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-Benz introduces new heavy security M-Class Guard model

Mercedes-Benz has unveiled a new addition to the company's line of personal security vehicles. The M-Class Guard features bullet-proof side windows made with special laminated glazing and a polycarbonate inner layer to protect occupants from shards of glass. Mercedes says the M-Class Guard meets protection level VR4 according to the Bullet Resistant Vehicles 2009 standards, based on testing from the independent Ulm-based Ballistics Bureau, which means it can withstand .357 Magnum and .44 fire from multiple angles. It can also stand up to the DM51 hand grenade when equipped with optional floor armoring. Why skimp?
Buyers looking for protection from the world's literal slings and arrows can opt for the ML350 BlueTEC with its 258 horsepower 3.0-liter turbodiesel engine. With 457 pound-feet of torque, the oil-burner should have no trouble hustling the privileged class about. Of course, the ML500 offers a bit more punch courtesy of a 4.6-liter twin-turbo V8 with 408 horsepower and 442 pound-feet of torque. Prices start at 105,050 euros for the diesel and 118,650 euros for the V8. You can check out the full press release below for more information.

Gullwing America turns SLS AMG Roadster into stunning 1955 300 SC redux

Gullwing America specializes in what it calls "retro styling meets modern technology." It's next demonstration of that is the convertible above, a stylized recreation of the 1955 Mercedes-Benz 300 SC (inset) supported by the structure of a 2012 SLS AMG Roadster. Commissioned by a client in Eastern Europe, the resulting car is called the 300 SLC.
The hand-formed aluminum bodywork required just a few changes to the SLS AMG Roadster, namely reworking the headlights into a stacked arrangement of LEDs and relocating the pop-up spoiler behind the cabin. The retro grille and long, straight hood evoke the past, the custom exhaust, height-adjustable suspension, 21-inch wheels up front and 22-inch wheels in back, however, stray a little further from history. The 300 SLC will come with a hardtop and be one-of-a-kind, making it even rarer than its inspiration, of which 92 were made.
