Maserati Granturismo vs Rolls-Royce Spectre: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Maserati Granturismo burns about $850 of fuel annually against $950 for the Rolls-Royce Spectre. 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 versus highway split: the Maserati Granturismo is the stronger commuter at 90 mpg city, while the Rolls-Royce Spectre pulls ahead on the interstate at 86 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.

Powertrain choice: the Maserati Granturismo is recorded with 2 distinct engine configurations (SIDI & PFI, 4.7), the Rolls-Royce Spectre with no. Across 18 recorded Maserati Granturismo configurations and 12 for the Rolls-Royce Spectre, 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 Granturismo is offered with All-Wheel Drive, Rear-Wheel Drive, the Rolls-Royce Spectre with 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 Subcompact Cars and Compact Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
