My 2002 VW Passat 1.8T Tiptronic has an unscrewable antenna.
What really surprises me is that the 42 mpg Chevy Cruise Eco has the same type of antenna.
It is swept back, but at my usual 55-62 mph driving speed with all windows closed, would it make any difference on a 200 mile all highway trip? My car has a 0.27 coefficient of drag, would removing the antenna lower it to something like 0.2695 or something?
What if I lowered my cars, got rid of my heavy 15" alloy wheels, replaced them with light 15" steelies with moondisc hubcaps, and got a more aerodynamic sharkfin antenna?
Would those 3 mods be enough to lower my coefficient if drag to 0.26 and raise my EPA highway fuel economy from 28 mpg to 30 mpg?

That one mod is sort of like cutting one spoke from your bicycle wheel. Try that and see if its easier to pedal thus saving some energy, you won't need to ride 200 miles to find out. I can't explain why VW doesn't use radio antenna wires in their windshields that was done years ago on USA vehicles.

Note only downhill will you be able to test the spoke removal advantage at speeds of 55-62 mph. Thinking so. LOL "GL".....

They are removable so you can take them off when you go into a car wash so they are not damaged, it has nothing to do with mpg.

I don't believe you'd see a measurable difference, but I'd wouldn't mind seeing someone test it out to see if there's a measurable difference.

That would help stop the commercials/jargon bombardment, you might get bored....... If driving alone....... Realize that more concentration on things ahead can save fuel with right foot cooperating nicely... Skills is the answer! really! I know many books have been written on Skills... LOL

Minor gas savings and the possibility of a huge ticket or a nasty wreck - not worth it!

yes, you can't hear the radio which causes less wind friction.

I would maybe just put on another wax job to your vehicle and leave the antenna connected, then not feel guilty, keep your ears Happy on the trip, preventing wrinkles/frowns to a minimum (check mirror)results.
