NHTSA closes Ford F-Series Super Duty steering probe without recall

The National Highway Traffic Safety Administration's investigation into 2008 Ford F-250 and F-350 Super Duty pickups, which was originally opened last year, has now ended without a recall. NHTSA was looking into steering failures on some 336,000 trucks.
The issue rested with the steering gear - NHTSA received five complaints of failures - which was redesigned in 2005. According to the report on the matter, investigators "found evidence of broken sector shaft gear teeth and piston damage consistent with incidents of single event overload."
NHTSA investigators, however, "found no evidence of fatigue or material property defects in any of the fractures. Analysis of complaint rates by vehicle build month showed no patterns indicating potential manufacturing quality issues and no difference before and after Ford introduced design changes to the input shaft and sector shaft seals in July 2007 to address potential leak concerns," according to the report, obtained by The Detroit News.

Ford C-Max Solar Energi takes a recharging station wherever it goes

Companies ranging in size from small startups to major automakers have been experimenting with solar-powered charging stations for EVs and plug-in hybrids. And, of course, people have been powering vehicles with onboard solar panels for quite some time, too. Still, Ford's new C-Max Solar Energi Concept shows the promise of a truly practical implementation of solar on a production vehicle, and it may not be as far off in the future as we had thought.
As we reported a few days ago, the Solar concept makes use of a "concentrator lens" that focuses sunlight onto the Ford's roof-mounted solar panels. The special lens follows the rays of the sun to maximize the amount of charge being fed to the batteries of the car, taking about a day to fully charge the 21-mile, all-electric range of the C-Max Energi. Ford data suggests that combination might be enough to power 75 percent of all trips made by a statistically average driver. In turn, using the sun to power a vehicle could reduce yearly C02 emissions by up to four metric tons when compared with the driver of an average gasoline-powered sedan.
We've got live images of the C-Max Solar Energi Concept, jauntily tilted on its display to best present it's signature solar panels, straight from the CES floor.

Is it time for American carmakers to give up on dual-clutch transmissions? [w/poll]

Last week, in the midst of Detroit's first days seeking relief in Chapter 9 of the bankruptcy code, Automotive News contributor Larry P. Vellequette penned an editorial suggesting that American car companies raise the white flag on dual clutch transmissions and give up on trying to persuade Americans to buy cars fitted with them. Why? Because, Vellequette says, like CVT transmissions, they "just don't sound right or feel right to American drivers." (Note: In the article, it's not clear if Vellequette is arguing against wet-clutch and dry-clutch DCTs or just dry-clutch DCTs, which is what Ford and Chrysler use.) The article goes on to state that Ford and Chrysler have experimented with DCTs and that both consumers and the automotive press haven't exactly given them glowing reviews, despite their quicker shifts and increased fuel efficiency potential compared to torque-converter automatic transmissions.
Autoblog staffers who weighed in on the relevance of DCTs in American cars generally disagreed with the blanket nature of Vellequette's statement that they don't sound or feel right, but admit that their lack of refinement compared to traditional automatics can be an issue for consumers. That's particularly true in workaday cars like the Ford Focus and Dodge Dart, both of which have come in for criticism in reviews and owner surveys. From where we sit, the higher-performance orientation of such transmissions doesn't always meld as well with the marching orders of everyday commuters (particularly if drivers haven't been educated as to the transmission's benefits and tradeoffs), and in models not fitted with paddle shifters, it's particularly hard for drivers to use a DCT to its best advantage.
Finally, we also note that DCT tuning is very much an evolving science. For instance, Autoblog editors who objected to dual-clutch tuning in the Dart have more recently found the technology agreeable in the Fiat 500L. Practice makes perfect - or at least more acceptable.
