In the lead up to the Frankfurt Motor Show Mercedes-Benz has so far kept quiet when it comes to big-ticket concepts, but now just days before Frankfurt gets into full swing, a shadowy teaser of a new concept has emerged.
Called the Concept IAA, which stands for Intelligent Aerodynamic Automobile, but also a subtle play on words for the Frankfurt show’s official Internationale Automobil Ausstellung title.
Missing from the name is the ‘Vision’ moniker that Mercedes-Benz usually attaches to show cars destined for production. That means that this car is one that will be relegated to show stands, not showrooms.
While the CLS four-door coupe is due to be replaced soon, it's less likely this is the shape it will adopt.
Although the first images are vague, we can see a low-roofed four-door silhouette with bulging rear guards and a twin-dome rear window that terminates in a kamm tail-style rear end.
The brighter, but more tightly cropped rear angle shows a taillight that sweeps from side to side and a three-point star sat atop the bootlid in a style that departs from the current Mercedes-Benz design language.
As the title betrays, the IAA will be focussed on aerodynamic innovations, although to what extent remains to be seen.
The concept’s powertrain is also a mystery for the time being, however a green focus isn’t out of the question so a possible electric motor, aimed at the electric-only Tesla Models S, is a likely candidate.
More info about the Concept IAA will be released at the car’s Frankfurt Motor Show unveiling, Tuesday morning Australian time. TMR will bring you more info as it comes to hand.
