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 i-ROAD leans its way into the city [w/video]

According to Toyota, the "i-ROAD takes the company closer to its goal of creating the ultimate range of eco cars." As you're surely aware, that range of eco cars includes the enormously successful Prius family, but this new machine is nothing like the hybrid hatchback. And it's not even a car - Toyota calls the i-ROAD a Personal Mobility Vehicle.
Toyota's i-ROAD Concept, which debuts at this week's Geneva Motor Show, is adorned with just three wheels, meaning it's just as much a motorcycle as it is a car, and the driver and passenger sit in tandem style instead of side-by-side. This arrangement allows for a very thin 850mm width, which is about the same as a large motorcycle. Because the cockpit is enclosed, the occupants don't need helmets, nor are they open to the elements outside.
Also like a traditional two-wheeler, the i-ROAD tilts through the turns and when driving on uneven surfaces. Toyota says its computer-controlled Active Lean technology automatically balances the vehicle with no input from the driver.

Toyota's new TNGA platform could boost Prius to 58 mpg

First, let's put the necessary context around the phrase, "Toyota New Global Architecture platform." The platform is important, but it is just one flowering bud sprouting from the real action, which is the production processes that will create it. It is crucial to understand that TNGA is fundamentally about a revolution in how Toyota designs and builds its cars - it even includes an overhaul of management and human resources - with one of the benefits being the new platform that the 2016 Prius will ride on. The Daily Kanban goes in depth about the changes, but integrated development for powertrain and platforms serves to reduces costs through more parts-sharing at the same time as it creates more cohesive platforms that are lighter, more compact, and have more efficient layouts. Regarding hybrids, Toyota says the new drive unit layout along with small components could raise hybrid efficiency "by more than 15 percent." That might enable the 2016 Prius to return 57.5-mpg combined - almost 59 in the city, 55 on the highway. Plus, the higher rigidity, lower center of gravity, and better suspension of the new platform will provide a better driving experience. All of these changes will be reflected in platforms for large and rear-wheel-drive vehicles, too. It is factory and build-process refinement that allows the development advances to be fully exploited. Toyota is making its lines more flexible, partly by having actual assembly lines that can easily be shortened, lengthened, or trucked somewhere else, and partly by introducing machines that can build parts for many different vehicles on the same line as needed, without using molds. The flexibility extends to capital investment, too, with much less money needed in order to switch to a new product build. Toyota says it is doing this to "improve core vehicle performance and product appeal," the overhaul making it simpler to produce new designs and features. Factory workers benefit from the flexibility as well; being able to build more types of cars means they aren't hamstrung by the sales fortunes of a small number of models.
