It is nowadays - 2017 Nissan Rogue is the European X-Trail. It wasn't the case in 2013 - it was just a qashqai. I don't think the previous gen X-Trail was even available in the US at all.

This is particularly visible on the inside:

I happen to own a 2013 Nissan X-Trail and it's a completely different vehicle, it's a blocky offroader, not an inflated Qashqai like it is nowadays.

Ah I think it's the "2017 Rogue Sport" which is a Qashqai. The Rogue remains an X-Trail (which has indeed been watered down since the 08MY offroad style)

funny that they would follow the same pattern as JLR, releasing a "sport" version which is actually based on a lower category - See 1st gen Range Sport

And then, because obviously it wasn't confusing enough, in Canada the Qashqai is a Qashqai, not Rogue Sport, but X-Trail is still a Rogue.
