Truckmakers squabbling over who can sell Jimmy Fallon a pickup

Snagging a celebrity endorsement is a big deal for automakers, as evidenced by the recent efforts of the Detroit Three to try and woo The Tonight Show's newest host, Jimmy Fallon, into one of their trucks.
After announcing during Wednesday night's show that he was in the market for a pickup truck, Fallon set off a firestorm of efforts on Twitter, with both Ford and Chevrolet petitioning the funnyman to test out a truck. According to Ad Age, Ford recommended the King Ranch edition of its next-generation F-150 while the show was still airing. Chevy, meanwhile, waited until the next morning to pitch a Silverado to Fallon.
The winner of this social media feeding frenzy, though, was Ram. Promoting a variation of its "Guts, Glory, Ram" tagline, the Auburn Hills-based manufacturer created the hashtag #GUTSGLORYFallon. It even went so far as to park a Ram 1500 outside 30 Rockefeller Center in New York, where The Tonight Show is filmed. On the back of the Ram sat a sign, reading "Big enough, Jimmy? Test it out," referencing a joke from the Wednesday show.

2015 Ford Mustang spied on video for the first time

Not many cars will continue to hold our rapt attention quite like the upcoming redesigned 2015 Ford Mustang, codenamed S550 internally. Earlier this month, we brought you the first spy photos of a next-gen Mustang prototype out testing, and even though expertly placed cladding concealed the pony car's new shape, we could tell that underneath was hiding an altogether new form inspired by the Evos Concept from 2011.
Today we give you some video of what looks to be the same Mustang prototype, which you can watch below, and while the budding director behind the camera wasn't able to capture much in the way of the engine's audio signature, we can see the car in motion for the first time and compare its relative size and shape to the S197 Mustang GT that's on its tail.

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).
