Chevy's smallest wagon subdivides into a two-door open-top Tracker and four-door hardtop wagon. Base models in either four-door or two-door format draw from a twin-cam 2.0-liter four-in-line engine with 127 hp. Tracker's top two four-door wagons tote a 2.5-liter V6 worth ten more points in 2003 for a total of 155 hp. Deluxe Tracker LT is the top version, flashing chrome elements in the front grille and a thick ring of contrasting body cladding around the base as protective armor. Inside, the cockpit applies luxury features including optional leather upholstery. Tracker ZR2 wears wheel flares and charcoal tint on grille and body cladding, plus aluminum wheels and all-season tires. The cabin of ZR2 has convenience features like power windows and power mirrors. For traction on slippery trails away from pavement, Tracker also installs 4WD hardware on several models. It's optional for the four-door LT and standard on ZR2. A two-speed transfer case in the 4WD mechanism brings shift-on-the-fly convenience at highway speed. Other trimmings range from tubular side steps and a brush guard to foglamps, ski and bike racks, and a removable hardtop for the convertible.
