2024 GMC Sierra HD Pickup Overview
The Sierra HD will be offered in Regular Cab, Extended Cab and Crew Cab body styles, with a choice of two bed lengths, rear-wheel drive and four-wheel drive, and two powertrains: gasoline and diesel.
The 6.6-liter gasoline V8 returns, but a 10-speed automatic transmission replaces the previous six-speed. The turbodiesel V8 gains more power, with 470 hp and a hearty 975 lb-ft. of torque. When equipped with the optional turbodiesel and a two-rear-wheel setup, the two-wheel-drive GMC Sierra 3500HD can tow a whopping 36,000 pounds.
Sierra HD trucks come with a standard suite of active safety systems, including automatic emergency braking with pedestrian detection, an especially welcome feature, given the height of the massive hood.
Available trims include Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate.
The Sierra HD will go on sale in early 2023, followed by the AT4X later in the year.
