The top speed of a GMC Sierra varies by model and engine type, but most versions can reach speeds between 100 to 120 miles per hour. The high-performance Sierra Denali and models equipped with the 6.2L V8 engine may achieve higher speeds. However, it's important to note that real-world driving conditions and legal speed limits should always be prioritized over maximum speed capabilities.
