Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

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

Honda, Nissan, and Toyota expand Takata recall by millions worldwide

Honda, Nissan, and Toyota are expanding their global Takata airbag inflator recalls to cover millions of additional vehicles. Toyota alone is adding about 5 million vehicles to its campaign globally, and over 600,000 of those are in the US, according to Automotive News. Nissan's expansion includes an estimated 1.56 million cars worldwide, including about 326,000 in North America, but the exact models from the company are not yet known. According to Automotive News, Honda has also announced plans to increase the scope of its campaign but hasn't yet disclosed specific models, total numbers, or their location. Company spokesperson Chris Martin tells Autoblog that none of these vehicles are in the US, though. In the US, Toyota is replacing the driver's side front inflators on 160,000 examples of the 2004 and 2005 RAV4 nationwide. It's also swapping out the front passenger side parts for 177,000 units of the 2003 and 2004 Tundra (pictured above) and 2004 Sequoia. The automaker is also expanding its regional recalls in high-humidity areas to include the passenger-side inflators of 300,000 more vehicles. In total, the affected models are 2005-2007 model-year Corolla, Matrix, Sequoia, and Lexus SC; plus the 2005-2006 Tundra is included, as well. All of the states that are covered by this campaign are listed in Toyota's announcement, below. In a statement to Autoblog, Nissan said that it's currently working with the National Highway Traffic Safety Administration on this campaign. "We expect to have a more formal statement and additional information by Friday, May 15," the company said. TOYOTA EXPANDS TAKATA AIRBAG SAFETY RECALLS TORRANCE, Calif., May 12, 2015 – Toyota Motor Sales, U.S.A., Inc. today announced that it is expanding its recalls involving Takata air bag inflators. First, Toyota will conduct a recall to replace Takata-supplied driver front airbag inflators on approximately 160,000 model year 2004 and 2005 RAV4 sport utility vehicles. The inflators could potentially be susceptible to rupture when deployed in a crash, increasing the risk of injury to vehicle occupants. For similar reasons, Toyota will expand two existing recalls for Takata-supplied front passenger airbag inflators, namely: Toyota's nationwide recall launched in April 2013 will expand to include approximately an additional 177,000 model year 2003-2004 Tundra and model year 2004 Sequoia vehicles.
