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.

180,000 new vehicles are sitting, derailed by lack of transport trains

If you're planning on buying a new car in the next month or so, you might want to pick from what's on the lot, because there could be a long wait for new vehicles from the factory. Locomotives continue to be in short supply in North America, and that's causing major delays for automakers trying to move assembled cars.
According to The Detroit News, there are about 180,000 new vehicles waiting to be transported by rail in North America at the moment. In a normal year, it would be about 69,000. The complications have been industry-wide. Toyota, General Motors, Honda and Ford all reported experiencing some delays, and Chrysler recently had hundreds of minivans sitting on the Detroit waterfront waiting to be shipped out.
The problem is twofold for automakers. First, the fracking boom in the Bakken oil field in the Plains and Canada is monopolizing many locomotives. Second, the long, harsh winter is still causing major delays in freight train travel. The bad weather forced trains to slow down and carry less weight, which caused a backup of goods to transport. The auto companies resorted to moving some vehicles by truck, which was a less efficient but necessary option.

Has the auto industry hit peak hybrid?

Hybrids are known for their great fuel economy and low emissions, but it looks like given current market conditions, only about three percent of new car consumers are willing to pay the premium for them. A new study from IHS/Polk finds that the hybrid market share among overall US auto sales are falling, despite more models with the technology on sale than ever before.
The study examined new car registrations in March from 2009 through 2014. In that time, the auto industry grew from 24 to 47 hybrid models available to consumers, but market share for the powertrain remained almost stagnant in that time. As of 2009, hybrids held 2.4 percent of the market; it fell slightly to 2.3 percent in 2010 and grew to 3.3 percent in 2013. However, 2014 showed a drop back to 3 percent. Overall hybrid sales have been growing since 2010, but they just aren't keeping up with the total auto market.
According to IHS/Polk, this isn't what you would expect to see. Usually, each new model in the market brings along with it a boost in sales. The growth in hybrid models 2009 to 2014 should have shown a larger increase in share for the segment.
