Hi.
In a default EIGRP configuration, when a new VPN tunnel is created, does EIGRP automatically distribute this new locally connected route?
Thank you.

Except case

Hello,
By Default EIGRP does not advertise any networks to anything. You need to configure what interfaces you want explicitly to participate in EIGRP, to include your VPN networks.
You can do this with a
network command
or a
redistribute command
If in the case you mean a tunnel interface make sure you dont advertise the tunnel interface IP/network and the interfaces associated with it both in EIGRP or you'll end up with recursive routing and it will bring the tunnel down.
If you want to avoid that I would create a static route for the physical interfaces to eachother and advertise the tunnel interfaces in EIGRP.
Hope that helps

if the
static routes
are not redistributed, then NO i guess (high level) - we need to look what configured on your side.

Yes, if you config redistrubte connect then any vpn local subnet will redistrubte into eigrp.

"Yes, if you config redistrubte connect then any vpn local subnet will redistrubte into eigrp."
if there is implemented the simple default EIGRP services, will the rout be identified and then propagated through the LAN?

The original post refers to a default eigrp configuration. I am not sure what that means.
To be able to give good advice we need more information. The best would be to post the complete current running config (with sensitive information disguised). If you do not want to give that then at least we need the output of the commands
show ip interface brief show run | section eigrp
