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 working on new inline-six engines

Mercedes-Benz will make a return to the inline-six-cylinder engine game, according to a report from the UK's AutoCar. It's not clear what's prompting the phasing out of the current array of V6s.
We'll see the first inline-six from Mercedes in next-generation E-Class, set to debut in 2016. Following that, it'll arrive as part of a mid-cycle refresh for the C-Class in 2017. What's particularly special about the new inline-six is its modular nature, which will allow Mercedes to eventually spinoff three- and four-cylinder options, with the three-pot arriving alongside the new inline-six.
In other news, AutoCar uncovered some details on the next C-Class AMG, which will ditch its excellent 6.2-liter, AMG V8 in favor of a 4.0-liter, twin-turbocharged V8, although we've already told you about that. What we didn't know at the time, though, was that the 4.0-liter would be paired first with a new, seven-speed AMG Speedshift transmission and offer all-wheel drive. AC also reports that a nine-speed Speedshift is in the works.

Mercedes-Maybach G650 Landaulet is the ultimate safari machine

Update: A Mercedes representative has informed us that the Mercedes-Maybach G650 Landaulet will not be available in the United States. The text has been updated to reflect this. Vehicles such as the Mercedes-Benz G63 AMG 6x6 and G500 4x42 are all well and good, but they have one key issue: They simply aren't extravagant enough. Now we know that sounds insane because one of those vehicles has six driven wheels and the other is available in tennis-ball green. But they must not be decadent enough because Mercedes went a step further with the new Mercedes-Maybach G650 Landaulet. While the most obvious change here is the soft-top, which will make this perfect for the wealthy to view wildlife on private safaris, we should start under the hood. The previous two monster G-Wagens made do with lowly V8s. This one features a twin-turbocharged V12 making 630 horsepower and 738 lb-ft of torque. Like its predecessors, this G650 uses a four-wheel-drive system with front, center, and rear differential locks, and sends power to solid portal axles front and rear. These axles move the differential and drive axles above the wheel centers for additional ground clearance. Inside, the rear passengers will be in the lap of luxury, even while the driver is navigating particularly harsh terrain. The soft top can be electrically raised or lowered, as can a glass partition to the driver's compartment. The two individual rear seats can be fully reclined, and leg rests deploy from below, taking full advantage of the truck's long wheelbase. This would likely make for an amazing vehicle for stargazing. The passengers also have access to folding tables, 10-inch LCD displays, and heated, cooled, and illuminated cup holders. Only 99 of these G650s will be built. Mercedes will show the SUV at this year's Geneva show, and it will hit the market this fall. Mercedes hasn't announced pricing, but expect it to be exorbitant. Not that matters for American buyers, since a Mercedes representative told us it won't be offered in the States. For buyers in countries where the G650 will be available, they will have the option of four interior color schemes, three soft-top colors, and four paint hues. Related Video:
