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, Ford and Honda again top Consumer Reports Car-Brand Perception Survey

Consumer Reports has released its annual Car-Brand Perception Survey, and the list looks awfully familiar. The top six brands are identical to last year's results, with Toyota, Ford and Honda continuing to occupy the podium. All told, Toyota walked away with 133 points, putting it 15 ahead of second-place Ford. Honda jumped 26 points this year, narrowing Ford's lead to just four points in total.
Consumer Reports polls buyers from across the country on how they see multiple brands in seven categories, including quality, safety, value, performance, design/style, technology/innovation and environmentally friendly/green. Researchers then combine the findings to come up with the total brand score.
While value and performance remain important to buyers, CR found quality and safety are still on top when it comes to significance. Scion and Mitsubishi found themselves at the bottom of the pack with the worst score of all, tied at just six points. Ram, Fiat and Mini filled out the lowest five with scores of seven, eight and 10 points, respectively.

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.
