How platform problems are delaying next-gen Prius

Short-term pain for longer-term gain? That may be the prognosis for the next-generation Toyota Prius, the world's best-selling hybrid. But, hey, the new version might get holiday season debut, now. Toyota is upgrading some of its most popular models and trying to cut long-term costs with components that can be used on multiple models on the new Toyota New Global Architecture platform, Automotive News says. That means more parts that can be used for the Camry, Avalon (not big stretch, since the Avalon is basically a rich man's Camry) and Corolla in addition to the Prius. The downside, of course, is that this takes a bit more engineering and certainly more time. In the case of the Prius, that means pushing back the start of production from next summer to December 2015. But Automotive News also says the Prius may have an all-wheel-drive option. Happy Holidays. The report is in update from Automotive News Europe, which cited folks familiar with the process who were not identified and said late last month that the production of the fourth-gen Prius would be pushed back by about six months as engineers continue to tweak the hybrid powertrain for maximum efficiency. The goal is around a 10 percent improvement in fuel-efficiency thanks to an upgraded powertrain and lower vehicle weight. Toyota spokeswoman Amanda Rice told AutoblogGreen in an email that the company doesn't comment on future products, so we'll just have to keep an eye out.

Toyota recalls power window switches for 6.5 million vehicles [UPDATE]

UPDATE: There was one incident of someone in the US getting a burn to the hand from this issue Toyota spokesperson Cindy Knight tells Autoblog that. "We have 11 reports where part of the door trim and/or switch was burnt," she said. The company isn't aware of any crashes from the problem, though. Because of a potential short circuit in the driver's side power window switch, Toyota is recalling 6.5 million vehicles worldwide, Reuters reports. Of those, the automaker says around 2 million are in the US. The affected models here are: 2007 and 2009 Camry and Camry Hybrid 2009-2011 Corolla 2008-2011 Highlander and Highlander Hybrid 2009-2011 Matrix 2006-2011 RAV4 2009-2011 Sequoia 2009-2011 Tundra 2006-2010 Yaris 2009-2011 Scion xB 2009-2010 Scion xD According to Toyota, the switch might not have received adequate lubricant grease during manufacturing, and over time this could lead to a short circuit. In a worst-case scenario, the part might even overheat, melt and cause a fire. As a fix, dealers will inspect the component on these vehicles and apply heat-resistant grease to it, and any broken examples will have an internal circuit board replaced. Toyota already issued one recall for this problem in 2012 when it had to repair 7.5 million vehicles globally from the 2007-2009 model years, including 2.5 million in the US. These latest models had the grease applied in a different way.

The involved vehicles include certain: 2007 and 2009 Camry and Camry Hybrid 2009-2011 Corolla 2008-2011 Highlander and Highlander Hybrid 2009-2011 Matrix 2006-2011 RAV4 2009-2011 Sequoia 2009-2011 Tundra 2006-2010 Yaris 2009-2011 Scion xB 2009-2010 Scion xD The Power Window Master Switch in the involved vehicles may have been manufactured with insufficient lubricant grease. If not enough grease is applied, under certain conditions the switch may develop a short circuit that can cause the switch assembly to overheat and melt. A melting switch can produce smoke and potentially lead to a fire. Toyota previously recalled certain 2007-2009 model year vehicles for a similar condition.

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.
