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.

Mazda engineers urging execs for more RWD models

According to Edmunds, Mazda engineers are pressuring the company to create more rear-wheel-drive models, in an effort to better differentiate itself from its rivals. This push is reportedly coming from middle and senior engineers within the company, and these folks at Mazda believe this rear-drive strategy would allow the automaker to produce more distinctive, fun to drive cars. Mazda discontinued the rear-drive (and rotary-engined) RX-8 a few years ago, leaving the MX-5 Miata as the company's only RWD offering.
As enthusiasts, we're fully on board with Mazda offering more rear-drive cars, but unsurprisingly, the company's top management isn't exactly keen on the idea - and with good reason. First and foremost, the cost associated with redesigning fresh architecture for new models would be very high, and considering the fact that Mazda hasn't exactly been raking in the dough lately, an expensive new venture like this doesn't make a whole lot of sense. What's more, Mazda's latest front-drive models - the Mazda3, Mazda6 and CX-5 - have been very well-received, and are helping the company gain sales momentum.
But that doesn't mean there aren't other options. Edmunds reminds us that Mazda is already partnering with Alfa Romeo on the next-generation Miata, and if this collaboration is successful, perhaps the relationship could bear additional fruit. After all, Alfa Romeo is said to be working on returning to its rear-wheel-drive roots, so Mazda's engineers might be able to make a case for more RWD goodness after all.
