The Vortec 5.3L V8 engine with Active Fuel Management delivers 300 hp at 5200 rpm, and 321 lb.-ft. of torque at 4000 rpm.
When driving conditions require less power, the Active Fuel Management system temporarily allows the 5.3L V8 engine to shift automatically from eight cylinders to four, resulting in impressive fuel economy gains.
When you engage the automatic 4WD mode, the system detects wheel slippage and automatically transfers torque to the front wheels for enhanced traction and then returns to two-wheel drive as conditions warrant. You may also choose to engage 4WD on a full-time basis.
