Europe’s best SUV and brother of sales since its launch – Nissan Navara and Nissan Pathfinder – have been given the medium term drive to several major improvements to keep on top.
Among the changes was the arrival of a new and technically sophisticated 3.0-liter V6 diesel, diesel popular DCI significant improvement of 2.5 liters, more passive safety levels, new equipment, including the availability of prior art track system Nissan Connect Premium touchscreen satellite, navigation through the Bose sound system and a rear view camera, improved interior quality and some style changes to keep the Nissan Pathfinder and Navara looks strong.
Nissan reinforce improvements along key positions in the market for all-wheel drive and enhance the Nissan Navara and Pathfinder in the state of a highly competitive segment.
Presented at the Geneva Motor Show, who improved new look Nissan Navara and Pathfinder models on sale across Europe in April 2010. They will be followed two months later by a new 3.0-liter V6 diesel flagship.
The new V6 diesel engine
The new V6 direct injection turbodiesel has been developed by Renault-Nissan alliance to provide a high level of performance with a strong, competitive and class-leading emissions improvements.
The key elements of the new V6 – V angle of the unusual 65 degrees – is the material chosen for the engine block. The development engineers chose Alliance compacted graphite iron (CGI), a material that offers all the benefits of cast iron, including a high level of rigidity and noise absorption without severe penalties. And while the CGI is heavier than the pure alloy block is not necessary to increase the stiffness of the rib cage or mute the sound so that the weight gain of additional material is relatively simple.
Using the experience gained during the development of the Alliance Division 2.0-liter engine – and brings more than a few technologies – accelerating the development of the new V6, but some significant changes have been made to the hardware to V9X. Design of the combustion chamber, for example, is optimized to improve the balance between level of emissions and fuel efficiency.
Compression ratio fell to 16:1 not only benefits the economy and emissions, but also sound, vibration and harshness (NVH), while the internal engine friction is reduced with the use of ultra-thin components, such as micro-finished forged steel crankshaft is used.
The main categories of torque and is very competitive, specific power by adopting sent a relatively large single turbo, which is mounted on the V engine, an intercooler, and the use of the latest generation Bosch common-rail injection . This system combines piezo injectors and operates at 1800 bar.
Power output is 170 kW (231PS) while the output torque of 550 Nm at leading the class. Better yet, reached the maximum torque from as low as 1700 rpm and is available all the way to 2,500 rpm, while close to 500 Nm from just 1500 rpm. Idle speed is very low, 650 rpm without vibration and noise usually associated with diesel.
The result is a strong low-end performance with a comfortable and improve the delivery of throttle response is exemplary. In addition, the traction machine helps to give a strong performance, Nissan Pathfinder trailer capable of towing a 3500 kg braked with Nissan Navara has a limit of 3,000 kg.
The emissions and energy efficiency objectives, including compliance with Euro 5. In addition to the achievements of the change in the combustion chamber, which also V9X machine incorporates a number of innovative features.
These include the adoption of overcooled gas recirculation (EGR) to reduce NOx emissions. The integrated system combines the exhaust gases to prevent rapid cooling of EGR helps to achieve the optimal temperature after the launch so that the full cooling capacity can be used. This feature of low temperature for cooling water recirculation circuit to further reduce the temperature of exhaust gas and reduces carbon monoxide and hydro carbon emissions.
Equally important is the treatment of exhaust emissions. The system consists of an oxidation catalytic converter metal provides a lower pressure loss to the system and catalytic exothermic ceramic catalyst and diesel particulate filter (DPF) in the same container. Final arrangements in collaboration with seven fuel injection located in the exhaust.
This is activated while the particulate filter is regenerated – a process that drivers did not notice – but it means a great opportunity to burn polluting fuels the engine oil has been removed. It also allows the filter to be regenerated at low load conditions such as idling, and therefore achieve a high level of efficiency in all driving conditions. This also helps to stretch the oil change intervals to 20,000 km.
