The 2001 GMC Sierra C3 represents the early years of the Sierra's third generation. The Sierra C3 is equipped with a potent 6.0-liter V8 engine that produces 325 horsepower and 370 lb-ft of torque. This powertrain is teamed with a four-speed automatic transmission, and all Sierra C3 models come with an all-wheel-drive system, unusual for its class. This model distinguishes itself from other Sierra models with a standard 'Autotrac' transfer case, lower suspension, and OnStar system. Inside, the C3 caters for comfort with leather seats and Bose sound system. However, its safety offerings were modest for its era, primarily focusing on airbags and ABS without the advanced driver assists found in later models.
