The Nissan Navara 2.3 diesel typically achieves a real-world average fuel consumption of around 8.5L/100km, which translates to approximately 33.2 mpg (imperial)[1]. Officially, Nissan claims combined economy figures of up to 40.4mpg for the 2.3-litre diesel in various configurations, with automatic four-wheel-drive Double Cab models returning up to 38.2mpg[4]. In practice, actual user figures tend to be lower, with long-term test reports and owner calculations often ranging between 31-35mpg[3][5].
Specific consumption figures for different Navara 2.3 versions:
- 2.3D Double Cab, Automatic (real-world): about 8.5L/100km (33.2mpg)[1]
- 2.3D King Cab AWD (official): 6.4L/100km (44.1mpg UK, 36.7mpg US)[6]
- Four-wheel-drive Double Cab Automatic (official): 38.2mpg, 194g/km CO₂[4]
- All 2.3 diesel variants: Claimed range 38.2–46.3mpg depending on configuration; real-world averages tend to be 32–35mpg[2][5]
Owners report that the on-board computer can sometimes be optimistic, showing figures 10–20% better than what is observed by manual calculation[3]. Factors such as driving style, terrain, and load can affect the actual fuel consumption, and high consumption of AdBlue (urea solution for emissions control) might increase running costs slightly[2].
