Why Mazda did so well and Volvo so poorly in Consumer Reports survey

The poor performances of Tesla and all three domestic automakers got the headlines in Consumer Reports magazine's latest reliability survey, but there were other results that caught our interest. Tiny Mazda notched the biggest gain among the 29 brands included in this year's list, leap-frogging nine spots to No. 3. Buick, which was in the top 10 last year, fell 11 spots to No. 19, the biggest decline of any brand. And then there's Volvo, a brand often vaunted for its quality and reliability, dropping six spots to dead last. What gives? For starters, all three brands benefited or suffered in large part due to their relatively small portfolio of vehicles. So when raves or complaints rolled in for even one particular model, as was often the case, it weighed heavily on the entire brand. That's especially true when it involves a relatively high-volume, hot-selling model such as the Buick Enclave (more on that in a moment). Mazda fared as well as it did despite the CX-3 losing Consumer Reports' influential "recommended" status due to problems with its climate system, including leaks from the condenser and refrigerant unit that triggered a service bulletin from the automaker in late 2016. Deputy auto editor Jon Linkov said that scratch didn't hurt the overall brand, since the CX-9 crossover and MX-5 Miata both jumped up to replace it on CR's list of newly recommended vehicles, thanks to several back fixes Mazda made to both models. For Buick, the redesigned Enclave SUV earned a "Much Worse Than Average" rating after owners reported problems with the new nine-speed automatic transmission it shares with the Chevrolet Traverse as well as some issues with the climate system. There were issues with rough shifting, plus complaints about the torque converter that necessitated fixes to the computer or outright replacement. "Again, similar stuff that we saw with the Traverse: both first-year vehicles, similar powertrains," LInkov said. He said all-new vehicles or redesigns typically fare poorly in CR's reliability survey due to issues that are hard to suss out before vehicles go into everyday use by consumers. The top-selling Encore and Envision fared well, Linkov said, but were outdone by the Enclave's problematic transmission components. The Enclave was Buick's second best-selling model through September at 35,227 units. Then there is Volvo, about which there is one word to sum up its woes: infotainment.

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 CEO closes door on talk of RX sports car revival

Some rumors in the auto industry simply refuse to die. Over the last decade, a few of the strongest have focused on Japan. A few years ago, we could have explained away the constant whispering over a new Toyota Supra, Acura NSX or Mazda RX-7 as nostalgia for Japan's golden era of performance. Today, though is different.
We already have the Nissan GT-R, and, thanks to the Toyota FT-1 Concept, a Supra successor finally appears to be on the way. Acura will someday, allegedly, deliver on its promise to put the NSX on sale. So where does that leave the third member of the Japanese performance trio mentioned above? Well, um, it still isn't happening.
"We don't have that kind of vehicle in our future product plan," Mazda CEO Masamichi Kogai told Automotive News when asked about a successor to the rotary-powered RX line. "If you increase the number of segments, then the resources we can allocate to each will decline and that will prevent us from developing truly good products."
