that Mazda Europe's fleet CO2 average is 135.2 g/km. The new Worldwide Harmonised Light Vehicle Test Procedure (WLTP) schedule comes into full effect in 2020, the fleet CO2 target under that methodology translating to 114.9 g/km. The rules dictate that 90 percent of an automaker's range needs to meet the cap number by the end of 2020, the rest of the lineup must come into compliance by the end of 2021. Failure means enormous fines. Industry analyst IHS Markit estimates "average fines for those not complying could reach ˆ624 ($707) per vehicle at the end of 2020, with a further ˆ190 ($215) increase in 2021." The penalties quickly grow so large that Fiat will reportedly pay Tesla hundreds of millions of euros to pool their fleets and avoid an even larger bill. Mazda's most popular vehicle in Europe is the CX-5 with CO2 emissions ranging from 128 g/km to 150 g/km. On top of that, for a small automaker, the size of potential fines has material effect on the R&D budgets necessary to develop the technologies that will lower emissions, and whatever EV Mazda launches in 2020 needs to sway legions of customers into purchases to be of practical use. This will be challenging. A line in the IHS Markit summary about the industry in general states, "Once in 2021 and subject to full WLTP regulatory monitoring, only a seismic shift (over the baseline) in consumer demand for BEV ('Electric-Plug-In') and PHEV ('Hybrid-Full Plug-In) will result in the full mitigation of EU28 fleet level excess emissions premiums." Mazda hooked up with Toyota and Denso in 2017 on a joint venture called EV Common Architecture Spirit Co Ltd to develop EV technology.
