Ford's super wagon starts with the chassis of a super-size F-250 Super Duty work truck, which contains the Super Duty mechanical systems and pulls from one of three Super Duty engines. A wagon's superstructure rises from the Super Duty chassis, with four access doors etched into the side and a tri-panel gate at the rear, plus three tiers of seats, yet still there's more room in the back bay for cargo -- 48 cubic feet. Excursion for 2003 divides into three trims -- XLT, Limited and a new Eddie Bauer series with two-tone exterior. Powertrains consist of gasoline V8 and V10 engines plus a diesel V8. Ford's Triton 5.4-liter V8 is standard with 255 hp, but a 6.8-liter Triton V10 is optional at 310 hp on XLT and standard with Eddie Bauer and Limited. The 7.3-liter Power Stroke turbo diesel worth 250 hp continues as an option, although later in the 2003 model-year Ford will replace it with a new 6.0-liter Power Stroke diesel good for best-in-class 325 hp.
