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).

Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.

This Ford F-150 might have a Land Rover turbodiesel V6

Our spy photographers just caught this Ford F-150 driving around Dearborn, wearing camouflage around the bed – not so unusual near Ford's headquarters. What's interesting with this particular mule is that it might be packing a Jaguar-Land Rover turbodiesel V6. As with the Super Duty, the F-150 prototype pictured here sports a Venturi exhaust tip popping out the side of the rear bumper behind the wheel, which – along with the sound reported by our shutterbug – suggests that it's burning oil up front. That could mean Ford has found another application for the 3.2-liter, five-cylinder Power Stroke diesel that it just federalized for the Transit van. However our sources suggest what the mule is actually powered by the 3.0-liter Lion V6 diesel that Jaguar Land Rover – once subsidiaries in Ford's Premier Automotive Group – is bringing over for the Td6 models of the Range Rover and Range Rover Sport. The engine produces a respectable 254 horsepower and a healthy 443 pound-feet of torque, and is tipped to be mated to the same ten-speed automatic transmission as the new Raptor. That could give the F-150 the kind of fuel economy and muscle it would need to challenge the likes of the Ram 1500 EcoDiesel and the heavier-duty Nissan Titan with the Cummins engine. With gas prices as low as they are, however, and sales of diesel-powered vehicles lagging, Ford could just be trying to keep up with the competition by offering a light-duty diesel pickup. With its lightweight aluminum body, the diesel F-150 could even surpass the Duramax diesel-powered Chevy Colorado and GMC Canyon for frugality at the pumps, according to Mark Williams of PickupTrucks.com. He told Autoblog that, "it makes perfect sense for Ford to do a diesel. It seems like everyone is pushing them to do a Ranger, but if they can get the F-150 to push 30 mpg it can challenge the Ram Ecodiesel and even the Colorado Duramax." Reached for comment, Ford spokesman Mike Levine sent us the following statement: "We do not speculate about future products. While diesel is a solution, it is not the solution. EcoBoost offers the ideal combination of performance and fuel economy that over 60 percent of F-150 customers are choosing."
