Toyota FCV Concept comes one step closer to reality

When Toyota first conceptualized a gasoline-electric hybrid vehicle for mainstream Americans to drive, the initial response was pretty skeptical. Still, through relentless engineering and solid product after solid product, Toyota has built the Prius brand into the dominant force in the hybrid car market.
Something like that plan of attack is what the Japanese company is preparing for hydrogen fuel cell vehicles, as well, and that attack is seeing a critical salvo fired today with the debut of this FCV Concept at the Tokyo Motor Show.
Though there's nothing substantive to be said about rumors of a 300-mile range or a sticker price around $50,000, the FCV concept does offer a few technical details. The sharp-beaked concept makes use of two high-pressure hydrogen tanks and boasts a power output density of three kilowatts per liter.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

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.
