[FIXED] How can I convert a folder into a sub domain?

Issue

I have a website that looks like this (the Ferrari is not a physical folder is an alias virtual):

www.example.com/en/ferrari

and I would like to convert this site into a sub-domain, like so:

ferrari.example.com

or something like:

ferrari.example.com/en/

---

The idea is to have all sub-pages from the Ferrari section working inside the sub-domain.

I don't know if this is even possible, all my .htaccess test didn't worked out. I am searching for a re-write rule but I don't seem to find it.

EDIT:

Let me rephrase the question, I don't want to REDIRECT from example.com/ferrari to ferrari.example.com

What I want is to show the example.com/ferrari site when someone opens ferrari.example.com. That is the difficult part. If someone opens ford.example.com, I want to show all the pages that are inside example.com/ford.

Solution

You can use that in your root .htaccess:

RewriteEngine on 
RewriteCond %{HTTP_HOST} ^ferrari\.example\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/en/ferraricars [NC]
RewriteRule ^(?:en/)?(.*) en/ferraricars/$1 [NC,L]

Work with ferrari.example.com/en/other and ferrari.example.com/other -> example.com/en/ferraricars/other
