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).

Meet Shelby Mustang GT500 Miller, Iowa's latest hatchet-wielding criminal

Well, we've found the long-lost cousin of yesterday's Bentley-tattooed criminal from Florida. This is Shelby Mustang GT500 Miller. No, seriously. While his name seems just like the sort of thing we'd expect the Sunshine State to produce, he actually hails from Iowa. Despite coming from the Hawkeye State, Miller was arrested for a decidedly Floridian offense – getting in a bar fight and then returning with a hatchet. The only way this story could be more Florida is if meth, a manatee or bath salts were involved. The fight, which was at the Cheap Seats Sports Bar, started off typically enough, with a verbal argument in the parking lot (please, please let his nemesis be named "Chevrolet Camaro Z/28 Smith"). This, naturally, attracted passing police officers. Things were broken up and some friends took Miller to his home, which was apparently just behind the bar. That's when he returned with the hatchet tucked under his shirt. Miller promptly proceeded to take out the implement of destruction in the bar's bathroom and... forget about it entirely. Fortunately, the police hadn't left the area yet. Not surprisingly, Miller was arrested for a parole violation, as well as public intoxication and going armed with intent. Still, cool name, bro.

Chrysler called out over lackluster Ram Runner by racer who helped develop it

Fans of off-roading and desert blasting might recall that Chrysler offers an aftermarket conversion that can turn a Ram 1500 into a road-legal desert racer, called the Ram Runner. The kit, sold through Mopar, includes some significant suspension upgrades, body tweaks and a brawnier cat-back exhaust for the truck's 5.7-liter V8.
Considering all of this, comparisons with the almighty Ford F-150 SVT Raptor are common. Among the off-road community, that makes these two a sort of Chevrolet Camaro and Ford Mustang for people that prefer driving on dirt. In the Race-Dezert forum, the discussion as to which truck was better was proceeding as normal - Ram fans said their piece and Ford fans said theirs. Then, a man named Kent Kroeker offered up his two cents.
See, Kroeker is a Baja racer, and the man that helped develop the Ram Runner. Despite his association with the truck, though, he had some less than kind words for Chrysler and the Ram Runner.
