As we said earlier, a low drag could mean more lift, hence more drag means more downforce. Important to note is the fact that the drag coefficient is a highly volatile figure.

Wearing Z06 bodywork, a ZR1 front splitter and side skirts, along with an aftermarket hood and rear spoiler, the C6 started off with a drag coefficient (CD) of 0.373, an overall lift coefficient ...

Wind Engineering, Vol. 15, No. 5 (1991), pp. 240-246 (7 pages) In the present paper a study of the drag and lift coefficients of the Savonius rotor has been carried out for different Reynolds numbers.
