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.

Amelia Island 2013: 50 years of the Ferrari-slaying Ford GT40

Originally developed with the sole purpose of being a Ferrari rival to compete at the 24 Hours of Le Mans, the Ford GT40 became a prominent racing machine in the 1960s in both Europe and the US. Not wanting to leave such an important car out of the fun, the 2013 Amelia Island Concours d'Elegance also took time out from its other celebrations to recognize the 50-year anniversary of the GT40.
Over its short lifespan, the GT40 was offered in a handful of configurations, but the classic short-tailed (Mk I and Mk II) bodystyles were well represented... especially in Gulf livery. James Glickenhaus (of Ferrari P4/5 fame) had his bright yellow Mk IV in the field, and there were several others in this bodystyle, including one that has seen plenty of time on the track judging by its chipped-up nose.
As a fitting statement for the car's lengthy racing history, GT40 Chassis Number 1075 won this year's Concours de Sport award. This car took home the checkered flag at Le Mans in 1968 and 1969, and racked up a total of six wins in just 11 races.

United States drivers buying fewer Mexican-made cars

Crossovers and pickup trucks are not only growing in market share, they're also more profitable than cars. A crossover on the same platform as a sedan retails for thousands more, despite similar components. It's one of the reasons we've seen automakers rapidly shifting production of their sedans and hatchbacks to Mexico, where cheap labor preserves the thin profit margins on these inexpensive vehicles. But as the market continues to shift in the United States, Mexico is getting burned by its lack of product diversity. The country's auto exports, which are heavy on cars, suffered a 16-percent drop last month, Automotive News reports. In total, year-over-year exports fell from 233,515 to 197,020 last month, while year-to-date exports are down by 7.4 percent, from 922,029 to 854,118. The number one culprit? America – which usually accounts for 75 percent of Mexico's exports – and its appetite for crossovers and pickup trucks bolstered by cheap gas prices. While Mexico does build some light truck models – AN specifically calls out the Ram 2500, Honda HR-V, GMC Sierra, and Toyota Tacoma as export leaders – the vast majority of vehicles rolling out of its factories are sedans and hatchbacks. In fact, the three biggest drops in Mexican exports came from companies whose south of the border factories only build cars – Ford (Fusion/Lincoln MKZ and Fiesta), Mazda (Mazda3), and Volkswagen (Golf and Jetta). Mexican Automotive Industry Association President Eduardo Solis told AN the export shortfall will likely be sorted out sooner rather than later, thanks to a pair of new factories – a Kia car factory and an Audi SUV plant – that are coming online by year's end. The two facilities will add around 100,000 vehicles to the country's export totals, which Solis said should leave the industry on the verge of breaking another export record in 2016. But how sustainable will these record-breaking years be? Slapping an "Hecho en Mexico" sticker on a new German SUV won't be enough to change the fact that Mexico's product mix is tilted too heavily towards body styles that are not growing in volume. Mexico's record-breaking export years probably aren't at an end, but we'd argue they're certainly under threat.
