Genesis G80 vs Maserati Grancabrio: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Genesis G80 burns about $750 of fuel annually against $900 for the Maserati Grancabrio. That $150 yearly gap compounds to roughly $750 over five years and $1,200 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 Genesis G80 leads in both cycles — 105 mpg city and 93 mpg highway against 84 and 82 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Genesis G80 is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI), the Maserati Grancabrio with 1 (SIDI & PFI). Across 43 recorded Genesis G80 configurations and 9 for the Maserati Grancabrio, 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 Genesis G80 is offered with All-Wheel Drive, Rear-Wheel Drive, the Maserati Grancabrio 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 Large Cars and Subcompact 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 Genesis G80 emits 345 g/mile of CO2 versus 430 g/mile for the Maserati Grancabrio. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
