Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.

Toyota FCV puts hydrogen fuel cell twist on ALS Ice Bucket Challenge

You've probably seen your fair share of Ice Bucket Challenge videos online this week, which are meant to raise money to fight amyotrophic lateral sclerosis (ALS), often called "Lou Gehrig's Disease." Hopefully, you've seen ours. We've watched a lot of these videos, but haven't seen one that makes an alt-fuel point quite like a new video from Toyota. Julie Hamp, the CCO of Toyota North America, lost a sister-in-law to ALS last year, so for her the cause is personal. Instead of just dumping icy-cold water on her head, Hamp uses water from the FCV fuel cell vehicle parked next to her. Because, of course, a hydrogen fuel cell car emits nothing but water vapor. Toyota didn't run a lot of hydrogen through the car to collect water, it just got enough to top off the ice bucket. Using the water emissions from a hydrogen vehicle in a creative way is not a new trick. Two years ago, the California Fuel Cell Partnership made the point that you can drink the emissions (just like Mercedes-Benz did earlier this year), but admitted that "fuel cells produce about the same amount of water as gasoline vehicle – about 1/3 cup for a full day of driving." Still, for a good cause, we'll accept the mix of tap water and "emissions." Check out the video below, if you haven't had enough already. This content is hosted by a third party.

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.
