Aging Prius, dropping gas prices putting hurt on hybrid, EV sales

"As Prius represents by far the biggest chunk of the hybrid marketplace, where Prius goes, the segment goes," - Ed Kim, Autopacific
Fuel prices in the US have been tumbling for the last several weeks, with the average price of a gallon of gas at $3.120 as of October 20, according to the US Energy Information Administration. That price reflects a serious recent drop from $3.299 on October 6. Reports have even suggested that those low numbers might not change for a little while, perhaps as long as years. While drivers certainly love paying less at the pump, the change may be hurting the market for more fuel-efficient models, including the Toyota Prius.

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.

Ford tumbles to second worst in Consumer Reports reliability survey, list dominated by Japanese [w/video]

It's no secret that MyFord Touch has had its share of problems since being introduced, but the most recent reliability survey from Consumer Reports shows just how much this infotainment system has affected Ford. Just two years ago, the automaker was in the top 10 for the institute's reliability rankings, but since then, it has tumbled to the second-lowest rung just above dead-last Jaguar. In addition to MyFord Touch, CR also attributes a handful of new products that have had issues right out of the gate.
Compiled from 1.2 million subscriber surveys, this year's auto reliability survey heavily favors Japanese automakers, with eight of the 10 spots hailing from Japan. Toyota brands grabbed the top three spots (Scion, Toyota and Lexus - in that order) with Mazda, Subaru, Honda and Acura filling the next four spots. The only non-Asian automaker cracking the top 10 was Audi at number eight.
Audi climbed a total of 18 spots from last year, and Cadillac and GMC round out this year's top gainers breaking into the top 15. Helping Cadillac's upward movement, the CTS Coupe was named the most reliable domestic car. Lincoln, Volvo and Chrysler join Ford on this year's biggest loser list.
