BMW X1 vs Genesis G90: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW X1 burns about $2,700 of fuel annually against $3,600 for the Genesis G90. 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 BMW X1 leads in both cycles — 25 mpg city and 34 mpg highway against 18 and 26 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW X1 is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI), the Genesis G90 with 3 (SIDI & PFI, SIDI & PFI; Mild Hybrid, SIDI). Across 23 recorded BMW X1 configurations and 32 for the Genesis G90, 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 BMW X1 is offered with All-Wheel Drive, Front-Wheel Drive, Rear-Wheel Drive, the Genesis G90 with All-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 Large Cars and Large Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the BMW X1 emits 311 g/mile of CO2 versus 426 g/mile for the Genesis G90. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
