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

Electric Miata smokes Tesla Model S at the track

Yes, folks, you read that headline right. A souped up battery-electric version of a Mazda Miata took down a Tesla Model S on a quarter-mile drag strip. And it wasn't even close. Road Test TV was kind enough to post a video of a forest-green Miata (and its very stoked driver) doing a quarter-mile run in a rather brisk 9.27 seconds, beating the Model S sedan by a whopping 3.5 seconds in the process. And the Mazda crossed the finish line moving at 142 miles per hour, or 40 miles per hour faster than the Tesla was going when it finished the race. It's a good thing for the Tesla owner that they weren't racing for pink slips. Granted, the comparison is probably an unfair one because the Tesla was a stock, production vehicle (the P85 Performance model, but still), whereas who knows how the Miata was juiced up and how much cash it took to do the job. It's sort of like putting, say, an automotive writer against Usain Bolt because we ate the same breakfast and share 99 percent of our DNA. Still, the video does lend a certain credence to the idea that a battery-electric, super-light, rear-wheel-drive Miata would be a lot of fun, or at least a heck of lot more fun than any other Mazda out there. We're just sayin'. Check out the 100-second video below, and remember not to blink. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Mazda Hazumi Concept previews next Mazda2 in Geneva [w/videos]

The official photos of Mazda's Hazumi concept leaked out yesterday, but we have finally gotten to see it in real life at the Geneva Motor Show. Our view is that its Kodo lines looks as good on the diminutive car's sheet metal as they did in photos.
The Hazumi was designed to appear to be bursting with energy, and it seems to deliver. While Mazda refuses to actually say that this is the concept for the next Mazda2, it makes it clear that the little hatchback is "foreshadowing Mazda's next-generation subcompact car." We can all read between the lines.
Hazumi also introduces the new Skyactiv-D 1.5-liter diesel engine but details about it are scant at the moment. The specs for the engine are still unannounced, but the company promises that it is both very efficient and has lots of torque for its size. Mazda is also promising that its Mazda Connect infotainment system will be available in the car too. Scroll down for the brief press release a brace of videos that celebrate the tiny concept's arrival.
