This page collects every fuel-economy figure the EPA publishes for the 2009 BMW M5. 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 2 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.

Key takeaways

  • Returns 39% worse combined MPG than the average car in the Midsize Cars class for the 2009 model year (21.3 MPG class average).
  • The most efficient car in the Midsize Cars class for the 2009 model year is the Toyota Prius at 46 MPG.
  • EPA estimates this car costs around $15,750 more in fuel over five years than an average new vehicle of the same model year.
  • Subject to the federal Gas Guzzler Tax, which applies to passenger cars rated below 22.5 combined MPG.
  • 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 2009 BMW M5. 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 2 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).

Combined MPG 13 MPG
City MPG 11 MPG
Highway MPG 17 MPG
Annual fuel cost $5,300

How the 2009 BMW M5 compares

The 2009 BMW M5 returns 13 combined MPG. Cars in the Midsize Cars class for the same model year average 21.3 MPG, which puts this car behind the class average by about 39%.

The most efficient car in the Midsize Cars class for the 2009 model year is the Toyota Prius at 46 MPG. The bar chart below puts the BMW M5 alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2009 model year (across all classes) returns 19.5 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 2009 model year is on its own page.

Trim variants rated for 2009

The EPA rates 2 separate variants of the 2009 BMW M5. 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.

Engine and transmission Drive Combined City Highway Annual cost
5L, 10-cyl, Manual 6-spd Rear-Wheel Drive 13 MPG 11 MPG 17 MPG $5,300
5L, 10-cyl, Automatic (S7) Rear-Wheel Drive 13 MPG 11 MPG 17 MPG $5,300

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 1153.8 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $2,650
Average driver, 15,000 miles per year $5,300
Heavy driver, 25,000 miles per year $8,833

Year-over-year MPG for the BMW M5

The EPA has rated the BMW M5 across 20 model years, from 1991 BMW M5 through 2021 BMW M5. 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.

Combined MPG has stayed in roughly the same range across the run. The peak rating came with the 2013 BMW M5 at 17 MPG.

Specifications

The 2009 BMW M5 runs a 5-liter 10-cylinder engine paired with a manual 6-spd, sending power through rear-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.

  • What MPG does the 2009 BMW M5 get?
    The EPA rates the 2009 BMW M5 at 13 combined MPG, 11 MPG in city driving, and 17 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 2009 BMW M5 per year?
    The EPA estimates an annual fuel cost of $5,300 for the 2009 BMW M5. 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 2009 BMW M5 require premium gas?
    Yes. The EPA lists the 2009 BMW M5 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 BMW M5 become more fuel efficient over time?
    Combined MPG has stayed close to flat across the run. Both the earliest (1991 BMW M5, 13 MPG) and most recent (2021 BMW M5, 17 MPG) versions sit in the same range.
  • How much CO₂ does the 2009 BMW M5 emit?
    Tailpipe CO₂ emissions are 684 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 10,254 kilograms of CO₂.
  • What is the difference between the city and highway MPG of the 2009 BMW M5?
    City driving returns 11 MPG and highway driving returns 17 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 2009 BMW M5?
    The 2009 BMW M5 has a 5-liter 10-cylinder engine.
