Cd value

In this case the reported CD value must also specify these other relevant factors in order to be meaningful.

The coefficient of drag (Cd value) of the four-door hardtop is 0.38.

Good track geometry including advanced spirals is likely to foster passenger acceptance of higher CD values.

'Preoccupation with Cd values has led to the boring shapes we have become all too familiar with.'

The body kit on the 2.3-16 and 2.5-16 reduced the drag coefficient to 0.32, one of the lowest CD values on a four-door saloon of the time, whilst also reducing lift at speed.
