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 mulling Cummins diesel for Tundra?

When Bloomberg spoke to Toyota USA Sales CEO Kazua Ohara recently, we highlighted his comments on the possible return of the Toyota Supra. However, the interview started with Ohara discussing the Tundra, and how it would take time to pinpoint and hone the pickup truck's brand image in the minds of consumers. That effort could get a boost, with a report in Edmunds saying that Toyota is "evaluating" the addition of a Cummins turbodiesel to the Tundra's engine options.
The Cummins powerplant is one of two options for the moment, the other being a hybrid powertrain. If the oil-burner got the thumbs-up, Toyota would follow the recent example of Nissan, which announced it would put a Cummins turbodiesel into its 2015 Titan. While the two Japanese companies make a closer comparison since they're both talking about Cummins applications in light-duty trucks, if it happens, it could be seen as further diluting the once-exclusive tie-up that Ram trucks has had with Cummins even though Ram has used Cummins in its heavy-duty truck.
Toyota hasn't said when it will decide on which direction to take, but either will be a move for the better in the view of segment watchers; PickupTrucks.com said the first of its top-five fixes for the Tundra would be a better engine, perhaps a diesel-electric hybrid from Toyota's Hino unit. Cummins told Edmunds it can supply a second manufacturer with the 5.0-liter diesel that Nissan will be using, so we wouldn't be surprised to see it end up in a Toyota or somewhere else.

Toyota recalls 337,000 RAV4s and HS250h models for tie rod failure

UPDATE: The post has been updated with additional information from NHTSA. The Basics: Toyota is recalling 337,000 2006-2011 model year Toyota RAV4 crossovers built between October 31, 2005 and September 7, 2010 as well as 2010 model year Lexus HS250h cars built between July 6, 2009 and August 26, 2010. The Problem: When either an affected RAV4 or HS250h is given an alignment and the tie rod adjustment nut on the rear control arm isn't tightened properly, the threads on the tie rod can start to rust. If this happens, the nut may break off and throw off the alignment drastically and suddenly. This isn't a case of the car simply pulling to one side, either. This would seriously upset the balance of the car and could cause the driver to lose control and crash. This is also the third time these vehicles have been recalled for the same issue. Injuries/Deaths: It's unknown if this control arm issue has resulted in any injuries or deaths. Autoblog reached out to Toyota for more information, but a company representative told us that the company isn't able to discuss injuries or deaths caused by this issue (if any) at this time. Based on information from NHTSA documents, it does not appear that any crashes, injuries or deaths have been attributed to the defect addressed in the current recall. The Fix: The dealer will completely replace the rear suspension assemblies at no cost to the owner. The tie rods and nuts will also be coated in epoxy to prevent future rusting from occurring. According to Car and Driver, the previous recalls involved tightening nuts, coating decent tie rods in epoxy and completely replacing rusted ones. The car magazine reports that further complaints were filed and the company is now replacing all components regardless of condition. If you own one: Toyota will notify owners of affected cars by mail. Owners can also check whether their cars are affected by entering the VIN at safercar.gov/vin. Owners with questions can also reach Toyota customer service at 1-800-331-4331 or Lexus customer service at 1-800-255-3987.
