Major changes included:

After some model confusion through the late-1990s and early-2000s -- between the incoming Sierra and outgoing C/K pickups -- the Sierra 3500 officially debuted in 2001. It came standard with a base 6-liter V8 with 300 horsepower and had a pair of optional engines: a 6.6-liter diesel with 300 horsepower and an 8.1-liter V8 with 340 horses. For 2003, GMC revised the Sierra 3500's front fascia and modified the base engine to run on CNG or gasoline. The 2006 3500 received a revised 6.6-liter diesel that pushed out 360 horsepower and 650 pound-feet of torque.
