Chevrolet TrailBlazer is smooth and powerful, with a stunning straight-six engine, a stiff chassis, a sophisticated suspension, powerful brakes and impressive details. It's capable of off-road travel, but feels stable and comfortable on the highway. For 2003, the TrailBlazer adds an extended-wheelbase model with seating for seven, and an optional all-aluminum V8 for more towing power. The fuel tank is larger. And there's even a new North Face Edition with exclusive interior and exterior trim. The V8 delivers strong torque for towing, but the six-cylinder engine delivers plenty of power for the TrailBlazer. The long-wheelbase TrailBlazer EXT sacrifices handling for third-row seating.
