BMW 4 Series vs Maserati Ghibli: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW 4 Series burns about $2,450 of fuel annually against $3,800 for the Maserati Ghibli. That $1,350 yearly gap compounds to roughly $6,750 over five years and $10,800 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 BMW 4 Series leads in both cycles — 28 mpg city and 36 mpg highway against 18 and 25 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW 4 Series is recorded with 4 distinct engine configurations (SIDI & PFI; Mild Hybrid, SIDI, SIDI; Mild Hybrid), the Maserati Ghibli with 1 (SIDI). Across 160 recorded BMW 4 Series configurations and 33 for the Maserati Ghibli, 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 4 Series is offered with Rear-Wheel Drive, All-Wheel Drive, the Maserati Ghibli with Rear-Wheel Drive, All-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 Compact Cars and Midsize 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 4 Series emits 285 g/mile of CO2 versus 436 g/mile for the Maserati Ghibli. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
