2026 GMC Sierra 3500 Overview

The 2026 GMC Sierra 3500, part of the fifth generation, is a robust and capable heavy-duty truck that perfectly combines luxurious comfort with off-road durability. It comes in four trims: the SLT, Denali, AT4, and base Sierra. Depending on the chosen model, you can opt for a 6.6L V8 gas engine delivering 401 hp, or a potent 6.6L Duramax Diesel V8 with 445 hp. With a 10-speed automatic transmission and Rear-wheel drive (4-wheel drive optional), the Sierra is built for tough tasks. Tech highlights include an infotainment system with a 7-inch or upgradable 8-inch touchscreen, Apple CarPlay and Android Auto, and a Wi-Fi hotspot. For safety, it offers advanced features like lane departure warning and forward collision alert. Its introduction for 2026 is yet to be fully realized, but the Sierra 3500 is expected to continue GMC’s reputation for durability and power.
