The Toyota GR Yaris - The Aerodynamic Performance

Source: AutoMotoTV (Glomex)

In order to achieve the best possible aerodynamic performance, the GR Yaris, which is otherwise based on the hatchback model, was given another unique selling point: a three-door instead of five-door body with a flatter roof line that tapers towards the rear. It optimizes the airflow to the rear wing. In modern rally cars - which must correspond to the production model in these points - this important detail helps to generate as much downforce as possible on the rear axle. As with the competition model, the design of the lower body area of the production version also ensures an efficiently channelled air flow along the vehicle flanks.
