Chevrolet Silverado vs Rivian R1T: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Rivian R1T burns about $850 of fuel annually against $1,100 for the Chevrolet Silverado. That $250 yearly gap compounds to roughly $1,250 over five years and $2,000 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 Rivian R1T leads in both cycles — 94 mpg city and 80 mpg highway against 78 and 63 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 Rivian R1T with no. Across 300 recorded Chevrolet Silverado configurations and 91 for the Rivian R1T, 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 Rivian R1T with 4-Wheel Drive, Part-time 4-Wheel Drive, 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.
