Consumer Guide® Road-Test Evaluation
GMC Sierra and Chevrolet Silverado pickups outperform their predecessors, if not dramatically so. All-around performance easily matches Ford's F-150. New V8s are smooth and capable, but yield slightly less torque than previous engines, so acceleration and throttle response are similar. The Tow/Haul mode and optional adjustable suspension are welcome features, since most big pickups haul or tow at times. Although it's a smooth runner, the V6 struggles under heavy loads or up long grades. The 5.3-liter V8 offers good power under all conditions, though it trails Ford's 5.4 liter in torque. An alert, fuss-free automatic transmission helps. A 2WD Sierra with the 5.3 V8 averaged 12.6 mpg. Brakes deliver good stopping power with firm, progressive pedal action, unlike the previous model's mushy feel. Steering is more precise, if overboosted. The Quadrasteer 4-wheel steering system, made available in 2002, is a revelation, giving this big pickup the close-quarters maneuverability of a small car as well as enhancing high-speed tracking and towing stability. A stiffer structure helps improve ride quality, which is more compliant than Ford's, though the tail still stutters over bumps when the bed is empty. Road, wind, and engine noise levels are mild. In design, feel, and location, gauges and controls are best-in-class. GM also supplements the odometer with an engine-hour meter. Front seats are roomy and supportive. Integrated seatbelts move comfortably with the seats themselves. Some drivers might have trouble squeezing between the door panel and seat, to reach some controls. A Sierra or Silverado soundly trounces Ford and Dodge pickups in rear-seat accommodations, with more leg clearance. A contoured cushion and reclined backrest approach sedanlike comfort, and doors open wider.
Value for the Money
General Motors refined its big pickups capably, while introducing plenty of worthy improvements. No extended-cabs are more comfortable. Both makes deliver high value for performance, comfort, and design, and beat Ford in 4WD convenience. GMC models tend to cost just a tad more then Silverados. Few C3 models are likely to be found, and they'll be expensive.
