Toyota close to unveiling 4th-generation Prius hybrid

The timing isn't perfect, but Toyota is getting close to rolling out the next generation of its Prius gas-electric hybrid car. Low gas prices have depressed sales of hybrids, with Prius sales falling 14 percent in the first five months of this year. The US government expects gasoline to average $2.44 a gallon this year, compared with $3.36 a gallon in 2014. North American CEO Jim Lentz said Thursday that the new Prius will get better gas mileage than the old one and is better looking. He cautioned that reports of a 15-percent improvement in fuel economy are probably too high. The current Prius gets an estimated 50 mpg in combined city and highway driving. He also said the new version has a lower center of gravity for better handling. Lentz said Toyota, the market leader in hybrid sales, will continue to develop new hybrids even though sales of alternative-fuel cars as a segment are down about 15 percent for the year. "With lower fuel prices, it's having an impact on the entire segment," he said. "But long term, it's still the player. We've seen these rises and falls in fuel prices in the past. " Lentz wouldn't say exactly when the fourth-generation car will debut. The Prius was last revamped six years ago in 2009. Lentz made his remarks Thursday at a groundbreaking ceremony for a $126 million expansion of its technical center on two campuses near Ann Arbor, MI. The moves will bring about 335 jobs to the area from other Toyota locations. The AP contributed to this report.

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.
