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?

Great test and hospitality from @kansasspeedway, learned a ton. Three days of hard work from everyone involved. Off to Montreal.
