How does this differ from the other X-Class entries?
Our history records the model under several designations. Each group covers different units, so it is worth checking all of them.
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.
Is it related to the Nissan Navara?
Yes, it shares its platform and much of its engineering. Our experience with the Navara applies to a good part of this vehicle.
