Do all modern steering wheels no longer have an inner metal ring?

I once saw a Citroen DS, about BJ `73, which was burnt out. The plastic of the steering wheel was melted away and it remained a metal ring. Now I saw on the TV a burnt out Phaeton, there was nothing to see from the steering wheel. From the hub was finished. Do all modern cars have steering wheels that are only made of plastic, without inner metal ring, or do some still have it?
