Audi A6 vs Chevrolet Malibu: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Malibu burns about $1,350 of fuel annually against $2,650 for the Audi A6. That $1,300 yearly gap compounds to roughly $6,500 over five years and $10,400 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 and highway economy: the Chevrolet Malibu leads in both cycles — 49 mpg city and 46 mpg highway against 25 and 38 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Audi A6 is recorded with 3 distinct engine configurations (SIDI, SIDI; Mild Hybrid, 3.0), the Chevrolet Malibu with 2 (SIDI, SIDI; Hybrid). Across 36 recorded Audi A6 configurations and 24 for the Chevrolet Malibu, 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 A6 is offered with All-Wheel Drive, 4-Wheel Drive, Front-Wheel Drive, the Chevrolet Malibu with Front-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 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 Chevrolet Malibu emits 194 g/mile of CO2 versus 311 g/mile for the Audi A6. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
