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.

Galpin Auto Sports and Fisker turn the Mustang into a Rocket in LA [w/video]

Galpin Auto Sport and Henrik Fisker made big promises about the Rocket before its debut at the Los Angeles Auto Show today, calling it the "ultimate American muscle car." Now that this 725-horsepower carbon-fiber Ford Mustang has officially been revealed, we've now got a chance to see if their vision backs up all the bluster. The Rocket is based off the latest 2015 Mustang, but the entire exterior design has been substantially reworked by Fisker. "This is a project born out of passion, it's a dream come true, to have the opportunity to 'touch' a Mustang and apply my design ideas to it," he says in the model's announcement. The biggest changes come up front, where Fisker has added a gaping hexagonal grille with a polished bar running and two nearly hidden driving lights at the top corners. Long nostrils run down each side of the hood, taking their inspiration from the 1968 Shelby GT500. The Rocket's design also emphasizes its scalloped sides, which run back to functional ducts at the rear to cool the Brembo Grand Turismo brakes. When checking out the Rocket from the rear, it's easy to spot the wider fenders that are beautifully blended into the integrated spoiler. The interior has been left mostly alone beyond some eye-grabbing red leather and carbon-fiber trim. Under the hood, Galpin spokesperson Nathan Hoyt has confirmed to Autoblog that the Rocket employs a 5.0-liter V8 with a Whipple supercharger which can be called to attention with a six-speed manual gearbox. It took only a few months for the vehicle to go from conception to reality. Fisker showed Galpin President Beau Boeckmann early sketches at this year's Pebble Beach Concours d'Elegance, and the two parties went from there. "When Henrik showed me his ideas, I got chills - it's literally the most beautiful Mustang I have ever seen," says Boeckmann in the company's release. Production is set to begin in December, with deliveries starting in early 2015. There's no set production total in mind for now, but Hoyt tells Autoblog that the price will be "just over $100,000."

McLaren, Koenigsegg, Toyota, Ford, Dodge and Corvette Lego kits announced for 2021

Lego has announced a slew of car-themed sets for 2021. The six kits comprise nine vehicles and fall under the brick pusher's Speed Champion line of official OEM-licensed kits. News of their arrival comes from German toy retailer JB Spielwaren's pre-order listings, which show three single-car sets and three dual-car sets of matched marques. Starting with the McLaren Elva roadster, the kit consists of 263 pieces and is finished in blue. It seems to have a difficult time capturing the curves of the real-life Elva, but there's only so much you can do with a bunch of plastic blocks. Lego has made several other McLaren kits before, including the Senna, 720S, and a more advanced Senna GTR for the Technics line. Next up is the Koenigsegg Jesko, made up of 280 pieces and finished in white. Though the real-life Jesko is still curvy, this kit does a better job of replicating its aggressive maw, vents and cantilevered rear wing. Rounding out the single-car sets is the 299-piece Toyota GR Supra in yellow. This marks the first time Toyota has lent their license to Lego. Again, it struggles a bit to represent the curvy Supra, relying on printed details like logos and headlights to identify. On the other hand, the Chevrolet two-car does a stupendous job with the 1968 Corvette. The C3 is instantly recognizable as such. The C8-R race car it's paired with suffers from the same issues as some of the previous cars, though. The set contains 512 pieces, and funnily enough the C8 driver has short hair while the C3 driver sports a period-correct wavy mane. The next set is a 627-piece Mopar-themed pair, including a purple (Plum Crazy?) 1970 Dodge Challenger T/A and an SRT top fuel dragster. The race car is spot on, but the Challenger was probably tough to make given the width restrictions. It looks a couple of pegs too narrow compared to the wide proportions of the real deal. Last but not least, the Ford set contains a Bronco R and Ford GT Heritage Edition. Consisting of 660 pieces, the set does an excellent job of representing both cars. The GT looks faithful in its Gulf livery, and the Bronco R looks more like a real Bronco than the actual Bronco R race truck. All in all, it's always fun to see more Lego sets with real cars, and we're glad to see more manufacturers added to the roster. The single-car sets are recommended for ages 7 and up, while the double-car sets have an 8 years and up rating. Price in U.S.
