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.

Petrolicious shows Mercedes 280SL as architecture in motion

While still an absolute beauty today, the design of the pagoda-roof W113 Mercedes-Benz SL was revolutionary when it debuted. Moving away from the soft curves of the previous SL models, the all-new generation brought an upright, angular shape that was as much architectural as automotive. In the latest video from Petrolicious, owner and architect Daniel Monti expounds on the inspiration that he gets from his 1969 280SL's fantastic styling. The roof is the most famous design feature of this generation of SL. Look at the top from the front or back, and you can see a gentle, downward arc that evokes the look of a pagoda. That one styling element is also a fabulous counterpoint to a vehicle that is largely more angular than curvaceous. Petrolicious wonderfully illustrates how some of the SL's form-follows-function design aesthetic can be found in the architect's work in this video's heaping helping of mid-century modern goodness.

Frankfurt Motor Show Notes: Why Jaguar decided to build an SUV

It was inevitable. Jaguar had to make an SUV, and that notion became reality this week with the debut of the F-Pace, an all-wheel-drive five-seater that will launch in the United States next spring. Some purists may cringe. But in an era when Porsche, Bentley, Lamborghini, Rolls-Royce, Aston Martin, and other traditional luxury brands are all building or (planning to build) SUVs, Jaguar had to evolve. While it seems like a leap for Jaguar to make an SUV, longtime design director Ian Callum said it's been in the works for years. "The first time I was asked the question was when I arrived 16 years ago," he said. So in 1999 (and probably well before that), Jaguar was already thinking SUV. What took so long? "It wasn't a priority," Callum said. Jaguar was concentrating on fixing its existing lineup, which was pockmarked with holes and poorly selling products, like the X-Type. Along the way, Jaguar and sister brand Land Rover were sold by Ford to Indian conglomerate Tata Motors. Flash forward several years, and Jaguar and Land Rover are both experiencing a resurgence in the United States and around the world. Jaguar's lineup is flush with the E-Type's modern successor, the F-Type, plus a new version of the XF. The XJ received a 2016 freshening, and the smaller XE sedan is on the way. Jaguar put its house in order as other factors conspired to make a crossover timely. Fuel prices stayed relatively low, and consumers in the US and China remained steadfast in their love for utility vehicles of all stripes. Making a Jaguar SUV became a priority. "The world was telling us in no uncertain terms this is what they wanted," Callum said. "Not to be in the sector would be a little naive for the sake of purity." Jaguar proved its intent two years ago when it revealed the C-X17 crossover concept at Frankfurt, and the final production model is close to the prototype's striking looks. "I thought we managed to maintain that spirit," Callum said. It's a true Jaguar, with cues from the F-Type, 1968 XJ, and other famous models. Who would have thought Jaguar would make an SUV? "I certainly didn't," Callum admitted. But the F-Pace is here. If Callum is okay with it, purists can be, too. Quick Hits Opel retrenches for 2016 and beyond Opel used the Frankfurt show to display its new generation of the Astra, a critical vehicle line for the German division of General Motors.
