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.

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

Weekly Recap: GM posts solid profits, not looking for partners

General Motors is not looking for partners. It's big enough already. So says CEO Mary Barra, who shot down overtures from outspoken Fiat-Chrysler chief Sergio Marchionne this week. Barra said GM will look to find scale within its operations, rather than through outside partners. "We think there's tremendous opportunity for us within the business as we look at efficiency measures, as we look at truly achieving the scale that we should have, because we're already in that top tier of the auto industry among the largest OEMs," she said. Barra added: "We have a very well-articulated plan. We're in the middle of executing that, and we're not going to entertain anything that might distract us from accomplishing that." Her remarks came in the wake of Marchionne's provocative comments in March. He expects a wave of industry consolidation and said he's open to teaming with Ford or GM, calling it "technically feasible." Because of its smaller size, FCA would likely stand to gain more from a partnership than GM or Ford. The Blue Oval isn't interested in teaming with Fiat-Chrysler, either. "We have no other plan or interest then to continue to accelerate our One Ford plan, deliver product excellence and drive innovation in every part of our business," a spokesperson said. GM, the largest US automaker, announced a $945-million first-quarter profit on Thursday and posted its best earnings performance in North America since 2009. Earlier in the week, GM confirmed it had sold 2.4 million vehicles around the world in the quarter, ranking behind Toyota (2.52 million) and Volkswagen (2.49 million). Other News & Notes SUVs, EVs shine at Shanghai Motor Show SUVs and electric vehicles grabbed the spotlight at the Shanghai Motor Show this week as companies vied for attention in the world's largest car market. Notably, Honda's Concept D previewed the company's future flagship SUV that's being developed for China, Mercedes rolled out a BMW X4-fighting GLC Coupe concept and Chinese company Qoros debuted its 2 plug-in SUV concept. Nissan, Volvo and several others also showcased utility vehicles in Shanghai. Automakers are rushing to take advantage of the crossover craze in China. The market for locally-produced SUVs grew 50 percent in the first quarter, according to IHS Automotive research, which called the show a "launch pad" for new utility vehicles. Even though SUVs are popular, IHS predicts their growth rate will slow, and sedans account for more sales volume in China.
