BMW i7 vs Maserati Granturismo: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW i7 burns about $800 of fuel annually against $850 for the Maserati Granturismo. That $50 yearly gap compounds to roughly $250 over five years and $400 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 i7 leads in both cycles — 91 mpg city and 95 mpg highway against 90 and 85 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW i7 is recorded with no distinct engine configurations, the Maserati Granturismo with 2 (SIDI & PFI, 4.7). Across 34 recorded BMW i7 configurations and 18 for the Maserati Granturismo, 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 i7 is offered with All-Wheel Drive, Rear-Wheel Drive, 4-Wheel Drive, the Maserati Granturismo 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 Subcompact Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
