BMW iX vs Porsche Macan: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Porsche Macan burns about $700 of fuel annually against $800 for the BMW iX. 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 Porsche Macan leads in both cycles — 114 mpg city and 96 mpg highway against 99 and 94 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW iX is recorded with no distinct engine configurations, the Porsche Macan with 1 (SIDI). Across 35 recorded BMW iX configurations and 56 for the Porsche Macan, 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 iX is offered with All-Wheel Drive, the Porsche Macan 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 Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
