Ford pits Cobra Jet versus GRC Fiesta ST, worlds collide

Racing takes on many forms in the automotive world. There are sanctioned events that are as varied and diverse as NASCAR, Formula One, Global Rallycross and drag racing, and to be good enough to win competitively in one discipline, you need to have a specialized vehicle. Or do you?
Ford decided to find out what would happen when its Global Rallycross Fiesta ST, driven by Tanner Foust, lined up against its Mustang Cobra Jet drag racer, driven by Roy Hill. In one lane, Tanner has just 2.0 liters of displacement to work with, while Roy has more than double that, at 5.0 liters. Evening the playing field a bit, Tanner has a massive turbocharger and all-wheel drive; Roy has to filter all his supercharged power through the rear wheels only.
So, who wins? We suggest you see for yourself in the press release and video below. And we're holding out hope that Tanner's challenge at the end results in another video from Ford Racing...

2015 Ford Mustang leaked in Autoweek

We would have to imagine that Ford knew it couldn't keep its 2015 Mustang under wraps for too long, and with only days to go before the pony car's official unveiling, the dam seems to be cracking. SVTPerformance.com member Screamin 40th just posted some images taken of the sixth-gen Mustang prominently featured in and on the cover of the December 9 issue of Autoweek magazine.
These images show that recent renderings we saw weren't too far off. The face is just like what we saw in spy shots a few months back, but the rear of the car features some of its more striking cues. Starting with the pronounced haunches and hidden B-pillars, the rear view of the new Mustang might be its best with the ridged, three-bar taillights, a rear diffuser and the lack of a faux gas cap, which allows the galloping pony to be an even more prominent element against the black trim.
The images also reveal a small portion of the updated interior carrying over retro themes like the deep-dish steering wheel and dual-gauge instrument cluster, but it also adds some modern tech with a big infotainment displays and a clean center stack layout. No official word on powertrain or other specs, but while we can't make out most of the magazine's text, our eyes did catch mentions of an independent rear suspension and a 200-pound weight reduction.

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).
