Genesis G70 vs Maserati Quattroporte: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Genesis G70 burns about $3,050 of fuel annually against $3,800 for the Maserati Quattroporte. That $750 yearly gap compounds to roughly $3,750 over five years and $6,000 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 Genesis G70 leads in both cycles — 22 mpg city and 31 mpg highway against 17 and 25 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Genesis G70 is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI), the Maserati Quattroporte with 1 (SIDI). Across 35 recorded Genesis G70 configurations and 32 for the Maserati Quattroporte, 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 G70 is offered with Rear-Wheel Drive, All-Wheel Drive, the Maserati Quattroporte with Rear-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 Compact 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 Genesis G70 emits 357 g/mile of CO2 versus 453 g/mile for the Maserati Quattroporte. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
