These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

GM marks 500 million vehicles

General Motors is marking a major global milestone, as 500 million vehicles have rolled off its assembly lines since the company's founding in 1908. To mark the occasion, the automaker is continuing to invest in production and offering a one-time discount to some customers. GM North America boss Alan Batey used the festivities to announce the Fairfax Assembly factory in Kansas as one of the sites earmarked for the company's $5.4 billion in upcoming investments. The plant will get $174 million of that money for new equipment and technology to build the 2016 Chevrolet Malibu. Among the upgrades will be a shake-and-rattle booth that will simulate road conditions to find squeaks. To commemorate both the production milestone and the Fairfax plant, Batey and company CEO Mary Barra also gave away a 2016 Malibu to a wounded Iraqi war veteran, and the two execs announced that in the third week in May all GM employees can share a one-time customer appreciation discount with friends to help get them into the automaker's products. Barra also gave a speech to the workers there about some of the other milestone's in the company's history, which you can read below. Innovation on the Line: GM Manufacturing Milestones Many of General Motors' most important innovations have occurred behind the scenes, in its manufacturing facilities. Concepts such as changeover, flexible assembly, automation, computer simulation, machine vision and robotics were developed at GM. Over the decades these innovations have helped enable improvements in vehicle quality, efficiency and competitiveness. 1901: Ransom Olds' famous Curved Dash Oldsmobile, designed with simplicity, reliability and value in mind, was the first American car built in a factory designed specifically for automobiles and in standardized volume production. GM acquired Oldsmobile in 1908. 1908: Cadillac wins the Dewar Trophy, Europe's most prestigious award for precision and excellence in manufacturing, by demonstrating the auto industry's highest standards for precision and interchangeability of parts by disassembling three Cadillacs and mixing the parts randomly before reassembling and driving them before a contingent of judges. 1922: GM hires William Knudsen to lead Chevrolet's turnaround. Knudsen implements flexible mass production, which helps Chevrolet incorporate annual styling changes and take market share from Ford.
