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 G-Vectoring Control makes driving better without you knowing

Mazda has just spent eight years developing a new technology that will make its new cars a lot more fun to drive, even if you have absolutely no idea that it's working. And subtlety's the point, Mazda engineers told us at a press event at Mazda Raceway Laguna Seca. In fact, the effects of what they've dubbed G-Vectoring Control are so fine that the marketing and PR teams are at a loss for how to do their jobs with it. "The engineers have done their work," said Mazda Director of Communications Jeremy Barnes, "But how do we get the message across?" The basic premise is this: G-Vectoring activates only when the car's on-board computer reads simultaneous steering and throttle input. The data — including throttle position, steering angle, and, crucially, how quickly you're adjusting the steering angle — are then funneled through an algorithm to reduce engine torque, which transfers vehicle weight, adding more grip to the wheels that need it. The system will appear first on 2017 Mazda6 sedans arriving in showrooms later this year, followed by the 2017 Mazda3. Actually, "subtle" does not even begin to describe the effect. G-Vectoring Control can detect as much as one tenth of one degree of steering angle, and changes the cornering forces only 0.1 to 0.5 g as a result. "That's less than the human body can feel," explained Vehicle Development Engineer Dave Coleman. In practice, G-Vectoring reduces the steering angle at turn-in, as well as the rate at which one turns the wheel. To demonstrate, Director of R&D Kelvin Hiraishi rode shotgun with us in a specially equipped Mazda6 that allowed him to turn G-Vectoring on or off at the push of a button (production cars will always have it on). Hiraishi had us drive a number of courses, including Mazda Raceway Laguna Seca itself, while an engineer measured our steering inputs with a laptop Matrix'd into the car's electronic brain. I drove the same course several times with the same car in the same conditions, with cruise control locked and the system turned on or off. Lo and behold, with G-Vectoring activated, the engineer's output graph showed that my steering inputs were indeed reduced ever so slightly. There were two times that G-Vectoring was markedly noticeable. The first on a turn with a minor banking toward the outside, and the second was during cornering over an artificially wet section of the course — in other words, when the car was at the limits of adhesion.

Mazda says 83 percent of new cars bear Skyactiv moniker

Mazda's US sales are down a little bit but the company's fuel economy is almost assuredly up. That's because its fuel-saving Skyactiv drivetrain technology is essentially taking over US vehicles sales. To the tune of about five out of every six vehicles sold, at least. While the Japanese automaker's US sales in February fell 2.4 percent from a year earlier, Skyactiv accounted for 83 percent of its sales last month. Most notably, Mazda6 sales jumped 46 percent from a year earlier, while Mazda CX-5 sales were up 72 percent. The company also celebrated the opening of its factory in Salamanca, Mexico, where it will make models such as the Mazda2 and Mazda3. The company is not resting on its fuel-economy laurels either, apparently. In January, it was reported the company is hard at work on its next-generation Skyactiv technology, which will boost fuel efficiency by as much as 30 percent by using diesel-like high compression. As it is, Mazda had the highest fleetwide fuel economy of any major automaker in the US for the 2013 model year with a 27.5 mile per gallon average, according to the Environmental Protection Agency (EPA). Honda came in second with 27 mpg. Check out Mazda's press release below. MAZDA SKYACTIV® TECHNOLOGY SETS RECORDS IN FEBRUARY - Mazda Celebrates Grand Opening of All-New Production Facility in Salamanca, Mexico - IRVINE, Calif., March 3, 2014 /PRNewswire/ -- Mazda North American Operations (MNAO) today reported February U.S. sales of 24,431 vehicles, representing a decrease of 2.4 percent versus last year. Year-to-date sales through February are down 6.7 percent versus last year, with 43,155 vehicles sold. Key February sales notes: Mazda's SKYACTIV® TECHNOLOGY accounted for 83.2 percent of all vehicle sales during the month of February. This is the largest percentage of Mazdas equipped with SKYACTIV TECHNOLOGY sold in one month, and second-best month of total volume ever with 20,245 vehicles sold. Mazda6 experienced its second-best February since 2008 with 3,945 vehicles sold, representing an increase of 46.0 percent, year-over-year (YOY). February 2014 was CX-5's best month ever with 9,353 vehicles sold, good for an increase of 71.6 percent, YOY. February was one of the most historic months for Mazda as it celebrated the grand opening of its all-new engine and vehicle assembly plant in Salamanca, Mexico.
