VW Lupo 3L --> 2L

[Arturasz]

I think factory seat weight also not su much 8-9 kg. Please weight it if you will have opportunity

[Vekke]

Stock lupo 3l Front seat weights about 12.5 kg error tolerance is 0.5 kg.

Assistant front seat will be removed totally, and put only back when that is needed.

[Arturasz]

Ok I look forward to see your results ;]

[Vekke]

My custom seat weigted 4.5 kg at the moment when std Sparco race seat was 7 kg. Carbonfiber wrc version is in the same range than my current seat. There will come also ventilation with electric fan to cool off the driver.

Oh and its not finished yet .

It doesn't look very comfortable, for only modest weight savings.

Replacing the body panels with plastics is where the major weight gains are, like with this Golf:

Did you check also the picture with red paddings?

Its not as comfortable as OEM seat for sure but 5 times better than regular race seat.

Biggest problems with bucket seats are that your legs are tight together so your start to sweat easily.

In this seat I can move my legs and there is two electric fans to keep the air moving with adjustable speeds. after one month I will now how it will work in action.

I have previous experience from regular bucket seat from 5 years ago. In that 400 km long trip was too much for my back. Mainly due to leg issue.

To be able to remove 100 kg I have to change and modify pretty much everything I can because the factory has made the 3L body already 150 kg lighter...

Hi Vekke,

I've read your thread and I like it very much. Anyway I got this idea, that came to me while I was P&Ging. With the manual gearbox which is shifted by a robot, some logic and hacking & tweaking of the cuurent setup you may build an automated P&G system for your Lupo. With just 2-3 buttons to control it. You have everything that is needed. Start-stop feature, automatic gear shifting, automatic clutch. Just combine it together and voila!

Angles used on the side tried to get 10 degrees and the roof according to template C. When I try to fit it to the template it is quite close IMO :/.

How are legalities with such extended aerodynamic mods in our country?

I have had impression that extending outside of body lines would need reflectors at minimum, maybe even lights and still might be illegal, so I have limited my mods to bumper level?

Would like to get my next Kamm to extend further like this your photo shows.

Its illegal to make kammback any further than the body. Also its illegal to put any such things on your car which in newer than 1997. So any parts you put there are basicly illegal. In most cases police will understand, but you need to ready to pay some R&D costs made by police.

Good suggestion on the active P&G cruise control. If I would have skills to do it I propably would. You have few choices. Make mechanical system that pushes or pulls the standard gas pedal. That I could build easily. Make electrical verion which would fool the gas pedal positions to ECU. For that I dont have the skills.

But I think I will try to get some engineer to work on it as their graduation study/work .

Thanks from this, yet again one reason to dislike our car legislation system. I wonder if newer than 1997 includes 1997 too? Might need to get older specimen for aeromodding to avoid savings to go supporting our poor country
