AN ANALYSIS OF THE IMPACT OF SPORT UTILITY VEHICLES IN THE UNITED STATES

It may be labeled sport utility vehicle, SUV, sport-ute, suburban assault vehicle, or a friend of OPEC (Organization for Petroleum Exporting Countries). It has been the subject of comics, the object of high-finance marketing ploys, and the theme of Dateline. Whatever the label or the occasion, this vehicle is in great demand. The popularity of sport utility vehicles (SUVs) has increased dramatically since the late 1970s, and SUVs are currently the fastest growing segment of the motor vehicle industry. Hoping to gain market share due to the popularity of the expanding SUV market, more and more manufacturers are adding SUVs to their vehicle lineup. One purpose of this study is to analyze the world of the SUV to determine why this vehicle has seen such a rapid increase in popularity. Another purpose is to examine the impact of SUVs on energy consumption, emissions, and highway safety.

Investigation of Class 2b Trucks

The popularity of trucks in the class 2 category--that is, those with a 6,000 to 10,000 pounds (lbs) gross vehicle weight rating (GVWR)--has increased since the late 1970s/early 1980s. The purpose of this research is to identify and examine vehicles in the upper portion of the class 2 weight range (designated as vehicle class 2b) and to assess their impact. Vehicles in class 2b (8,500-10,000 lbs GVWR) include pickup trucks, sport utility vehicles (SUVs), and large vans (i.e., not minivans). Oak Ridge National Laboratory researched each individual truck model to determine which models were class 2b trucks and arrived at four methodologies to derive sales volumes. Two methods--one for calendar year and one for model year sales--were recommended for producing believable and reliable results. The study indicates that 521,000 class 2b trucks were sold in calendar year 1999--6.4% of sales of all trucks under 10,000 lbs. Eighty-two percent of class 2b trucks sold in 1999 were pickups; one third of class 2b trucks sold in 1999 were diesel. There were 5.8 million class 2b trucks on the road in 2000, which amounts to 7.8% of all trucks under 10,000 lbs. Twenty-four percent of the class 2b truck population is diesel. Estimates show that class 2b trucks account for 8% of annual miles traveled by trucks under 10,000 lbs and 9% of fuel use. Data on class 2b trucks are scarce. As the Tier 2 standards, which apply to passenger vehicles in the 8,500-10,000 lb GVWR category, become effective, additional data on class 2b trucks may become available--not only emissions data, but data in all areas. At the moment, distinguishing class 2b trucks from class 2 trucks in general is a substantial task requiring data on an individual model level.

Sales and Impact of Class 2b Trucks

Vehicles in the upper portion of the Class 2 weight range [6,000 to 10,000 lb gross vehicle weight rating (GVWR)] were identified and examined, and their impact was assessed. Class 2b vehicles (GVWR of 8,500 to 10,000 lb) include pickup trucks, sport utility vehicles, and large vans. Oak Ridge National Laboratory researched each individual truck model to determine which models were Class 2b trucks and developed four methodologies to derive sales volumes. Two methods were recommended for producing believable and reliable results. The results of the study indicate that in calendar year 1999, 521,000 Class 2b vehicles (6.4% of sales of all trucks under 10,000 lb) were sold; 82% of Class 2b vehicles sold were pickups, and one-third of Class 2b vehicles sold had diesel engines. In 2000, 5.8 million Class 2b vehicles (7.8% of all trucks under 10,000 lb) were on the road; 24% of the Class 2b vehicle population had diesel engines, and Class 2b vehicles accounted for 8% of annual miles traveled by trucks under 10,000 lb and 9% of fuel use. Data on Class 2b vehicles are scarce. As the Tier 2 standards (which apply to passenger vehicles in the 8,500 to 10,000 lb GVWR category) become effective, additional data—not only about emissions, but also about all areas—on Class 2b vehicles may become available. At the moment, distinguishing Class 2b vehicles from all Class 2 vehicles is a substantial task that requires individual model data.
