Buick Envision vs GMC Yukon: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Buick Envision burns about $2,350 of fuel annually against $3,250 for the GMC Yukon. That $900 yearly gap compounds to roughly $4,500 over five years and $7,200 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 Buick Envision leads in both cycles — 24 mpg city and 31 mpg highway against 21 and 27 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Buick Envision is recorded with 1 distinct engine configuration (SIDI), the GMC Yukon with 4 (3.0, SIDI, SIDI; Stop-Start). Across 22 recorded Buick Envision configurations and 164 for the GMC Yukon, 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 Envision is offered with All-Wheel Drive, Front-Wheel Drive, the GMC Yukon with 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 Small 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 Buick Envision emits 337 g/mile of CO2 versus 437 g/mile for the GMC Yukon. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
