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 may be working on a new electric car dubbed 'Ecoluxe'

Automobile has a lengthy piece this month on how the four German mass-market luxury manufacturers each plan to go after Tesla with their own electric vehicles. It was written by Georg Kacher, the magazine's European bureau chief, and the English version came a month after he wrote the German-language original for Autobild. Tesla isn't exactly a threat to the Germans, but, according to the report, the Model S is planting the right kinds of seeds in niches that are important to the luxury players. The thinking is that - in addition to needed electric vehicles anyway for stricter US regulations - it's better to start designing the machinery now. The article posited Porsche's attack would rest on the coming Panamera platform, but a big hurdle would be battery placement. Unable to find one large space for a lithium-ion pack, engineers would instead put batteries everywhere they could, for a supposed tally of some "108 battery pouches" throughout the body. A few days after the Automobile piece, however, Porsche publicly said it had no intention of challenging the Model S, because the enthusiastic driving the brand is known for doesn't jive with useful range. In Kacher's retelling, Mercedes' plans are even more ambitious, supposedly taking aim at the Model S and the coming Model X. It would do this with an investment in excess of $2 billion in a program called "Ecoluxe" – Mercedes has no brand division akin to BMW's i and Audi's e-tron. The new brand would create a four-strong family of bespoke electric vehicles: a smaller platform with a wheelbase around 106 inches and a larger one with a wheelbase around 118 inches. In addition, the range would have "provisions for rear-wheel drive, all-wheel drive, and rear-wheel steering." The numbers are impressive: seating for seven in the larger vehicles, both longer than 16 feet, front and rear storage areas, ratings of up to 610 horsepower and production capacity of 80,000 units per year. When would we see such creatures? Perhaps as soon as 2019. We do know that if Tesla can knock the Model X over the outfield fence, automakers are going to have to do something. We don't know what the chances are that Ecoluxe is Mercedes' first move - but such a plan could help explain the weird Mercedes concept spied in October.

Mercedes-Benz C-Class 'bleeding seat' problem resurfaces [UPDATE]

UPDATE: We received the following statement from Mercedes-Benz: "In rare instances, we incorrectly ordered some of the replacement parts for the seating surfaces. The approved replacement parts will not demonstrate the previous symptoms." It appears Mercedes-Benz has another problem with "bleeding seats" in 2015 C-Class sedans. As we reported in January, an oily residue has been appearing on some versions of the C-Class with man-made MB Tex upholstery, making it look as though the seats were grimy or "bleeding." Mercedes issued a technical service bulletin to its dealers to remedy the problem, but now we're hearing the fix isn't complete. Small parts of the seats – the rear bolsters and a piece below the center armrest – weren't replaced during service and then developed the oily reside again, a source tells us. This occurred within a few days of their service appointment. The dealer followed Mercedes' instructions, our source said, and their C-Class appears to have been one of the first cars fixed. "I'm absolutely flabbergasted at this point ... The new C-Class is such a good car. This is just a shame," they told Autoblog. The bleeding seat issue appears to affect US-built C-Class models with the MB Tex vinyl and possibly other interiors. The bleeding often occurs when a car has been sitting in the cold and then heats up quickly. The number of cars affected is unclear, though the C-Class owners have been vocal in the MBWorld.org forum. At the time of our original report, Daimler AG, parent of Mercedes-Benz USA, said it was aware of the issue and that no injuries had been reported. The residue usually washes off with soap and water. The National Highway Traffic Safety Administration had no recalls, complaints or investigations recorded about the issue as of Wednesday. The fix at the dealer involves changing out the headrest and seat covers, except for a part of the passenger seat that needs to be calibrated by the factory, according to the bulletin. The C-Class is a critical car for Mercedes as it battles BMW, Lexus and others for supremacy in the ultra-competitive luxury segment. The C-Class, which launched last fall, is moving upmarket as Mercedes reshuffles its lineup with the addition of the CLA sedan. The C-Class was the company's best-selling model in January with volume of 6,236 units.
