Key Features and Specifications

The versatile and powerful GMC Sierra HD sets the standard for heavy-duty pickups. We’ve provided a rundown of exactly why it might be the perfect truck to meet your needs.

Engine Performance and Towing Capacity

The standard GMC Sierra HD powertrain is a lively 6.6-liter V-8 gas engine paired with a 10-speed Allison automatic transmission. The result is a formidable 401 hp and 464 lb-ft of torque. But for truly heavy-duty output, GMC offers an available 6.6-liter Duramax Turbo-Diesel V-8 engine that delivers a staggering 470 hp and 975 lb-ft of torque.

It’s this Duramax powertrain that produces the Sierra HD’s incredible towing performance. A rear-wheel-drive GMC Sierra 3500 HD Regular Cab long bed, properly equipped, boasts an astounding maximum towing capacity of 36,000 pounds.

Cutting-Edge Technology and Infotainment

A fully connected GMC infotainment system provides ultimate enjoyment for all passengers. Apple CarPlay and Android Auto compatibility allow you to sync your devices and enjoy your favorite music. You can even access your favorite apps through the available 13.4-inch diagonal center touch screen, which comes standard on higher trims.

Also available is an innovative 15-inch multicolor head-up display. This advanced technology projects important vehicle data directly onto the windscreen in the driver’s line of sight. This allows you to stay updated with key information, such as speed and any vehicle alerts, without taking your eyes off the road ahead.

Safety and Driver-Assistance Systems

Every GMC Sierra HD truck comes equipped with a comprehensive suite of safety and driver-assistance technologies. StabiliTrak — an electronic stability control system with traction control — adjusts the brakes and engine torque to provide enhanced control, particularly during emergency maneuvers. Traction control applies brake pressure and/or reduces engine power to help you keep control of the vehicle when the system detects wheel slippage.

Other standard safety features include:

• Automatic emergency braking
• Lane departure warning
• Forward collision alert
• Front pedestrian braking
• IntelliBeam headlamps
