Lexus LX vs Lincoln Navigator: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lincoln Navigator burns about $3,250 of fuel annually against $3,800 for the Lexus LX. 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 versus highway split: the Lexus LX is the stronger commuter at 19 mpg city, while the Lincoln Navigator pulls ahead on the interstate at 23 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.
Powertrain choice: the Lexus LX is recorded with 3 distinct engine configurations (SIDI & PFI; Hybrid, SIDI & PFI, 5.7), the Lincoln Navigator with 3 (SIDI & PFI, SIDI, SIDI; Stop-Start). Across 14 recorded Lexus LX configurations and 35 for the Lincoln Navigator, 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 LX is offered with All-Wheel Drive, 4-Wheel Drive, the Lincoln Navigator with Part-time 4-Wheel Drive, Rear-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 2WD 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 LX emits 439 g/mile of CO2 versus 462 g/mile for the Lincoln Navigator. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
