Two gasoline engines and a diesel option power the 2021 Tahoe lineup. Chevrolet's 5.3-liter EcoTec3 V-8 engine with Dynamic Fuel Management uses direct-injection and variable valve timing technology. Paired with a 10-speed automatic transmission, this powertrain supplies 355 horsepower and 383 pound-feet of torque.
Next up is the 6.2-liter V-8 engine, also with Dynamic Fuel Management, variable valve timing, and direct-injection technology. This powertrain, mated to the same 10-speed automatic transmission, supplies an impressive 420 horsepower and 460 pound-feet of torque.
Lastly, the Duramax 3.0-liter turbo-diesel motor provides the perfect blend of power and efficiency, combing with a 10-speed transmission to produce 277 horsepower and 460 pound-feet of torque.
