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 TRD Pro Chase Trucks are ready to hit the desert at SEMA

Toyota marks the 35th anniversary of its Toyota Racing Development performance arm this year, and the division is celebrating at this year's SEMA Show with a quartet of tuned off-roaders based on on the 4Runner, Tacoma and Tundra that look more than ready to go just about anywhere.
All four of them will take part in this year's Baja 1000 race, but only the Tundra (far left in the above photo) is actually competing. The other three will be there to act as support vehicles.
Inspired by the production TRD Pro Series trucks, the 4Runner, Tacoma and Tundra are prepared by off-road fabricator N-Fab with a mix of TRD and the company's own parts to be able to take whatever the grueling, 1,000-mile can throw at them. The trio is fettled with extra communications equipment, GPS, additional lights and all sorts of body and suspension modifications to help them survive the ordeal.

Land Rover, Toyota big winners in ALG top resale value awards

"Residual value is important for automakers and consumers because it's a complete indicator of the vehicle's future value." - Larry Dominique
Toyota and Land Rover took home the top brand honors in ALG's 2015 Residual Value Awards, which will be presented this week at the Los Angeles Auto Show.
