Newer Caravans get decent gas mileage on the highway, and relatively poor mileage in the city. Caravan gas mileage really has a ways to go considering what many other competing manufacturers are doing. However, the Caravan is a minivan, historically among the worst choices for gas mileage. 2010 Caravan gas mileage is about 24-25 MPG highway, depending on the model, and 16-17 city, depending on the model. If Caravan gas mileage is important to you, you might consider another vehicle. However, for most purchasers, Caravan gas mileage is not as big a priority as the convenience and family features of a minivan.
