Fuel Economy Overview

The 2003 Audi A6 Avant quattro achieves an EPA-estimated 19 MPG in combined city and highway driving, with 16 MPG in the city and 24 MPG on the highway. Powered by a 3L 6-cylinder engine paired with a automatic (s5), this midsize station wagons features 4-Wheel or All-Wheel Drive drive.

In terms of environmental impact, the 2003 A6 Avant quattro produces approximately 468 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 A6 Avant quattro has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,650, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $7,500 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.

VOLKSWAGEN IS RECALLING CERTAIN MODEL YEAR 2001-2004 AUDI A6, MODEL YEAR 2002-2003 S6 AND MODEL YEAR 2003 RS6 VEHICLES EQUIPPED WITH 4.2L ENGINES AND MANUFACTURED FROM JUNE 19, 2001, THROUGH JUNE 8, 2004. THE AGING OF THE PLASTIC MATERIAL IN THE FUEL TANK ROLLOVER VALVE COMBINED WITH BENDING STRESS FROM THE ALUMINUM VENTILATION LINE TO THE ROLLOVER VALVE NIPPLE MAY LEAD TO CRACKING OF THE NIPPLE. IF THIS HAPPENS, A FUEL LEAK MAY RESULT.

Consequence & Remedy

Consequence: A FUEL LEAK IN THE PRESENCE OF AN IGNITION SOURCE COULD LEAD TO A VEHICLE FIRE.

Remedy: DEALERS WILL REINFORCE THE NIPPLE ON THE ROLLOVER VALVE TO PREVENT LEAKAGE OR REPAIR THE CRACKING AT THE NIPPLE. THE RECALL IS EXPECTED TO BEGIN DURING JUNE 2011. OWNERS MAY CONTACT AUDI AT 1-800-822-2834.
