Next modification : Aerobelly

Good idea. My belly pan was worth about 10% FE increase.

Ok, this idee with the wipers -> illegal in germany.
I try to change the endposition of the wipers.

Hi,

at the time i try to simulate all my mods via CFD.
So i build a simple Version from my Polo86C in SolidWorks and build in the changes.

I hope i could tuned this mods in this time of development to low the cost.

Here the Model and a modified version.

I public the calculates later

Hi,

standard polo (digital) : cw 0,335 A:1,64m² -> cwA:0,55m²
tuned polo (digital): cw 0,179 A:1,6m² -> cwA: 0,29m²

Improvent: nearly 100% better cwA

And the details are not build in.. (wheelspoiler, airflaps,...)

I think i could reach 0,18 in real life

I don't see any reason why you would not make it to your Cd target.It would be a significant advance.

Very cool! I once tried it with my 2F coupe 1.05 4-speed and later with my 2F steilheck 1.3 5-speed. I called it my old skool bluemotion

. I was active on the polo86c.nl website, but have sold all my polo's now.

Good luck on trying to maximise the consumption, maybe try to get a 1W diesel

.

I used a tuned 3F Gasoline engine with about 90-100hp.
The W1 with a G40 Loader are better, but i need a "Umweltplakette" to drive through different cities.
No chance with this old diesel.

And now the reworked version

Ahh, the 3F engine. Multipoint injection instead of monopoint! Good one, was it standard in the car or did you change the engine (or the cylinderhead)?

This was my polo coupe

- grill blocked with clear tape
- 135 tires
- smooth hubcaps like EkoPolo concept
- rearskirts, these were scrapped and went for clear tape later
- AAU engine, best result was around 5,1 liter per 100km
