“Every surface, body opening, and vent on and under Mustang GTD’s body is functional,” said Mustang GTD chief program engineer Greg Goodall. “Some air is directed for cooling, other for aerodynamics and downforce. All of it to help GTD go faster or stick to the pavement no matter what the conditions are.”
But while the GT3 RS variably adjusts both wings to maintain a constant 30:70 front-to-rear balance, Ford simply says that “the DRS closes the main wing element and flap to create an integrated airfoil to generate additional downforce at the rear,” while at the front, the keel shape of the underbody helps to evacuate incoming air through the vented front fenders, creating an area of low pressure that sucks the car to the floor. But it still looks like the Mustang GTD’s balance is always optimized.
