After Years Of Delays, Rear Visibility Requirements Move Closer To Reality

Regulations that would require automakers to improve rear-view visibility on all new cars and light trucks are nearing completion after six years of delays. The U.S. Department of Transportation sent its proposed rear-visibility rules to the Obama administration for review on Christmas Day. The White House Office of Management and Budget now must finalize the regulations. The rule are intended to minimize the risk of pedestrian deaths from vehicles in reverse, a type of accident that disproportionately affects children. Already in 2014, two children have died from cars backing over them, driven in each case by the children's father. Specifics of the Transportation Department's proposal are not available during the review, but the rules are expected to compel automakers to install rear-view cameras as mandatory equipment on all new vehicles. That's what safety advocates have wanted all along. Thought they were pleased the proposed ruling had finally been issued, there was some worry Friday the final rules would omit the rear-view camera mandate. "We're encouraged, but we're also a little concerned about speculation the rear-view camera may not be in there," said Janette Fennell, the president and founder of Kids and Cars, a nonprofit organization dedicated to protecting children in and around vehicles. "I'm wondering where that might be coming from." On Thursday, The Automotive News had reported the possibility the new standards could offer an alternative to rear-view cameras, such as redesigned mirrors, that improved visibility. The Office of Management and Budget typically completes its reviews of new rules in 90 days, although that can be extended. OMB officials said Friday they do not comment on pending rules. The intent of the rules is to enhance rear visibility for drivers and prevent pedestrian deaths. Approximately 200 pedestrians are backed over in the United States each year, according to estimates from the National Highway Traffic Safety Administration. Accidents Mostly Affect Children Roughly half the victims are children younger than age five. A government analysis concluded approximately half the victims -– 95 to 112 -– could be saved with new regulations. Yet the rules have arrived at a glacial pace. President George W. Bush signed legislation that had been passed with bipartisan Congressional support in 2008. But automakers have fought the idea of adding rear-view cameras, saying it is too expensive.

Our interview with Jeremy Clarkson and James May, plus SEMA! | Autoblog Podcast #491

This week, David Gluckman and Mike Austin talk SEMA madness, mis-aligned steering wheels, wireless charging, McLarens (they're sports cars!), and decals. We also have an excerpt from a recent interview with James May and Jeremy Clarkson of The Grand Tour and Top Gear fame. As always, we talk about a variety of cars we've been driving and then respond to some questions from listeners. And as a bonus, there's a trivia question mixed in. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want questionable buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com.

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).
