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 recalls Explorer and Lincoln MKC for fire hazard

The Basics: Ford will recall 5,536 examples of the 2016 Explorer and 2015-2016 Lincoln MKC. The Explorers have build dates between October 20, 2014, and January 28, 2016, at the Chicago Assembly Plant. The MKCs are from between November 25, 2013, and January 25, 2016, at the Louisville Assembly Plant. In total, there are 3,129 total affected examples of the 2015-2016 Lincoln MKC and 2,407 examples of the 2016 Ford Explorer. Of these, 1,543 are in the US and 3,993 are in Canada. The Problem: The combination of the engine block design and the block heater in these vehicles can cause the part to overheat when plugged in. Injuries/Deaths: None reported, but there are two cases of underhood fires in Canada. If you own one: Ford will begin notifying owners during the week of May 16, company spokesperson John Cangany tells Autoblog. Related Video: Ford issues safety recall for certain 2015-2016 Lincoln MKC and 2016 Ford Explorer vehicles to replace engine block heaters Ford is issuing a safety recall for approximately 5,500 2015-2016 Lincoln MKC and 2016 Ford Explorer vehicles to remove the heaters and replace them with an updated design. The engine block design, coupled with the particular block heater installed in these vehicles, causes the unit to be susceptible to overheating when the vehicle is parked and the block heater is plugged in –increasing the risk of an underhood fire. Ford is aware of two reports of underhood fires in Canada, but is not aware of any accidents or injuries related to this issue. Affected vehicles include certain 2015-2016 Lincoln MKC vehicles built at Louisville Assembly Plant, Nov. 25, 2013 through Jan. 25, 2016 and certain 2016 Ford Explorer vehicles built at Chicago Assembly Plant, Oct. 20, 2014 through Jan. 28, 2016. There are 5,536 vehicles affected by the issue, including 3,129 2015-2016 Lincoln MKC and 2,407 2016 Ford Explorer vehicles, with 1,543 of the affected vehicles in the United States and federalized territories and 3,993 in Canada. Dealers will remove and replace the engine block heater with an updated design and, if needed, replace the cord at no cost to the customer.

Pony-car sales war: Mustang vs. Camaro vs. Challenger [UPDATE]

Update: An earlier version of this story misstated the 2015 Mustang's weight when compared with previous models. Additionally, we have added comments from Chevrolet in the text. The Ford Mustang has blown past the Chevy Camaro as America's best-selling pony car, and in June, it wasn't even close. The 'Stang outsold the Camaro 11,719 to 8,611 cars. The Camaro remained ahead of the Dodge Challenger, which sold 6,845 units. Even though the Camaro did post an 11.5-percent sales improvement in June, the competition is arguably stronger than at anytime since the 1970s muscle-car era. The Mustang's sales leapt a whopping 53.6 percent, while the Challenger saw a gain of 56 percent. Several factors are weighing down Camaro sales, including its lame duck status. Chevy is launching a new generation of the Camaro this year that's more than 200 pounds lighter, offers a new turbo four-cylinder engine option, and has a nicer interior than the outgoing model. Put simply: wait a few months and you can get a better car. It's also unlikely Chevy will jack up the price much, as it's historically kept the Camaro within reach of everyday enthusiasts. While Chevy fans wait in anticipation for their new sports car, Ford and Dodge have downshifted. The new Mustang, which went on sale last year, is faster and more sophisticated than its predecessor. It also offers a 2.3-liter EcoBoost four-cylinder, which Ford has credited for the Mustang's recent uptick and makes up 36 percent of the car's sales, Ford analyst Erich Merkle said. View 17 Photos June's performance allowed the Mustang to widen its sales gap with the Camaro this year. Through the first five months, Ford sold 68,290 Mustangs, a 54.4-percent increased compared with 2014. Chevy sold 42,593 Camaros, an 8.7-percent decrease. The Challenger – long the No. 3 pony car in sales volume – has seen its sales surge 41 percent this year to 37,011 units. Spokesman Monte Doran said Chevy expected that 2015 would be a "relatively soft year" for the Camaro. "Mustang is taking advantage of years' worth of pent-up demand for an independent rear suspension," he said. "When Camaro introduced an IRS, in 2009, it helped make us the best-selling performance car in America.
