hi all.
just came across this you tube video and was wondering if they put these dimples on a golf ball to reduce its drag,then wonder how dimples would go on a vehicle?
could this be on our vehicles in the future?

Hi Mark
One big problem a golf ball turns in flight and the dimples take air pressure from the front of the ball to the rear where there is a slight vacuum in flight and therefore the ball travels further than having no dimples at all Dimples on your vehicle would only help if you were rolling down an
embankment with the car rolling over and over you would do it faster and further !!!!!

Didn't seem to make any difference to
mine which has gone in today to get the damage from
Perth's March hailstorm repaired. Hopefully i will get it back before Christmas ... i get the feeling that the hail damaged cars are not a priority for an industry that is usually flat out dealing with everyday crashes. Panel
shop had a
sign saying there is a six-month wait still for a start date to repair hail damage.
Cheers

Pretty sure Team Dynamik, a now defunct team that ran in V8 Supercar, tried this sort of "coating" on one their racecars once.
They ran an unauthorised test day up at
Woomera way back in 2004 and from memory got fined for "illegal testing..."

Mythbusters did a test on this and made a car covered in clay and put dimples all over it. It was more economical to run.
I think they also found that a dirty car was cheaper to run than a clean one..........??????????

Doesn't work Mark. My wife manages to put dimbles of varying sizes over the body work of her car plus careless people in carparks have added a few extra!! Interesting video though & thanks for sharing. LOL

Damn.... I've lost sound on my puter so I could only watch...
As I understand it, the dimples create pockets of air so that most of the friction ends up being air-on-air. So... dimpled cars make sense.

Hey Mark,
I know a few women with dimples on the rear ends and it doesn't make them any faster/quieter or more economical.
Running for cover now.
