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).

Jeremy Clarkson chooses his top 10 cars for 2015 and 2016

Jeremy Clarkson is well-known for his role as co-host on the old Top Gear. But the frontman of the upcoming Amazon Prime Show, The Grand Tour, also has a standing column for The Sunday Times in the UK where he reviews the latest cars. With fall nearing, Clarkson put out a list of his top-10 cars from this year and 2015. Some on the list will surprise you, while others represent everything we've come to love about Clarkson. In order to make his list of star cars, the vehicles must offer what co-host James May calls "the fizz." The vehicles, Clarkson claims, have something that is out of the ordinary. Whether it's the car's looks, the way it gets up to speed, or its high-tech gadgets, Clarkson's top-10 list is made up of items that are more than just tools for getting from point A to B. So which ones made the list? Head over to the column in The Sunday Times.

2016 Ford F-150 gets propane, CNG conversions

It's a complete mystery if a hybrid Ford F-150 will ever see showrooms, but for buyers looking for an alternative fueling method, Ford has an option ready. For the 2016 model year, the Blue Oval is offering a kit that converts the pickup's 5.0-liter V8 to run on compressed natural gas or propane. The package costs $315 and adds improved valves and valve seats to work with the gaseous fuels. From there, the F-150s go to an upfitter to install the actual fuel tanks, lines, and injectors. Ford estimates this costs $7,500 to $9,500, depending on how much CNG a buyer wants to carry. After the conversion, the tow rating remains the same as running on gasoline, and payload is only reduced by the weight of the system. Ford offered a CNG option on the last-gen F-150's 3.7-liter V6, and sales beat the automaker's forecasts. With the greater grunt available from the V8, the company is expecting the conversion to be even more popular on the new pickups. In times of high fuel prices, CNG models have been a way for fleets to reduce their costs. According to Ford, the average price of natural gas nationwide is $2.11, but it's as low as $1 in some areas. The US Energy Information Administration lists the average for regular gas at $2.57 and diesel at $2.81. Chevrolet and GMC also offer a CNG conversion option on some of their heavy-duty trucks, and Ram does, as well. 2016 F-150 WITH CLASS-EXCLUSIVE COMPRESSED NATURAL GAS, PROPANE CAPABILITY GROWS FORD'S ALTERNATIVE FUEL LEADERSHIP Responding to customer requests, 2016 Ford F-150 with the 5.0-liter V8 engine will offer a gaseous-fuel prep option, making it the only light-duty pickup capable of running on compressed natural gas or propane Ford has sold more than 57,000 vehicles prepped to run on clean, low-cost compressed natural gas and propane – seven times more than all other major U.S. automakers combined – since 2009 Ford has the broadest portfolio of natural gas and propane offerings, including 2016 F-150 and Super Duty trucks, and Transit and Transit Connect vans and wagons Ford Qualified Vehicle Modifiers offer a wide variety of CNG options to help customers find the best, most cost-effective solution to their diverse operating needs Ford, America's truck leader, will offer the 2016 F-150 with an available gaseous-fuel prep package that enables 5.0-liter V8-powered models to run on clean, low-cost compressed natural gas or propane, making Ford the only manufacturer of a CNG/propane-capable half-ton pickup.
