Well, ive just got myself a semi high roof 1999 ford transit.
Its fitted with a 2.5 diesel, weighs 1700kg, and i think about as aerodynamic as a tank.
Ive been averaging approx 30-something mpg ( uk ) which isnt too bad, around the city, driving very gently.
Any opinions on what sort of aero mods could be done to increase mpg?
I dont think anything can be done to the rear sadly.
Im thinking of blocking 1/2 the grill, sealing any front end gaps , installing a front end air dam.
Lowering isnt really an option.
Im going to install some " moon disc " trims for the wheels.
I think rear skirts would attract too much attention ( its a work van )
Here is a sample picture :
does anyone have a very rough estimate what i may see with a front air dam and grill block? or will i be wasting my time ?
