Well, "newer" as in "last thirty years"? (I have found "new" and "old" model definitions vary betwixt the Americas and Europe, on some things. ;) ) and yes, it does exist! And works beautifully. I love my self-cleaning oven. I lock it (because it does get dangerously hot, it won't turn on to that feature without locking and won't unlock until it's finished), turn it to the setting and leave it alone (with all my windows open) for five hours or so and voilà! All I have to do is take some damp paper towel and wipe up the ash.

I think our current oven and stove is about ten to twelve years old - we've been in this apartment for six years, and it was by no means "new" when we moved in.
