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.
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.
What does the 350 CDI V6 gain?
It is the higher-output version with more absolute torque, and it responds well to a measured map on standard hardware.
