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 teases a new compact SUV for Geneva

Mazda waited until the lights were out to tease the tidy rear end of a brand new crossover. The Japanese automaker didn't say much about the model that will debut at the Geneva Motor Show next month, only calling it "a brand-new addition to the Mazda lineup," and "the second model in new-generation lineup." We're going to put our chips down on this being the next CX-3 crossover, which has been predicted to arrive by 2020. If that's so, we can expect a larger model than the one currently on sale. The present, first-gen CX-3 rides on the Mazda2 platform. The coming CX-3 will use the Skyactiv Vehicle Architecture supporting the new Mazda3, growing out of the subcompact class into the compact segment. According to one report last year, the extra girth is a play for better sales in the U.S. market. In 2017, Mazda sold more CX-3s in Australia than in the U.S. The stronger, stiffer platform will introduce Mazda3's delights such as the human-centric interior ergonomics, and hopefully the same driving dynamics that we called "the life of the compact sedan party" in our Mazda3 First Drive. Yes, that's all but certain to mean a torsion beam rear suspension, which was said to have been done for NVH reasons after Mazda said it "got a lot of complaints from the media" over the multi-link rear. The engine lineup should mirror the Mazda3 in the U.S., being the naturally aspirated 2.5-liter four-cylinder at launch, followed by the Skyactiv-X. We can probably expect more teasers before Geneva press days kick off on March 5. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

Next Mazdaspeed3 could go naturally aspirated?

The new Mazda3 is a stunner, both aesthetically and from a driving perspective. As with all good things, though, there's always room for improvement. That's where the wizards from Mazdaspeed come in. Mazda's in-house tuner has been tweaking and turbocharging the five-door Mazda3 since 2007, with impressive results.
We've shown you renderings of what the third-generation Mazdaspeed3 could look like, and for the most part your response was quite positive. Now, AutoExpress has come out with details of just what might be under that long hood. According to our friends across the pond, the new Mazda3 MPS (that's what the Speed3 is called in Her Majesty's auto industry) will be arriving with a new, high-revving, naturally aspirated engine. Wait, what?
Yes, if the rumors are to be believed, the next Mazdaspeed3 will ditch its turbocharger. According to an anonymous engineer, the new MS3 will arrive in December (this is for the UK market, mind you) with a 200-horsepower, naturally aspirated engine. The 2.0-liter mill is based on the Skyactiv engine in the new 3, and should be capable of a sub-seven-second run to 62 miles per hour.
