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.

Hollywood stars drink hydrogen B-Class F-Cell emission water in Death Valley [UPDATE]

A plug-in electric vehicle can be used to power a house during a winter storm, but if you're more worried about the heat of, say, Death Valley, then maybe you'll want a Mercedes-Benz B-Class F-Cell along. That's the message of a new video from Daimler and starring Diane Kruger (Inglourious Basterds) and Joshua Jackson (Fringe) that promotes the company's hydrogen-powered car. The gist? You can drink the tailpipe emissions. The two Hollywood stars drove in Death Vally without any water in their F-Cell but had a special tank hooked up to the tailpipe to collect the H2O drips as they drove in 100+ degree temperatures. There's a reason these two actors were chosen, since they've been driving an F-Cell in their daily lives for two years, according to the Diamler press release. The text is, shall we say, a bit hyperbolic - "Their lives rely on the emissions of the B-Class F-CELL" it says, totally ignoring the film crew that is obviously along for the ride and more than likely had a few bottles with them. Also, when the California Fuel Cell Partnership promoted the same idea a few years ago, it clarified that, "A fuel cell doesn't produce enough water to fill your glass. ... If fact, fuel cells produce about the same amount of water as gasoline vehicle – about 1/3 cup for a full day of driving." Thus, this whole thing is a Hollywood stunt, but it's a visually effective one. See for yourself in the mini-movie below. UPDATE: Daimler has told AutoblogGreen that there was no "extra Hollywood magic" needed for the water collected in the video. Instead, Madeleine Herdlitschka, who works at global communications for Mercedes-Benz Cars, said, "Considering the technical characteristics, the Mercedes-Benz B-Class F-CELL emits about 9 kg of water vapor per kg of hydrogen while driving. The vehicle has a hydrogen capacity of about 3.7 kg, what is sufficient for a max. of about 400 km of range. A tailor-made construction, designed by the production company Markenfilm Crossing in cooperation with our fuel cell experts, made it possible to collect the water in a tank - previously cooling the vapor with a specially designed pipe system."

Mercedes raises the roof on new CLA Shooting Brake [UPDATE]

UPDATE: As we feared, the CLA Shooting Brake is not currently slated for US availability. The text below has been adjusted accordingly. Of all the variants in Mercedes' smallest line, only one doesn't have a liftgate, and that's the CLA-Class. But don't worry, the German automaker is out to fix that too with the reveal of the new CLA Shooting Brake you see here. Based on the same platform that underpins the CLA four-door coupe, the A-Class hatchback, B-Class minivan and GLA crossover, the new Shooting Brake applies a similar formula we've already seen on the bigger CLS Shooting Brake but in a much smaller form – which is to say, it's a wagon, but a shapely one. The revised roofline means more headroom in the back seat and significantly more cargo capacity than the four-door's trunk. Mercedes will offer the CLA with a variety of engine choices, including a 2.1-liter turbodiesel with either 136 or 177 horsepower, a 1.6-liter four with 122, 156 or 211 horsepower. That last model will even be available with 4Matic all-wheel drive for those not enamored by the idea of a front-drive Benz, but the top of the range, of course, is the CLA45 AMG Shooting Brake that carries the same 2.0-liter turbo four – all 360 horsepower of it – as the four-door CLA45 as well as the A45 and GLA45. Driving once again to all four wheels, Daimler says it'll reach 62 in 4.7 seconds (even quicker than the crossover) and top out at the usual 155 miles per hour. Of course those options only apply to markets where the new Shooting Brake will be offered. And unfortunately, Mercedes-Benz USA confirmed to Autoblog that (like the CLS wagon) the CLA Shooting Brake won't be making the transatlantic voyage to US showrooms (where the E-Class is the only low-slung Benz wagon on offer). That leaves the four-door CLA and the GLA crossover still holding down the pint-sized fort for Mercedes. THE NEW MERCEDES-BENZ CLA SHOOTING BRAKE: SPACE FOR SOMETHING NEW Stuttgart. Breathtakingly sporty proportions and a powerfully dynamic design idiom with sensuously shaped surfaces already made the CLA unmistakable in its four-door Coupe guise. It is now followed by a further design icon, the CLA Shooting Brake, with a unique look all of its own. The lower overall height and the elongated coupe-style roof contour line, the low greenhouse and the sweep of the high beltline are the key design features of its distinctive profile.
