BMW 760li

What it costs to keep fuelled

$3,200a year, fuel only

The 2008 BMW 760li is EPA-rated at 15 MPG combined (13 city / 20 highway). Over 15,000 miles a year that is about 1000 gallons, $3200 a year in fuel, or $0.213 per mile at $3.20/gal.

Across its full 2003–2008 run it averages 15.7 MPG, falling by 1 MPG over 6 model years.

How this is worked out

  1. Start from the EPA combined figure for the model year — a laboratory test cycle run to a fixed procedure, not a road result. Where a year sold several engines or drivetrains, the trims are averaged and the trim count is printed beside the row so you can see how much averaging is behind it.
  2. Fix a pump price. This site keeps one reference price, $3.20 a US gallon, fixed JUL 2026 and printed next to every dollar figure it produces. It is an assumption with a date on it, not a quote — put your own price in.
  3. Fix an annual distance. Every annual figure on this site uses 15,000 miles a year, roughly the US average. A cost per year with no stated distance is not a number, it is a mood.
  4. Divide distance by economy for gallons, multiply by price for the year's fuel, divide price by economy for one mile. The per-kilometre line is that last figure divided by 1.609344 — the same money, in the unit most of the world drives in.
  5. Stop there. No depreciation, no tyres, no insurance, no servicing. This is the fuel line of the ledger and it is labelled as one; depreciation usually dwarfs everything on it.
gallons/yr = miles/yr ÷ MPG
fuel  $/yr = gallons/yr × $/gal
cost  $/mi = $/gal ÷ MPG
cost  $/km = cost $/mi ÷ 1.609344

Re-run the ledger at another pump price

Every line above rests on one pump price. Here is the same entry re-costed at six others, because the price is the part that changes while the test sheet stays put.

Questions asked across the counter

What MPG does the BMW 760li get?

The 2008 BMW 760li is rated at 15 MPG combined by the EPA — 13 city and 20 highway. Across all 6 model years in the database it averages 15.7 MPG, ranging from 15 to 16 depending on year and trim.

How much does a BMW 760li cost in fuel per year?

At 15 MPG and 15,000 miles a year, it burns about 1000 gallons — roughly $3200 a year with fuel at $3.20 a gallon, or $0.213 per mile. The EPA's own published annual figure for the 2008 model is $5150.

Has the BMW 760li become more efficient over time?

No — it has actually gone backwards, from 16 MPG in 2003 to 15 in 2008. That usually reflects the model growing heavier, more powerful, or moving upmarket rather than the engineering getting worse.

Is the BMW 760li efficient for its class?

It ranks 129 of 149 in the Large Cars class on current figures, against a class average of 21.6 MPG. That is 6.6 worse than typical for the class.
