Fuel Economy Overview

The 2004 Audi A8 L achieves an EPA-estimated 18 MPG in combined city and highway driving, with 16 MPG in the city and 22 MPG on the highway. Powered by a 4.2L 8-cylinder engine paired with a automatic (s6), this large cars features 4-Wheel or All-Wheel Drive drive.

In terms of environmental impact, the 2004 A8 L produces approximately 494 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this A8 L has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,850, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $8,500 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.

Aerodynamic Speed Penalty

EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.
