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.

Recharge Wrap-up: Mercedes gets F1 efficiency, EV charging in Vermont, VW e-Golf to use Bosch

Efficiency equals performance, especially in the case of Formula 1 racing. The Mercedes AMC Petronas team points to several key efficiency technologies it uses to get the most out of its cars. And if their utter dominance so far this season is testament to this relationship, perhaps we should pay attention. Mercedes highlights hybrid tech, turbocharging, aerodynamics, lightweight construction, tribology (both in making internal components and lubricants more slippery) and simulation as crucial to getting around the track faster than anyone else. These just happen to be some of the same things that make the cars we drive on public roads more fuel-efficient. Learn more in the press release below. It's a good read. Brammo, maker of sweet electric motorcycles, is teaming up with TEAM Industries to make drivetrains for electric vehicles. TEAM, which specializes in drivetrain technology, will also become an investor in Brammo as part of the partnership. "The electric vehicle market is a growth market," says TEAM CEO and President David Ricke, "and TEAM and Brammo will be providing a wide range of solutions for OEM manufacturers." Read more over at EV World. Vermont celebrated the installation of a new EV charging station as part of a Green Energy Corridor between Boston and Montreal. When finished, drivers will be able to make the whole trip in an EV with access to charging along the way. For $5, customers can charge their vehicle in about 30 minutes at the Red Hen Baking Company in Middlesex. There are currently only about 700 EVs on the road in Vermont. The state has a goal to get 90 percent of its energy from renewable sources by 2050, and getting more EVs on the road is crucial to that mission. Vermont hopes that expanding the charging infrastructure will convince more people to go electric. Read more at Vermont Public Radio's website. For it's new e-Golf, Volkswagen will use Bosch chargers for home installation and ChargePoint stations at its dealerships. Bosch will have various 240-volt options for the home, and will also provide installation. e-Golf customers will also get a free ChargePoint membership, and will have access to the company's network of charging stations worldwide. The 2015 e-Golf goes on sale in the US later this year. Read more in the press release below.

Petrolicious profiles mustard 1972 Mercedes-Benz 280 ready to go anywhere

The Mercedes-Benz sedans of the '70s and early '80s are certainly attractive models, but with their hard lines, the four-doors really don't have the graceful curves usually associated with a beautiful car. Instead, it's much more accurate to call these classic Germans handsome. The W114 chassis especially has a powerful stance about it with an upright grille dominating the front and long, flat surfaces elsewhere. Petrolicious takes a look at one man's journey to restore one of these posh vehicles in its latest video. Bernard Bredehorn grew up in the back of his grandparents' W116-chassis Mercedes 280 SE, and when he eventually got a classic of his own, Bredehorn ended up with a 1972 Mercedes 280. However, the sedan was in need of a complete restoration and sat for years in a friend's garage buried under parts. Bredehorn eventually excavated the car and brought it back to life in a very '70s shade of mustard yellow. Petrolicious shows why this classic Mercedes is now happy eat up many trouble-free miles on Germany's roads.
