The 2014 Chevrolet Silverado 1500 and the GMC Sierra 1500, available this fall with a 6.2L V8 produce an SAE-certified 420 hp (at 5600 rpm) and 460 lb.-ft. of torque (at 4100 rpm), the most power of any pickup engine and torque of any light duty pickup truck engine.
The 6.2L V8 available for Silverado LTZ and High Country and Sierra SLT and Denali models also delivers class-leading maximum available trailering capacity of 12,000 lb. when properly equipped.
“Power and towing capacity are fundamental capabilities for full-size pickups,” said Jeff Luke, General Motors executive chief engineer for full- and mid-size trucks. “The 2014 Silverado and Sierra deliver unmatched power and towing capability with a host of ingenious driver aids.”
The optional Max Trailering Package available on 2WD and 4WD V8 crew cab and double cab models includes:
- Trailering package with seven-pin and four-pin connector
- Enhanced cooling
- Automatic locking rear differential
- Heavy-duty 9.75-in. rear axle with 3.73 ratio
- Increased-capacity rear leaf springs
- Revised shock tuning for increased control
- Integrated trailer brake controller
Silverado 1500 and Sierra 1500 will also offer a 4.3L V6 SAE-certified at 285 hp and 305 lb.-ft. of torque and a 5.3L V8 certified at 355 hp and 383 lb.-ft. of torque.
Silverado and Sierra trucks equipped with the 4.3L V6 will have available towing ratings of up to 7,600 lb., the highest for any base V6 in the segment. Silverado and Sierra trucks equipped with the 5.3L V8 and the max towing package, available later this year, will have towing ratings of up to 11,500 lb. when properly equipped.
All three engines feature a unique combination of direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing. The engines also use a compact overhead-valve design and weight-saving components such as aluminum blocks and cylinder heads to reduce mass for additional energy savings.
All three provide the proven power, torque and dependability of a large-displacement engine, seamlessly switching to four-cylinder mode to save fuel during light-load driving. The 5.3L V8 has EPA-estimated fuel economy of up to 23 mpg highway (2WD models), the best of any V8 pickup, and better than Ford EcoBoost V6.
EPA fuel economy estimates for the 6.2L V8 will be finalized in the near future.
