1997 Audi A4: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 1997 Audi A4. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. The EPA rates 3 separate variants of this car (different engine, transmission, or drivetrain combinations), and you can compare them side by side in the trims table. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Fuel economy at a glance

These are the EPA's official ratings for the 1997 Audi A4. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

When the EPA tests several variants of the same nameplate (for example, a front-wheel-drive version and an all-wheel-drive version), each gets its own rating. The figures shown here are the headline variant, taken as the configuration with the best combined MPG. The trims table further down covers all 3 variants side by side.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 1997 Audi A4 compares

The 1997 Audi A4 returns 21 combined MPG. Cars in the Compact Cars class for the same model year average 22.2 MPG, which puts this car behind the class average by about 5%.

The most efficient car in the Compact Cars class for the 1997 model year is the Volkswagen Golf/GTI at 37 MPG. The bar chart below puts the Audi A4 alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 1997 model year (across all classes) returns 18.9 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 1997 model year is on its own page.

Trim variants rated for 1997

The EPA rates 3 separate variants of the 1997 Audi A4. The differences come from the engine size, transmission type, and drivetrain (front-wheel drive, all-wheel drive, and so on). The same nameplate can land several MPG apart depending on the configuration you actually buy.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for premium gasoline, which is $4.61/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 714.3 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Audi A4

The EPA has rated the Audi A4 across 24 model years, from 1996 Audi A4 through 2020 Audi A4. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

The 1996 Audi A4 returned 20 MPG. The most recent 2020 Audi A4 returns 30 MPG. That is an improvement of 10 MPG over 24 model years, the kind of gain that usually comes from smaller engines, hybrid systems, or aerodynamic redesigns.

Compare against other Compact Cars for 1997

If you are cross-shopping the 1997 Audi A4, the most useful comparison is against the other cars in the Compact Cars class for the same model year. The list below shows the highest-MPG peers, ranked from most to least efficient. Click any of them to open its full page.

The Volkswagen Golf/GTI leads this group at 37 MPG, 16 MPG ahead of the 1997 Audi A4.

Specifications

The 1997 Audi A4 runs a 1.8-liter 4-cylinder turbocharged engine paired with a automatic 5-spd, sending power through front-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

Common questions about the 1997 Audi A4

Quick answers to the questions people most often search for when looking up the 1997 Audi A4.

• Is the 1997 Audi A4 fuel efficient?

  It is in line with the rest of the class. The 1997 Audi A4 returns 21 combined MPG, and the average car in the Compact Cars class for the same model year sits at 22.2 MPG.
• What MPG does the 1997 Audi A4 get?

  The EPA rates the 1997 Audi A4 at 21 combined MPG, 18 MPG in city driving, and 27 MPG on the highway. Real-world numbers depend on your driving style, the weather, and how loaded the car is.
• How much does it cost to fuel a 1997 Audi A4 per year?

  The EPA estimates an annual fuel cost of $3,300 for the 1997 Audi A4. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
• Does the 1997 Audi A4 require premium gas?

  Yes. The EPA lists the 1997 Audi A4 as requiring premium gasoline. Running it on regular can reduce performance and may affect engine warranties, so it is not a recommended way to save at the pump.
• Has the Audi A4 become more fuel efficient over time?

  Yes. The first EPA-rated Audi A4, the 1996 Audi A4, returned 20 combined MPG. The most recent 2020 Audi A4 returns 30 MPG, an improvement of 10 MPG over the run.
• How much CO₂ does the 1997 Audi A4 emit?

  Tailpipe CO₂ emissions are 423 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 6,348 kilograms of CO₂.
• What is the difference between the city and highway MPG of the 1997 Audi A4?

  City driving returns 18 MPG and highway driving returns 27 MPG, a gap of 9 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise.
• What engine is in the 1997 Audi A4?

  The 1997 Audi A4 has a 1.8-liter 4-cylinder turbocharged engine (EPA description: (FFS,TRBO)). Smaller turbocharged engines like this one tend to deliver bigger-engine power on demand while keeping fuel economy closer to a non-turbo version of the same displacement.
• What transmission and drivetrain does the 1997 Audi A4 have?

  The 1997 Audi A4 comes with a automatic 5-spd transmission and front-wheel drive.
• How does the 1997 Audi A4 compare to the best car in its class?

  The most efficient car in the Compact Cars class for the 1997 model year is the Volkswagen Golf/GTI at 37 combined MPG. The Audi A4 returns 21 MPG, a gap of 16 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
