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.

Next-generation Toyota 86 and Subaru BRZ confirmed

Toyota and Subaru jointly announced today that they would be continuing and expanding their alliance. Toyota will be taking a larger stake in Subaru, bringing the total to 20%, and Subaru will respond in kind by buying shares equal to the value of those purchased by Toyota. In terms of product, the two companies will reportedly swap knowledge in the development of all-wheel-drive systems, battery-electric powertrains and connected/autonomous driving technologies. Oh, and there will be a next-generation Toyota 86 and Subaru BRZ. Despite less-than-stellar sales, the two companies confirmed that the rear-wheel-drive Toyabaru twins will be returning for a sequel. No details about them were provided, but a second-generation has widely been speculated and reported, with Australia's Motor quoting Supra chief engineer Tatsuya Tada confirming as such. "We have a new 86 team," he told Motor. "We have to make a new 86 that surpasses the Supra ... that is what the customer expects." Beyond that, there is rampant speculation of where the rear-drive platform will originate (a derivative of Toyota's TNGA platform, something boosted from Mazda, aliens), as well as what might find its way under the hood (virtually anything would be better than what's there now). A Japanese publication even suggested it might even be previewed next month at the Tokyo Motor Show.  In any event, expect the next-generation Subaru BRZ and Toyota 86 to be a continuous source of interest for the next few years.  Subaru Toyota Coupe Future Vehicles Performance

Toyota raises Japanese base wages for first time since 2008

Toyota is on track for record profits, and in return, its Japanese workers are receiving their first increase in base wages since 2008, plus higher pay based on seniority and a larger bonus for 2014. The Japanese automaker predicts the average laborer will net a 2.9 percent income gain.
The average Toyota employee will earn 2,700 yen ($26.28) more each month, a 0.8 percent increase from last year. Workers will also receive about 7,300 yen ($71.09) more monthly based on seniority and promotions. Finally, the company's union pushed through a median bonus of 2.44 million yen ($23,768) for 2014, the highest in 6 years.
The pay boost comes as Toyota forecasts a record 1.9-trillion yen ($18.5 billion) profit for the fiscal year ending on March 31, according to Bloomberg. It has been helped by the Japanese government's efforts to weaken the yen on international markets and expand inflation. Prime Minister Shinzo Abe has been asking businesses to increase compensation to end years of deflation and offset upcoming higher sales taxes. Honda and Nissan have also raised their wages there in recent months.
