This page collects every fuel-economy figure the EPA publishes for the 2024 Audi A3 quattro. 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. 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.

Key takeaways

Fuel economy at a glance

These are the EPA's official ratings for the 2024 Audi A3 quattro. 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.

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).

Combined MPG 30 MPG
City MPG 27 MPG
Highway MPG 34 MPG
Annual fuel cost $2,000
Tailpipe CO₂ 299 g/mi
Fuel type Regular

How the 2024 Audi A3 quattro compares

The 2024 Audi A3 quattro returns 30 combined MPG. Cars in the Subcompact Cars class for the same model year average 34.9 MPG, which puts this car behind the class average by about 14%.

The most efficient car in the Subcompact Cars class for the 2024 model year is the BMW i4 eDrive35 Gran Coupe (18 inch Wheels) at 120 MPG. The bar chart below puts the Audi A3 quattro alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2024 model year (across all classes) returns 40.9 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 2024 model year is on its own page.

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 regular gasoline, which is $3.99/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 500 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $1,000
Average driver, 15,000 miles per year $2,000
Heavy driver, 25,000 miles per year $3,333

Year-over-year MPG for the Audi A3 quattro

The EPA has rated the Audi A3 quattro across 19 model years, from 2006 Audi A3 quattro through 2026 Audi A3 quattro. 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 2006 Audi A3 quattro returned 21 MPG. The most recent 2026 Audi A3 quattro returns 28 MPG. That is an improvement of 7 MPG over 20 model years, the kind of gain that usually comes from smaller engines, hybrid systems, or aerodynamic redesigns.

Specifications

The 2024 Audi A3 quattro runs a 2-liter 4-cylinder turbocharged engine paired with a automatic (am-s7), sending power through 4-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.

  • Is the 2024 Audi A3 quattro fuel efficient?
    Not particularly. The 2024 Audi A3 quattro returns 30 combined MPG, which trails the average car in the Subcompact Cars class for the same model year by about 14%.
  • What MPG does the 2024 Audi A3 quattro get?
    The EPA rates the 2024 Audi A3 quattro at 30 combined MPG, 27 MPG in city driving, and 34 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 2024 Audi A3 quattro per year?
    The EPA estimates an annual fuel cost of $2,000 for the 2024 Audi A3 quattro. 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.
  • What fuel does the 2024 Audi A3 quattro use?
    The EPA lists the 2024 Audi A3 quattro as running on regular gasoline. Using a different grade than the manufacturer specifies can affect fuel economy and engine longevity.

    Yes. The first EPA-rated Audi A3 quattro, the 2006 Audi A3 quattro, returned 21 combined MPG. The most recent 2026 Audi A3 quattro returns 28 MPG, an improvement of 7 MPG over the run.
  • How much CO₂ does the 2024 Audi A3 quattro emit?
    Tailpipe CO₂ emissions are 299 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 4,485 kilograms of CO₂.
  • What is the difference between the city and highway MPG of the 2024 Audi A3 quattro?
    City driving returns 27 MPG and highway driving returns 34 MPG, a gap of 7 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 2024 Audi A3 quattro?
    The 2024 Audi A3 quattro has a 2-liter 4-cylinder turbocharged engine (EPA description: SIDI; Mild Hybrid). 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.
