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

Nissan working on unspecified improvements to Carwings in Leaf EV

Fly a little higher, Carwings. Nissan has been using the communication system as a way for drivers of the battery-electric Leaf to do things like use a smartphone start the charging process remotely, check the charging status or find nearby charging stations. The service was one of the tools Nissan was offering to newbie drivers of the first US mass-produced electric vehicle to better familiarize themselves with ideas like recharging your car from miles away. Now, three-plus years into the model's lifetime, Nissan is looking to get more out of Carwings, Wards Auto says, citing Nissan North America executive Robyn Williams. Specifically, Nissan is hoping Carwings will eventually be able to communicate information about the battery's health, or lack thereof (i.e. degradation) to the driver. That issue was made clear a couple of years ago when Leaf drivers in hot-weather locales such as Arizona said their batteries were losing capacity at a faster rate than advertised. Nissan North America spokesman Brian Brockman, in an e-mail to AutoblogGreen, would only say that the automaker "is always working to determine ways to offer more value to customers via telematics systems like Carwings," but declined to be more specific about any particular technological advancements. Nissan debuted Carwings in late 2010, and, among other things, the concept was novel because it let Leaf drivers compare driving efficiency with other Leaf drivers (think of it as a real silent hypermiling contest). The feature had been used as a telecommunications system on a number of Nissan models in Japan for years before being introduced on the Leaf.

Nissan Bladeglider now on the backburner

There have been some big shakeups within Nissan's top executive ranks in the past 12 months, including Johan de Nyscchen leaving Infiniti to run Cadillac and Andy Palmer taking over Aston Martin. With them gone, the automaker's future product portfolio looks to be shifting as well. Among them, the chances are dwindling for the BladeGlider to actually arrive in dealers – already a rumored possibility. New Nissan planning boss Philippe Klein isn't nearly as hot on the idea of the BladeGlider as his predecessors. Where Palmer said last year the vehicle was in the brand's mid-term plan, Klein recently told Autocar that the model was "not among the immediate priorities." He didn't slam the door entirely on potential production, though. "It is still on the table, but at the end of the day it has to make sense to the company." Debuting at the 2013 Tokyo Motor Show, the BladeGlider translated the narrow-front, wide-rear wedge shape of the Deltawing and ZEOD RC racers to the street. In concept form, it used an electric drivetrain with hub-mounted motors, and the driver sat in the center with two passengers flanking them to the rear. According to Autocar, the project to develop a production version got at least as far as creating test cars from Ariel Atoms. The BladeGlider's renegade styling hasn't been the only thing holding it back from seeing the road, though. Panoz has a pending lawsuit against Nissan that claims the styling for the Nissan ZEOD RC and the BladeGlider infringe on the intellectual property for the Deltawing's design.
