One week out from their Geneva Motor Show debut, Nissan has revealed the full details of the updated Nissan Pathfinder and Nissan Navara ranges.

Headlining the mid-life upgrade is an all-new direct injection V6 turbodiesel.

Developed by the Renault Nissan Alliance, the unique power plant sits at the unusual vee angle of 65 degrees and its block is made of Carbon Graphite Iron, which Nissan says offers all the stiffness and noise absorption benefits of cast iron without the weight penalty.

Power output peaks at 170kW and torque is a class-leading 550Nm between 1700 and 2500rpm. All of this is achieved while complying with Euro 5 standards, thanks to Exhaust Gas Recirculation which reduces NOx emissions and a metallic oxidation catalytic converter, exothermic catalyst and a catalytic diesel particulate filter.

Tip:

Engine Bay Protection<br> Placing a tarp across the front of the 4x4 minimizes water entering the engine bay by creating a bow wave, provided forward momentum is maintained. The result is less water for the radiator fan to spray over the ignition system, less chance of water entering the air intake and less likely for the fan to propel its way up to and through the radiator. Diesel 4x4 's are usually better for water crossings as you do not have the ignition system to worry about. Water in the ignition system usually results in a stalled engine and not actual engine damage, though this is of little comfort when you find yourself stuck in the middle of a crossing. Depending on the water depth, its advisable to climb out of your window rather than open the door and flood your carpets. To minimize stalling from a wet ignition, it's a good idea to spray all the ignition system with water repellent beforehand.
