2026 GMC Sierra 1500 AT4 CREWCAB AWD DURAMAX TURBO DIESEL 3.0L LEATHER FOOTBOARD 

in Laval 

This pre-owned 2026 GMC Sierra 1500 AT4 Crew Cab AWD is now available at Olivier Mazda de Laval in Laval, with 14,447 km on the odometer and powered by a 3.0L Duramax turbodiesel engine. Built as a full-size half-ton truck with serious capability, this Sierra AT4 comes in Summit White and checks every box for buyers who need a truck that works as hard as it looks.

The Sierra 1500 sits firmly in the premium half-ton segment, competing with the Ram 1500 and Ford F-150, and the AT4 trim adds off-road-ready credentials with standard four-wheel drive and lifted hardware straight from the factory. GMC trucks consistently hold their value well, making this a smart long-term ownership decision for contractors, outdoor enthusiasts, or anyone who needs genuine towing and payload capacity day to day. This particular example is equipped with leather seating, heated front seats, and factory running boards, keeping occupant comfort high whether on the highway or heading off the beaten path. The 3.0L Duramax diesel is one of the most fuel-efficient powerplants available in a half-ton pickup, delivering strong torque without frequent fuel stops.
