TOLEDO, OHIO — For the first time, trucks account for over half of all vehicle fuel consumed in the United States, according to research from Havill’s new multi-client study entitled: “The U.S. Commercial Fleet Market Forecast, 2004-2008.” Since the late 1990s, the number of trucks on the road has grown at over twice the rate of the overall vehicle population. The study series began in 1995 and has become one of the industry’s primary sources for planning data on trends impacting the commercial fleet market. Between fall 2004 and spring 2005, over 1,100 executive telephone interviews were conducted with fleet administrators across the country. Fuel is only one topic covered in this comprehensive industry study. Other topics include: vehicle procurement and leasing; advance vehicle and fuel technologies, including hybrids; on-site and off-site fueling, tires, maintenance, and payment methods; leasing programs; and fleet administration practices, including safety, insurance, and the use of telematics. The complete study will be published in August 2005.
