Buick Enclave vs Honda Pilot: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Buick Enclave burns about $2,650 of fuel annually against $2,650 for the Honda Pilot. That $0 yearly gap compounds to roughly $0 over five years and $0 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 Honda Pilot leads in both cycles — 20 mpg city and 27 mpg highway against 20 and 27 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Buick Enclave is recorded with 1 distinct engine configuration (SIDI), the Honda Pilot with 2 (SIDI, 3.5). Across 26 recorded Buick Enclave configurations and 43 for the Honda Pilot, 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 Buick Enclave is offered with All-Wheel Drive, Front-Wheel Drive, the Honda Pilot 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 Small 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 Buick Enclave emits 387 g/mile of CO2 versus 388 g/mile for the Honda Pilot. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
