Maserati Grancabrio vs Porsche Taycan: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Porsche Taycan burns about $800 of fuel annually against $900 for the Maserati Grancabrio. 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 and highway economy: the Porsche Taycan leads in both cycles — 94 mpg city and 92 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 Maserati Grancabrio is recorded with 1 distinct engine configuration (SIDI & PFI), the Porsche Taycan with no. Across 9 recorded Maserati Grancabrio configurations and 84 for the Porsche Taycan, 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 Grancabrio is offered with All-Wheel Drive, the Porsche Taycan 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 Subcompact Cars and Compact Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
