Ford files patent for 11-speed transmission

The automatic transmission seemed limited to three or four gears for decades, and then the automotive world slowly started to see more ratios becoming available. Today, seven-, eight- or nine-speed gearboxes have become rather common. Ford even has an automatic with 10 gears on the way for the future F-150 Raptor. The Blue Oval might not be done yet, though, because the company also now has a patent on an 11-speed box. The filing, which was discovered by AutoGuide, says this idea "produces eleven forward speed ratios and one reverse speed ratio by selective engagement of three shift elements in various combinations," and the company outlines three different ways of making this possible. The advantage of adding one more ratio is that the gearbox should be able to keep the revs in the ideal portion of the engine's torque curve even longer. Obviously, automakers patent ideas constantly, and applying for one is no guarantee that the tech ever arrives on the market. Conversely, these documents provide a tiny glimpse at one of the brand's focuses of development. If you're mechanically minded or just curious, you can read the entire application here for the technical nitty-gritty.

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.

Ford confirms 1.5-liter EcoBoost four-cylinder engine for 2014 Fusion

Earlier this week, reports were swirling 'round the internet about the 2014 Ford Fusion getting a new 1.5-liter three-cylinder EcoBoost engine. That was... half correct. Ford today confirmed that the 2014 Fusion is, in fact, getting a new 1.5-liter EcoBoost mill, but it has four cylinders, not three.
The new 1.5-liter engine will be the fifth EcoBoost powerplant from Ford Motor Company. Initially to be built at the automaker's Craiova, Romania plant, it will also be offered in the Fusion's twin, the Mondeo, in other markets. This engine will debut at the Shanghai Motor Show next month, and the 1.5-liter is of particular importance in the Chinese market - there is significant tax relief in the People's Republic for vehicles powered by engines with a capacity of 1.5 liters or less.
At a media briefing Thursday, Ford declined to divulge exact power or fuel economy numbers, though Joe Bakaj, vice president of powertrain engineering, told Autoblog that power output should be similar to that of the current 1.6-liter inline-four, and that overall efficiency will be "better than the 1.6." Our earlier report stated that the 1.5-liter four will produce 177 horsepower and 177 pound-feet of torque - losses of 1 hp and 7 lb-ft versus the 1.6-liter engine. Ford states that the 1.5-liter four will feature many of the same technologies used on the company's 1.0-liter EcoBoost inline-three, including an integrated exhaust manifold that recaptures much of the engine's heat.
