The upgrade covers both the 190bhp twin-turbo and 160bhp single turbo versions of the engine, and CO2 emissions are now as low as 159g/km – a reduction of 8g/km on the previous Euro 5 engine.
Fuel consumption on the official combined cycle has improved to 46.3mpg – up by 1.4mpg – and Nissan has fitted its idle-stop system as standard on all manual models.
The AdBlue tank has a filler flap on the opposite side of the vehicle to the diesel tank to avoid confusion. The tank can be filled from bottles or pumps, and holds 17 litres of liquid, allowing up to 7,150 miles between refills.
Depending on the model, the gvw has increased by 25kg-35kg, while kerb weight has increased from 5kg-38kg.
Driver assistance messages relating to the AdBlue system have been integrated into the Navara’s colour LCD combimeter, the central information screen set between the two main dials. All Navara models now come with a colour combimeter, cruise control, Bluetooth hands-free audio and multi-function conrols on the steering wheel.
The Navara comes with a five-year/100,000-mile warranty.
