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 spiders return, 42k Mazda6 sedans recalled for webby fuel tanks

It seems that Yellow Sac spiders really, really love Mazda. Three years after Mazda recalled 52,000 Mazda6 sedans over spider webs obstructing the evaporative canister vent lines of 2009 and 2010 Mazda6 models, another recall has been issued for 42,000 more of the models built between 2010 and 2012 and equipped with the 2.5-liter four-cylinder engine.
According to the automaker, there have been nine confirmed sightings of spiders in vent lines since the original recall. It seems that covers were applied at the factory to keep the arachnids from entering, but it hasn't quite exterminated the problem. A reflash of the ECU is required that "[changes] the logic behind how the car purges the charcoal canister during normal operation," says Jeremy Barnes, Director, Public Relations & Brand Experience at Mazda North American Operations.
So far, Mazda has not recorded any fires, accidents or injuries due to this tangled mess of webs. Recall notices will be mailed out to owners later this month. Scroll down below for the statement from Mazda, along with the official recall notice from the National Highway Traffic Safety Administration.

Mazda6 diesel to race at Rolex 24, team and drivers announced

Mazda is getting serious about showing off the Skyactiv-D turbo-diesel four-cylinder engine in the Mazda6. The automaker has just announced it will campaign three diesel Mazda6 racers in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona in a quest to walk away with the company's 24th class win. Mazda partnered with SpeedSource to develop the race version of the new sedan, with Japanese and American engineers lending a helping hand where needed. Meanwhile, Freedom Autosport and Visit Florida Racing/SpeedSource/Yellow Dragon Racing will helm teams of their own.
Each car will make use of a five-driver team for the 24-hour race on January 26. In the interim, you can check out the full press release below for more information as well as the full driver roster. Mazda says we can expect to see the No. 70 SpeedSource car under the lights at the 2013 Detroit Auto Show later this month, as well.
