Mazda Skyactiv-D racer first diesel to run at Indy in 60 years

While it may not be touting the old "Win on Sunday, sell on Monday" axiom we all know and love, Mazda recognizes that racing can only improve its cars. And so it's no surprise that the Japanese automaker is testing and refining its Skyactiv-D diesel engine by sending it out on various race tracks around the country - notably being the first diesel ever to compete at Daytona and the first to notch a Grand Am win at Road Atlanta.
Next up? Indy. It has been over 60 years since a diesel-powered machine ran at the Indianapolis Motor Speedway, and the Cummins-powered racer that competed in the 1952 Indy 500 with a 6.6-liter inline-six-cylinder oil-burner was a fast and brutal machine that set a new lap record in qualifying leading up to the race. Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to accomplish once again.
Mazda says that the diesel engine in its race car is pretty darn close to stock - 51 percent stock by parts count, and 63 percent stock by weight - which means the way it performs in competition is at least a somewhat meaningful way to the stock engine's durability in the real world. Check out the image of the Mazda6 Skyactiv-D racer posing alongside the 1952 Cummins above (click to enlarge) and feel free to peruse the press release below for the rest of the details.

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.

2016 Mazda MX-5 Miata to make video-game debut next week in Forza Horizon 2 [w/video]

We've driven the all-new, fourth-generation Mazda MX5 Miata. Have you? Well, probably not. With the new roadster not set to hit dealerships until later this year (at the earliest), you might be stuck waiting a bit to climb behind the wheel of the highly regarded two-seater. Of course, if you happen to own Forza Horizon 2, your wait will be significantly shorter. And it'll be absolutely free to boot. The new convertible will make its video-game debut as part of a four-vehicle car pack for the open-world racing title. Downloads will start on March 17. Alongside the new MX-5, the Mazda car pack will also add representatives from each of the roadster's first three generations. Repping the NA will be the 1990 MX-5. The second-generation NB will be represented by the turbocharged 2005 Mazdaspeed MX-5, while the NC will arrive in the form of the Super 20 Concept, shown back at the 2010 SEMA Show. On top of the new vehicles, gamers will also have a chance to win a 2016 MX-5 as part of the new Mazda MX-5 Challenge. Running from March 17 to April 30, those interested in a free Mazda will need to lap its virtual counterpart around the Sisteron Perimeter Sprint Circuit, with the two fastest drivers slated to take part in a head-to-head race in June. The winner will walk away with their very own 2016 MX-5. Oh, and as a final juicy tidbit, the press release clearly states that the Miata weighs in at just 2,332 pounds – just a smidge more than the original NA. (That's with the manual transmission, of course – automatic cars are said to weigh 2,381 pounds.) You can get more specific details on the contest, as well as read more about the car pack, in the attached press release. Check out the release, as well as a preview vid of the MX-5 Car Pack.
