Which is more fuel efficient, driving with a pickup's tailgate up or down?

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.

Ford, GM still doing new business with Takata amidst airbag crisis

Lengthy vehicle development times make it difficult for automakers to cut and run from the supplier. You might expect automakers to be fleeing any connection with beleaguered supplier Takata in the wake of the company's exploding airbag inflator crisis. After all, with a Senate hearing, pending lawsuit, plummeting stock value and demand for a national recall, the tier-one supplier isn't at its strongest right now. However, years of cooperation mean that automakers are standing by Takata, and necessity may be playing a role, as well. About 39 percent of Takata's business comes from airbags, and seatbelts make up another significant chunk of the operation too, says Bloomberg. The long-term relationships and lengthy vehicle development times make it difficult for automakers to cut and run from the supplier. "Takata has so much product breadth that I don't really see that they could just disappear," said AutoPacific analyst Dave Sullivan to Bloomberg. For example, Takata helped develop the unique front center airbag with General Motors in models like the Chevrolet Traverse and Buick Enclave. Outside of safety tech, it is also a partner with Ford on the adaptive steering system available on the upcoming 2015 Edge. These long-lasting partnerships make change difficult now that there's a problem. According to Reuters, automakers claim it would take a year or longer to set up with a different supplier for replacement airbag inflators. Switching to a completely different part for the repairs might not be a viable option either, because of the engineering time needed. BMW is taking action, though. According to Reuters, the Bavarian brand is working with the supplier to move inflator production from Monclova, Mexico, to a Takata factory in Freiburg, Germany. The Mexican plant may be the source of some of the faulty parts. News Source: Bloomberg, ReutersImage Credit: Jens Meyer / AP Photo BMW Ford GM Safety Takata airbag recall

Consumer Reports: Ford Fusion fun but flawed; Mitsubishi i-MiEV slow, chintzy [w/videos]

Waiting for a Ford compliment from Consumer Reports these days is like waiting for a low-cost new product from Apple. So we weren't really expecting a glowing review of the 2013 Ford Fusion when CR got its hands on the car. The institute's crew bought three different versions of the Fusion (Hybrid, 1.6-liter EcoBoost and a Titanium with the 2.0-liter EcoBoost) to put through its barrage of tests, and while we aren't too surprised by some of the findings, they're still interesting nonetheless.
CR praises the Fusion for its "eye-catching" design and says that the sportier Titanium trim level is the best-handling midsize sedan they've ever tested, but that's about where the good news ends for Ford. The Fusion Hybrid also posted the best-ever fuel economy CR has recorded in a midsize sedan, but the only problem is that their number was 39 miles per gallon combined - far less than Ford's 47 mpg rating for city, highway and combined. As expected, CR also dinged the Fusion for its MyFord Touch, but some of the other gripes about the car include a cramped cabin and poor fit and finish.
Other Ford products tested this time around include the Focus Electric and C-Max Hybrid. Like the Fusion, CR's observed fuel economy of 37 mpg for the C-Max fell well short of Ford's advertised 47-mpg rating, and both cars were criticized for the use of MyFord Touch. CR notes that the Focus Electric's interior is also cramped, with the battery pack taking up a lot of cargo space.
