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.

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.

1947 Chevy rat rod pickup leaves rubber and smoke in its wake

Cool comes in multiple flavors. One one hand, we have the sophisticated attraction of svelte design and the efficient use of power. Of course, on the other hand there is the allure of being the bad boy and going against the grain. That is part of the appeal of rat rods. Ideally, they are built without rules to an owner's specific tastes, and this widened and heavily modified 1947 Chevrolet pickup rod is a perfect example of that spirit.
Coming down the highway with a bent grille, rusted body and pouring smoke, it looks like the pickup from hell. It backs up the looks with some very impressive mechanicals too. Owner Troy Gubser says that the truck packs a Ford Power Stroke diesel with to 42 pounds of boost that runs out of 8-inch exhaust stacks at the back. He claims it managed 505 horsepower and 885 pound-feet of torque on the dyno. To harness all that power, this hot rod has a ZF five-speed manual gearbox with a ceramic clutch and short-throw shifter. Plus, it has cool little features like a doorbell on the tailgate that operates an air horn.
You might not expect a truck like this to actually be useful, but it has a fifth wheel coupling to haul an RV around drag races and car shows. The air suspension also probably keeps the ride fairly comfy when Gubser wants it to be. Scroll down to check out this beastly rat rod pickup and watch it engage in some diesel drag racing. Warning, there is some NSFW language.
