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-AMG considering turbo fours, hybrid sixes for future performance sedans

Think of the letters AMG and you'll probably end up picturing a performance sedan with a big V8. Such has become, after all, the Mercedes turning division's calling card. But with the introduction of its 2.0-liter turbo four, AMG is working at turning that notion on its head.
The highly potent engine produces 355 horsepower and is presently installed in the A45 AMG hatchback, CLA45 AMG sedan and GLA45 AMG crossover, giving Benz's smallest family a full range of performance models. But that might not be the full extent of the high-strung four-pot's use.
Speaking with AMG boss Tobias Moers, Britain's What Car? magazine reports that Affalterbach is considering slotting the same engine into larger models, particularly performance sedans like the C-Class. As we recently reported, Mercedes is already preparing to up the power from the turbo V6 in the C400 to slot a C450 Sport in below the C63 AMG. The C450 is expected to offer around 367 horsepower where the CLA45 AMG et al pack 355, but the lighter weight of the four-cylinder engine would likely offset the truancy of those extra dozen horses. Of course such a prospect would be much further down the pipeline than the C450 Sport which is expected to arrive much sooner.

Mercedes previews new C63 DTM racer alongside Edition 1

The new C-Class Coupe will undoubtedly be one of the main points of focus at the Mercedes-Benz pavilion in Frankfurt this year. But the Silver Star automaker will have more than just the base version to showcase. There's be the new AMG C63, and now two additional versions. First up is the Edition 1, the designation Mercedes often applies (in some markets anyway) to launch versions of exciting new models. For the C63 Coupe, the Edition 1 features a raft of upgrades, available in either standard (476 horsepower) or S (510 hp) states of tune. It's done up in one of two exterior appearance packages, in matte gray with either yellow trim or black. The Edition 1 also wears special 19-inch wheels in the front and 20-inchers at the back, ceramic brakes, enhanced aerodynamics package, more chrome and gloss-black trim, and an optimized interior with racing buckets. Alongside the Edition 1, Mercedes will also reveal the new DTM racing model in Frankfurt. And following the teaser sketch released the other day, it's giving us our first proper look at the new touring car right here. The new C63 DTM will replace the existing C-Coupe DTM (as it has been formally styled) that has represented the automaker in its local tin-top racing series since 2012 – winning seven races over the past four seasons, but not a championship yet. If looks are anything to go by, the new racing coupe could be up to the task. Special Model to Market Launch: Mercedes-AMG C 63 Coupe Edition 1: Inspired by Motorsport Affalterbach. Mercedes-AMG is bringing the C 63 Coupe Edition 1 special model to the starting line. The exclusive colour combination in designo Magno Selenite Grey with yellow film coating and black wheels with yellow painted rim flanges reflects the graphic design of the Frankfurt International Motor Show launch version of the Mercedes-AMG C 63 DTM racing coupe which will be used in the DTM next year. The special model is equipped with Performance seats and an aerodynamics package, highlighting its proximity to motorsport. The new Mercedes-AMG C 63 Coupe and C 63 S Coupe are also available as "Edition 1" special models from market launch. The extraordinary combination of exclusive design and equipment characteristics is inspired by the optical appearance of future Mercedes-AMG racing coupes which will compete in the popular DTM series in 2016. Two exterior designs address different customer wishes.
