Toyota's Lentz says fuel cells are the future, not EVs

Toyota is not bullish on EVs. That comes from the company's North American CEO, Jim Lentz, who said the company will focus not on electrification, but on continued hybridization with a long-term focus on hydrogen fuel cells.
Lentz questioned the long-range ability of EVs, saying that Toyota feels "there are better alternatives, such as hybrids and plug-in hybrids, and tomorrow with fuel cells." Lentz spoke about Toyota's focus on hydrogen following Forbes Brainstorm Green conference and barely a week after a battery deal between Tesla and Toyota ended, according to Automotive News.
That deal provided for 2,500 battery packs for the Rav4 EV. While valuable to Toyota, the deal "was never about open-ended volume," Lentz said. "It was time to either continue or stop. My personal feeling was that I would rather invest my dollars in fuel cell development than in another 2,500 EVs."

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.

Toyota mulling more Tundra, Tacoma capacity in TX

Toyota may be expanding its pickup truck production at its San Antonio, TX factory following calls from dealers for more Tacoma and Tundra models, according to a new report from Automotive News.
The San Antonio plant is currently able to produce 250,000 trucks on two shifts with overtime, while a secondary facility in Tijuana, Mexico can build an extra 50,000 Tacomas. Despite this capacity, and the fact that Tundra is a slow seller relative to the full-size trucks from Ford, Ram and Chevrolet/GMC (not to mention the Tacoma being part of a segment with diminishing sales), Toyota franchisees apparently can't get enough of the trucks.
"Dealers are telling us they could sell more Tacomas and Tundras," said Bill Fay, the general manager of the Toyota Division. "We are evaluating our footprint and capacity." According to AN, Toyota has moved over 248,000 trucks through November.
