NHTSA opens safety investigations into Toyota, GM and Honda crossovers

The National Highway Traffic Safety Administration is evidently keeping itself very busy these days, as the federal agency has just announced it is launching or renewing investigations into Toyota, Honda and General Motors crossovers.
2006-2008 model year Toyota RAV4 crossovers are under review for allegations of rear tie-rod rust which can result in failure. NHTSA also said it is probing some 35 complaints about 2005 Honda Pilot models with inappropriate activation of the vehicles' stability control system. The alleged malfunction can cause the vehicles to slow down or stop in bad unsafe situations. At the moment, NHTSA is reviewing a petition regarding the Pilot issue, a move that will determine whether it needs to open a full-blown investigation.
In addition, Saturn Outlook and GMC Acadia three-row crossovers built in 2007-2009 are getting looked at for "loss of low beam headlamp" function. One complainant said the wiring in his Outlook overheated and melted. NHTSA says it has received 415 complaints about the problem and a GM spokesman confirmed that the automaker already started a "Customer Satisfaction Program" in December to address the issue.

Toyota restructuring US operations, possibly moving to Texas

According to multiple sources familiar with the matter, Toyota is poised to announce Monday that it is restructuring its US operations, which may include plans to relocate some of its operations to Texas. Toyota Motor Sales has been located in California since 1957, and is responsible for North American sales, marketing, and distribution for Toyota, Lexus and Scion. According to Toyota literature, its Torrance operations presently employs 6,156 workers and represents a $2.3-billion investment.
Workers in Toyota's Torrance offices were abuzz about the possible relocation to Texas. One young offspring of a Toyota employee even posted to Twitter that her parents warned about the upcoming move, and she said she's refusing to go.
Rumors at one point had Toyota settling in Richardson, TX, just outside Plano. But Autoblog talked to Richardson Mayor Laura Maczka, who said she would be thrilled if that were true, but has not heard anything on the subject. Autoblog also emailed with Bill Sutherland, a city councilman in Torrance, CA, who said, "To date the only info I have is what I have read in the paper expecting a press release Monday."

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.
