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.

Jim Lentz exposes more details behind Toyota's move to Texas

Toyota's North American CEO Jim Lentz has already given us a rough idea of what prompted the company's surprise move to the Dallas suburb of Plano, TX from its longstanding headquarters in Torrance, CA. A new story from The Los Angeles Times, though, delivers even more detail from Lentz on the reasoning for the move, what other cities were considered and why the company's current host city wasn't even in the running.
Of course, one of the more popular reasons being bandied about includes the $40 million Texas was set to give the company for the move, as well as the state's generous tax rates. According to Lentz, though, the reason Toyota chose Plano over a group of finalists made up of Atlanta, Charlotte and Denver, was far simpler than that - it was about consolidating its marketing, sales, engineering and production teams in a region that's closer to the company's seat of manufacturing in the south.
"It doesn't make sense to have oversight of manufacturing 2,000 miles away from where the cars were made," Lentz told The Times. "Geography is the reason not to have our headquarters in California."

PickupTrucks.com's latest test results in a familiar winner [w/video]

PickupTrucks.com has gone and thrown the latest batch of half-ton pickups into a cage match to see who would come out on top. The site put the 2014 Chevrolet Silverado 1500, GMC Sierra 1500, 2013 Ford F-150, Ram 1500, Toyota Tundra and Nissan Titan through a battery of tests. Those included 0-60 miles per hour acceleration, 60-0 mph deceleration, fuel economy, a hill climb, and payload and towing. They even threw the rigs on an autocross course to evaluate overall handling. Each truck was given points based on how it scored in each evaluation.
Who came out on top? Somewhat surprisingly, the 2013 Ford F-150 walked away with the gold, though fewer than 50 points separated first and fourth place. Head over to PickupTrucks.com to read the full evaluation and the final results. You may be shocked to see exactly where some of the segment's newest additions placed. You can also watch a video on the test below.
