Audi Q4 e-tron vs Kia EV9: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Audi Q4 e-tron burns about $650 of fuel annually against $850 for the Kia EV9. That $200 yearly gap compounds to roughly $1,000 over five years and $1,600 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 Q4 e-tron leads in both cycles — 125 mpg city and 104 mpg highway against 101 and 78 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Drivetrain and class: the Audi Q4 e-tron is offered with All-Wheel Drive, Rear-Wheel Drive, the Kia EV9 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 Standard Sport Utility Vehicle 4WD and Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
