An experimental low downforce car made its on-track debut during Wednesday's test session at Kansas Speedway.

A wind tunnel picture of the car first surfaced last week on Instagram, sparking the curiosity of fans -- and driver Brad Keselowski. According to the aerodynamics/vehicle performance engineer who posted the picture, the car has the potential to be "the least aero sensitive car of the modern era."

So how did it go?
