Audi A8 vs MINI John Cooper Works: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the MINI John Cooper Works burns about $2,550 of fuel annually against $2,850 for the Audi A8. That $300 yearly gap compounds to roughly $1,500 over five years and $2,400 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 MINI John Cooper Works leads in both cycles — 27 mpg city and 37 mpg highway against 24 and 36 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Audi A8 is recorded with 4 distinct engine configurations (SIDI; Mild Hybrid, SIDI; PHEV, SIDI), the MINI John Cooper Works with 2 (SIDI & PFI, SIDI). Across 28 recorded Audi A8 configurations and 56 for the MINI John Cooper Works, 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 A8 is offered with All-Wheel Drive, 4-Wheel Drive, the MINI John Cooper Works with Front-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 Large Cars and Subcompact 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 A8 emits 213 g/mile of CO2 versus 288 g/mile for the MINI John Cooper Works. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
