Total auto recalls already on record pace in 2014

If you've noticed that there have been more recalls than usual this year, you may be on to something. According to a report from the National Highway Traffic Safety Administration, the US market is on pace to break a record for recalls. In 2013, 22 million cars were recalled. We're only a third of the way through 2014, though, and we've already halved that figure, with 11 million units recalled. That's wild.
Considering the past few months, it shouldn't be a surprise that General Motors is leading the charge, with six million of the 11 million units recalled coming from one of the General's four brands. Between truck recalls, CUV recalls and the ignition switch recall, 2014 hasn't been a great year for GM.
Other recall leaders include Nissan (one million Sentra and Altima sedans), Honda (900,000 Odyssey minivans), Toyota (over one million units in a few recalls), Volkswagen (150,000 Passat sedans), Chrysler (644,000 Dodge Durango and Jeep Grand Cherokee SUVs) and most recently, Ford (434,000 units, the bulk of which were early Ford Escape CUVs). So while it's been a bad year for GM so far, its competitors aren't doing too well, either.

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 wants smart cruise that's speed and grade sensitive

Ford is working to make adaptive cruise control even smarter and more economical for future vehicles. The automaker now has a patent (pdf link) on a system to use information on the grade of the road, traffic data, and a driver's preferences to eke out better fuel mileage over a journey. This solution would essentially put a little hypermiling right into a model's software. The Blue Oval's patent refers to this tech as "route navigation with optimal speed profile," and the system starts by splitting the way to the driver's ultimate destination into many smaller pieces. Each one is analyzed based on GPS data, and traffic info is also constantly updated. Based on the occupants' preferred travel time, all this info is combined to figure out the most efficient speed for each leg of the journey. All of these calculations are actually more than the car's computers can handle, so some of the math is offloaded to a cloud-based network. According to Ford, some of the benefits come when tackling hills while diving. Maintaining a single speed when going up and down steep grades isn't the most efficient method, but current technology can't easily make the necessary adjustments. This system uses the GPS data to adapt the vehicle's speed and leave the situation with better fuel economy. Ford is currently making major investments into autonomous driving technology and has some prestigious partners. While the patent documents don't specifically mention the optimal speed profiles for driverless vehicles, they seem like a natural fit. Over the course of an entire trip, the fuel economy gains would likely be even greater than over a few miles on a relatively flat interstate.
