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.

North American production of foreign marques to jump in 2014

Wards Auto has released its North American Light Vehicle Production Forecast for 2014, and the report predicts foreign manufacturers will increase production on the continent some 3.9 percent by 2014. If accurate, that should see 123,000 additional cars, trucks and vans produced in North America, swelling the total number of units produced both by domestic and foreign manufacturers to 16.9 million light vehicles from a projected 15.6 million in 2013. Much of the increase can be attributed to the fact that Toyota intends to produce another car at its Blue Springs, MS plant as well as a new Lexus model at its Georgetown, KY facility in a year's time.
Likewise, Volkswagen intends to move production of a currently imported model to its plant in Puebla, Mexico. Daimler, Honda, Nissan and Mazda also plan to build additional models on North American soil for the first time. Around two-thirds of the new North American manufacturing will take place in Mexico, helping the country soak up a full 20 percent of the content's automotive production for the first time.

Toyota launches Pixis Space; first kei cars are Daihatsus in drag

Toyota has announced that it will unveil its first-ever kei car to be sold under its recently launched Pixis sub-brand. The vehicle, called the Pixis Space, will make its official debut in late September. Based on the Daihatsu Move Conte, the Pixis Space will be sold at Toyota dealerships through what the automakers calls "Pixis stations." Yes, seriously.
After Toyota's version of the Daihatsu Move Conte makes its debut, the Japanese automaker will launch a Pixis-badged Daihatsu Hijet truck and microvan in December. By the end of 2012, Toyota says it will launch a Pixis version of the upcoming Daihatsu e:S - a vehicle that returns 70.6 miles per gallon (U.S.) as measured under Japan's JC08 test cycle.
In case you weren't aware, Daihatsu - Japan's oldest manufacturer of automobiles - operates under the control of Toyota. In other words, these Pixis machines are simply badge engineering at the kei level.
