Maserati Grecale vs Rivian R1S: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Rivian R1S burns about $900 of fuel annually against $950 for the Maserati Grecale. 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 versus highway split: the Rivian R1S is the stronger commuter at 94 mpg city, while the Maserati Grecale pulls ahead on the interstate at 78 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 Grecale is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI; Mild Hybrid), the Rivian R1S with no. Across 16 recorded Maserati Grecale configurations and 94 for the Rivian R1S, 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 Grecale is offered with All-Wheel Drive, the Rivian R1S with 4-Wheel Drive, Part-time 4-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 Small Sport Utility Vehicle 4WD and Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
