Weekly Recap: GM plans massive new paint shop at Chevy Corvette factory

General Motors is laying out some serious green to maintain the Chevy Corvette's expansive color palette. The automaker is breaking ground on a new paint shop this summer that's part of a $439-million investment to upgrade the 34-year-old Bowling Green, KY, factory that builds the Stingray. The massive new structure will total 450,000 square feet, nearly half the size of the current 1-million square-foot facility. Construction is expected to take two years and won't impact Corvette production. The upgrades include new robots that save paint and create a better finish, longer, more efficient ovens to bake in the finish, and LED lighting. There's also a dry scrubbing booth technology with a limestone handling system that eliminates waste. GM has invested $135 million in the factory in last four years for the changeover to build the C7 and to relocate its Performance Build Center to Bowling Green. The improvements continue to modernize the Kentucky factory, which has become a tourist attraction in its own right, as more than 56,000 enthusiasts visited it last year. The upgrades are part of a $5.4-billion investment GM confirmed in April that will remake its US footprint in the next three years. The Bowling Green expansion underscores GM's continued commitment to the Corvette, which sold nearly 38,000 copies around the world last year, an eight-year high. "With this major technology investment, we can continue to exceed the expectations of sports car buyers for years to come," North American manufacturing manager Arvin Jones said in a statement. OTHER NEWS & NOTES Takata recall hits 34 million vehicles The National Highway Traffic Safety Administration expanded the Takata airbag recall to an almost unthinkable 34 million vehicles on Tuesday. The recall is part of an agreement reached by the two sides where Takata admitted some of its airbag inflators have a defect, and the deal compels the company to comply with all future regulatory actions and investigations. Takata's airbag inflators were produced with "a propellant that can degrade over time" and lead to ruptures, NHTSA said. Six deaths have been attributed to the flaw worldwide. Investigations conducted by Takata, automakers, and others have not determined the exact cause of the inflator problem, but NHTSA said moisture appears to alter the propellant's chemical structure. It then ignites too rapidly, creates too much pressure that ruptures the inflator, and blasts shards of metal at passengers.

Lexus, Mazda and Subaru top Consumer Reports Brand Report Cards

A revised methodology in devising its annual Car Brand Report Cards has seen Consumer Reports award Lexus its top overall ranking for 2013. For the first time ever, the institute broke out individual brands from their larger corporate umbrellas, meaning car makers like Lexus and Scion were judged independently from parent company Toyota. That strategy worked out well for Lexus, as the luxury brand earned a top report card score of 79 for the 2013 model year.
The institute has recommended every one of the Lexus models it has tested to date, and said that the company's products won out thanks to "a foundation of plush and very reliable vehicles."
Meanwhile, Mazda and Subaru tied for the second-highest scoring report cars, with scores of 76. Subaru earned praised for sporting models like the BRZ, which CR testers apparently had a lot of fun driving (naturally), while the Mazda products were lauded for their blend of practicality, sportiness and efficiency. Both of the Japanese brands offered good handling, fuel economy and versatility, said Consumer Reports.

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.
