Ford lowers MPG ratings on six vehicles

Ford has announced that it will be lowering the fuel economy ratings on a number of its 2013 and 2014 model year vehicles after an error was discovered in the company's internal testing data. The EPA has been notified.
Worryingly for Ford, the vast majority of the vehicles affected are hybrids, including the C-Max, Fusion and MKZ in both hybrid and plug-in varieties (where applicable). Also covered as part of the rerating is the entire lineup of 2014 Fiesta engines, with the exception of the ST, including the turbocharged, three-cylinder EcoBoost.
The C-Max was originally rated at 47/47/47 mpg, but dropped to 43/45/40 last year and now to 40/42/37.

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).

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."
