Lexus TX vs Lincoln Aviator: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lexus TX burns about $2,600 of fuel annually against $2,650 for the Lincoln Aviator. That $50 yearly gap compounds to roughly $250 over five years and $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 Lexus TX leads in both cycles — 29 mpg city and 28 mpg highway against 22 and 26 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Lexus TX is recorded with 3 distinct engine configurations (SIDI & PFI, SIDI & PFI; Hybrid, SIDI & PFI; PHEV), the Lincoln Aviator with 4 (SIDI, 3.0, SIDI; without Stop-Start). Across 10 recorded Lexus TX configurations and 19 for the Lincoln Aviator, 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 Lexus TX is offered with All-Wheel Drive, Front-Wheel Drive, the Lincoln Aviator with Rear-Wheel Drive, Part-time 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 Lexus TX emits 120 g/mile of CO2 versus 209 g/mile for the Lincoln Aviator. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
