2024 GMC Sierra 1500

The Sierra is available with four engines. They include:

• Turbocharged 2.7-liter four-cylinder engine (310 hp, 430 lb-ft of torque)
• Turbocharged 3.0-liter inline-six diesel engine (305 hp, 495 lb-ft of torque)
• 5.3-liter V8 (355 hp, 383 lb-ft of torque)
• 6.2-liter V8 (420 hp, 460 lb-ft)

Not every engine is available in every trim or configuration. The four-cylinder and 5.3-liter V8 (with rear-wheel drive) come with an eight-speed automatic. There's a 10-speed automatic for the 5.3-liter V8 with four-wheel drive, the diesel six-cylinder and the top-dog 6.2-liter V8. Rear-wheel drive is standard for most trims, with 4WD widely available.
