Fuel Economy

EPA estimates by engine (2WD; four-wheel-drive and off-road trims rate a few MPG lower):

The 6.2L V8 trades efficiency for output and is the least fuel-efficient of the gas engines; check the window sticker for the EPA estimate on a specific build. The diesel's 28 MPG highway is the efficiency leader of the group.

Safety and Technology

Chevy Safety Assist is standard on every Silverado 1500 trim and bundles six driver aids: Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, a Following Distance Indicator, and IntelliBeam automatic high beams.

Trim-Level Spec Differences

The work-focused WT and Custom run the 2.7L TurboMax with the smaller screen and steel or alloy wheels. The LT and RST add the larger displays and V8 availability. The Custom Trail Boss and LT Trail Boss bring a 2-inch factory lift, Z71 suspension, and all-terrain tires. The LTZ and High Country make the 5.3L V8 standard and layer in leather and premium tech, while the ZR2 is the off-road flagship with the Duramax or 6.2L V8, DSSV dampers, lockers, and 33-inch tires. The full equipment-by-trim breakdown lives on the all-trims comparison; shoppers cross-shopping the heavy-duty truck can also see the Silverado 1500 vs 2500HD comparison.
