NASCAR tries to combat heat at Michigan

By AMANDA VINCENT

NASCAR issued a rules bulletin to Sprint Cup Series teams on Wednesday mandating extra air ducts on the right-side window of cars for competition Sunday at Michigan International Speedway in Brooklyn, Mich.

According to Wednesday’s bulletin, a dual outlet duct will be required on the right-side window of the car, increasing the number of right-side openings to three. At other tracks, extra openings aimed at cooling drivers are optional and will remain optional beyond the Michigan race.

The change comes as a result of heat exhaustion concerns during the Brickyard 400 race weekend last month at Indianapolis Motor Speedway, specifically during the NASCAR Xfinity Series race at the track. Teams will run with the same high-drag aerodynamic rules package at Michigan that they did at Indianapolis, a rules package that decreased the amount of air getting inside the car to the driver.

Speeds at Michigan are expected to be higher than speeds at Indianapolis last month, but those higher speeds are expected to increase engine heat, resulting in higher cockpit temperatures.

The Xfinity Series is racing at Mid-Ohio Sports Car Course on Saturday instead of running a companion event to the Sprint Cup Series at Michigan. The NASCAR Camping World Truck Series will race at Michigan on Saturday, but is not affected by the rules change.
