Another concept car that caught attention in Frankfurt was the Mercedes Intelligent Aerodynamic Automobile. A one-off showcase of the brand’s aerodynamic prowess, it boasts a drag coefficient of just 0.19. To accomplish this unprecedented level of slipperiness, Mercedes has developed a dynamic, adaptable body structure that literally changes shape with the push of a button. Even the wheels reduce their indentation to become completely flat, allowing air to slip down the car’s sides. The Frankfurt Motor Show shouldn’t disappoint car fans, with new models for 2015, 2016 and beyond, as well as forward-thinking concepts for the automobile of tomorrow.
