Fuel economy at a glance

These are the EPA's official ratings for the 1990 Audi Coupe 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 18 MPG
City MPG 16 MPG
Highway MPG 22 MPG
Annual fuel cost $3,300
Tailpipe CO₂ 494 g/mi
Fuel type Regular

How the 1990 Audi Coupe quattro compares

The 1990 Audi Coupe quattro returns 18 combined MPG. Cars in the Subcompact Cars class for the same model year average 23 MPG, which puts this car behind the class average by about 22%.

The most efficient car in the Subcompact Cars class for the 1990 model year is the Geo Metro XFI at 47 MPG. The bar chart below puts the Audi Coupe 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 1990 model year (across all classes) returns 19.1 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 1990 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 833.3 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $1,650
Average driver, 15,000 miles per year $3,300
Heavy driver, 25,000 miles per year $5,500

Specifications

The 1990 Audi Coupe quattro runs a 2.3-liter 5-cylinder engine paired with a manual 5-spd, sending power through 4-wheel or all-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 1990 Audi Coupe quattro

Quick answers to the questions people most often search for when looking up the 1990 Audi Coupe quattro.

  • Is the 1990 Audi Coupe quattro fuel efficient?
    Not particularly. The 1990 Audi Coupe quattro returns 18 combined MPG, which trails the average car in the Subcompact Cars class for the same model year by about 22%.
  • What MPG does the 1990 Audi Coupe quattro get?
    The EPA rates the 1990 Audi Coupe quattro at 18 combined MPG, 16 MPG in city driving, and 22 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 1990 Audi Coupe quattro per year?
    The EPA estimates an annual fuel cost of $3,300 for the 1990 Audi Coupe 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 1990 Audi Coupe quattro use?
    The EPA lists the 1990 Audi Coupe quattro as running on regular gasoline. Using a different grade than the manufacturer specifies can affect fuel economy and engine longevity.
  • How much CO₂ does the 1990 Audi Coupe quattro emit?
    Tailpipe CO₂ emissions are 494 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 7,406 kilograms of CO₂.
  • What is the difference between the city and highway MPG of the 1990 Audi Coupe quattro?
    City driving returns 16 MPG and highway driving returns 22 MPG, a gap of 6 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 1990 Audi Coupe quattro?
    The 1990 Audi Coupe quattro has a 2.3-liter 5-cylinder engine (EPA description: (20-VALVE) (FFS)).
  • What transmission and drivetrain does the 1990 Audi Coupe quattro have?
    The 1990 Audi Coupe quattro comes with a manual 5-spd transmission and 4-wheel or all-wheel drive. All-wheel-drive variants typically read 1 to 3 MPG lower than the front-wheel-drive equivalent of the same engine, since the extra hardware adds weight and parasitic loss.
  • How does the 1990 Audi Coupe quattro compare to the best car in its class?
    The most efficient car in the Subcompact Cars class for the 1990 model year is the Geo Metro XFI at 47 combined MPG. The Audi Coupe quattro returns 18 MPG, a gap of 29 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
  • How much more does the 1990 Audi Coupe quattro cost in fuel compared to an average car?
    The EPA estimates that over five years, the 1990 Audi Coupe quattro will cost about $5,750 more in fuel than an average new vehicle of the same model year. The difference accumulates because the car uses more fuel per mile, not because of any one-off charge at the dealership.
