Mazda6 GX Grand-Am racer goes where no diesel sedan has gone before

There has never been a four-door diesel sedan in the Grand-Am series, until now: The blunt, bewinged grille of the Mazda6 GX has blown right through that wall. It's said that racing improves the breed, but usually the breed has gone on sale when the racing begins. One of the unusual aspects of the Mazda6 GX, on the other hand, is that while the diesel won't go on sale to the public until later this year, it will already have tasted racing blood by the end of the day. That kind of reversal is more likely found with super coupes like the Lexus LFA and Honda NSX.
Mazda has taken class wins at Daytona's 24-hour race a whopping 23 times since 1975, most recently in 2010 with the RX-8 in the GT class. This year the Hiroshima company decided to show off its SkyActiv technology, then turned things up to eleven by opting for its SkyActiv-D instead of the more conventional SkyActiv-G gas engine to run in the new GX class. It will be joined by competitors like the Lotus Evora and Porsche Cayman in the class, nevertheless, at 2.4 liters, it's the smallest engine on the grid.
Time has not been a friend, either - Mazda said that the first five SkyActiv-D engines off the production line went to Speed Source in Coral Springs, Florida, the company that preps Mazda's race vehicles. Still, race driver Jonathan Baumarito on the #70 car said that although the engine's been on the dyno since February of last year, it's only been in the car for about a month and there have been only a couple of test days.

Fiat version of Mazda MX-5 Miata to be called 124 Spider

Fiat has a definite use for its recent US trademark on the 124 Spider name, and it's something that should make many performance fans quite happy. FCA CEO Sergio Marchionne confirmed to Auto Express that the Italian brand's future roadster would bear the classic name. Auto Express reportedly asked Marchionne directly about the convertible at the 2015 Geneva Motor Show. The CEO said: "Do we want to do it now?" After another executive verified the name, Marchionne responded: "There you go – a world class premiere right in this room!" Autoblog reached out to Fiat Brand communications boss in the US Ariel Gavilan for more information, and he verified the story. Gavilan said that brand head Olivier Francois confirmed the 124 Spider name to international media during a briefing in Geneva. FCA isn't going quite so far as officially confirming that the 124 Spider shares a platform with the latest Mazda MX-5 Miata, but that's almost a certainty. The two automakers jointly developed the chassis, and the original plan was for it to underpin an Alfa Romeo. However, Marchionne didn't want an Alfa assembled outside of Italy. Fiat even hinted at this possible change as far back as the corporation's five-year plan last summer. Insiders tell Auto Express that the 124 Spider reportedly carries retro-inspired style, and hopefully, that means the roadster evokes the look of the original 124 Sport Spider (pictured above) by Pininfarina. Fiat allegedly is also aiming for a weight less than 2,205 pounds, and the engine range is likely comprised of versions of the brand's 1.4-liter turbo. The mill already pumps out 160 horsepower and 183 pound-feet of torque in the Fiat 500 Abarth in the US. According to Auto Express, Fiat and Mazda have an agreement to launch the Miata in 2015 and the 124 Spider in 2016. A hotter Abarth version could come along eventually, too. Related Video:

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.
