Toyota recalling 342k Tacomas due to faulty seatbelt pretensioners

Toyota is voluntarily recalling 342,000 Tacoma Access Cab pickups, produced between 2004 and 2011. The wide-ranging recall is due to faults in the screws that attach the belt pre-tensioner to the belt retractor. There are concerns that the screws can loosen themselves over time, especially if the access door is opened and closed with too much force. It's important to note that the recall only covers the driver and front passenger seat, and is limited to just the Access Cab trucks. Other body styles aren't affected.
If the screws come loose, the pre-tensioner and retractor spring could separate from the belt entirely, which would be bad news in a crash. There's no mention of injuries or accidents due to the faulty pre-tensioners. Owners affected by the recall will be notified soon, and asked to come in for recall service.

2014 Toyota Corolla shows just enough to keep us interested

To date, the best idea we have of what the 2014 Toyota Corolla will look like is the shape and styling of the Furia Concept from this year's Detroit Auto Show. Obviously the compact car will turn down the wick a fair bit from that orange machine, and now we have one more scintilla of an idea of what the final product will look like.
Published today on Toyota's official Facebook page, the image above clearly shows the rear quarter of the 2014 Corolla S. Though the low angle is pretty wonky, we can make out that the shape of the taillight cluster is very similar to that of the Furia, albeit without the same LED treatment, A hint of a trunk-lid spoiler is also in evidence, and also follows the Furia's lead.
Toyota points out that the new Corolla will be shown in earnest on June 6. Expect to see the full version of the car by that date at the latest - online leaks have a tendancy to speed these things up.

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.
