* Specific trim level: Different trim levels might have slightly different aerodynamic features.
* Testing methodology: Different testing facilities and methods can produce slightly different results.
* Condition of the vehicle: Things like added accessories (roof racks, spoilers) will affect the Cd.
You won't find this information readily published by Dodge. Automotive manufacturers don't always release precise Cd figures for all models. To get a close approximation, you'd need to find independent aerodynamic testing data for a 2002 Grand Caravan, which is unlikely to be easily accessible.
In short, while you can't find a precise number, you can expect the drag coefficient of a 2002 Dodge Grand Caravan to be in the range typical for minivans of that era – likely somewhere between 0.35 and 0.40. This is an estimate; it's not a precise value.
