Front/Rear Wing Comparison


Speedway Wings:

Superspeedway Wings

Speedway Rear Wing: The single-element wing consists of the mainplane with no flaps and is used at all speedway events, including the Indianapolis 500. The angle of the mainplane will be between 0 and -10.5 degrees and varies depending on the track. The Wing is designed to add downforce, but limits the car’s speed by adding drag. In 2018, this wing will be used at Indianapolis, Texas and Pocono.

Speedway Front Wing: Single-element wing, consisting of a mainplane and end fence. Wing is used to trim and balance the car. The Verizon IndyCar Series’ minimum wing angles vary by track. In 2018, this wing will be used at Indianapolis, Texas and Pocono.


Short Oval / Road Course Wings:

Road/Street - Short Oval Wings

Short Oval / Road Course Rear Wing: The multi-element wing consists of the mainplane with a vertically stacked flap. The angle of the mainplane is mandated at 0 degrees, plus-or-minus .5 degrees events, while the angle of the top flap varies depending on the track. The wing is designed to provide maximum downforce, but limits the car’s speed by adding maximum drag. This wing will be used at ovals shorter than 1.5 mile long and all road/street courses.

Short Oval / Road Course Front Wing: Multiple element wing consists of a mainplane, upper and lower flaps and end fence. Wing is designed to add downforce, but limits the car’s speed by adding drag. The angle of the mainplane is mandated at 1.92 degrees, plus-or-minus .3 degrees, while the angle of the flaps varies depending on the track. The Verizon IndyCar Series’ minimum wing angles vary by track. This wing will be used at ovals shorter than 1.5 mile long and all road/street courses.
