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.

Mazda Furai concept designer talks about his car's passing

Last week, there was mourning at the Autoblog offices as word trickled in that the Mazda Furai concept - one of the coolest, best-looking showcars to grace an auto show stage since the wild and crazy 1960s -had been killed. It was killed on the track with the folks from Top Gear in attendance. We're sure the gods of driving would have wanted it to die on a circuit, but that doesn't make its fiery passing any easier to deal with.
The Furai is the rare concept car that had a lasting appeal with enthusiasts, partly because it was a real, functioning racecar, complete with a wacky three-rotor Wankel engine and cutting-edge Nagare design. Now that it's gone, though, Road & Track's Mallory McMorrow, who was an intern at Mazda Design when the Furai was being styled in 2007, has published an interview with one of the men who penned the Mazda showcar's striking exterior, Carlos Salaff. It's a great piece on the emotional connection between a designer and his creation, and one you should take the time to read. Click on over to R&T for the full story.

Mazda engineers say current Skyactiv-X might not suit U.S. market

We've been watching Mazda roll out the 2.0-liter four-cylinder Skyactiv-X engine in Japan and Europe, waiting our turn. When European authorities released fuel economy information for the high-tech motor last June, we wrote, "Mazda has yet to make an official decision on timing for the U.S market's launch of the engine." Automotive News spoke to Mazda engineers in charge of the powertrain, and based on the answers AN got, the question might not be when we get the Skyactiv-X, but if. Seems that the automaker now isn't certain whether the cost/benefit analysis for the U.S. market favors the engine, and there's concern the 2.0-liter might not be powerful enough for us with its current output of 178 horsepower and 186 pound-feet of torque. At the moment, our Mazda3 is served only with a 2.5-liter Skyactiv-G engine producing 186 hp and 186 lb-ft., not too far ahead of the Skyactiv-X. The Skyactiv-X would return better fuel economy, but requires a noteworthy price premium over the Skyactiv-G. The Truth About Cars says the Skyactiv-X has become the top-seller in the Japanese-market Mazda3, even though it costs 27% more than the base, 2.0-liter Skyactiv-G for a 9% improvement in fuel economy. Mazda's not sure U.S. customers would care much for that kind of math. Engineer Yoshiaki Yamane told AN, "Maybe U.S. customers require more power, because fuel economy is not the top requirement." There isn't much Mazda can do about the tech-heavy engine's cost, since pricey equipment like the high-pressure fuel injection and combustion systems, supercharger, three-way catalyst, and 24-volt mild-hybrid system provide the mileage gains that are the engine's reason for being. Instead, engineers are researching the system's effects with larger displacements. If it works as desired, a larger and more powerful Skyactiv-X could come to the U.S. on the large-vehicle architecture Mazda's developing for new sedans to arrive in a couple of years. That's the hope, at least. Remember, Mazda's Skyactiv-D was meant to go into the 2014 Mazda6, but didn't because Mazda said it needed more time to find "the right balance between fuel economy and Mazda-appropriate driving performance." After five years of "Soon," the engine showed up on the 2019 CX-5 that starts at $42,045. Based on that template, it could be awhile before we know how the U.S.-market Skyactiv-X story ends.
