GMC Previews Sierra HD
DETROIT – Led by the first-ever Sierra Heavy Duty Denali Ultimate, the 2024 model year takes the Sierra HD lineup to new heights with premium luxury and comfort, turbocharged pulling power and elevated technology — offering the most trailering assistance technology in its class1. In addition to the debut of the Denali Ultimate trim, the 2024 Sierra HD will build upon GMC’s premium off-road offerings, introducing the off-road optimized Sierra HD AT4X trim later in the model year.
