Mercedes Concept IAA shows its mighty morphing aero aids

Modern supercars are utilizing more active aerodynamic elements that constantly adjust, to make them some of the fastest things on the road. The Mercedes-Benz Concept Intelligent Aerodynamic Automobile is using them too, but the know-how is applied here for ultimate efficiency rather than turning better lap times. In the standard design mode, the four-door luxury coupe looks like a CLS from the near future with styling that's mixed with a little of the F 015 concept. However at the press of a button or upon hitting about 50 miles per hour, the IAA transforms into aero mode to have an insanely low drag coefficent of just 0.19. To achieve the ultra-efficient shape, the rear of the concept stretches over 15 inches to guide air down the tail. Flaps in the bumpers also extend outward, and the wheels adjust to improve the flow around the sides. To trim things out underneath, a portion inside the front bumper moves, as well. Inside, passengers sit in organically shaped leather seats, but occupants have to look at a vast array of purple and blue LED accent lights. The big panoramic roof is a nice touch, though. It would be interesting to watch water tumble over this slippery shape when driving in the rain. To maximize efficiency, Mercedes powers the IAA with a plug-in hybrid that's hooked up to a gasoline engine. The result is 275 horsepower and an electronically limited top speed of 155 miles per hour. On the European testing cycle, the company figures the concept could cover 41 miles solely on electric power in aero mode. Showing the gains of the swoopy transformation, that figure falls to 38.5 miles in design mode.

Weekly Recap: Autonomous driving goes commercial in Nevada

Nevada granted Daimler Trucks North America the first license to run an autonomous commercial vehicle on public roads in the United States Tuesday, marking another milestone in the technology's rapid advancement. Gov. Brian Sandoval and Daimler truck chief Wolfgang Bernhard promptly used the license to lap Highway 15 near Las Vegas in a newly revealed Freightliner Inspiration Truck. It was a clear signal that autonomous driving is big-rig reality, though it's still a long way from widespread use. Nevada certified two of Daimler's Freightliner Inspiration Trucks, which use the company's Highway Pilot system with a stereo camera, radar, and lane-keeping collision-prevention features to regulate the brakes and steering. The radar component has a long-range sensor that can cover 820 feet at an 18-degree angle and a shorter-range unit that stretches 230 feet at a 130-degree angle. The Inspiration trucks are based on the existing Freightliner Cascadia Evolution model used on US roads. In addition to the autonomous technologies, it also has futuristic design cues, including blue lighting in the front and a new hood and grille. While there are only two Freightliner Inspiration trucks in existence, Daimler expects to bring the Highway Pilot system into mass-produced big rigs by 2025, in time to capitalize on the market's predicted growth. The German truckmaker predicts the global hauling market will triple by 2050, and the United States will be a key part of that growth. Trucks carry 69.1 percent the nation's domestic freight tonnage and hauled 9.7 billion tons of freight in 2013, according to the American Trucking Association. Daimler expects autonomous driving to augment this growth, and perhaps evolve the role of the truck driver. Still, the company points out autonomous tech is not meant to replace drivers, but to assist them and relieve fatigue and monotony on long hauls. The driver has to stay in control for passing, in city traffic, and when hooking up the trailer. The company said autonomous driving also offers the potential for improved fuel economy – tests showed a five-percent gain – and lower maintenance costs. Daimler also said the technology could reduce congestion on the road. Much of this is attributable to the constant flow of traffic, which is aided by autonomous driving. While the benefits are becoming increasingly apparent, autonomous technology is still met with skepticism.

Mercedes-AMG teases C63 coupe

Thanks to a recently leaked presentation slide, the cat is already out the bag when it comes to the attractive styling of the Mercedes-AMG C63 Coupe. Still, Mercedes' long series of teases for the upcoming two-door's design continues in a new video. Unlike the last brief teaser, this latest clip shows the coupe completely free of camouflage. Although, the editing is so quick in the 15-second clip, you never really get a strong glimpse at the future model beyond its front bumper. Not that we're complaining about another opportunity to hear the growl from the 4.0-liter, twin-turbo V8. After several videos and galleries of images with various looks at the new model, the wait to learn everything about the C63 Coupe is nearly over – the official reveal comes on August 19. All signs suggest that the two-door will offer the same choice as the sedan between 469 horsepower and 479 pound-feet of torque or 503 hp or 516 lb-ft versions of the twin-turbo V8 with a seven-speed gearbox.
