Mercedes teases IAA Concept for Frankfurt

Mercedes-Benz is being coy about the IAA Concept you see above. The Germany automaker admits its name is short for Intelligent Aerodynamic Automobile, but isn't letting out much more. In a very short statement, Mercedes describes the IAA as "two cars in one: an aerodynamics world champion and a four-door coupe embodying irresistible design." Does that mean the IAA points the way forward for the next version of the brand's shapely CLS, which it also refers to as a four-door coupe? Probably, but we're not sure where the "Intelligent" part comes in. Will it be an electric machine that presages a competitor to the Tesla Model S? We'll just have to wait and see. One thing is for certain: The Mercedes IAA looks sleek. While the details of its design are shrouded in strategically placed shadows, we can clearly see a double-bubble roofline that flows seamlessly into a graceful hatch that reminds us of the Audi A7, which isn't a bad design to borrow cues from. The overall shape of the Intelligent Aerodynamic Automobile makes it look like bodywork shrink-wrapped atop the chassis as tightly as possible. We're keen to take a look at the IAA ourselves, and that's going to happen rather soon. Mercedes promises a debut at the Frankfurt Motor Show in the early afternoon (Eastern). Stay tuned. The Mercedes-Benz "Concept IAA" (Intelligent Aerodynamic Automobile) is two cars in one: an aerodynamics world champion and a four-door coupe embodying irresistible design. World premiere. September 14, 7.30 pm (CEST). Featured Gallery Mercedes IAA Concept teasers News Source: Mercedes-Benz via Facebook Design/Style Frankfurt Motor Show Mercedes-Benz Coupe Concept Cars Sedan

The hottest modern sports cars rendered as rally racers

The modern-day World Rally Championship a monumental amount of fun to watch – I should know, as I recently was lucky enough to head to the UK to watch WRC Wales Rally GB – but even the most monstrous of the current WRC cars are based on fairly pedestrian European hatchbacks. Back in the heyday of rally, the Group B era in the 1980s, much hotter cars were the basis of even more incredible competition machines, for the most part. Take the exotic Ford RS200, or the Lancia Delta S4 with its twin-charged engine. And the hatchback-based Group B cars were bonkers, too. So what would some of our favorite modern cars look like if Group B had never ended? A British site named CarWow hired an artist to reimagine everything from the Rolls-Royce Wraith to the Porsche 911 as a retro-inspired rally car, and they were kind enough to let us share the results in the gallery above. The gallery features an Alfa Romeo Giulia in Martini livery, an Audi TT in classic Ur-Quattro colors, a Fiat 500 Abarth sporting massive flares and a hood blister full of auxiliary lights, a new Ford Mustang in RS200 livery, a Lancia Delta in Alitalia colors, a Porsche 911 in Rothmans livery, a Renault-Alpine in classic blue, a Rolls-Royce Wraith tribute to the Jules cologne Corniche Coupe, and a relatively modern-looking VW Touran. So far, the favorite around the office is the incredible Mercedes-Benz S-Class that is an homage to the wonderful 300 SEL 6.8 AMG "Red Pig" that essentially put AMG on the map. Check out the gallery above and see which one you like the best. Related Video:

Jay Leno drives the incredible Mercedes-Benz C111-II concept

You might think that Jay Leno has driven it all, but there are a few vehicles so rare that getting behind the wheel is a special experience, even for him. This week on Jay Leno's Garage, the comedian has one of those unique experiences by taking a ride in a 1970 Mercedes-Benz C111-II concept on loan from the Mercedes Classics Center. First unveiled in 1969, the C111 concept featured an in-vogue wedge shape, gullwing doors, and a mid-mounted three-rotor engine, and it seemed like the supercar of the future. This C111-II went even further in 1970 with tweaked styling and a four-rotor powerplant behind the driver. A V8 eventually replaced the experimental mill, but that switch is also part of the reason this one is still on the road today. Leno gets the full history about Mercedes' original plans for the C111 project, but obviously the real highlight is the rare drive in this vintage concept. He clearly relishes the experience of finally getting behind the wheel of this piece of auto history, one of the few automotive dreams he hadn't yet fulfilled.
