The 2021 GMC Sierra 1500 combines raw power, modern luxury and cutting-edge digital technology into a single impressive platform. Buick GMC Fort Walton Beach offers this light-duty pickup truck with three cabin configurations. The well-appointed Denali model has the most luxurious amenities from our inventory. Imported from Japan, the 2021 Toyota Tundra truck also offers several cab options.


The 2021 GMC Sierra 1500 gets up to 420 horsepower from a 6.2 L engine block with a V8 design. Built on the EcoTec3 architecture, the eight-cylinder powerplant unleashes 460 pound-feet of torque. If necessary, the Dynamic Fuel Management disengages up to six cylinders for optimal efficiency. The DFM can operate on 17 unique cycles depending on the driving conditions. The 2021 GMC Sierra 1500 at Buick GMC Fort Walton Beach is also sold with a turbo-diesel powertrain that carries the proven Duramax design. This 3.0 L propulsion system matches the torque output of the 6.2 L gasoline engine. When paired with the Max Trailering Package, this eight-cylinder engine supports a maximum conventional hitch load of 11,800 pounds. By contrast, the 2021 Toyota Tundra is not strong enough to tow a trailer that’s packed with more than 10,200 pounds. Under the hood, this imported pickup truck has a 5.7 L gas engine that has output limits of 381 hp and 401 lb-ft. However, the i-FORCE V8 powerplant has the VVT-i and other features that improve efficiency on the road. A test drive of the 2021 GMC Sierra 1500 reveals other mechanical options on the lineup, such as the 4.3 L V6 and 5.3 L V8 engines. Both gas engines run on the EcoTec3 and Active Fuel Management technologies.


As a legendary pickup truck, the 2021 GMC Sierra 1500 at Buick GMC Fort Walton Beach offers a 4×4 drive system. A locking rear differential with the Eaton Locker is installed on this light-duty model.

The Terrain Mode is only available on models that have a single-speed transfer case. The Snow Mode is available on trims that roll on a 2WD system. Other modes from the TSS include the Tour, Sport, Off-Road and Tow/Haul.
