Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Angry Nissan Leaf Driver may make 'Rolling Coal' illegal in New Jersey

It's always a few bad apples who ruin polluting just for fun for the rest of us. That time-honored American tradition of being rude for laughs, otherwise known as 'rolling coal,' might become illegal in New Jersey, if a Nissan Leaf-driving politician gets his way. The politician in question is State Assemblyman Tim Eustace (D-Bergen), who was purposefully hit by a blast of dark smoke recently while driving his Leaf on the New Jersey Turnpike, according to NJ.com. This personal experience of what he called "just youthful ignorance" is encouraging him to submit a bill (A3583), which, "Prohibits retrofitting diesel-powered vehicles to increase particulate emissions for the purpose of 'coal rolling'; prohibits the practice of 'coal rolling.'" If you're caught violating the law, you would be hit with a fine from the state Department of Environmental Protection. Of course, the Feds say it is already illegal to modify an exhaust system in a way that allows coal rolling. Rolling coal has become a bit of a meme recently, with videos of laughing truck drivers spewing their modified exhaust pipes at green cars, pedestrians and bikers around the country. Eustace told NJ.com that, "People had been telling this has been going on, but I hadn't seen it. I was surprised to experience it myself." Perhaps a coal roller in New Jersey will be surprised, too, when the first big fine hits. News Source: NJ.comImage Credit: YouTube Green Nissan Green Culture Diesel Vehicles rolling coal
