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.

Pre-Race notes from the 2015 Nurburgring 24-Hours

Autoblog has come to the German countryside to watch the Nurburgring 24-Hour race, and just one day in, we have to say it's outstanding. Le Mans has been the highlight of our summer racing schedule for the past few years, the 'Ring 24-Hour event being the appetizer we always skipped. Earlier this year, however, while visiting Miami to check out the Cigarette Racing 50 Marauder GT S, we met Scott Preacher. He oversees digital marketing for both Cigarette and AMG during the week, then comes to Germany to compete in the VLN race series on the weekends, driving an Aston Martin Vantage GT4 for Team Mathol. If Le Mans is the Oscars of endurance racing, the Nurburgring 24-Hour race is the Screen Actors Guild award – the one voted on by the actors, for the actors. In this case it's the race by the teams and fans, for the teams and fans, even though the increasing manufacturer presence has altered the team equation. We were told that it wasn't so long ago that true privateers could win the overall, but that's not really the case anymore. Front-running teams have heavy factory involvement – Audi Sport Team Phoenix, for instance, which finished in first and third last year, has its own 'Ring race center and is running the 2016 R8; Aston Martin is represented by Aston Martin Racing and Aston Martin Test Center, and Bentley has a Bentley Motors team and uses HPT to run another team. The fan component hasn't changed, though, and you can't talk about the race for more than 60 seconds before someone brings up the battalions of spectators. Every driver we spoke to cited them as the most incredible part of this race after the track itself. It feels to us like a giant German Sebring, with thousands of people camped out in the ginormous, forested infield, many of whom have been here since Monday erecting their ornate camping compounds. There will be parties everywhere Saturday night, and so much bratwurst on the grill that the drivers can smell it when as they're blasting full speed through Wehrseifen. Even when we drove a Mercedes S63 AMG Coupe on a lap before the race, the fans waved like it was a competition. Scott Preacher's Australian co-driver Robert Thompson said, "You come around a corner and it's like you're driving full speed through the middle of a carnival." The race field itself could also be called a carnival, with an officially invited field of more than 170 cars. Even on a track that's 24.4-km long, that's like racing on the 405 at midday.

Next Mercedes-Benz GLK to get AMG variant? Not likely...

If you think Mercedes-Benz will slap an AMG badge on anything with wheels, think again. Word has it the German manufacturer will not offer buyers a performance version of the GLK, with Tobias Moers, director of AMG vehicle development, saying that he doesn't see a market for the car. That's not to say the picture won't change in the near future, however. According to CarAdvice.com, AMG is keeping a close eye on the arrival of the Porsche Macan.
"Maybe there will be a change in the market when the Porsche [Macan] comes up," Moers said, "but right now, no."
The real hitch in the giddy-up seems to be cost. Moers says developing the machine into something worthy of an AMG would represent "a huge investment." We can't exactly argue with that. Fortunately, AMG buyers have plenty of Mercedes-Benz models to choose from.
