NHTSA may investigate new Toyota unintended acceleration case

After paying a $1.2-billion settlement to the US government last year, Toyota largely put the unintended acceleration recall behind it. Although, there were still some civil lawsuits to handle. A new case where the owner of a 2009 Lexus ES350 is petitioning the National Highway Traffic Safety Administration to open another analysis could draw the issue back to the forefront. Investigators are still deciding whether to research these claims further, though. According to this petition, the owner's wife was driving the ES350 in February 2015. While pulling into a parking space, the sedan allegedly surged forward, and there was a low-speed accident. The claim asserts there are at least two other similar cases in NHTSA's database: one in a 2009 Camry in 2009 and another in a 2010 Corolla in 2014. Specifically, this person wants an "investigation into low-speed surging in different models of Toyota automobiles in which the car starts accelerating and the engine RPM increases even when the accelerator pedal is not depressed," according to the agency. NHTSA will do further research into this person's claim and will decide whether to conduct a full investigation into the alleged issue. This won't be the first reappraisal of unintended acceleration in Toyotas by the agency in recent months, though. Between September 2014 and May 2015, NHTSA evaluated a similar petition with allegations covering 2006-2010 Corollas, and the government body decided to deny that one because the problem couldn't be replicated.

The petition was prompted by a February 2015 crash involving a model year (MY) 2009 Lexus ES350, which allegedly surged as the petitioner's wife was pulling into a parking spot.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.

Toyota World's Top-Selling Carmaker For Second Year

Toyota remained the top-selling automaker for a second year in a row, beating U.S. rival General Motors by some 270,000 vehicles in 2013, and set an ambitious target to sell more than 10 million vehicles this year. That would mark a milestone as no automaker has ever topped annual worldwide sales of 10 million. Toyota Motor Corp. said Thursday it sold a record 9.98 million vehicles worldwide last year, up 2 percent from the previous year. The Japanese automaker has made an impressive comeback from an earthquake and tsunami that devastated northeastern Japan in 2011, damaging auto suppliers and hobbling production. Toyota also outlined plans to sell 10.32 million vehicles and produce 10.43 million vehicles in 2014. General Motors Co. sold 9.71 million cars and trucks worldwide last year, outselling Volkswagen AG of Germany at 9.5 million. Toyota recaptured the global sales crown in 2012 from GM, which had been the top-selling carmaker for more than seven decades until being surpassed by Toyota in 2008. Toyota, which makes the Camry sedan, Prius hybrid and Lexus luxury models, had strong sales growth last year in overseas markets, although sales fell in long stagnant Japan. Toyota's U.S. sales totaled nearly 2.24 million vehicles, up 7 percent from the previous year. Its China sales were also strong, surging 9 percent to 917,000. Toyota remained optimistic about prospects this year for both regions, expecting sales to grow 3 percent in the U.S. to 2.3 million vehicles, while adding 20 percent in China sales to 1.1 million. The company was typically low-key about the bragging rights for being No. 1, reiterating its comments from previous years that it was merely making one car at a time to appeal to global consumers. GM has also expressed similar sentiments, but being the top seller is a key morale booster for the employees and related companies. The healthy results at the three rivals reflect the momentum of growth in the auto industry. Toyota has undergone tough times in recent years, such as a massive recall fiasco in the U.S. involving more than 14 million vehicles for sticky gas pedals, faulty floor mats, problematic brakes and many other defects, spanning several years from 2009.
