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 Miata 25th anniversary display is roadster heaven on Earth

As part of the celebration of the 25th anniversary of the MX-5 Miata, Mazda has put together a rather large display at its New York Auto Show booth, showing off significant models from the diminutive roadsters history.
The display represents a healthy split of volume models, with cars 14, 15 and 17 sitting alongside cars 500,000 and 700,000. There are also more than a few concept cars in the offering, such as the Super20 Concept we drove a few years back, as well as older offerings, like the Club Racer concept from the 1989 Chicago Auto Show, the M-Speedster from the 1995 Chicago show and the M Coupe from the 1996 New York Auto Show.
We've put together a gallery of images of the historical Miata display, which you can view above. Take a look and then let us know which of Mazda's awesome roadsters is your favorite.

Mazda RX-Vision Concept revives the rotary

Mazda continues fighting to keep the rotary alive, and with the RX-Vision concept at the 2015 Tokyo Motor Show, the company unveils its dream for the engine's revival in a curvaceous sports coupe. Before any fans burst with excitement at the prospect, Mazda only "hopes" to have this gorgeous shape available in showrooms someday, for now. The RX-Vision starts with the classic elements of a front-engine, rear-wheel drive sports coupe by combining a long, low hood, short rear deck, and a passenger compartment way at the back. From there, Mazda's stylists add the swooping touches of the brand's Kodo design language. The result looks thoroughly modern and still subtly evokes generations of the RX-7 in the sculpted fenders and flowing roofline. Under that shapely hood hides Mazda's next-generation rotary, which the company has dubbed the Skyactiv-R. Unfortunately, details about it are quite scarce at the moment, including the displacement or even the number of rotors the engine uses. Still, Mazda is abundantly clear that development of the mill is very much moving forward. Mazda's designers opt for a retro flair inside with the deeply dished steering wheel and gauges in three pods. The rest is simple and elegant with a minimalist, metal gearshift rising from the center console and leather straps for door pulls. Finishing things off is a clean mix of red and black upholstery with a little carbon fiber for contrast. Expect live shots from Tokyo soon to show how the RX-Vision looks under the lights.

The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967.
