Did Mazda designer Derek Jenkins leave to head up a 'Stealth Project?'

Not long after Derek Jenkins officially gave the 2016 MX-5 Miata to the buying world, he's left the Mazda building. Jalopnik reported that the head of design for Mazda North America changed the current job description on his LinkedIn profile to "Stealth Project." Mazda backed up the discovery with this reply to Jalop's inquiry: Derek left Mazda last Friday. He left on great terms in order to work on a new endeavor. We wish him the best of luck. He will be missed, but we are sure that he will do great things in the next chapter of his career. That "last Friday" would be July 17. Emphasizing the "stealth" bit in his new position, as far as we can tell, Jenkins still hasn't publicly answered any question about what he's doing. Every automaker has secrets, but traditional automakers usually make a hubbub about hiring big-name designers, especially one with Jenkins' resume. For his new employer to go all Ghost Recon with all information, well that's the kind of mystery this summer needs. The obvious culprit would be a certain fruit-named company in a certain Cupertino, CA office park. If that ends up being the case, Jenkins would be the second chief designer at Mazda NA to go electric: he replaced Franz von Holzhausen in the position after von Holzhausen went to Tesla. Various other Apple Project Titan hires have made the news, though. For all we know, Jenkins' project might not be automotive. So let's just go ahead and cue the speculation. We're looking forward to whatever he's got coming, and to whoever gets nominated to keep the full head of Zoom-Zoom going at Mazda NA.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

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.
