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.

Automakers suspend some business in Russia following invasion

(Getty Images)   Global auto and truck makers, including Sweden's Volvo Cars and Germany's Daimler Truck, on Monday suspended some business in Russia following that country's invasion of Ukraine. Russian forces invaded Ukraine last week, marking the biggest attack by one state against another in Europe since World War II. Many firms have idled operations in Russia following Western sanctions against Russia. Energy giant BP Plc, Russia's biggest foreign investor, abruptly announced over the weekend it was abandoning its 20% stake in state-controlled Rosneft at a cost of up to $25 billion. On Monday, Swedish automaker Volvo Cars said it would suspend car shipments to the Russian market until further notice, becoming the first international automaker to do so as sanctions over the invasion continue to bite. In a statement, the company said it had made the decision because of "potential risks associated with trading material with Russia, including the sanctions imposed by the EU and US." "Volvo Cars will not deliver any cars to the Russian market until further notice," it said. A Volvo spokesman said the carmaker exports vehicles to Russia from plants in Sweden, China and the United States. This came as Russia warned Sweden and Finland not to join NATO or risk facing “serious military-political consequences." Volvo sold around 9,000 cars in Russia in 2021, based on industry data. Earlier on Monday, RIA news agency reported Volkswagen had temporarily suspended deliveries of cars already in Russia to local dealerships, citing a company statement. VW had no immediate comment when contacted by Reuters. VW previously said it would halt production for a few days this week at two German factories after a delay in getting parts made in Ukraine. Daimler Truck said on Monday it would freeze its business activities in Russia with immediate effect, including its cooperation with Russian truck maker Kamaz. Mercedes-Benz Group is also looking into legal options to divest its 15% stake in Kamaz as quickly as possible, the Handelsblatt newspaper reported. A Mercedes spokesperson told Reuters business activities would have to be re-evaluated in light of the current events. Mercedes-Benz Group, formerly Daimler AG, was the parent company of Daimler Truck before the truck maker was spun off.
