Ford Mustang GT500 successor spied near SVT

Details about the next-gen Ford Mustang are scarce, and there's even less information out there about the upcoming replacement for the Shelby GT500. Previously rumored to drop the Shelby name and wear the GT350 moniker, the highest-performance Mustang has just been spotted testing near Ford's SVT operations.
Despite being cloaked in heavy camouflage, we can instantly tell this prototype is different from other Mustang spy shots we've seen in the past. Aside from the Shelby-spec wheels, quad exhaust outlets (previous spy shots show only two) and beefier brakes, this car also has air intakes on the hood and front fenders. These elements help to neither prove nor dismiss rumors that the next SVT Mustang will be naturally aspirated. It also looks like Ford is may be planning some changes to this car's rear suspension, as there is some extra camouflage added beneath the rear end of this prototype.
As a bonus, these spy shots also give us our first look inside the new Mustang, revealing a new steering wheel (with more buttons) and a glimpse of the dual-pod instrument gauges. Check out past spy shots of the 2015 Mustang showing off its new face and driving around town.

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).

How Ford made its 2015 Ford Mustang safer for toupee wearers [w/video]

Ford is ready to tell the story of its 2015 Mustang Convertible, the can't-miss bits being the easier, quicker and quieter roof operation, a more robust roof build for a coupe-like cabin noise, more trunk space, better visibility and reduced in-cabin buffeting. The top release system has been completely redesigned with a single, center-mounted latch on the windshield frame instead of the dual latches of before. The driver can now release the roof without having to lean over into the passenger space, after which the top goes down fully automatically with the press of a button. Ford doesn't say how long it takes to stow, but it's apparently done in half as much time as before, so figure around 8 seconds.
The roof uses a five-bow structure, with the fabric outer and full inner headliner sandwiching ten millimeters of insulation. Detailing work on the top has eliminated "unsightly folds" in the corners when the roof is up and made it more compact when down; its Z-fold assembly is 6.7 inches lower than before at its highest point when put down. Ford says the new electric drive internals make less noise when in operation, and the fully-finished droptop look is achieved with snap-in caps that flank the rear seating and stow in the trunk when not in use (the outgoing Mustang's top was higher and the front when folded and always looked like it was catching air and creating drag).
The compact roof and newly independent rear suspension setup in back means liberated trunk space, 11.4 cubic feet ready to swallow golf bags and tourist swag. You can read a lot more about it in the press release below, check it out in the short video of running footage and learn about the aerodynamic improvements made to the entire Mustang lineup that decrease drag and increase fuel economy.
