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

Toyota GT86 convertible could debut in March

The dates are lining up, now we wait to see how the badges align. Just before the Toyota GT 86/Scion FR-S/Subaru BRZ line-up was introduced at the Tokyo Motor Show last year, there was a report that Subaru was considering a convertible while Toyota wouldn't even comment on it. That got swapped around when earlier this year the chief engineer on Toyota's side said a convertible was coming, and then a Scion FR-S droptop was confirmed for early 2014.
Autocar now reports that the Toyota GT 86 convertible will make its first appearance at the 2013 Geneva Motor Show in March. In a car whose specs like weight, packaging, horsepower and center of gravity were all tightly controlled to get the most from the least, the changes necessitated by chopping the roof could make this a very different car. It's said to employ a fabric roof to keep a "small" weight gain check, and the suspension will be softened to work more harmoniously with the decreased body stiffness. And somewhere in all that the back seat and trunk space will need to take a hit.
In other news, Autocar says the hi-po GT 86 with some kind of capacitor system instead of batteries is being worked on for 2015.
