1998 Audi A6 quattro
Fuel Economy Overview
The 1998 Audi A6 quattro achieves an EPA-estimated 18 MPG in combined city and highway driving, with 15 MPG in the city and 24 MPG on the highway. Powered by a 2.8L 6-cylinder engine paired with a automatic 5-spd, this midsize cars features 4-Wheel or All-Wheel Drive drive.
In terms of environmental impact, the 1998 A6 quattro 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 A6 quattro 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.

Personalized Commute CalculatorEPA defaults to 55% City / 45% Hwy
Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
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.

Recall Intelligence
Volkswagen Group of America, Inc. (VW) is recalling certain 2000-2001 TT Roadster, 2000 TT Coupe, 1999 Audi A8, 1998-2000 Audi A6, and 1999-2000 Audi A4 vehicles equipped with Non-Azide Driver air bag Inflators (NADI) that do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, possibly causing the air bag to deploy improperly in the event of a crash.
Consequence & Remedy
Consequence: In the event of a crash necessitating air bag deployment, the air bag may not properly protect the occupant, increasing the risk of serious injury or death.
Remedy: Dealers will replace the driver frontal air bag inflator with an alternative inflator when the parts become available, free of charge. Owner notifications were mailed September 21, 2021. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69BT.

ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 2.8L, V6 5-VALVE ENGINES, AND AUTOMATIC TRANSMISSIONS, WHILE DRIVING DURING EXTREMELY LOW AMBIENT TEMPERATURES THE THROTTLE MAY FREEZE IN AN OPEN POSITION DUE TO ICE ACCUMULATING IN THE THROTTLE BODY.
Consequence & Remedy
Consequence: IF THIS OCCURS, THE VEHICLE MAY FAIL TO REDUCE SPEED WHEN THE DRIVER LIFTS HIS/HER FOOT FROM THE GAS PEDAL. THIS LOSS OF VEHICLE CONTROL COULD RESULT IN A CRASH WITHOUT WARNING.
Remedy: AUDI WILL INSTALL A REPLACEMENT THROTTLE BODY KIT FREE OF CHARGE. THE RECALL BEGAN ON OCTOBER 29, 2004. OWNERS MAY CONTACT AUDI AT 1-800-822-2834.

Consequence & Remedy
Consequence: A FIRE COULD ORIGINATE IN THE LEFT DASHBOARD AREA.
Remedy: DEALERS WILL INSTALL A PROTECTIVE COVERING ON THE KNEE BOLSTER (CRASH ELEMENT).

OWNERS SHOULD CONTACT AUDI AT 1-800-822-2834.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SULFUR IN FUEL INTERACTS WITH CERTAIN ADDITIVES FOUND IN WIDELY AVAILABLE GASOLINE CAUSING SULFUR TO BECOME DEPOSITED ON THE CONTACT POINTS OF THREE FUEL SENDING UNITS MOUNTED INSIDE THE FUEL TANK. THIS COULD CAUSE THE FUEL GAUGE TO READ FULL WHILE THE FUEL TANK MAY NOT IN FACT BE FULL OR COULD BE EMPTY.
Consequence & Remedy
Consequence: RUNNING OUT OF FUEL WITHOUT WARNING WHILE THE FUEL GAUGE INDICATES THAT THERE IS SUFFICIENT FUEL IN THE TANK LEAD TO SAFETY PROBLEMS.
Remedy: DEALERS WILL REMOVE THE EXISTING FUEL LEVEL SENDING UNITS AND REPLACE THEM WITH FUEL LEVEL SENDING UNITS USING A NEW ALLOY COMPOSED OF GOLD, SILVER, AND A SMALL AMOUNT OF NICKEL, WHICH WILL NOT CHEMICALLY REACT WITH SULFUR. VW/AUDI WILL ALSO CALL BACK VEHICLES THAT WERE REPAIRED UNDER A PREVIOUS RECALL LAST JUNE IN ORDER TO INSTALL THE UPDATED FUEL SENDING UNITS NHTSA 00V137/AUDI LB). OWNER NOTIFICATION BEGAN MAY 1, 2001.

Remedy: DEALERS WILL REPLACE THE TIE RODS.
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH QUATTRO DRIVE SYSTEM WHICH EMPLOYS A FUEL AND FUEL VAPOR LEAK DETECTION SYSTEM. IF THE VEHICLE IS REFUELED SHORTLY AFTER THE ENGINE IS STARTED, AND IS KEPT RUNNING WHILE BEING REFUELED, THE FUEL VAPOR RECOVERY SYSTEM COULD PRODUCE SUFFICIENT BACK PRESSURE TO CAUSE FUEL TO BE EJECTED AFTER A COMPLETE FILL-UP WHEN THE FUEL PUMP NOZZLE IS REMOVED FROM THE FILLER NECK.
Consequence & Remedy
Consequence: IN THE PRESENCE OF AN IGNITION SOURCE, FUEL SPRAY COULD RESULT IN FIRE OR POSSIBLE PERSONAL INJURY.
Remedy: VW IS PROVIDING A NEW PAGE FOR THE OWNER'S MANUAL AND ALSO REQUESTING OWNERS TO MAKE AN APPOINTMENT WITH THEIR DEALERS TO HAVE A LABEL CONTAINING IMPORTANT REFUELING INSTRUCTIONS INSTALLED INSIDE OF THE FUEL FILLER DOOR. DEALERS WILL ALSO REMOVE THE TIRE PRESSURE LABEL AND REPLACE IT WITH A NEW LABEL AFFIXED TO THE FENDER WELL AT THE RIGHT REAR DOOR.
