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 retires robots in favor of humans to improve automaking process

Mitsuru Kawai is overseeing a return to the old ways at Toyota factories throughout Japan. Having spent 50 years at the Japanese automaker, Kawai remembers when manual skills were prized at the company and "experienced masters used to be called gods, and they could make anything." Company CEO Akio Toyoda personally chose Kawai to develop programs to teach workers metalcraft such as how to forge a crankshaft from scratch, and 100 workstations that formerly housed machines have been set aside for human training.
The idea is that when employees personally understand the fabrication of components, they will understand how to make better machines. Said Kawai, "To be the master of the machine, you have to have the knowledge and the skills to teach the machine." Lessons learned by the newly skilled workers have led to shorter production lines - in one case, 96percent shorter - improved parts production and less scrap.
Taking time to give workers the knowledge to solve problems instead of merely having them "feed parts into a machine and call somebody for help when it breaks down," Kawai's initiative is akin to that of Toyota's Operations Management Consulting Division, where new managers are given a length of time to finish a project but not given any help - they have to learn on their own. It's not a step back from Toyota's quest to build more than ten million cars a year; it's an effort to make sure that this time they don't sacrifice quality while making the effort. Said Kawai, "We need to become more solid and get back to basics."

2015 Toyota Sienna

It's hard to love a minivan, but it's very, very easy to use one. More than any other kind of vehicle - save a panel van, perhaps - the minivan is the most appliance-like of four-wheeled transportation devices. And most minivan buyers don't need to love their purchases; they just need to use them. So when it comes to a minivan's driving dynamics, who cares?
Well, we do. So we perked right up when Toyota talked about refinements it made to the 2015 Sienna, starting with some 142 added spot welds made to the body structure. Normally not stop-the-presses stuff, but Toyota says the added reinforcements prompted Sienna engineers to recalibrate the springs and shocks for improved handling, and our very limited wheel time along the (admittedly benign) roads on the Big Island of Hawaii revealed the 2015 Sienna SE model's handling to be tidier and more engaging than you'd expect for a porky, 4,560-pound, eight-passenger box on wheels.
