Launched at the Geneva Motor Show, the improved new-look Nissan Navara and Pathfinder models are due on sale across Europe in April. They will be followed two months later by the new 3.0-litre V6 diesel flagship models.
The new direct injection V6 turbodiesel has been developed by the Renault Nissan Alliance to deliver high levels of performance with strong economy, competitive emissions and class-leading refinement.
The key element of the new V6 – with an unusual vee angle of 65 degrees – is the material chosen for the engine block. Alliance development engineers chose Compacted Graphite Iron (CGI), a material that offers all the benefits of cast iron, including high levels of stiffness and noise absorption, without the weight penalty. And while CGI is heavier than a pure alloy block there is no need to add stiffening ribs or extra sound deadening material so the weight gain is comparatively modest.
Using experience gained during the development of the Alliance 2.0-litre dCi engine – and carrying over some technology – accelerated development of the new V6, but number of significant changes have been made to the hardware for the V9X. The combustion chamber design, for example, has been optimised to improve the balance between emission levels and fuel efficiency.
Changes at the rear of Pathfinder include a new bumper design with squared off edges to give a larger and lower mass for a more stable, tougher appearance.
