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.

2014 Toyota Highlander recalled over seatbelt anchors

Toyota has announced a small recall of its redesigned, 2014 Highlander over issues with one of its seat belts. The affected vehicles, which were built from November 20, 2013 to January 18, 2014, could have a seatbelt assembly in the middle seat of the third row that wasn't properly secured to a floor anchorage at the factory.
In total, 7,067 of the new Highlanders are included in the recall, which was discovered not after a crash, but during a post-build inspection at the factory. It's unclear if there have been any injuries as a result of the faulty seat belts.
Toyota is set to inform owners of the affected vehicles as well as dealers with the recalled Highlander models in their inventory. Naturally, repairs will be performed free of charge. For the full bulletin form the National Highway Traffic Safety Administration, scroll down.

First live photos and impressions of Toyota's 2014 Corolla

After releasing official pictures and a press release about an hour earlier, Toyota chose an aircraft hanger at the Santa Monica airport as the venue for the global introduction of its highly anticipated 2014 Corolla. Following an extended aerial acrobat show, which included performers running along the walls, swimmers romping in a massive overhead clear plastic pool and angry dancers destroying their cardboard stage in a glittery fit... the all-new C-segment star of the show was lowered on cables from the ceiling. (After the strobe lights and pounding sound that preceded it, the final vehicle reveal was almost anticlimactic.)
Face-to-face with the eleventh-generation sedan, we liked what we saw. Compared to last year's Corolla, the new model appears smaller in person - yet that is mostly an optical illusion. By the tape, it is four inches longer and slightly wider than its predecessor, but a bit shorter. The wheelbase has been stretched nearly four inches, yet the front and rear overhangs only give or take about an inch in the conversion. With the exception of the enormous wheel/fender gap (the new Corolla seems to ride too high), its overall proportions are very pleasing.
The fresh styling is modern and stylish, with sculpted lines that add character to a formerly bland sedan
