2015 Ford Mustang: Obsessively covered [w/videos + poll]

Here at Autoblog, we've officially stamped December 5, 2013, as Ford Mustang Day. Sure, the sixth-generation Pony Car started leaking out onto the web days ago, but all of the official, non-embargoed hotness has come out today. And man, there's been a lot.
In terms of new car debuts, this is a really big one - not unlike all of the Corvette madness that kicked off the 2013 automotive season. So to make sure you haven't missed anything, here's a wrap-up of everything you need to know about the 2015 Ford Mustang.
Deep Dive: 2015 Ford Mustang

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).

Ford GT40 makes historic return to racing at Goodwood

Is there a more iconic, American racecar than the Ford GT40? That may be a discussion for another day (although by all means, tell us how wrong we are in Comments), but this video of heaps of GT40s running in the Goodwood Revival races certainly has us thinking that Ford's Ferrari-killer might just be the best racer the Land Of The Free and Home Of The Brave has ever come up with.
That's completely ignoring the fact that the GT40 was largely developed by Brits using American money, but that's besides the point (there was also a rather brash Texan, who had a big role later in development). The resulting vehicle was dominant, besting the cars of Il Commendatore from 1966 to 1969, although it should be noted that Ford's GT40 was unable to beat Ferrari in its first two Le Mans outings in 1964 and 1965.
Those four years of dominance, which started with Ford sweeping the podium, were enough to establish the GT40's legend. And now, here we are almost 50 years later, celebrating the mid-engined monsters at Goodwood, in their first ever one-make race. Take a look below for the entire video.
