The Ford Excursion was the largest SUV in the Ford line up from years 2000 to 2005. Classed as a heavy duty pickup truck and built on that platform, it was one of the most popular SUV selected for conversion to a limousine. Classified as a heavy duty vehicle, the Excursion was exempt from Corporate Average Fuel Economy regulations.
Initially the Excursion had a 7.3 Liter Powerstroke diesel engine . This engine was undersized for the weight of the vehicle and the Excursion was heavily critized for its poor fuel economy which ranged about 12 mpg for city driving and 14 mpg for the highway. Ford was slow to rectify the problem and not until 2003 was this engine replaced with a more powerful 6.0 Liter Powerstroke diesel engine. With the addition of this new engine, power and fuel economy increased and noise levels were reduced.
Originally the Excursion had a four speed automatic transmission but this was upgraded to a five speed automatic in 2003. This was the same year that the Eddie Bauer Excursion was introduced with an upscale trim package.
The Exursion was discontinued in 2007 as Ford needed to free up capacity at the Louisville plant that produced the Super Duty pick up trucks. A more fuel efficient extended length Expedition was designed and the Excursion was dropped from the line up.
