By adding some discrete drag reducing under body work, I have calculated it would be possible to reduce the car's drag enough to reduce fuel consumption by about 10%

This also turns a 100mph corsa into a 105mph Corsa :)

I was thinking of making a prototype to test my calculations, if it does work I thought about turning it into a business. So I wanted to ask would you buy such a product? If so how much would you pay for it?

Cheers guys :thumbs_up:

If it would work, firstly why haven't car manufacturers spend millions a year on research and development already done it?
Secondly if you are correct and it works I would patent it before it us copied as you will be a very rich man.

1) I have been studying automotive engineering for 3 years I'm pretty sure it works

2) similar technology is on new cars however there are no after market products as far as I'm aware

3) A car usually has been designed for 5 years before it goes in production, so 1995 Corsa is designed with 1990 fuel prices, it doesn't warrant Millions on drag reduction research.

4) No magnets! :)

I'm almost willing to bet my years salary on saying there is literally ZERO scientific evidence or testing behind these claims.
Although the claims made in the first post seem a little optimistic i think he may actually have a point about drag etc.
However putting somthing that is proven to work into production is unlikley and so is the 10% claim. I have no dout though that drag CAN be reduced but gains from it will be very small or non exsistant IMO.

Most of my research comes from this book http://www.amazon.co.uk/gp/product/0768000297/ref=oss_product

10% reduction is based upon driving at 70mph at lower speeds air resistance is less so drag is also reduced. So yeah I suppose the catch is motorway driving only.

And also a 10% fuel saving might only be about £150 based on 10000 miles a year. So I could see why people wouldn't bother.

Interesting ideas here.

The Corsa is a fairly well rounded design.... it should be more effiect than a Nova with its chizzeled squared off good looks! lol
Vauxhall has made one of the most aerodynamic cars ever produced in the shape of the Calibra, which would have been designed while the Mk2 Cavs and Mk1 Novas were about, just think adding the Tech from now to it.

I've seen the Ad for the New Focus, would shutting the lower grills really work??

I only drive around town, so for that reason, I'm out.

I drive a 4x4 around town, I want nature to die. If I wanted to save 10% (or a lot more) I could simply switch to a more efficient model.
For that reason, I am also out.

With an Automatic Car, and being the fact that it just plain sucks round town anyways due to not getting out of 1st or 2nd gear. For that reason im also out

I wouldn't be interested in actually using it but I'm going into automotive engineering so would be interested to see if it actually works.
