Land Rover Range Rover vs Lexus RX: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lexus RX burns about $2,100 of fuel annually against $2,850 for the Land Rover Range Rover. That $750 yearly gap compounds to roughly $3,750 over five years and $6,000 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 Lexus RX leads in both cycles — 37 mpg city and 34 mpg highway against 26 and 30 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Land Rover Range Rover is recorded with 4 distinct engine configurations (SIDI; Mild Hybrid, SIDI, SIDI; PHEV), the Lexus RX with 4 (SIDI & PFI, SIDI & PFI; Hybrid, SIDI & PFI; PHEV). Across 191 recorded Land Rover Range Rover configurations and 59 for the Lexus RX, 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 Land Rover Range Rover is offered with 4-Wheel Drive, All-Wheel Drive, the Lexus RX with Front-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 Sport Utility Vehicle 4WD and Small 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 Lexus RX emits 89 g/mile of CO2 versus 102 g/mile for the Land Rover Range Rover. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
