Mercedes teases IAA Concept for Frankfurt

Mercedes-Benz is being coy about the IAA Concept you see above. The Germany automaker admits its name is short for Intelligent Aerodynamic Automobile, but isn't letting out much more. In a very short statement, Mercedes describes the IAA as "two cars in one: an aerodynamics world champion and a four-door coupe embodying irresistible design." Does that mean the IAA points the way forward for the next version of the brand's shapely CLS, which it also refers to as a four-door coupe? Probably, but we're not sure where the "Intelligent" part comes in. Will it be an electric machine that presages a competitor to the Tesla Model S? We'll just have to wait and see. One thing is for certain: The Mercedes IAA looks sleek. While the details of its design are shrouded in strategically placed shadows, we can clearly see a double-bubble roofline that flows seamlessly into a graceful hatch that reminds us of the Audi A7, which isn't a bad design to borrow cues from. The overall shape of the Intelligent Aerodynamic Automobile makes it look like bodywork shrink-wrapped atop the chassis as tightly as possible. We're keen to take a look at the IAA ourselves, and that's going to happen rather soon. Mercedes promises a debut at the Frankfurt Motor Show in the early afternoon (Eastern). Stay tuned. The Mercedes-Benz "Concept IAA" (Intelligent Aerodynamic Automobile) is two cars in one: an aerodynamics world champion and a four-door coupe embodying irresistible design. World premiere.

Chris Harris falls in love with Mercedes-AMG GT at Laguna Seca

It's not every day that an automaker goes down a market segment and still comes off as even more ambitious, but that's exactly what Mercedes has done with the new AMG GT. While the SLS was bigger and more expensive, with the new GT, Mercedes has set its sights on one of the most iconic sports cars of all time. That, of course, would be the Porsche 911, and the big question is whether Benz has achieved its target. For the answer, we turn to none other than the Monkey himself – the inimitable Chris Harris, who recently went solo with his own YouTube channel. And for his latest segment, he took the latest German sports car around no less suitable a track than Mazda Raceway Laguna Seca.

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.
