Vile Gossip | Adventures in tire testing

Jean Jennings has been writing about cars for more than 30 years, after stints as a taxicab driver and as a mechanic in the Chrysler Proving Grounds Impact Lab. She was a staff writer at Car and Driver magazine, the first executive editor and former president and editor-in-chief of Automobile Magazine , the founder of the blog Jean Knows Cars and former automotive correspondent for Good Morning America . She has lifetime awards from both the Motor Press Guild and the New England Motor Press Association. This is her first column for Autoblog — look for more Vile Gossip in the future. I began writing at Car and Driver magazine back in its golden age in the 1970s, before I'd actually read it. I knew very little about cars. The only magazine I read religiously was Four Wheeler because I owned big trucks and liked to go off-roading with my Chrysler Proving Grounds friends. My vast 10 years of driving experience up to that point (high-speed dirt-road idiot, taxicab driver, Chrysler Proving Grounds test driver) had less bearing on my being hired at Car and Driver than the fact that the editor just wanted to rile up the all-male staff. He didn't need me for that. They were already in full dudgeon when I arrived. They'd just spent a chunk of time testing a stack of tires for their big tire-test issue, and the editor-in-chief was toe-to-toe with the technical editor over the rankings of the top 10 tires. It was loud, and it was angry. I had no idea that car magazines tested tires. Cab driving had led me to believe that airing up a tire and changing a flat was all you needed to know. I changed so many flats on that cab, I eventually wound up in front of a live audience on the " Oprah Winfrey Show" demonstrating my brilliance with a jack and a tire iron. My point, of course, is that tires are more controversial, and also more essential, than you'd think. My other point is that it's good to get worked up about the subject, but not quite so good to let yourself be seen, as I did, on my hands and knees with my ass up in the air on national TV. This is how I prefer to test a tire: First, pick a top brand. Then accept their invitation to try and beat the crap out of their tire. I chose Yokohama, celebrating its 100th anniversary this year. The big news for them was the GEOLANDER M/T G003!

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, Volvo, Google, Uber and Lyft form self-driving alliance

Five companies arguably leading the worldwide effort to develop autonomous cars said Tuesday they're forming an organization to lobby the federal government to better prepare America's roads for self-driving technology. The founding members include some of the biggest companies in the automotive, autonomous, and ride-sharing realms – Ford, Google, Lyft, Uber and Volvo. Operating as the "Self-Driving Coalition for Safer Streets," they aim to work with lawmakers and regulators to clarify a disparate set of rules and regulations at both the state and federal levels that could hinder the deployment of autonomous cars. "The U.S. risks losing its leading position due to the lack of federal guidelines for the testing and certification of autonomous vehicles." – Hakan Samuelsson David Strickland, a former administrator of the National Highway Traffic Safety Administration who issued the first set of autonomous-related policies in that role (pictured below), will serve as the group's counsel and spokesperson. "The best path for this innovation is to have one clear set of federal standards, and the Coalition will work with policymakers to find the right solutions that will facilitate the deployment of self-driving vehicles," he said in a written statement. In January, Transportation Secretary Anthony Foxx said his department would accelerate efforts to craft such federal standards. Those efforts include holding two public hearings on standards, the second of which is scheduled to be held Wednesday in Palo Alto, California. Foxx signaled the intent to deliver them by June. Google has been leading the efforts to ensure such standards are national in scope, warning their cars could run afoul of state-specific laws should they cross state borders or if standards varies between the federal efforts and regional ones. The complexity of such efforts was underscored recently, when NHTSA agreed that Google's software could be considered the driver of a vehicle for the purpose of meeting federal motor vehicle standards, an interpretation that would conflict with preliminary California rules that mandate a licensed driver operate a self-driving car that comes equipped with human controls like a steering wheel and brakes. At South By Southwest last month, Jennifer Haroon, Google's self-driving car business leader, said the company couldn't accomplish its goals under those regulations.
