Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.

Mercedes-AMG gears up for 2016 DTM with new C63 Coupe

Mercedes was once a force to be reckoned with in DTM. The Silver Star marque won six drivers' championships and nine constructors' titles since the modern Deutsche Tourenwagen Masters series rebooted in 2000. But though it's currently leading the standings, the last time it won the championship was in 2010. Audi and BMW have traded bragging rights each year since. What you see here, then, is the vehicle by which Benz hopes to recapture its former glory in the German tin-top racing series. Presented alongside the Edition 1 at the Frankfurt Motor Show, the new touring car is based – stylistically at least – on the new C63 AMG Coupe, but is designed specifically for the race track. Underneath the largely carbon-fiber bodywork sits a 4.0-liter V8 engine driving 483 horsepower and 369 pound-feet of torque through a six-speed sequential gearbox to the rear wheels. It's suspended by pushrod-actuated by double wishbones and features a mechanical diff (but no traction control) and carbon-ceramic brakes (but no ABS). In short, the new C63 is all business. And it looks about ready to take on Germany's most famous racing circuits and those of some of its neighbors – from Hockenheim, the Nurburgring, and the EuroSpeedway Lausitz to Zandvoort, the Red Bull Ring, and the Moscow Raceway. Audi and BMW had better watch their mirrors. Mercedes-AMG DTM Team present 2016 race car - Looking ahead to the 2016 season: How the new DTM car fielded by the Mercedes-AMG DTM Team will look - Inspired by the DTM: AMG launch Edition 1 Mercedes-AMG C 63 Coupe - Five questions to Head of Mercedes-AMG DTM Ulrich Fritz - Overview: How Mercedes-Benz DTM vehicles have evolved - Ulrich Fritz: "Our aim with this vehicle is, of course, to continue the Mercedes-Benz success story in the DTM." The 2015 DTM season reaches its climax in September. But even before the final three race weekends of the year at Oschersleben, the Nurburgring and Hockenheim, the Mercedes-AMG DTM Team are providing an insight into what lies ahead for the race series, revealing the new car that they will enter for the 2016 campaign. Design adaptations to the 2016 Mercedes-AMG C 63 DTM first began last year. The dynamic-looking headlights and the twin blade grille typical of the AMG are two of the car's most striking features. The first tests with the new vehicle will take place during the winter as part of preparations for the 2016 season.

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.
