Chevrolet Silverado vs GMC Hummer EV: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Silverado burns about $1,100 of fuel annually against $1,400 for the GMC Hummer EV. That $300 yearly gap compounds to roughly $1,500 over five years and $2,400 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City and highway economy: the Chevrolet Silverado leads in both cycles — 78 mpg city and 63 mpg highway against 59 and 48 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Silverado is recorded with 4 distinct engine configurations (SIDI, w/ Sport and Off Road Mode, 3.0), the GMC Hummer EV with no. Across 300 recorded Chevrolet Silverado configurations and 16 for the GMC Hummer EV, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Chevrolet Silverado is offered with 4-Wheel Drive, Rear-Wheel Drive, All-Wheel Drive, the GMC Hummer EV with All-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Standard Pickup Trucks 4WD and Standard Pickup Trucks 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
