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.

Weekly Recap: Takeaways from the Frankfurt Motor Show

We obsessively covered the 2015 Frankfurt Motor Show, and naturally, we selected our favorites from this fall's biggest automotive event. Now that the dust has settled, we're looking ahead to what it all means. Here are three takeaways from the floor in Frankfurt. The Germans are serious about electric vehicles: It's a bit cliche to say BMW, Mercedes, and Audi have downplayed electrics in favor of other technologies, like diesels. For a time that may have been true, but those three companies, along with Porsche and Volkswagen, are emerging as leaders in EV development. That was on display in Frankfurt, when all of them revealed either all-electric or plug-in hybrid models. Gas prices are relatively low in the United States, but clearly the Germans are thinking long-term and globally. Everyone is serious about SUVs: You gotta have one, even if you're Bentley or Jaguar. It's 2015 and it's what consumers want. As Jaguar design director Ian Callum put it, "Not to be in the sector would be a little naive for the sake of purity." It's not just the flashy exotic luxury makers. Nissan showed the Gripz concept, which is rakish, radical, and meant to blend traits of SUVs and sports cars into a vehicle that really crosses over. Look for more, especially in the luxury sector, as Rolls-Royce, Lamborghini, and Aston Martin ramp up their own SUV efforts. There's no ceiling to the luxury market: Speaking of high-end cars, companies are continuing to invest in extravagant wares beyond just SUVs. Even during the recession, ultra-luxury makers remained relevant, and now they're back at full stride. In Frankfurt, that was illustrated by yet another S-Class model, the cabriolet, which will come in S550 and S63 AMG variants in the United States. Ferrari also showed off the 488 Spider, and Lamborghini opened up the Huracan LP 610-4 Spyder. Meanwhile, Bugatti's Vision Grand Turismo concept reminded enthusiasts that it's plotting life after the Veyron. European auto shows always draw the glitziest reveals from luxury makers, and this year didn't disappoint.

Carlsson SLK 340 Judd is winged up for hill climb glory

Carlsson has been expertly tuning Mercedes-Benz products for more than 20 years now, but we can't say as we remember the outfit turning out anything quite so racy as this SLK 340 Judd that it has brought along to the Geneva Motor Show this year.
This SLK is meant for competition, obviously, and Carlsson has already booked the car to race in several hill climb events in the E1 category. The purpose-built racer should have a fighting chance to do well in said races, with a shape vetted in wind tunnel testing for maximum downforce, the SLK uses a carbon-fiber bodyshell to help achieve a curb weight of just about 1,720 pounds.
The featherweight SLK's name comes from its 3.4-liter V8 engine, which churns out a wicked 610 horsepower to go with its 317 pound-feet of torque. A Hewland transmission with paddle shift operation manages all of the thrust.
