GMC is upgrading its heavy-duty Sierra pickup trucks for the 2024 model year, with bold styling, potent powertrains, added comfort and convenience, and more standard safety features.
The base engine is a 401-hp, 6.6-liter V8 with a 10-speed automatic transmission.
For large towing chores, there is an available turbodiesel V8, plus a variety of assistance features, such as special cameras, adaptive cruise control, blind spot warning, and a maximum weight monitor.
The trims walk from basic, work-focused Pro up to the AT4X off-road champ and Denali Ultimate, a new, full-featured, leather-lined version.
Standard active safety features include FCW, AEB with pedestrian detection, and LDW.
