Fuel economy at a glance

These are the EPA's official ratings for the 2015 BMW 335i xDrive Gran Turismo. 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 23 MPG
City MPG 20 MPG
Highway MPG 30 MPG
Annual fuel cost $3,000
Tailpipe CO₂ 379 g/mi
Fuel type Premium

How the 2015 BMW 335i xDrive Gran Turismo compares

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

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

Specifications

The 2015 BMW 335i xDrive Gran Turismo runs a 3-liter 6-cylinder turbocharged 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.

  • Is the 2015 BMW 335i xDrive Gran Turismo fuel efficient?
    Not particularly. The 2015 BMW 335i xDrive Gran Turismo returns 23 combined MPG, which trails the average car in the Large Cars class for the same model year by about 16%.
  • What MPG does the 2015 BMW 335i xDrive Gran Turismo get?
    The EPA rates the 2015 BMW 335i xDrive Gran Turismo at 23 combined MPG, 20 MPG in city driving, and 30 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 2015 BMW 335i xDrive Gran Turismo per year?
    The EPA estimates an annual fuel cost of $3,000 for the 2015 BMW 335i xDrive Gran Turismo. 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 2015 BMW 335i xDrive Gran Turismo require premium gas?
    Yes. The EPA lists the 2015 BMW 335i xDrive Gran Turismo 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 335i xDrive Gran Turismo become more fuel efficient over time?
    Combined MPG has stayed close to flat across the run. Both the earliest (2014 BMW 335i xDrive Gran Turismo, 24 MPG) and most recent (2016 BMW 335i xDrive Gran Turismo, 23 MPG) versions sit in the same range.
  • How much CO₂ does the 2015 BMW 335i xDrive Gran Turismo emit?
    Tailpipe CO₂ emissions are 379 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 5,685 kilograms of CO₂.
  • What is the difference between the city and highway MPG of the 2015 BMW 335i xDrive Gran Turismo?
    City driving returns 20 MPG and highway driving returns 30 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 2015 BMW 335i xDrive Gran Turismo?
    The 2015 BMW 335i xDrive Gran Turismo has a 3-liter 6-cylinder turbocharged engine (EPA description: SIDI).
  • What transmission and drivetrain does the 2015 BMW 335i xDrive Gran Turismo have?
    The 2015 BMW 335i xDrive Gran Turismo 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 2015 BMW 335i xDrive Gran Turismo compare to the best car in its class?
    The most efficient car in the Large Cars class for the 2015 model year is the Tesla Model S AWD - 70D at 101 combined MPG. The BMW 335i xDrive Gran Turismo returns 23 MPG, a gap of 78 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
