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 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 recalls 337,000 RAV4s and HS250h models for tie rod failure

UPDATE: The post has been updated with additional information from NHTSA. The Basics: Toyota is recalling 337,000 2006-2011 model year Toyota RAV4 crossovers built between October 31, 2005 and September 7, 2010 as well as 2010 model year Lexus HS250h cars built between July 6, 2009 and August 26, 2010. The Problem: When either an affected RAV4 or HS250h is given an alignment and the tie rod adjustment nut on the rear control arm isn't tightened properly, the threads on the tie rod can start to rust. If this happens, the nut may break off and throw off the alignment drastically and suddenly. This isn't a case of the car simply pulling to one side, either. This would seriously upset the balance of the car and could cause the driver to lose control and crash. This is also the third time these vehicles have been recalled for the same issue. Injuries/Deaths: It's unknown if this control arm issue has resulted in any injuries or deaths. Autoblog reached out to Toyota for more information, but a company representative told us that the company isn't able to discuss injuries or deaths caused by this issue (if any) at this time. Based on information from NHTSA documents, it does not appear that any crashes, injuries or deaths have been attributed to the defect addressed in the current recall. The Fix: The dealer will completely replace the rear suspension assemblies at no cost to the owner. The tie rods and nuts will also be coated in epoxy to prevent future rusting from occurring. According to Car and Driver, the previous recalls involved tightening nuts, coating decent tie rods in epoxy and completely replacing rusted ones. The car magazine reports that further complaints were filed and the company is now replacing all components regardless of condition. If you own one: Toyota will notify owners of affected cars by mail. Owners can also check whether their cars are affected by entering the VIN at safercar.gov/vin. Owners with questions can also reach Toyota customer service at 1-800-331-4331 or Lexus customer service at 1-800-255-3987.
