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.

Volvo, Daimler, Traton join forces to build electric truck charging network

Volvo Group, Daimler Truck and Volkswagen's AG heavy-truck business the Traton Group announced on Monday a non-binding agreement to build a network of high-performance public charging stations for electric heavy-duty long-haul trucks and buses around Europe. The news was first reported by Reuters. The three major European automakers will invest ˆ500 million (~$593 million USD) to install and operate 1,700 charging points in strategic locations and close to highways. They intend to finalize the agreement by the end of this year and start operations next year, with the hopes of increasing the number of charge points significantly as the companies seek additional partners for the future joint venture. The venture is meant to be a catalyst to prepare for the European Union's goals of carbon-neutral freight transportation by 2050. One of the main deterrents for both individuals and freight companies for switching to EVs has historically been a lack of charging infrastructure. By building that infrastructure, Volvo, Daimler and Traton can also expect to boost their own sales of electric trucks and buses. “It is the joint aim of EuropeÂ’s truck manufacturers to achieve climate neutrality by 2050," Martin Daum, CEO Daimler Truck, said in a statement.  "However, it is vital that building up the right infrastructure goes hand in hand with putting CO2-neutral trucks on the road. Together with Volvo Group and the Traton Group, we are therefore very excited to take this pioneering step to establish a high-performance charging network across Europe.” The partnership between Volvo and Daimler isn't unprecedented. In May, the two competitors teamed up to produce hydrogen fuel cells for long-haul trucks to lower development costs and boost production volumes. This latest venture is another signal that major companies are banding together to solve climate-related issues in the industry. European car industry association ACEA has called for up to 50,000 high-performance charging points by 2030. Traton CEO Matthias Gruendler told Reuters that roughly 10 billion euros would be needed to build out Europe's infrastructure to be fully electrified by 2050. According to a statement released by Volvo, this venture is also a call to action for others with a stake in the industry, like automakers or governments, to work together to ensure the rapid expansion needed to reach climate goals.

Mercedes-Benz releases US-spec 2014 Sprinter details

Last week, Mercedes-Benz released the details for the updated 2013 Sprinter intended for global markets, but this week it has announced what changes are being made to the US-spec version of the van for the 2014 model year, including the Freightliner model. As expected, most of the changes made to the European model will be present on the 2014 Mercedes-Benz Sprinter when it goes on sale in the US, which is expected to be this fall.
The biggest difference between the Sprinter announced last week and the one headed to our shores is what is found under the hood. While European Sprinters will come with diesel engines and offer the availability of a supercharged four-cylinder gasoline or CNG engine, US Sprinters will still offer the 3.0-liter V6 BlueTEC diesel. This year's Sprinter now comes standard with a new base engine, the 2.1-liter four-cylinder BlueTEC diesel. This smaller engine will produce 161 horsepower and 265 pound-feet of torque, and will be paired to a seven-speed automatic transmission; the optional 3.0 V6 puts out 188 hp and 325 lb-ft of torque, and will be mated to a six-speed auto.
Fuel economy for the new Sprinter has not been announced, but Mercedes-Benz has made numerous changes with the goal of improving efficiency. To this end you'll find a new, low-friction rear axle and the optimization for the generator, fuel pump and power steering pump.
