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 tops Kelley Blue Book's Resale Value Awards

Kelley Blue Book announced its annual Best Resale Value Award winners, and we weren't too surprised to see the list dominated by Japanese automakers - mainly Toyota and Honda. KBB hands out the awards based on the projected residual value of mostly all 2013 model year vehicles, and Toyota skated home with a number of awards including 10 of the 22 overall categories and having five of its products in the top 10 for models with best resale value. KBB's Best Resale Value Awards were announced in the same week as the ALG Residual Value Awards, and there were many similarities between both lists, especially when it came to Toyota.
To come up with its winners, KBB measures depreciation over the first five years of ownership, and looks for the cars it expects to hold its value the best after this time; on average, the report says the 2013 model year vehicles will lose 61.8 percent of its value in five years. Of the 22 categories, 15 slots were filled by Toyota, Honda and Nissan products, while the Camaro and Porsche (Cayenne and Panamera) each took home a pair of awards. If Toyota has anything to be upset about in this list of cars, it's that categories for Hybrid/Alternative Energy Car and Electric Vehicle went to the Ford Fusion and Chevrolet Volt, respectively.
The overall top 10 models for the best resale value in 2013 are, in alphabetical order:

Toyota Pro/Celebrity race switching from Scion tC to FR-S [w/video]

Toyota has announced that the rear-wheel-drive Scion FR-S will replace the front-wheel-drive Scion tC as the racecar used by actors, singers and celebrities of all grades in its annual Toyota Pro/Celebrity Race. It's the first time a rear-drive vehicle has been used for the event in 27 years, with the tC having been in use since 2005, and the FWD Celica before that. This year's race takes place on April 20th amidst the festivities of the Toyota Grand Prix of Long Beach weekend.
The racing FR-S, which debuted today at the Chicago Auto Show, won't be left stock either, but rather outfitted with a range of official Toyota Racing Development parts and equipment, such as a stainless steel exhaust, new coil overs and springs, upgraded brakes, a bigger air intake and 18-inch wheels, not to mention all of the safety equipment required to keep the celebrities and pro drivers safe. The company says the performance mods have lifted horsepower to 210 from the standard car's 200. Check out the build process for the cars in the video below to see just how much work's been done.
The Toyota Pro/Celebrity race is also about more than just letting celebrities and pros do battle on a road course. The spectacle helps raise money for "Racing for Kids," a non-profit charity that supports children's hospitals in the US.
