Is it related to the Nissan Navara?
Yes, it shares its platform and the 2.3 dCi engine. Our experience with the Navara applies to a good part of this vehicle.
Will I notice a difference when towing?
That is exactly where it shows: the extra mid-range torque reduces the need to change down on gradients with a trailer or a full bed.
How does it differ from the X-Class entry?
This covers the X 250 version specifically. Our history records the model under several designations, so check both.
