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.

Key takeaways

  • The most efficient car in the Sport Utility Vehicle - 4WD class for the 2007 model year is the Ford Escape Hybrid 4WD at 27 MPG.
  • EPA estimates this car costs around $6,500 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 2007 BMW X3 3.0i. 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 20 MPG
City MPG 17 MPG
Highway MPG 24 MPG
Annual fuel cost $3,450
Tailpipe CO₂ 444 g/mi
Fuel type Premium

How the 2007 BMW X3 3.0i compares

The 2007 BMW X3 3.0i returns 20 combined MPG. Cars in the Sport Utility Vehicle - 4WD class for the same model year average 17.3 MPG, which puts this car ahead of the class average by about 16%.

The most efficient car in the Sport Utility Vehicle - 4WD class for the 2007 model year is the Ford Escape Hybrid 4WD at 27 MPG. The bar chart below puts the BMW X3 3.0i alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2007 model year (across all classes) returns 18.7 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 2007 model year is on its own page.

Trim variants rated for 2007

The EPA rates 2 separate variants of the 2007 BMW X3 3.0i. 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
3L, 6-cyl, Automatic (S6) 4-Wheel or All-Wheel Drive 20 MPG 17 MPG 24 MPG $3,450
3L, 6-cyl, Manual 6-spd 4-Wheel or All-Wheel Drive 19 MPG 16 MPG 24 MPG $3,650

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

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $1,725
Average driver, 15,000 miles per year $3,450
Heavy driver, 25,000 miles per year $5,750

Compare against other Sport Utility Vehicle - 4WD for 2007

The Ford Escape Hybrid 4WD leads this group at 27 MPG, 7 MPG ahead of the 2007 BMW X3 3.0i.

Specifications

The 2007 BMW X3 3.0i runs a 3-liter 6-cylinder engine paired with a automatic (s6), 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.

    Yes. The 2007 BMW X3 3.0i returns 20 combined MPG, which beats the average car in the Sport Utility Vehicle - 4WD class for the same model year by about 16%.
  • What MPG does the 2007 BMW X3 3.0i get?
    The EPA rates the 2007 BMW X3 3.0i at 20 combined MPG, 17 MPG in city driving, and 24 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 2007 BMW X3 3.0i per year?
    The EPA estimates an annual fuel cost of $3,450 for the 2007 BMW X3 3.0i. 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 2007 BMW X3 3.0i require premium gas?
    Yes. The EPA lists the 2007 BMW X3 3.0i 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.
  • How much CO₂ does the 2007 BMW X3 3.0i emit?
    Tailpipe CO₂ emissions are 444 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 6,665 kilograms of CO₂.
  • What is the difference between the city and highway MPG of the 2007 BMW X3 3.0i?
    City driving returns 17 MPG and highway driving returns 24 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 2007 BMW X3 3.0i?
    The 2007 BMW X3 3.0i has a 3-liter 6-cylinder engine.
  • What transmission and drivetrain does the 2007 BMW X3 3.0i have?
    The 2007 BMW X3 3.0i comes with a automatic (s6) 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 2007 BMW X3 3.0i compare to the best car in its class?
    The most efficient car in the Sport Utility Vehicle - 4WD class for the 2007 model year is the Ford Escape Hybrid 4WD at 27 combined MPG. The BMW X3 3.0i returns 20 MPG, a gap of 7 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
  • How much more does the 2007 BMW X3 3.0i cost in fuel compared to an average car?
    The EPA estimates that over five years, the 2007 BMW X3 3.0i will cost about $6,500 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.
