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.

Coming Toyota Supra to forgo hybrid, get a BMW six-cylinder turbo?

For years, almost all of the talk about the Toyota FT-1 concept becoming a resurrected Supra envisioned a hybrid under the hood. And then the latest take on Future Toyota 1 showed up at the 2014 Detroit Auto Show and - although Toyota wouldn't say a word about any engine at all - horizons began to expand. Imaginary fancies were aided by the news that Toyota had partnered with BMW to develop a sports car on the next-generation BMW Z4 platform, which would necessarily mean an engine bay designed to accept an old-fashioned hunk of gas-burning iron-working solo. Car and Driver now turns the whole thing around, reporting that there will be an inline-six with forced induction provided by BMW under the hood. What about that hybrid, though? The report states, "there's currently no indication that the Silk Road cars will offer hybrid options" - 'Silk Road' being the codename for the jointly-developed vehicles. CD makes a point to note that said tidbit came from Germany, not Japan. However, designers at Toyota's Calty studio did tell Automotive News last year that they designed the body with an inline-six in mind, a nod to the Supra's history. Hybrid rumors aren't dead yet, though - remember, we were hearing about all-wheel drive and supercapacitors in May 2014. The coupe is predicted to be a 2018 model, making its appearance sometime in 2017, and be "about 10 percent" smaller than the FT-1 concept. Related Video:

Toyota sudden acceleration class action may cover 22 million owners

A total of 22.6 million current and former Toyota owners have been sent notices that they may be eligible to receive compensation from the automaker for damages related to the unintended acceleration fiasco that has dominated headlines in 2009 and 2010. The total payout may be as high as $1.63 billion, according to The Detroit News.
Steve Berman, a lawyer for the owners, calls the potential deal "a landmark, if not a record, settlement in automobile defects class action litigation in the United States." Still, there's some debate about whether or not Toyota's proposed settlement is fair, as it includes $30 million for safety research and driver education programs - in other words, Toyota seems to be suggesting that drivers need more education on how to drive their correctly working and fully functional vehicles. For those keeping track, Toyota would also be paying lawyer fees of $200 million.
A US District Judge in California is scheduled to hold a so-called "fairness hearing" on June 14 that could decide the fate of this particular settlement. Further courtroom wrangling will be required to hash out any wrongful death suits levied against Toyota stemming from unintended acceleration claims, as those are not part of this class-action suit.
