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).

Muscle wins big at 2013 Amelia Island Concours as 1936 Duesenberg, 1968 Ford GT40 take top honors

The 18th-annual Amelia Island Concours d'Elegance took place this past weekend, and in one of the show's biggest years yet (bringing in more than 25,000 spectators and attracting more than 300 vehicles), two powerhouses ended up winning the judges' hearts. The top Concours d'Elegance award went to a 1936 Duesenberg SJN, while the Concours de Sport went to one of the celebrated marques, a 1968 Ford GT40.
Owned by Helen and Jack Nethercutt of Sylmar, CA, this flawless Duesy is described as "one of the most powerful open cars of the 1930s," and it displays design cues of the era like rolled fenders and a tapered rear end. The SJN's supercharged straight-eight allowed it to accelerate to 100 miles per hour in just 17 seconds - surely not a disappointing feat for its day.
On a much different level of performance and timelessness, this Gulf-livery GT40 from the Rocky Mountain Auto Collection is not outdone by the elegance of the big Duesenberg thanks to some well-documented racing history. This not only includes winning at LeMans in both 1968 and 1969 - Chassis No. 1075 also managed to win a total of six times in just 11 races.

2017 Ford Super Duty trucks recalled because the fuel tank could fall off

Bad news from Dearborn. Ford just announced a pair of recalls, including a particularly worrying flaw in the new F-Series Super Duty. According to Ford's official announcement, there are roughly 8,000 of its big trucks on the roads with a missing reinforcement bracket – if it's not there, the fuel tank could separate from the frame. Yes, Ford is basically saying the fuel tank could fall out. We don't need to explain why this would be a very bad thing. Fortunately, no owners have experienced said bad things – Ford claims it's unaware of any fires, injuries, or accidents resulting from the flaws. The Kentucky Truck Plant built the affected pickups between August 10 and September 17. The bulk of the vehicles are in the US – 7,103, to be precise. Another 964 are cruising around the frozen Canadian tundra, while two more are in "federalized territories." The other recall is smaller, but reaches across a broad swath of the Blue Oval's family vehicles. Ford says there are 1,352 Taurus sedans, Flex crossovers, Explorer SUVs – including the Police Interceptor Utility variant – and Lincoln MKTs equipped with the company's 3.5-liter EcoBoost V6 that could catch fire. In this case, the danger isn't a detached fuel tank, but an "improperly brazed turbocharger oil supply tube" that could leak and spill engine oil on the turbocharger. Again, Ford isn't aware of any fires, accidents, or injuries due to the flaw. Here's the breakdown of manufacturer dates and location: 2016 Ford Taurus vehicles built at Chicago Assembly Plant, Oct. 18, 2016 to Nov. 2, 2016 2016-17 Ford Flex vehicles built at Oakville Assembly Plant, Oct. 18, 2016 to Nov. 10, 2016 2017 Ford Explorer vehicles built at Chicago Assembly Plant, Oct. 15, 2016 to Nov. 12, 2016 2017 Ford Police Interceptor Utility vehicles built at Chicago Assembly Plant on Nov. 2, 2016 2016-17 Lincoln MKT vehicles built at Oakville Assembly Plant, Oct. 18, 2016 to Nov. 10, 2016 As with the Super Duty recall, most of the affected cars, crossovers, and SUVs are in the US market. There are 126 units in Canada and six in the same "federalized territories" mentioned above. In the case of both recalls, dealers will inspect the affected parts and replace or add them as necessary.
