2014 Mercedes-Benz B-Class ED has 87-mile range, 84 MPGe

Well, that extra weight had to be felt somewhere. With Mercedes-Benz getting ready to start US sales of its B-Class Electric drive this summer, the big question was how well its range would stack up against other electric vehicles sold in the States. Turns out, the Benz is a bit of a juice hog. Let's say up front that the 87-mile single-charge range of the Mercedes-Benz actually stacks up nicely against its competition, since that distance puts the new model right in line with the Nissan Leaf and BMW i3 (we'll ignore the Tesla Model S for a second, here). You can find the numbers at the US Department of Energy's FuelEconomy website. As far as miles per gallon equivalent ratings, though, the Benz's steel frame makes it come up short, as it's about 1,300 pounds heavier than the carbon-fiber-body i3 and about 600 pounds heavier than the Leaf. The B-Class EV has a bigger battery than the i3 or the Leaf (36 kWh compared to 22 kWh for the i3 and 24 kWh for the Leaf) and that's one reason the car gets an 84 MPGe rating, which is about 26 percent less than the Leaf's and 32 percent less than the i3's. But at least the local utility companies will be happy. Mercedes-Benz priced the 177-horsepower B-Class ED in April at $41,450, or $100 more than the i3.

Mercedes-Benz Concept IAA is a modern silver aero

While we English-speaking folk call it the Frankfurt Motor Show, our German friends call this week's bi-annual confab the Internationale Automobil-Ausstellung, or IAA. At first glance, then, you might think Mercedes-Benz named its Frankfurt concept, the Concept IAA, after the show it'd debut at. But, the Concept IAA isn't named for the show. It's actually an abbreviation for Intelligent Aerodynamic Automobile, and it's very aerodynamic indeed. This four-door coupe can transform, while moving, from its sedan-like design mode to an ultra-sleek, gas-powered fish of a car. This aerodynamic mode has a drag coefficent of just 0.19. That's sleeker than a Tesla Model S, and it ties the rating of the General Motors EV1 electric car. In fact, it's very nearly as aerodynamic as the Volkswagen XL1. The IAA can transform automatically at 80 kilometers per hour (about 50 miles per hour) or via the press of a button. When it enters an aerodynamic mode, eight segments at the back of the car extend out, adding over 15 inches to the overall vehicle length, effectively extending its already tear-dropped-shaped tail. And that's just the most visible aero aid. At the front of the car, flaps in the bumper extend out nearly an inch, while there's a smaller extender in the back bumper. These serve to keep air away from the wheel arches, where turbulence can become an issue. Of course, Mercedes has thought of this, too, fitting "Active Rims" that "alter their cupping from 55 mm to zero," whatever that means. There's even an active aero aid inside the front bumper, where a louver extends backward by 2.3 inches to smooth out the air traveling underneath the car. Outside of its super-slippery mode, the IAA is a relatively handsome four-door coupe, featuring the kind of plunging roofline that wouldn't look out of place on the company's pioneering CLS-Class. The interior is certainly worthy of the CLS, too. It's home to gorgeous white leather and touch-based controls, and in general, looks very luxurious. Mercedes' dogged pursuit of aerodynamics does not mean that the Concept IAA is some gutless ecomobile. Under the skin is a gas-powered, plug-in hybrid system that produces up to 279 horsepower and allows the sleek sedan to hit 155 mph. Its all-electric range is based, of course, on what mode its body is in. It's most impressive in aero mode, where it will cover 41 miles on a single charge. Switch over to design mode, and that figure drops slightly to 38.5 miles.

Mercedes introduces the details of the C450 AMG 4Matic

We saw the AMG Sport models joining the C-Class line in Detroit, but Mercedes has waited until the press launch of the Mercedes-AMG C63 to give us the details. In case you've forgotten about how this new puzzle piece fits, there's Mercedes-Benz, there's Mercedes-AMG, then there's the Mercedes-Benz AMG Sport line slotted in between for those who want sporty luxury but not too much of either. This is the second variant in that line-up, and also the second to get V6 power, following the GLE450 AMG Coupe. In the case of the C450 AMG 4Matic, that means a twin-turbo six-cylinder with 367 horsepower and 383 pound-feet of torque, an increase of 38 hp and 29 lb-ft over the C400 4Matic on which it's based. It goes much closer to proper AMG territory with its looks and features, with that sharp, chrome-trimmed lip in front, the oblong lower intakes, lightweight wheels, and a "special AMG badge" on the front fenders. In back, the sedan gets a spoiler on the trunk, the wagon gets a roof spoiler. There's a suspension highly derivative of that on the C63 AMG, with three-stage dampers. So too the five drive modes laid out like on traditional AMGs, the 7G-Tronic automatic transmission, the ESP with Curve Dynamic Assist, and it will even sound close to an Affalterbach special thanks to a sports exhaust. Cabin occupants can play the real deal with sport seats and a flat-bottomed wheel with red cross-stitching. We don't have a price yet, but there will probably be plenty of room between the price of the AMG C63 and the $48,950 C400 4Matic to make buyers happy. The press release below has all the info.

The new C 450 AMG 4MATIC expands the product range of the sports car and performance brand within Mercedes-Benz with another new AMG sports model. As an attractive entry into the world of AMG, the C 450 AMG 4MATIC combines a 270 kW (367 hp) 3.0-litre V6 biturbo engine with a permanent Performance all-wheel-drive system and sophisticated suspension technology adopted from the Mercedes-AMG C 63. This all results in fascinating driving performance and the hallmark emotional expressiveness of the brand.
