Saving with golf ball structure
Mythbusters Test with golf ball structure gave the results according gassavers.org:
Clean car 26.4 mpg / 8.91 l/100km
Dirty car covered in chunky mud 24 mpg / 9.8 l/100km
Golf ball structure 29.6 mpg / l/100km 7.95 ~ 10% saving Despite the added weight of the clay structures. Car covered in 850 pounds of clay, with thousands of golf ball dimples:
   

Air resistance definition of Fastskinz film. They speak of up to 20% savings:

Here's a good theory to real golf ball.
Quote:Some golf ball manufacturers have even started including dimples with sharp corners rather than circular dimples since research indicates that these polygonal shapes reduce drag even more.
   

The shape of the holes is not critical, I conclude from the quotation.
If that happens, I'll paste my car with carpet anti-slip mats.
   

Does anyone have experience with double-sided tape on the car paint?
How can I easely remove it after the test?

RE: Saving with golf ball structure
I have SOOOO wanted to do this on my own car but have been lacking in time to do such things myself. I would start with an aerodynamic hatch back, think anything sporty like my ford probe. Remove the rear glass and replace with plexiglass. Dimple the plexi with heat into golf ball texture. On the roof cut out the steel and replace it with a super large plexi sunroof with golf ball dimples. You could make a bumper out of fiberglass with dimples, and do around the rear quarters. Only do the back of the car, and over the roof. You will see the most savings there, the front does not really need treated. The object is to reduce the wake and you want to smooth it off as it's coming off the back.

I found on the market "Bauhaus" self-adhesive joints-strips (5cm * 20m CHF 4.80).
So far I have used 4 wheels of strips. The liability feels insecure (less sticky), but all stripes were tuned this working week. Braved the strong wind.

Already on the weekend I could hardly believe the consumption:

Normal value: 7.50 l/100km (31.36 mpg)
Weekend: 6.96 l/100km
Workingweek: 7.02 l/100km (33.51 mpg) 6.4% saving

ROI:
Costs: (4x = CHF 4.80 19.20),
Savings / 100km: (7.50-7.02) 0.48 * CHF1.69 CHF/ l petrol lead free = CHF 0.81
ROI: = (19.2/0.81) * 100 = 2'370 km

Question RE: Saving with golf ball structure

Yes it is.
But now I know, that it works.

If it wouldn't work, I could take it easy away, because the glue on the ribbon is insecure sticky. My financially lost isn't big.

Now I can buy a Fastskinz MPF-Plus film for 1000 CHF and I reach my Return on Investment (ROI) in (1000/0.81*100) = 123'456km Shocked

I will live with it. My car looks like uggly Cool

Open question are:
  1. How long the ribbons resists the rain
  2. What will happen in winter (ice is falling behind me Crazy )
  3. How long I can live without a carwash (see at Mythbusters Test)
  4. What are the lowcost alternatives
  5. When I glue ribbons to the rest of my car, what will be the saving
  6. Which ribbon I could take away, without changing the saving

More Ribbons (stripes) on the entire roof, rear doors and front fenders do not have brought greater savings .
