In the midsize SUV segment, Chevrolet has long been frustrated, watching Ford steal the show with the Explorer. The 2002 TrailBlazer is Chevy's best shot at reversing that order. It's a total redesign, including a stunning new straight-six engine, stiffer and lighter chassis, sophisticated suspension, powerful brakes and impressive details. The vehicle's 40-month planning and execution was done in a careful, creative, thorough and extremely bold manner. According to GM engineers, the TrailBlazer exceeds all the targets that had been set for it. Based on the specs and early performance, that claim is easy to believe.
