Maserati Ghibli vs Rolls-Royce Ghost: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Maserati Ghibli burns about $3,800 of fuel annually against $5,050 for the Rolls-Royce Ghost. That $1,250 yearly gap compounds to roughly $6,250 over five years and $10,000 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 Maserati Ghibli leads in both cycles — 18 mpg city and 25 mpg highway against 13 and 21 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Maserati Ghibli is recorded with 1 distinct engine configuration (SIDI), the Rolls-Royce Ghost with 1 (SIDI). Across 33 recorded Maserati Ghibli configurations and 33 for the Rolls-Royce Ghost, 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 Maserati Ghibli is offered with Rear-Wheel Drive, All-Wheel Drive, the Rolls-Royce Ghost 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 Midsize 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 Maserati Ghibli emits 436 g/mile of CO2 versus 580 g/mile for the Rolls-Royce Ghost. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
