Under the Hood
General Motors offers a selection of five engines to accommodate a variety of cargo- and passenger-hauling requirements. Choices begin with a 200-horsepower, 4.3-liter V-6 for the G1500 van. Depending on the model, a 220-hp, 5.0-liter V-8 or a 255-hp, 5.7-liter V-8 are the standard powerplants for G2500/3500 vans. Options for heavy-duty models include a new 340-hp, 8.1-liter Vortec 8100 V-8, replacing the 7400 engine. GMC claims that the new 8100 engine is more economical than its predecessor. A 195-hp, 6.5-liter diesel V-8 also is available.
All models have a four-speed-automatic transmission. When properly equipped, a G1500 van can tow as much as 7,300 pounds, while the G3500 diesel can pull as much as 10,000 pounds. This year’s engines have a new powertrain control module and a more efficient alternator, and automatic transmissions for heavier-duty models have received some internal enhancements.
Four-wheel antilock brakes are standard, and side-impact airbags are not available.
