Hyundai Santa Cruz vs Infiniti QX80: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Hyundai Santa Cruz burns about $2,450 of fuel annually against $4,200 for the Infiniti QX80. That $1,750 yearly gap compounds to roughly $8,750 over five years and $14,000 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 Hyundai Santa Cruz leads in both cycles — 22 mpg city and 30 mpg highway against 16 and 20 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Hyundai Santa Cruz is recorded with 1 distinct engine configuration (SIDI & PFI), the Infiniti QX80 with 4 (SIDI, SIDI; MDPV, SIDI; MDPV (Curb Weight >6000 lbs)). Across 20 recorded Hyundai Santa Cruz configurations and 30 for the Infiniti QX80, 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 Hyundai Santa Cruz is offered with All-Wheel Drive, Front-Wheel Drive, the Infiniti QX80 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 Hyundai Santa Cruz emits 356 g/mile of CO2 versus 504 g/mile for the Infiniti QX80. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
