Cadillac XT4 vs Toyota Sequoia: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota Sequoia burns about $2,800 of fuel annually against $2,900 for the Cadillac XT4. That $100 yearly gap compounds to roughly $500 over five years and $800 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 Cadillac XT4 leads in both cycles — 24 mpg city and 30 mpg highway against 21 and 24 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Cadillac XT4 is recorded with 1 distinct engine configuration (SIDI), the Toyota Sequoia with 3 (SIDI & PFI; Hybrid, 5.7, FFV). Across 14 recorded Cadillac XT4 configurations and 30 for the Toyota Sequoia, 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 Cadillac XT4 is offered with All-Wheel Drive, Front-Wheel Drive, the Toyota Sequoia with Rear-Wheel Drive, Part-time 4-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 Cadillac XT4 emits 336 g/mile of CO2 versus 395 g/mile for the Toyota Sequoia. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