Improved four-cylinder 2.5 dCi
Existing four-cylinder 2.5 dCi not forget, however, and significant improvements to strengthen its position as the most popular machines in the range, with good improvements and overall improvement of all aspects of performance.
Subtle useful retuning has seen an increase of 11 percent in power and torque to keep the engine at the top of the class. Increased power of 19 PS to 140 kW (190 PS), while torque increased by 47 healthy Nm to 450 Nm.
And provide performance benefits, the changes that have seen the fuel economy and lower emissions. In the manual version of the combined cycle from 8.5l/100kms – an increase of 1.3 l/100kms – while CO2 emissions are reduced by 40g/km and 224 g / km.
The revised model has been given a new look front and rear to distinguish them from their predecessors. Changes in the front of the CAP, including the new, revised grille and new bumper assembly. Add 80 mm to the length of the two models, the bumper is more rounded and more sports to give finishing touches to the car.
There is a new design of the projector headlights with distinctive style, where xenon lights installed (Nissan Pathfinder only). Wash the headlights now a pop-up from the bottom is formed in the body color bumper. There is a new 18-inch alloy wheels to complement the existing range of 16 inches (steel alloy) and 17 inches (alloy) design. V6 models, meanwhile, was given in secret V6 badges on the cutting edge of the front door while the V6 Nissan Pathfinder also gets a molding of New face at the door.
Changes to the rear of the Nissan Pathfinder, including a redesigned front bumper with an edge of the plaza to provide greater mass and lower the more stable, more resilient appearance.
The color palette is modified to include two new metallic colors for Nissan Navara – electric blue and Blue Gray – Blue gray, while portfolio is added to the Nissan Pathfinder.
Most of the changes in the second car, Nissan Navara and Pathfinder is designed to improve the quality and includes a new switch, revised decorations on the doors, cloth seats again, adding touches of chrome, reviewed quickly and, depending on model, availability of Nissan Connect Premium with the new high-resolution touch screen.
Typical of the attention to detail that has helped improve the quality of the doors has been modified to improve both the appearance of the interior and practicality. Cushion chair and the door is more tactile to the touch and form have also been modified to make them more comfortable to wear.
And to improve fit and finish, materials used have also been improved. He plays practical means of storage of waste can now be happy to celebrate the map Book A3 and a liter bottle. Tray storage in the door is now large enough to accommodate a standard Nissan first aid kit.
Switches changes include a new and easier to use, allowing traction control command while Nissan Pathfinder steering wheel controls for the phone and the audio is now illuminated. Chrome finish are added to surround and automatic transmissions, depending on the model class for the table of the instruments. There is a new table in the center console storage with lid damping, while the SE and LE also benefit from “Fine Vision Meters call ‘with a clean look. Nissan Pathfinder LE version now has a choice of cake black or light leather upholstery.
Repair equipment, including new speed limiter, which belong to the cruise control system that already exists.
Increased active safety with the availability of Nissan’s electronic stability program (ESP) in the Nissan Navara (already available in the Pathfinder) that uses sensors to monitor the engine ECU, wheel speed, steering angle, longitudinal and lateral plus G and yaw to predict and control wheel slip.
Premium Nissan Connect, the brand integrated navigation, communication and music system optional extra. Simple and quick to use, 40GB hard drive, has a touch screen system based on high-resolution 3D maps and bird’s eye view, while expanding coverage to Russia, Turkey and Eastern Europe. New multi-function controller is installed and intuitive system also features RDS-TMS live traffic updates and rich content of the Michelin.
There are eight languages available for the menu and the navigation system while the voice recognition software can handle seven: English, French, German, Italian, Spanish, Portuguese and Dutch. Optional available is a Bose sound system with premium speakers and amplifier specifically designed for the Nissan Navara and Pathfinder.New computer is behind the camera view. Already available in the Nissan Pathfinder, now it can be determined in the Nissan Navara, which offers better visibility when parking, especially when the cargo bed or a hardtop installed
