Miles Overview

The Sierra 3500 is GMC's heavy-duty pickup, built to tow and haul with serious capability across its trim range. It competes head-to-head with the Ford F-350 Super Duty and Ram 3500 in the heavy-duty truck segment. The Sierra 3500 drives with the commanding presence you expect from a heavy-duty truck, and the diesel provides strong low-end grunt for towing. Cabin space is generous, with available luxury trims like Denali adding upscale materials and tech features. The SLT adds leather seating, a larger infotainment screen, and power-adjustable pedals over the SLE, without stepping up to the Denali's chrome and luxury price. It pairs a 6.6L I8 gasoline engine with an automatic transmission and four-wheel drive, delivering strong acceleration for daily driving and confident towing. Look for the SLT Premium Package, which adds heated and ventilated front seats, a heated steering wheel, and a 15-inch head-up display.
