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).

Consumer Reports no longer recommends Honda Civic

Consumer Reports annual Car Reliability Survey is out, and yes, there are some big surprises. First and foremost? The venerable publication no longer recommends the Honda Civic. In fact, aside from the walking-dead CR-Z and limited-release Clarity fuel-cell car, the Civic is the only Honda to miss out on CR's prestigious nod. At the opposite end there's a surprise as well – Toyota and Lexus remain the most reliable brands on the market, but Buick cracked the top three. That's up from seventh last year, and the first time for an American brand to stand on the Consumer Reports podium. Mazda's entire lineup earned Recommended checks as well. Consumer Reports dinged the Civic for its "infuriating" touch-screen radio, lack of driver lumbar adjustability, the limited selection of cars on dealer lots fitted with Honda's popular Sensing system, and the company's decision to offer LaneWatch instead of a full-tilt blind-spot monitoring system. Its score? A lowly 58. The Civic isn't the only surprise drop from CR's Recommended ranks. The Audi A3, Ford F-150, Subaru WRX/STI, and Volkswagen Jetta, GTI, and Passat all lost the Consumer Reports' checkmark. On the flipside, a number of popular vehicles graduated to the Recommended ranks, including the BMW X5, Chevrolet Camaro, Corvette, and Cruze, Hyundai Santa Fe, Porsche Macan, and Tesla Model S. Perhaps the biggest surprise is the hilariously recall-prone Ford Escape getting a Recommended check – considering the popularity of Ford's small crossover, this is likely a coup for the brand, as it puts the Escape on a level playing field with the Recommended Toyota RAV4, Honda CR-V, and Nissan Rogue. While Ford is probably happy to see CR promote the Escape, the list wasn't as kind for every brand. For example, of the entire Fiat Chrysler Automobiles catalog, the ancient Chrysler 300 was the only car to score a check – there wasn't a single Dodge, Fiat, Jeep, Maserati, or Ram on the list. That hurts. FCA isn't alone at the low end, either. GMC, Jaguar Land Rover, Mini, and Mitsubishi don't have a vehicle on CR's list between them, while brands like Mercedes-Benz, Volvo, Nissan, Lincoln, Infiniti, and Cadillac only have a few models each.

The most efficient gas or hybrid cars of 2024: Not the greenest, but still very green

Not a single electric vehicle appears on the “greener choices” list assembled by the American Council for an Energy-Efficient Economy (ACEEE) in its annual compilation of the most environmentally friendly cars in the United States. But for potential car buyers seeking an efficient, fairly affordable gasoline or hybrid vehicle this year, the list of 12 cars, trucks and SUVs can help with decision making. Topping this yearÂ’s list was the gas/hybrid Honda Accord, priced at $33,990 with an estimated annual fuel cost of $982. Rank Make & Model Powertrain Vehicle Class Green Score MSRP Estimated Annual Fuel Cost* 1 Honda Accord Gas Hybrid Large Car 62 $33,990 $982 2 Kia Niro FE Gas Hybrid Compact SUV 61 $28,315 $885 3 Mitsubishi Mirage Gas Compact Car 59 $17,955 $1,189 4 Lexus ES 300h Gas Hybrid Midsize Car 59 $44,590 $1,073 5 Lexus NX 350h Gas Hybrid Midsize SUV 57 $43,465 $1,207 6 Ford Maverick Gas Hybrid Compact Pickup 55 $24,900 $1,297 7 Toyota Sienna Gas Hybrid Minivan 55 $39,080 $1,304 8 Mini Cooper Convertible Gas Subcompact Car 54 $35,700 $1,412 9 Toyota Highlander Gas Hybrid Large SUV 54 $40,720 $1,348 10 Kia Soul Gas Small Wagon 53 $21,565 $1,467 11 BMW Z4 sDrive30i Gas Two-Seater 50 $53,600 $1,626 12 Mercedes-Benz GLA250 Gas Hybrid Large Van 49 $43,000 $1,596 13 Volvo V90CC B6 Gas Hybrid Midsize Wagon 45 $59,800 $1,843 14 Ford Ranger Gas Standard Pickup 43 $32,670 $1,968 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In making its evaluations, the ACEEE examines each 2024 model based on its cost to human health from air pollution associated with vehicle manufacturing and disposal, the production and distribution of fuel or electricity, and vehicle tailpipe emissions. The group also takes into account air pollution associated with EV battery manufacturing. The organization also ranks what it calls the “greenest” cars — it selected the Toyota Prius Prime SE plug-in hybrid is the greenest model of 2024. As well as the “Meanest.Â’Â’ or least efficient vehicle. At the top of that list this year was Mercedes-Benz AMG G63. The group says that the greener choices are those that are available nationwide “with among the lowest environmental impacts in each vehicle class but that didnÂ’t make the Greenest List.
