GMC Sierra 1500 Summary

The GMC Sierra 1500 is as sturdy and reliable as pickup trucks get. New models are geared out with the latest technology, and the six engine-transmission combinations on offer allow you to find the exact specifications to meet your needs.

The 1500 can tow up to 12,200 lbs and carry a payload of 2,140 lbs, meaning it can cope with all but the biggest hauling challenges. The downside to all that toughness is relatively high fuel consumption at around 11.8 L/100 km—but the Sierra 1500 gets the job done.
