The 2020 Bugatti Chiron emits approximately 840 grams of CO₂ per mile at the tailpipe, earning an EPA greenhouse-gas score of 1 out of 10. Lower emissions generally track higher fuel economy.
How to read these numbers
EPA figures come from standardized laboratory test cycles and are the same estimates shown on the vehicle's window sticker. Your real-world mileage depends on driving style, conditions, fuel grade, and maintenance. Use combined MPG and annual fuel cost to compare vehicles fairly.
