Genesis G70 vs Kia Stinger: 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 $3,050 for the Kia Stinger. That $0 yearly gap compounds to roughly $0 over five years and $0 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 Kia Stinger leads in both cycles — 22 mpg city and 32 mpg highway against 22 and 31 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 Kia Stinger with 2 (SIDI, SIDI & PFI). Across 35 recorded Genesis G70 configurations and 24 for the Kia Stinger, 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 Kia Stinger 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 Midsize 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 Kia Stinger emits 355 g/mile of CO2 versus 357 g/mile for the Genesis G70. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
