The Ford Expedition was introduced in August 1996 as a 1997 model, replacing the 2-door Ford Bronco.
The original 1997 Expedition was available in two trim levels -- XLT and Eddie Bauer. Standard was a 4.6-liter V8 engine with 215 horsepower, with either rear (4x2) or 4-wheel drive (4x4). An optional 5.4-liter engine with 230 horsepower was also available.
Exclusively for 1998, the optional 5.4-liter engine was upgraded to 235 horsepower.
For 1999, the 5.4-liter engine (now with 260 horsepower on all models) became standard on the 4x4 Eddie Bauer.
In addition, the 4.6-liter engine, still standard on all other models, was upgraded to 240 horsepower. This engine remained the same until 2000.
