This study seeks to examine the relationship between the price of gasoline and the demand for larger fuel inefficient vehicles such as full SUVs and pickup trucks. Various industry specialists have studied the vast decrease in sales for U.S. automakers; in particular, large SUV sales over the past six years and many analyst attributed the changes to the corresponding rise in the price of gasoline.
