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 EV design is diverging in three directions

As the movie awards season kicks into high gear, Nissan design chief Shiro Nakamura appears to be implying that his company's electric-vehicle design prospects are about to go from Philomena into The Wolf of Wall Street territory. Nakamura, speaking with Motor Authority at the Detroit Auto Show last week, allowed that the design of the five-seat Nissan Leaf is fairly conservative and will remain so given that the model continues to be the most practically-minded EV from the company. In the near future, though, Nissan is planning to head in different directions. Specifically, an all-electric sports car and a two-seat commuter vehicle that could come with in-wheel electric motors that will allow the designs to get more radical. How radical? Well, we've heard Nissan may bring the BladeGlider concept (pictured) it unveiled at the Tokyo Motor Show late last year to production. It has a narrow front and wider rear and a 1+2 seating arrangement. Beyond that, Nissan has the two-seat Esflow concept vehicle it showed off in 2011 that could provide some hints, since it's expected that some of the design components from that car will be worked into the upcoming production models.

Nissan Sentra crash rating improves, now Top Safety Pick [w/video]

After a poor showing in the hands of the Insurance Institute of Highway Safety back in 2013, Nissan is back for another round of crash testing with its 2015 Sentra, and it's walking away with a Top Safety Pick. The compact sedan's small overlap front crash test rating improved from "poor" to "good", owing to internal improvements to the A-pillar, door sill and front structure, IIHS said in a statement. The dummy, in this most recent test, was at a low risk of injuries because of the structural changes. Take a look at video of the Sentra's small overlap crash test, available up top, and the official press release down below. 2015 Nissan Sentra earns TOP SAFETY PICK award ARLINGTON, Va. - The 2015 Nissan Sentra has improved from a poor to good rating in the Insurance Institute for Highway Safety's small overlap front crash test, qualifying for the TOP SAFETY PICK award. The small car's front structure, A-pillar and door sill were modified to reduce intrusion in small overlap crashes. In addition, the side curtain airbag was lengthened to protect the driver's head. In the latest test, the driver space was maintained well, with maximum intrusion of less than 5 inches at the lower door hinge pillar. The dummy's movement was well-controlled. The head hit the front airbag and stayed there until rebound, while the side curtain airbag had enough forward coverage to protect the head from contact with side structure and outside objects. Measures taken from the dummy indicate a low risk of injuries in a crash of this severity. In contrast, the 2013-14 Sentra didn't hold up as well in the test. Intrusion measured as much as 13 inches at the lower hinge pillar. The dummy's head slid off the left side of the frontal airbag, and the side curtain airbag didn't offer adequate coverage. Measures from the dummy indicated that injuries to the left leg would be possible in a crash of this severity. Introduced in 2012, the small overlap test replicates what happens when the front corner of a vehicle collides with another vehicle or an object such as a tree or a utility pole. The Sentra's good ratings in the moderate overlap front, side, roof strength and head restraint tests carry over to the 2015 model year. To qualify for the 2015 TOP SAFETY PICK award, a vehicle must have good ratings in those four tests and a good or acceptable rating in the small overlap test. Related Video:
