This page collects every fuel-economy figure the EPA publishes for the 2011 Audi A8 L. 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

  • The most efficient car in the Large Cars class for the 2011 model year is the Hyundai Sonata at 27 MPG.
  • EPA estimates this car costs around $5,750 more in fuel over five years than an average new vehicle of the same model year.
  • Requires premium gasoline, which typically adds about 40 to 60 cents per gallon to the EPA's annual fuel cost estimate.

Fuel economy at a glance

These are the EPA's official ratings for the 2011 Audi A8 L. 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 21 MPG
City MPG 17 MPG
Highway MPG 27 MPG
Annual fuel cost $3,300
Tailpipe CO₂ 423 g/mi
Fuel type Premium

How the 2011 Audi A8 L compares

The 2011 Audi A8 L returns 21 combined MPG. Cars in the Large Cars class for the same model year average 18.2 MPG, which puts this car ahead of the class average by about 15%.

The most efficient car in the Large Cars class for the 2011 model year is the Hyundai Sonata at 27 MPG. The bar chart below puts the Audi A8 L alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2011 model year (across all classes) returns 20.8 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 2011 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 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).

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 2011 Audi A8 L runs a 4.2-liter 8-cylinder engine paired with a automatic (s8), sending power through 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 2011 Audi A8 L

Quick answers to the questions people most often search for when looking up the 2011 Audi A8 L.

  • Is the 2011 Audi A8 L fuel efficient?
    Yes. The 2011 Audi A8 L returns 21 combined MPG, which beats the average car in the Large Cars class for the same model year by about 15%.
  • What MPG does the 2011 Audi A8 L get?
    The EPA rates the 2011 Audi A8 L at 21 combined MPG, 17 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 2011 Audi A8 L per year?
    The EPA estimates an annual fuel cost of $3,300 for the 2011 Audi A8 L. 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 2011 Audi A8 L require premium gas?
    Yes. The EPA lists the 2011 Audi A8 L 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 A8 L become more fuel efficient over time?
    Combined MPG has stayed close to flat across the run. Both the earliest (2000 Audi A8 L, 18 MPG) and most recent (2023 Audi A8 L, 22 MPG) versions sit in the same range.
  • How much CO₂ does the 2011 Audi A8 L 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 2011 Audi A8 L?
    City driving returns 17 MPG and highway driving returns 27 MPG, a gap of 10 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 2011 Audi A8 L?
    The 2011 Audi A8 L has a 4.2-liter 8-cylinder engine (EPA description: SIDI).
  • What transmission and drivetrain does the 2011 Audi A8 L have?
    The 2011 Audi A8 L comes with a automatic (s8) transmission and 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 2011 Audi A8 L compare to the best car in its class?
    The most efficient car in the Large Cars class for the 2011 model year is the Hyundai Sonata at 27 combined MPG. The Audi A8 L returns 21 MPG, a gap of 6 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
