Chevrolet Suburban vs Land Rover Defender: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Suburban burns about $3,250 of fuel annually against $3,800 for the Land Rover Defender. That $550 yearly gap compounds to roughly $2,750 over five years and $4,400 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 Suburban leads in both cycles — 21 mpg city and 27 mpg highway against 18 and 23 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Suburban is recorded with 4 distinct engine configurations (3.0, SIDI, SIDI; Stop-Start), the Land Rover Defender with 2 (SIDI; Mild Hybrid, SIDI). Across 72 recorded Chevrolet Suburban configurations and 54 for the Land Rover Defender, 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 Suburban is offered with 4-Wheel Drive, Rear-Wheel Drive, the Land Rover Defender with 4-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 Sport Utility Vehicle 4WD and Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Chevrolet Suburban emits 437 g/mile of CO2 versus 444 g/mile for the Land Rover Defender. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
