It starts with the world-class EcoTec3 5.3L V8, an all-new engine designed to generate more power and offer better fuel economy than any large SUV of any competitor in the industry – an EPA-estimated 10.2 L/100km – without sacrificing performance. The strong, efficient EcoTec3 V8 generates 355 horsepower and 519 Nm of torque, giving you the confidence to handle just about any driving situation.
Direct Injection determines the precise measure of highly pressurized fuel to inject into each cylinder to boost power and fuel efficiency while reducing emissions.
At cruising speeds when full engine power isn’t needed, Active Fuel Management™ deactivates cylinders, effectively turning the EcoTec3 V8 engine into a 4-cylinder. When it senses the need for full power, AFM instantly reengages all cylinders.
Variable Valve Timing helps ensure Tahoe performs at optimum power and efficiency. It continuously adjusts valve timing to keep the EcoTec3 engine operating near peak output, while minimizing emissions.
