NASCAR has reinvented the windshield wiper ... but not for rain
Fox News
NASCAR Cup Series teams are using their windshield wipers as an aerodynamic device even when it isn't raining.
That is to say, the motor mechanism for a wiper is mandatory, but the teams don't have to install the blade if the conditions are dry like they were this year, after the deluge that hit the track in 2021. All the cars had them, however, but for a different reason than clearing away water.
The teams have found ways to use them as an aerodynamic device to help direct the flow of air over the body of the car by parking them at an angle in a vertical position. A few teams, including Joe Gibbs Racing and Team Penske, even covered their wipers in boxes to enhance the effect.
