2018 GMC Sierra 2500 Heavy Duty - Trucks Reviews 2017 2018

The 2018 GMC Sierra 2500 Heavy Duty comes as a mid-cycle refresh of a full-size pickup, which got a second life back in 2015 with the introduction of the restyled Sierra and Chevrolet Silverado.
The model features a choice of two engines, two automatic transmission, an updated exterior look and a more comfortable and technology-packed interior carried over from the 2015 Sierra 1500.

Exterior and Interior

2018 GMC Sierra 2500 Heavy Duty side and front

The 2018 GMC Sierra 2500 Heavy Duty features a new Double Cab configuration, which includes longer, front-hinged rear doors with outside pull handles at the rear and new structural B-pillars.
Also, the model sits on 18-inch alloy wheels and features tall athletic lines and clean departure angles. Moreover, the Sierra’s new grille is much larger, as it sweeps down into the revised bumper.

The profile presents more chiseled lines with chrome running boards alongside the flanks, in addition to chrome door trim and chrome-tipped towing mirrors.

Round back, a chrome rear bumper and corporate badging are standard, while the side mirrors include backup lights. These are twin LED lights which illuminate the area between the front windows and the tailgate.

At first glance the 2018 GMC Sierra looks basically the same as in the outgoing model, but there are changes and they come in way of upgraded and more plush materials, restyled gauges and new door seal plates.

The cabin comes with standard 4G LTE connectivity with Wi-Fi tethering, plus GMC’s IntelliLink infotainment system featuring navigation, voice recognition, and Bluetooth connectivity. There are also available five USB ports, a 110-volt standard house receptacle, and at least three 12-volt plugs.

The instrument panel looks and feels more functional and cleaner than the last time thanks to a brand new instrument cluster including six gauges with an available centrally located, 4.2-inch-diagonal color driver information center.
