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.

Consumer Reports selling its road-tested roadsters [w/video]

Here's a chance to acquire a celebrity-owned vehicles, and this time at a discount instead of a premium. So the celebrity in this case is Consumer Reports, that magazine that could be equally adored and abhored by car enthusiasts. CR buys all of its test vehicles and usually finds willing second owners within its own ranks, but its opening its small used-car lot to the public. On the forecourt are four roadsters: an automatic 2012 Audi TT 2.0 TFSI Quattro S-Tronic with 6,600 miles for $36,500, a manual 2012 BMW Z4 sDrive28i with 8,400 miles for $45,000, a manual 2012 Mercedes-Benz SLK250 for $39,500 and a manual 2013 Porsche Boxster with 7,000 miles for $48,000.
Those numbers mean a savings of $9,000 to $10,000 before haggling - each car is listed with an "Asking price" so there could be some wiggle room if you show up with pockets full of dough and eyes full of serious intent. Since the money CR earns from the sales go back into the magazine's budget to buy more test cars, however, it probably won't take any oddball trades, so you can forget about getting any purchasing help from that track-day AMC Javelin project on blocks in the back yard.
The vehicles have been taken care of and spiffed up for sale; buyers will take delivery at the CR test track in East Haddam, Connecticut and get a tour of the facilities. While you're there they'll even take you on a lap around the track so you can feel how your car handles when driven by one of its testers. They will probably not help you with advice on which toaster and dehumidifier to buy - you'll still need to get a subscription for that. Have a look at the video below to see a day in the life of a CR test car.

2015 Mercedes C-Class owners reporting bleeding seats [UPDATE]

UPDATE: Daimler AG became aware that, in a small number of individual cases, it is possible for temporary spots and/or shiny patches to form on the man-made leather surfaces of the 2015 C-Class in sub-freezing temperatures. No accidents or injuries have been reported, and we have no reason to believe that there are any hazards to customers. Replacement parts are expected to start shipping to dealers by next week. Owners of the 2015 Mercedes-Benz C-Class are learning the hard way that you don't necessarily want to buy a new vehicle in its first model year. Besides reports of poorly fitting taillights and faulty infotainment touchpads, a number of reports are popping up on the forums of MBWorld.org claiming that the compact luxury sedan's seats are, for lack of a better term, bleeding. Owners of US-built, 2015 C-Classes fitted with MB Tex vinyl interiors are reporting a white, oily, shiny residue discoloring their seats that shows up, often after cold cars are quickly heated. It's important to note that this residue is not necessarily staining the seats permanently – warm, soapy water is often all that's needed to restore the original finish. In other cases, the residue disappears of its own accord, only to reappear in an entirely different pattern. That doesn't make things any more acceptable to owners, many of whom have reached out to Mercedes with complaints. It's not clear how many vehicles are affected, but there are a sizable number of forum threads on the issue on MBWorld alone, and the problem is prevalent enough that Mercedes has issued a technical service bulletin to its dealers. According to the forum postings, the TSB instructs service technicians to replace the headrest and seat cover (except for the front, passenger-side seat bottom because of "factory calibration issues") in affected customer vehicles. New C-Class models in dealer inventories, meanwhile, are to get the soapy water treatment if they're showing signs of the residue. Neither one of those moves seems to represent a long-term fix, though. Black MB Tex seats – both the standard and sport variety – seem to be particularly susceptible to the residue, although we stumbled across at least one image of what looks like Silk Beige MB Tex with speckles of residue.
