My Aerotail on Audi A2
 

Hello,

After seeing some boattails online. I decided to built one that also functions as a luggage carrier. So we can go camping with our 2 kids, bring all the stuff and not have to use an mpg-killing trailer or roofrack.
I used a trailerhitch bikerack as a base. It can tilt so you can open the trunk.

When I drive around 65 M/h on the highway, I get 10% more Mpg.
I once got 92Mpg (2,5 l/100Km) on a 135 mile trip, with 4 people and full of luggage.

I'm thinking of making a foam rim to fill the gap between the car and the tail and to improve the bottomside of the tail.

I can still see through the upper part of the rear window.
I have a webpage (in dutch) with more pictures.


I also made an electric recumbent motorcycle.
I'm a friend of the guy who made the mintcolored fully faired honda.
I still have to make a better fairing for it.

wow!!

let me be the first to welcome you!!

Very nice.

I saw your project mentioned on this site before, and I was hoping to see you join and share some details with us. A big welcome !
You have taken one of the most streamlined production vehicles ever offered to the public and greatly improved on its aerodynamics.
Welcome !

I like the font that you chose for the text on the sticker. It looks professional.
Nice message too.
Do you plan to add a small clear section on the back to see out of ?

Very neat fabrication and good idea to use the hitch / rack as a mount.

Possible retail potential (niche market)?

Nice work. Very professional looking.

As a fellow boat tail driver, that looks great!

For this it may be worth PM-ing user Vekke who has a business doing aero stuff in Europe.

Most people who see the Aerotail tell me to get a patent or to start selling them.
I run a succesfull business making Velomobiles (fully faired 3wheeled recumbent bicycles)
I have no intention of starting a production of aerotails.
I think there could be a market for a trailerhitch aerotail that would fit on several cars.
You can buy a trailerhitch luggagecarrier here in holland, but it's just a square box. They could simply change the shape to a more aerodynamic one and make 3 or 4 different sizes/shapes to fit most cars, hatchbacks SUV's etc.

Oh, here's a picture of my electric motorbike
