Lexus TX vs Lincoln Nautilus: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lincoln Nautilus burns about $2,050 of fuel annually against $2,600 for the Lexus TX. 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 Lincoln Nautilus leads in both cycles — 30 mpg city and 31 mpg highway against 29 and 28 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 Nautilus with 3 (SIDI & PFI; Hybrid, SIDI & PFI, SIDI). Across 10 recorded Lexus TX configurations and 28 for the Lincoln Nautilus, 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 Nautilus with Part-time 4-Wheel Drive, All-Wheel Drive, Front-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 TX emits 120 g/mile of CO2 versus 290 g/mile for the Lincoln Nautilus. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
