Audi A7 vs Genesis G70: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Audi A7 burns about $2,600 of fuel annually against $3,050 for the Genesis G70. That $450 yearly gap compounds to roughly $2,250 over five years and $3,600 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 Audi A7 leads in both cycles — 26 mpg city and 38 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 Audi A7 is recorded with 4 distinct engine configurations (SIDI; Mild Hybrid, SIDI; PHEV, SIDI), the Genesis G70 with 2 (SIDI & PFI, SIDI). Across 15 recorded Audi A7 configurations and 35 for the Genesis G70, 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 Audi A7 is offered with All-Wheel Drive, 4-Wheel Drive, the Genesis G70 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 Midsize Cars and Compact 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 Audi A7 emits 126 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.
