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.

2015 Chrysler 200 snags EPA ratings of 18 mpg city and 29 highway

While Chrysler hasn't officially announced fuel economy figures for its new 200 sedan, the information for one model has just leaked out thanks to the US Department of Energy's FuelEconomy.gov website. It certified the 200 with the 295-horsepower and 262-pound-feet 3.6-liter Pentastar V6, nine-speed automatic and all-wheel drive as getting 18-miles-per-gallon city, 29-mpg highway and 22-mpg combined.
Last year's front-wheel drive 200 with a less-powerful version of the Pentastar was rated at 19-mpg city, 29-mpg highway and 22-mpg combined. That means that buyers are getting more power and all-wheel drive traction at almost no loss in economy. However, compared to current, all-wheel drive sedan competitors, the Chrysler comes in the middle. The Ford Fusion with all-wheel drive with the 2.0-liter EcoBoost four-cylinder has 240 hp and 270 lb-ft of torque is somewhat down on power but bests it in economy at 22-mpg city, 31-mpg highway and 25-mpg combined. The current Subaru Legacy 3.6R loses in both metrics with 256 hp and 247 lb-ft and a rating of 18-mpg city, 25-mpg highway and 20-mpg combined. However, Subaru claims the next generation with the same engine will boast 20-mpg city, 28-mpg highway and 23-mpg combined. But these numbers are just estimates from the automaker at the moment, and they haven't yet been certified by the EPA yet.
The numbers for the four-cylinder and front-wheel drive 200 drivetrains are not yet available, but Chrysler has been promising the sedan gets an estimated 35-mpg highway with the 184-hp and 173-lb-ft Tigershark 2.4-liter four-cylinder engine. We won't know for sure until it's certified, but we'll keep you posted.

Chrysler recalling 382k Ram HD diesel pickups, 184k SUVs

Between GM's ignition switches and Takata's airbags, it's been a big year for recalls, but they keep rolling in. The latest comes from Chrysler, which has announced a pair of recalls for certain heavy-duty pickups and SUVs.
The first issue revolves around the 6.7-liter Cummins diesel engine available in the 2010-2014 Ram HD trucks, including 2500 and 3500 series pickups as well as 4500 and 5500 series chassis cabs. In the affected units, "a terminal connector near the fuel heater may be subject to friction-induced corrosion," according to the first of the two announcements from Chrysler below.
The problem could result in overheating and fuel leakage. Chrysler launched its investigation following cases of overheating, none of which actually started a fire, much less an injury or accident. As a precautionary measure, however, Chrysler is instructing service technicians to replace the terminals on an estimated 381,876 Ram units around the world - the vast majority of those (314,704) registered in the US, another 59,432 in Canada, 1,803 in Mexico and 5,937 abroad.
