Towing Mileage Calculator: What Your Tank Actually Gets You With a Trailer On
Every brochure lists an unloaded mpg number nobody sees once a trailer's hitched up. This calculator covers major vehicle brands from around the world, takes your actual unloaded fuel economy and trailer specs, and predicts what your real towing mileage and range will look like, not the optimistic number on the window sticker.

Weight explains half the mileage drop, shape explains the rest
Owners after a figure specific to their exact vehicle should use the towing capacity by VIN feature in the identify panel above, since engine and drivetrain choice genuinely shift the certified number. Full-size pickups and body-on-frame SUVs from Ford, Chevrolet, RAM, Toyota and Nissan lead the range with the strongest global towing figures, mid-size trucks and SUVs follow with solid numbers, and compact hatchbacks and sedans from nearly every brand simply were not built with a tow bar in mind, which this calculator states plainly rather than guessing.
Rolling resistance
Heavier trailers cost mileage at any speed, in town or on the highway.
Aerodynamic drag
Tall, boxy trailers cost more mileage above 55 mph than low ones of equal weight.
The real number
This calculator factors weight and shape together, not weight alone.
No brochure numbers
Compact hatchbacks and sedans get an honest not-rated flag, not a fabricated figure.
The full worldwide towing capacity chart
Every brand and model below loads straight into the calculator with a single click. Vehicles with no meaningful towing rating are marked plainly rather than left to guesswork.

Frequently asked questions
How much does towing a trailer reduce fuel mileage?
Typically 20 to 45 percent, depending on trailer weight and frontal shape. Aerodynamic drag matters as much as weight once speeds climb above about 55 mph.
What is a realistic towing range on a full tank?
For a typical half-ton truck averaging 20 mpg unloaded with a 26 gallon tank, towing often drops that to 12 to 14 mpg, cutting a 500 mile unloaded range down to roughly 310 to 360 miles.
Does trailer shape matter more than trailer weight for mileage?
Both matter, but at highway speeds aerodynamic drag from a tall or boxy trailer can cost more mileage than the extra rolling resistance from weight alone.
Which vehicles worldwide can actually tow heavy trailers?
Full-size pickups and body-on-frame SUVs from Ford, Chevrolet, RAM, Toyota and Nissan carry the strongest global figures, while compact cars from nearly every brand carry little or no factory towing rating.
