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.

2016 Nissan Altima gets SR model, 39 mpg, 3 press releases [w/video]

UPDATE: After taking exception with Seyth's reaction to press-release overdose, a Nissan spokesperson commented,"It gets 39 mpg. That's ******* epic." The Mazda 6, rated 40 mpg highway, is the only car among the Altima's peers to do equal or better. (See a full list of gas-powered non-hybrid cars that do 39 mpg highway or better here.) It seems that Nissan just can't stop selling its hot Altima midsizer. At least, that's what the bullet points of the press release for the new, 2016 version of the car tell me. The model has seen five consecutive years of sales growth, occasionally hitting the 30,000-per-month figures that heavies like Camry, Accord, and Fusion regularly nab. And, as we all know, a key to keeping midsize sedans fresh is the mid-cycle refresh. Here we have it. Nissan has reshaped the front and rear of the Altima to better match the look of its handsome new Maxima. That means a deep-v wrought in chrome on the front fascia, new (optional) LED headlights that look like reverse check marks, and a lower bumper that mirrors the shape above it. There are new taillights, bumper, and trunk lid for the rear of the car, too. You'll likely have to stare at the pictures pictures of the posteriors on the old and new cars for a few minutes (as we did) to pick them out, but they're there. The press release says so. Changes to the interior are subtle. We spotted a new center stack, and new cup holders next to the gearlever. Your weird friend Brian who hosts the Altima Altimatics fan forum could probably lend more detail here, but the non-enthusiast eye sees a mild rethinking of a nice interior. The excellent Zero Gravity front seats are still standard on all trims, which is probably half the reason Nissan is selling so many of these things. (How did that not make the bullet points, guys?) Change is more evident in the new-for-'16 Altima SR trim. The lighting profile is different for the model's most athletic variant, with smoked lenses, daytime running lights and revised fog lamps. More importantly, the SR gets its own suspension setup, revised dampers, stiffer front and rear stabilizers, and a more aggressive wheel/tire package. Nissan also offers drivers the ability to paddle-shift the SR's CVT transmission. The SR grade can be had with either Altima engine option. As for the motivating forces behind Altima's new nose, well, they're mostly the same.
