Lincoln Aviator vs Toyota Grand Highlander: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota Grand Highlander burns about $1,700 of fuel annually against $2,650 for the Lincoln Aviator. That $950 yearly gap compounds to roughly $4,750 over five years and $7,600 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 Toyota Grand Highlander leads in both cycles — 37 mpg city and 34 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 Lincoln Aviator is recorded with 4 distinct engine configurations (SIDI, 3.0, SIDI; without Stop-Start), the Toyota Grand Highlander with 2 (SIDI & PFI, SIDI & PFI; Hybrid). Across 19 recorded Lincoln Aviator configurations and 22 for the Toyota Grand Highlander, 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 Lincoln Aviator is offered with Rear-Wheel Drive, Part-time 4-Wheel Drive, the Toyota Grand Highlander with 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 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 Lincoln Aviator emits 209 g/mile of CO2 versus 246 g/mile for the Toyota Grand Highlander. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
