Simply put, the A6 is a joy for both driver and passengers alike. Its potent supercharged V6 engine and slick eight-speed transmission deliver invigorating and effortless power. Available permanent Quattro all-wheel-drive assures traction and contributes to wintertime security. And yet at 22 mpg, fuel economy is quite commendable. But that's just the beginning.

Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit.
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.
Fuel Economy & Emissions
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Greenhouse Gas Greenhouse Gas The Greenhouse Gas Rating represents the amount of carbon dioxide the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).
Smog Rating Smog Rating The Smog Rating represents the amount of health-damaging and smog-forming airborne pollutants the vehicle emits compared to other vehicles of the same model year. This score from the EPA ranges from 1 (worst) to 10 (best).

Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Road Test

Simply put, the A6 is a joy for both driver and passengers alike. Its potent supercharged V6 engine and slick eight-speed transmission deliver invigorating and effortless power. Available permanent Quattro all-wheel-drive assures traction and contributes to wintertime security. And yet at 22 mpg, fuel economy is quite commendable. But that's just the beginning.

The A6 outperforms many of its peers because it is so multi-talented. It provides an uplifting driving experience thanks to its responsive steering and tied-down suspension. But it also rides smoothly, leaving the bumps and ruts of the road outside the solid, vault-like cabin. The interior is quiet, instilling a feeling of a safe-haven. Inside the A6 is sumptuous and accommodating, with super comfortable and supportive seats keeping you fresh and ache-free. The trunk is large and beautifully finished. Interior quality and ambience is top notch, although it's more businesslike than glitzy.

Cruise control

"The lane keep feature is nice but if the highway exit is at certain angle(?) to the main highway this lane keeping feature will try to follow the right white line off the highway. I force the car back to the highway at 70 MPH. Audi said it had no fix for this. Active Cruse control works great in traffic. Set the speed to about 30MPH it will go and stop in stop and go traffic with little help form me. Reduces stress. How ever make sure you keep the sensors clean or the cruse control will not slow the car down. Happen twice to me and it is exciting. My sensor are always clean now."

Got inside but it said the Control Fob was unknown and would not start. After I exited the car and used the open and close feature on Control Fob the car knew me again. It now started. Have not taken it to the dealer yet but this is on top of list when 20,000 mile service is due."
