GMC Expands Capability of 2024 Sierra 1500 AT4X
The Duramax engine delivers increased power and torque and was first introduced on select 2023 Sierra 1500 trims. GMC has taken this Duramax engine and advanced it. The 2.0L Duramax engine will be standard with a 10 speed automatic transmission and deliver 305 horse power with a max torque of 495 lb-ft!
“These refinements of the 3.0L Duramax Turbo-Diesel engine took an already awesome engine and made it even better for off-road applications.” “The outstanding low-end torque combined with the smooth and quiet power of this diesel engine, make it ideal for customers requiring on-road capability for things like towing, as well as off-road adventures like long-distance overlanding.”(John Barta, GM Assistant Chief Engineer, Diesel Engines)
