GMC created an upscale version of its Sierra 1500 in 2001 called the Sierra C3. It used all-wheel drive with a 3.73 final drive gear ratio and included the 6.0 L "Vortec 6000" LQ4 V8 rated at at 5000 rpm and 370 lb•ft (502 N·m) of torque at 4000 rpm coupled to a 4L60E-HD four-speed automatic transmission along with other upscale equipment. For 2002, the name was changed to Sierra Denali, but the specifications remained essentially the same except for the addition of Quadrasteer and GM changed from the 4L60E-HD to the 4L65E in conjunction with a 4.10 final drive gear ratio.
