The main difference is in the length of the vehicle, the Grand Caravan (Long Wheel Base) being longer than the regular Caravan (Short Wheel Base).
For example the 2001 to 2007 models, the SWB: is 113.3 in (2,878 mm) long and the LWB is 119.3 in (3,030 mm) long.
The only difference between the Dodge Grand Caravan and the Dodge Grand Caravan Sport is mostly aesthetic. The side cladding on the Sport model is the same color as the body of the vehicle, the spoiler is visible, and there are other convenience items. It also has a firmer suspension than the Grand Caravan.
