2014 Toyota Corolla gets marginal IIHS small overlap crash test score [w/video]

Toyota may have performed some major surgery on the 2014 Corolla, but that hasn't helped the Japanese automaker overcome tough new crash test procedures. The Corolla, Toyota's bread-and-butter compact sedan, managed only a Marginal score on the new small overlap crash test, which was just added last year.
Despite the low score, the Corolla performed well in the moderate overlap front, side, rollover and rear testing, which was enough to score it a 2013 Top Safety Pick. In testing in August, six of the Corolla's competitors earned the Top Safety Pick + award, for good or acceptable scores across the board.
According to the Insurance Institute for Highway Safety, the Corolla's "Marginal" score was down to an "intruding structure," that could cause injuries to the lower left leg. There was also concern that in a collision, the driver's head would move after hitting the air bag, and collide with the A-pillar or dash.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Toyota recalls 1.37 million more vehicles for Takata airbags

Toyota is expanding its passenger-side Takata airbag inflator recall campaign by an additional 1.37 million vehicles in the United States. The models covered under this broadened recall are the 2003-2007 Corolla, Matrix, and Lexus SC430; the 2005-2006 Tundra; and the 2005-2007 Sequoia. In total, Toyota says that this expansion brings the number of its vehicles covered under the Takata inflator recall in the US to 2.915 million. For these latest models, owners will be notified by mail soon. The move is similar to a recent decision by Honda to broaden its recall list. As with millions of other vehicles covered under these recalls, it's possible for exposure to moisture to cause the inflator to ignite too quickly in an airbag deployment. This can cause shrapnel to be sprayed at occupants. At least seven deaths have been potentially linked to these ruptures worldwide. TOYOTA EXPANDS TAKATA AIRBAG SAFETY RECALL TORRANCE, Calif., June 16, 2015 – Toyota Motor Sales, USA, Inc. today announced that it is expanding its recalls involving Takata front passenger airbag inflators. Based on recent information from Takata and the National Highway Traffic Safety Administration (NHTSA), Toyota will recall approximately 1,365,000 additional 2003-2007 Corolla and Corolla Matrix; 2005-2006 Tundra; 2005-2007 Sequoia; 2003-2007 Lexus SC430 vehicles. This brings the total number of Toyota and Lexus vehicles covered by Takata recalls in the U.S. to approximately 2,915,000. In the involved vehicles, the front passenger airbag inflators could potentially be susceptible to rupture when deployed and seriously injure vehicle occupants. "Toyota's focus remains on the safety and security of our customers, and we will continue to respond promptly to new developments so we can resolve issues for them as quickly, conveniently and safely as possible," said Dino Triantafyllos, chief quality officer, Toyota Motor North America. Multiple investigations into the root cause of the potential for inflator rupture are taking place, including by Orbital ATK, an independent engineering firm commissioned by an industry-wide joint testing initiative comprised of the ten automotive manufacturers conducting Takata-related recalls. All known owners of the affected Toyota / Lexus vehicles will be notified by first class mail to return their vehicles to a Toyota / Lexus dealer. The dealer will replace the airbag inflator with a newly manufactured one.
