Nascar’s Screech and Slam? It’s All Aerodynamics

To prepare the drivers for the “Car of Tomorrow” being introduced at the 50th running of the Daytona 500 this Sunday — billed with characteristic stock car understatement as “the Most Anticipated Event in Racing History” — the racing teams’ engineers have spent the winter testing their versions of the new car in wind tunnels and running huge computer simulations called C.F.D.’s (for computational fluid dynamics).

To understand what is happening on the track and in the garage here at Daytona, you need either a crash course in aerodynamics or the guidance of Dr. Leslie-Pelecky and her new book, “The Physics of Nascar," according to The New York Times.
