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.

Judge halts Toyota unintended acceleration cases, triggers time for settlement negotiations

So far, the lawsuits brought forth against Toyota for unintended acceleration have gone both ways: the automaker was found not at fault in a 2009 California crash and liable for a 2007 crash in Oklahoma. Both cases involved a Camry and resulted in fatalities. With a big chunk of these UA cases (around 200) set to his the docket of US District Judge James V. Selna in Santa Ana, California, Bloomberg is reporting that the judge has halted the lawsuits until March after Toyota and its lawyers have had extra time to try and settle the cases.
According to the article, Toyota is looking to take care of the cases out of court with an "intensive settlement process." Having already paid out $1.6 billion in "economic loss" suits, this latest settlement process is aimed at the wrongful death and personal injury cases allegedly associated with unintended acceleration. A hearing for the settlements will be held on January 14 with conferences on the matter commencing in February. There is no word as to when lawsuits may start back up if settlements can't be agreed upon.

Toyota reaffirms commitment to body-on-frame SUVs

Toyota sold 121,055 Highlander CUVs in 2012, according to Automotive News. By comparison, it sold 78,457 examples of four different body-on-frame, truck-based SUVs (4Runner, FJ Cruiser, Sequoia and Land Cruiser). One could argue then, that the traditional SUVs aren't pulling their weight from a sales perspective. Yet that isn't stopping Toyota from reaffirming its commitment to a segment that has seen its former champions - Ford, General Motors and Chrysler - abandon it with alarming speed. Ford and GM still offer body-on frame utilities, but only in the very largest offerings, catering to seven or even eight passengers. Everything outside of the Expedition or Tahoe rides now on a unibody.
Toyota's decision to stick with the technology is good news if you're in the market for smaller SUVs that are still capable of heading well off the beaten path. Outside of the Jeep Wrangler, Grand Cherokee (a unibody) and perhaps Nissan Xterra, there's not much in terms of capable SUVs between $20,000 and $50,000. As the Toyota brand's US head, Bill Fay, says, "Clearly, the trend has shifted, but there is still an owner base that is interested in these vehicles."
We don't doubt Fay on that, but it may also be somewhat telling that Toyota's SUV lineup is aging, and we haven't seen or heard much about replacement models in the pipeline. Admittedly, the 4Runner (pictured) has been facelifted for 2014, but it's mostly cosmetic in nature. Despite Toyota's posturing, we still expect its body-on-frame lineup to thin in the coming years as sales dwindle and escalating fuel-economy standards make business cases even tougher. Here's hoping that Toyota manages to keep at least one rough-and-tumble SUV in its lineup in the coming years.
