BMW Sedan Fuel Economy & Commute Range Table
EPA fuel economy and estimated combined driving range for the BMW 3 Series, 4 Series Gran Coupe, 5 Series, and 7 Series — the numbers that matter most for a daily NYC commute.
What is the gas mileage of a BMW 3 Series?
The 2026 BMW 330i is EPA-rated at 28 mpg city / 35 mpg highway / 31 mpg combined in rear-wheel drive, making it the most fuel-efficient sedan in BMW's current lineup. On a full 15.6-gallon tank, that works out to an estimated 480+ miles of combined-cycle range — enough for most Long Island City commuters to go a full week or more between fill-ups.
BMW Sedan Fuel Economy Comparison
RWD Base Trims| Model | City MPG | Highway MPG | Combined MPG | Fuel Tank | Est. Combined Range |
|---|---|---|---|---|---|
| 330i | 28 | 35 | 31 | 15.6 gal | ~484 mi |
| 430i Gran Coupe | 25 | 34 | 29 | 15.6 gal | ~452 mi |
| 530i | 27 | 35 | 30 | 18.0 gal | ~540 mi |
| 740i | 25 | 31 | 28 | 20.6 gal | ~577 mi |
Figures shown are EPA fuel economy ratings for rear-wheel-drive base trims and manufacturer-published fuel tank capacities. xDrive (all-wheel-drive) versions typically run 1-2 mpg lower across the board. Estimated range is calculated as combined MPG × tank capacity and will vary with driving conditions, climate control use, and options.

Why Fuel Economy Varies Across the Sedan Lineup
The pattern above tracks closely with size and weight: the compact 3 Series is the most efficient, the 4 Series Gran Coupe trades a little efficiency for its lower, sportier body, and the 5 Series and 7 Series prioritize a larger cabin and more standard equipment over maximum mpg. All four models share BMW's turbocharged inline-4 or inline-6 engines paired with an 8-speed automatic transmission, so the efficiency differences come down almost entirely to size, weight, and aerodynamics rather than powertrain technology.

Frequently Asked Questions
What is the gas mileage of a BMW 3 Series?
The 2026 BMW 330i is EPA-rated at 28 mpg city / 35 mpg highway / 31 mpg combined in rear-wheel drive, the most efficient sedan in BMW's current lineup.
How far can a BMW 5 Series go on a full tank?
The 530i has an 18-gallon tank and a 30 mpg combined EPA rating, for an estimated combined range of about 540 miles — actual range will vary with driving conditions and options.
Do xDrive all-wheel-drive models get worse gas mileage?
Yes, slightly. xDrive versions of the 3, 4, 5, and 7 Series typically see combined fuel economy drop by about 1-2 mpg compared to the rear-wheel-drive versions shown here, due to the added weight and drivetrain friction of the all-wheel-drive system.
Which BMW sedan has the longest driving range?
The 740i, thanks to its larger 20.6-gallon fuel tank, has the longest estimated combined range in the sedan lineup at roughly 577 miles, despite having a lower combined mpg rating than the 3 or 5 Series.
