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.

Mercedes-Maybach Pullman is the luxury car for the discerning dictator

For decades, Mercedes-Benz and Mercedes-Maybach cars have been the ride of choice for leaders across the globe, presidents, ambassadors, dictators and despots alike. The Pullman model — a long-wheelbase six-seat variant — has been particularly popular with this select clientele. This week, the German automaker announced the latest version of the car, the Mercedes-Maybach Pullman S650. Essentially, this is a stretched version of the V12-powered Maybach with two rear-facing seats just behind the front row. Mercedes is calling this vis-a-vis seating. There's also a partitioning glass between the front seats and the rear cabin. This is of course to help prevent the chauffeur from learning and spilling any state secrets or plans for plans for secret moon bases. New for this model is a front-facing camera for rear-seat passengers. This allows occupants to watch for any oncoming obstacles, barricades or road blocks. Visually, there's no mistaking the Pullman for another Maybach or really anything else on the road. The car is 21.3-feet long, 4.5-feet longer than the standard Maybach or roughly the size of two and a half Smart Fortwo placed bumper-to-bumper. The requisite 20-inch 10-hole wheels are present and the standard pinstripe Maybach grille has been updated with a slightly new design. The car only comes in S650 trim, meaning it's powered by a 630 horsepower 6.0-liter twin-turbo V12. As expected, the Mercedes-Maybach Pullman isn't cheap. Orders have started, but be prepared to shell out at least $615,000 before adding any custom touches.
