Meet the Greenest and Meanest vehicles of 2016

If you've been keeping track, you won't be surprised with the number one entry in this year's list of greenest cars from the American Council for an Energy-Efficient Economy (ACEEE). In fact, the top three spots on the 2016 list are all the same as they were in 2015. After that, things get interesting. For one thing, this is the first Greenest list that doesn't have any purely internal combustion engine powertrain on it. Hybrids, yes, but if you want to be one of the top 12 greenest cars this year, you'd better have some sort of electric angle. ACEEE says that the conventional, gas-powered Smart Fortwo and Chevrolet Spark just missed the cut. In a statement, ACEEE lead vehicle analyst Shruti Vaidyanathan said, "The 2016 scores are in, and plug-in electric vehicles are outpacing all other vehicle offerings in terms of environmental friendliness." Like last year, one of the noticeable vehicles missing from the green list is the Tesla Model S. One reason? ACEEE takes curb weight into account (lighter is better), and the Model S is a heavy beast. The ACEEE doesn't just look at the clean side of the ledger. It also puts out a "meanest" list. These are the vehicles that pollute the most, not only from their tailpipes, but also any pollution created during the entire manufacturing process, from mining the raw materials to the energy used to produce the vehicle at the factory. The entire list, from greenest to meanest, is done using a "cradle to grave" analysis.

Translogic 174: Ford envisions the future of parking

Translogic visits Georgia Tech for a glimpse at the future of parking. First, we demo the Ford remote parking program by driving a golf cart around campus from the comfort of an off-site lab; think of remote parking as a virtual valet. Then we see how Ford's "parking spotter" works, a crowd-sourced way of finding an open space. Along the way, Translogic host Jonathon Buckley chats with Ford's global director of vehicle electrification and infrastructure, who explains how these innovative parking concepts could help us get around more efficiently.

VIDEO TRANSCRIPT Jonathon: You turn the wheel and the cart turns the wheel because we've got to remember that the carts 150 meters down that way. I should use yards because I'm not in Australia any more. Welcome to Translogic. I'm Jonathon Buckley. Every year in this country we spend over 70 million hours looking for parking. We think that's a pretty miserable way to spend that time but Ford Motor Company and Georgia Tech have taken this problem head on by developing a parking spotter experiment and some pretty cool remote driving functions to go with it. When it comes to remote vehicle repositioning, you guys have been so far using golf carts?Mike: That's right.Jonathon: What's the goal with this type of technology?Mike: As you probably know, car sharing is becoming one of the emerging trends in mobility. With that, any type of sharing program that we looked at around the world, one of the common challenges it has is that during the end of the day, or the nighttime hours, there's something that has to happen to get all the assets back to where they need to be for the next day. Cell phone technology and broadband technologies have advanced so far that we can remotely control a vehicle from anywhere it the world. For example, we could actually take this and create a virtual valet. You and your significant other pull up to, say, a restaurant. You could potentially get out of the vehicle and then the call center could take your vehicle and park it for you. You wouldn't need to do anything [00:02:00] else other than arrive at the restaurant.Jonathon: The whole thing's pretty intuitive. It works exactly as you imagine a golf cart would work. The only difference that there really is is there's just a little bit of latency that you have to account for.

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).
