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 A45 AMG in downhill battle with slipstream skateboarder

We're told it takes "performance, control and expression" to pilot a longboard skateboard down a mountain road, and that those happen to be the same values embodied in the Mercedes-Benz A45 AMG. That's how the two came to be combined in a black-and-white short film called Silver Slipstream.
There's no talking, no engine note and no color, just some music, a 'boarder and a car on a long cruise down the Franschhoek Pass in the Western Cape of South Africa." Despite that, it's actually a pretty entertaining video of the latest Mercedes-Benz hot hatch married with extreme sports. You can watch how it all goes down in the video below.

2014 Mercedes-Benz SLS AMG Black Series [w/video]

Now Even Sharper Than The Razor's Edge
There have been five Black Series models since the Mercedes-Benz SLK55 AMG Black Series introduced itself to European audiences in 2006. Following that, the Black Series club has hosted appearances by the 2008 CLK63 AMG Black Series, the 2009 SL65 AMG Black Series and last year's 2013 C63 AMG Black Series. The sixth member of the group is one we would have thought already was a Black Series car in its standard guise. Right out of the box, the SLS AMG is loud, frenetic, cozy, boisterous and frightfully easy to oversteer. How much more Black did it need to get?
Quite a bit so, apparently. The SLS AMG Black Series has lost weight, gained power and been refitted with upgrades and aero bits from front to rear. If you liked the way it looked before, you'll probably be an even bigger fan of this one. If you thought it looked ungainly, well, this one should stay even further away from pageants. Regardless of where you come down this is the best SLS AMG variant we've driven.
