Audi Q6 e-tron vs Volvo XC40: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Volvo XC40 burns about $700 of fuel annually against $750 for the Audi Q6 e-tron. That $50 yearly gap compounds to roughly $250 over five years and $400 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 versus highway split: the Volvo XC40 is the stronger commuter at 118 mpg city, while the Audi Q6 e-tron pulls ahead on the interstate at 97 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.

Powertrain choice: the Audi Q6 e-tron is recorded with no distinct engine configurations, the Volvo XC40 with 2 (SIDI; Mild Hybrid, SIDI). Across 11 recorded Audi Q6 e-tron configurations and 19 for the Volvo XC40, 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 Q6 e-tron is offered with All-Wheel Drive, Rear-Wheel Drive, the Volvo XC40 with All-Wheel Drive, Front-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 Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
