39 mpg thus the cargo box on the roof increased fuel consumption by about 5 compared to the baseline.
When consumer reports tested how roof racks affected fuel economy in 2013 they noticed a 5 mpg drop at highway speeds from an empty rack.

Fairings can be custom made to fit your vehicle with pre made artwork or custom designs.
I drive mostly highways each day too.
Wind fairings will enhance your vehicle s contour to help cut through the wind with less drag.
Enhance your conversion van truck or car roof rack with a custom fairing.
Yeah you have to admit they do make your bare roof rack look sleeker and fancier.

Reduce air resistance wind noise and increase gas mileage.
Get it as soon as fri oct 2.
Some drivers may see their gas mileage drop by as much as 20 percent depending on vehicle type and type of roof rack.
He found that compared to the baseline of no roof rack the empty rack reduced his mpg by 12 7 and the roof rack with a bicycle reduced it by a whooping 27 3.
The decrease in your mpg miles per gallon will actually pay for the wind fairing you are getting your vehicle.
If you must travel with a loaded roof rack try to choose the most aerodynamic roof rack you can.

With my roof rack off i average 310 miles on a tank of gas when the winter time comes and the rack on with fairing i get on average 280 miles per tank.
So if your car usually gets 30 mpg on the highway and you add a full roof rack your highway gas mileage will drop to 24 27 mpg.
This is most likely an effect of crappy winter gas blends and or winter tires if you have them not the rack.
42 mpg roof rack with thule dynamic 800 aerodynamic cargo box.

The roof rack mpg experiment he compared the gas mileage of his car at 54 7 mph 88 kph with 1 no roof racks 2 an empty roof rack and 3 a mountain bike on the roof rack.
Adding a bike to the equation caused fuel consumption to jump by 35 compared to their baseline settings.
