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.

Auto execs surveyed say VW, BMW most likely to grow

A new survey of top global automotive executives indicates both Volkswagen and BMW are the most likely to grow their market share over the next five years.
Tax advisory firm KPMG LLP has released its 14th annual Global Automotive Executive Survey, which includes responses from over 200 executives. A total of 81 percent of respondents said they expect to see Volkswagen make gains, compared to 70 percent last year. BMW, meanwhile, saw 70 percent of those surveyed say they believe the company will increase its market share. That's a jump of 7 percentage points over last year. This is the first time in the history of the survey that BMW has claimed the second-place spot.
Meanwhile, Hyundai has seen its perceived market share potential slacken for the third year in a row. Around 61 percent of those surveyed predicted gains for Hyundai, down from 63 in 2012. Toyota also has a surprising year, but for just the opposite reason. While the manufacturer had slipped in ranking since 2011, it enjoyed the largest increase of any company in the 2013 survey, jumping to 68 percent from 44 percent last year.

Toyota sees Camry share loss despite predicting increasing sales

Toyota may be set to lose share the midsize sedan market. While speaking with Automotive News, Toyota North America CEO Jim Lentz said that if his company kept pace with the current swell in the market for family four doors, Toyota would need to sell around 500,000 Camry models. "I'm not sure we can do much more than 400 [thousand] today," Lentz said.
But that doesn't mean Camry sales are shrinking - on the contrary, Lentz thinks Toyota will likely sell more Camry units in 2013 than it did in 2012, it's just that the company isn't keeping pace with segment's current explosion in popularity. Industry wide, midsized sedan sales have increased by 20 percent. "Are we going to lose [Camry] share? Probably so," Lentz said, "but we will continue to grow in raw volume."
Toyota sold 404,886 Camry units last year, and the company just revised its 2013 sales objective from 2.18 million units earlier this year to 2.2-million plus units, so while things are looking up for the brand and Camry sales may be on the rise, Toyota may not have the muscle to keep up its share in the sedan segment. Whether that's because of a production bottleneck or a predicted sales ceiling isn't clear. We've got a call in and will update this news item if/when we learn more.
