NASCAR takes six Cup cars to wind tunnel after Michigan

In the wind tunnel NASCAR will find just how bad the Chevy Camaro is aerodynamically and why the Chevy teams are out to lunch

NASCAR has taken six Cup cars – two from each manufacturer – for wind tunnel and engine testing following Sunday’s race at Michigan.

The cars taken include the Fords of Harvick and Brad Keselowski (finished second); the Chevrolets of Austin Dillon (fourth) and Chase Elliott (ninth); and the Toyotas of Kyle Busch (third) and Denny Hamlin (eighth).

Steve O’Donnell, NASCAR’s chief racing development officer, discussed the wind tunnel tests Monday on SiriusXM NASCAR Radio’s “The Morning Drive."

“We try and find a track where obviously aero is going to play a bigger role," O’Donnell said. “I think (the test) it’s actually Tuesday. We’ll have those results kind of going into Wednesday and our process is to share that with (manufacturers) and the race teams. It’s a good barometer for us for two things. To make sure we’re still within that box that we set for the current year and probably most importantly is we look to lock in 2019 (that) the baseline we’re using matches up with all the data that we believe we have in the system. It’s a good check on both for not only ’18 but future race packages as well."
