GMC Acadia vs Kia Telluride: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Kia Telluride burns about $1,750 of fuel annually against $2,450 for the GMC Acadia. That $700 yearly gap compounds to roughly $3,500 over five years and $5,600 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 Kia Telluride leads in both cycles — 34 mpg city and 36 mpg highway against 22 and 29 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the GMC Acadia is recorded with 1 distinct engine configuration (SIDI), the Kia Telluride with 3 (SIDI & PFI, SIDI; Hybrid, SIDI). Across 44 recorded GMC Acadia configurations and 18 for the Kia Telluride, 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 GMC Acadia is offered with All-Wheel Drive, Front-Wheel Drive, the Kia Telluride 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 2WD 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 Kia Telluride emits 251 g/mile of CO2 versus 349 g/mile for the GMC Acadia. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
