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 FWD platform to last until 2018, convertible and two-seater future uncertain

Mercedes-Benz seems to be expecting a lot of success from its front-wheel-drive CLA-Class. Automotive News is reporting that the sub-C-Class sedan could grow when its second generation arrives in 2018.
The current FWD platform for MB underpins the CLA, the B-Class, the GLA-Class, and the A-Class. The B-Class will arrive in North America as an EV for spring of 2014, while the production GLA crossover will arrive three to four months after that. The five-door A-Class won't be crossing The Pond. Sad faces all around.
According to AN, another model will be based on the front-drive architecture, but it won't be coming to the US market. Set to arrive next year, rumors are that it'll be a wagon version of the CLA, sort of like the ill-named five-door CLS Shooting Brake that is also a Europe-only item.

Recharge Wrap-up: Mercedes stationary batteries, 2015 E-Mazing Race

Mercedes-Benz is following Tesla's Powerwall in selling stationary batteries for home, business, and industrial solar energy storage. The lithium-ion batteries will come in 2.5- and 5.9-kWh capacities, and can be linked together. Daimler's vehicle battery technology, "has proven to work for millions of driven kilometers in the toughest environments of heat and cold, which makes it the best candidate also for stationary use," says Harald Kroeger of Mercedes-Benz. Pricing is unavailable as of yet, but Mercedes promises "competitive" pricing when the batteries go on sale at the Intersolar trade fair (June 10 through 12) in Munich, Germany.

The race challenges drivers to earn the most points by charging at Sun Country Highway charging stations in a month. Contestants needn't have been at the official starting point nor cross the finish line; they just needed to sign up and download the race app to participate. More remote charging stations offer more points when charging, and participants can also win prizes for photos and using social media. The 2015 E-Mazing Race, which began May 27 and ends June 24, is meant to raise awareness of electric vehicles. Sun Country is working on expanding its EV charging infrastructure in the US, so don't be surprised to see the race encompassing most of North America in the future. Read more at Green Car Reports. Linde has opened a new hydrogen fueling station in Innsbruck, Austria. The station, located in the popular destination city that has twice hosted the Winter Olympics, will allow hydrogen-powered vehicles to cross the Alps and travel between Italy and Germany. The station is capable of 700-bar refueling and can fuel six cars per hour. It was built as part of the HyFive project to create hydrogen fueling infrastructure across Europe to facilitate the rollout of fuel cell vehicles. It is the second public hydrogen station in Austria. Read more at Green Car Congress, or in the press release below from Linde.
