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.

F1's Sebastian Vettel, Lewis Hamilton face off again in Austria

SPIELBERG, Austria - Sebastian Vettel celebrated his 30th birthday on Monday, but it can be safely assumed that Lewis Hamilton will not be bringing any gifts to Austria this weekend. After the "road rage" of Azerbaijan two weeks ago, the Formula One title rivals head to the bucolic surroundings of the scenic Red Bull Ring and its backdrop of hills and forests, with controversy still simmering. Vettel, Ferrari's championship leader, had risked a heavy penalty for his moment of madness in driving into Hamilton's Mercedes behind the safety car in Baku but instead the German arrives in Austria with no further sanction and the matter officially closed. Vettel has had to accept full responsibility, and apologize to Hamilton, and will have to stay on best behavior with a race ban looming if he collects any more penalty points on his license this weekend. The FIA said Monday's meeting was attended by top officials including race director Charlie Whiting and safety director Laurent Mekies. "Following detailed discussion and further examination of video and data evidence related to the incident, Sebastian Vettel admitted full responsibility," the FIA said. "In the heat of the action I then overreacted, and therefore I want to apologize to Lewis directly, as well as to all the people who were watching the race. I realize that I was not setting a good example." A formal apology was published on Vettel's personal website. "During the re-start lap, I got surprised by Lewis and ran into the back of his car. With hindsight, I don't believe he had any bad intentions," he said. "In the heat of the action I then overreacted, and therefore I want to apologize to Lewis directly, as well as to all the people who were watching the race. I realize that I was not setting a good example. "I love this sport and I am determined to represent it in a way that can be an example for future generations." But the incident, the sport's major talking point post-Baku, is unlikely to die down immediately even if Mercedes say they have moved on. Hamilton, for one, has said nothing. But he has kept social media buzzing with news he had "liked" a fan's supportive post on Instagram that said the Paris decision had sent the message that "you can do whatever you want on track, smash into each other but if you suck up and just apologize and you get away with it." Hamilton is now 14 points behind Vettel after eight of 20 races, with a loose headrest costing the Briton victory in Azerbaijan.

Mercedes Concept IAA shows its mighty morphing aero aids

Modern supercars are utilizing more active aerodynamic elements that constantly adjust, to make them some of the fastest things on the road. The Mercedes-Benz Concept Intelligent Aerodynamic Automobile is using them too, but the know-how is applied here for ultimate efficiency rather than turning better lap times. In the standard design mode, the four-door luxury coupe looks like a CLS from the near future with styling that's mixed with a little of the F 015 concept. However at the press of a button or upon hitting about 50 miles per hour, the IAA transforms into aero mode to have an insanely low drag coefficent of just 0.19. To achieve the ultra-efficient shape, the rear of the concept stretches over 15 inches to guide air down the tail. Flaps in the bumpers also extend outward, and the wheels adjust to improve the flow around the sides. To trim things out underneath, a portion inside the front bumper moves, as well. Inside, passengers sit in organically shaped leather seats, but occupants have to look at a vast array of purple and blue LED accent lights. The big panoramic roof is a nice touch, though. It would be interesting to watch water tumble over this slippery shape when driving in the rain. To maximize efficiency, Mercedes powers the IAA with a plug-in hybrid that's hooked up to a gasoline engine. The result is 275 horsepower and an electronically limited top speed of 155 miles per hour. On the European testing cycle, the company figures the concept could cover 41 miles solely on electric power in aero mode. Showing the gains of the swoopy transformation, that figure falls to 38.5 miles in design mode.
