We thought this iteration of the A4 was the best version of the car we'd ever tested up to that point. It feels solid, handles nimbly and the ride is firm, but well controlled. Braking performance and emergency handling are excellent. The four-cylinder turbocharged engine is smooth and civilized. The cabin is quiet and the interior finish is first-rate. All-wheel drive adds peace of mind, but hurts fuel economy.

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).
NA
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

Worse Better
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.

Anonymous, OR (2009 Audi A4 2.0T 3.2-L V6)

"Timing chain has apparently stretched causing the cam timing to fluctuate thereby causing intermittent horrible engine performance. This is on an engine/car that has been driven modestly by my wife, never overheated or damaged in any way, and properly maintained using only top quality synthetic oil changed at 5K intervals. Who designs a timing chain that, within only 140K miles, stretches to the point that the car becomes borderline un-drive-able? I could understand a chain timing tensioner being defective and not doing its job, or a wear item such as a timing belt failing. But a timing chain stretching to the point where the tensioner cannot compensate? Where is the storied precision German engineering? End result is an approximate $2500 repair bill at the dealer."

James R., CA (2009 Audi A4 3.2 3.2-L V6)
Thermostat

"Replacing the thermostat is usually a relatively inexpensive repair in any other brand car on the market. However, Audi, in its engineering ineptitude designed the thermostat and water pump as one integral unit. So, replacing the thermostat becomes a major $400+ repair requiring replacement of the entire water pump assembly."

John G., PA (2009 Audi A4 2.0T 2.0-L 4 Cyl turbo)

"The thermostat set an error code (but did not noticeably malfunction) at approx 80,000 miles. Replacing the thermostat (unlike most cars that I have owned) requires replacement of the entire water pump, resulting in a total repair bill of approximately $800 (if I recall correctly) which was exacerbated by the lack of availability of parts. The net result was 3 days in a loaner car and $800 poorer"
