Fuel economy at a glance
These are the EPA's official ratings for the 2024 Audi Q4 40 e-tron. 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 | 103 MPG |
| City MPG | 112 MPG |
| Highway MPG | 94 MPG |
| Annual fuel cost | $750 |
| Tailpipe CO₂ | — |
| Fuel type | Electricity |
How the 2024 Audi Q4 40 e-tron compares
The 2024 Audi Q4 40 e-tron returns 103 combined MPG. Cars in the Standard Sport Utility Vehicle 2WD class for the same model year average 40.6 MPG, which puts this car ahead of the class average by about 154%.
Within the Standard Sport Utility Vehicle 2WD class for the 2024 model year, the Audi Q4 40 e-tron is the leader. No other car in the same class beat its 103 MPG rating. The bar chart below shows it alongside the class average and the average new car for some additional context.
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 electricity, which is $0.15/kilowatt-hour. 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 MPGe and the reference electricity price stay constant, only the annual mileage changes. Charging at home rather than at a public DC fast charger usually lowers the real cost below the EPA's published figure.
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $375 |
| Average driver, 15,000 miles per year | $750 |
| Heavy driver, 25,000 miles per year | $1,250 |

Specifications
The 2024 Audi Q4 40 e-tron is a fully electric vehicle. It is powered by 150 kw pmsm 3-phase. The EPA rates its driving range at 265 miles.
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 Q4 40 e-tron fuel efficient?
Yes. The 2024 Audi Q4 40 e-tron returns 103 combined MPG, which beats the average car in the Standard Sport Utility Vehicle 2WD class for the same model year by about 154%. -
What MPG does the 2024 Audi Q4 40 e-tron get?
The EPA rates the 2024 Audi Q4 40 e-tron at 103 combined MPG, 112 MPG in city driving, and 94 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 Q4 40 e-tron per year?
The EPA estimates an annual fuel cost of $750 for the 2024 Audi Q4 40 e-tron. 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 2024 Audi Q4 40 e-tron use gasoline?
No. The 2024 Audi Q4 40 e-tron is fully electric and runs on grid electricity. The MPGe figure on this page converts electricity use into a gasoline-equivalent so you can compare it directly to a regular car. -
How much CO₂ does the 2024 Audi Q4 40 e-tron emit?
The 2024 Audi Q4 40 e-tron produces zero tailpipe emissions because it runs entirely on electricity. The full carbon footprint of charging it depends on how the electricity on your local grid is generated, which varies a lot from one state to another. -
What is the difference between the city and highway MPG of the 2024 Audi Q4 40 e-tron?
City driving returns 112 MPG and highway driving returns 94 MPG. A flat (or city-better) split is the signature of a hybrid or electric drivetrain, where regenerative braking recovers energy that would otherwise be lost in stop-start city traffic. -
What motor does the 2024 Audi Q4 40 e-tron use?
The 2024 Audi Q4 40 e-tron uses 150 kW PMSM 3-Phase. Electric motors do not have a displacement or cylinder count the way a combustion engine does, so EPA reporting focuses on the motor type and battery system instead. -
What transmission and drivetrain does the 2024 Audi Q4 40 e-tron have?
The 2024 Audi Q4 40 e-tron comes with a automatic (a1) transmission and rear-wheel drive. -
