2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.

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.

New Mercedes-Benz S-Class Coupe spied in revealing state of dress

During a product briefing earlier this year, Mercedes-Benz told us that 2013 would be the "year of the S-Class." Makes sense, too, since the flagship Mercedes is so very close to finally showing its production-ready face. But the high-tech saloon isn't the only S-Class to talk about this year - quite the contrary. Seen here in decidedly revealing camouflage, the new S-Class Coupe will be joining its four-door compadre in the not-too-distant future, as well.
When it launches, the S-Class Coupe will officially do away with the CL-Class nomenclature. This doesn't come as a huge shock. After all, when the new E-Class coupe and convertible were launched, it officially marked the end of the long-running CLK-Class designation.
Thanks to the interesting camouflage seen here, we have a very good glimpse at how the S-Class Coupe will look when all of the molding and swirly paper are peeled off. Rakish body lines pulled from the CLS-Class meet a much more dynamic front fascia. Out back, there are horizontal taillamps rather than the vertical units used on the current car, and the whole package seems very svelte. Our spy photographer even posits that this will be "the best-looking car from Mercedes-Benz in ages."
