The Isuzu MU-X 1.9L turbo-diesel is designed for fuel efficiency, with an official combined cycle fuel consumption claim of 7.4L/100km for both the 4×2 and 4×4 models[1][2][3][4][5]. Real-world testing confirms these figures to be largely accurate, with observed consumption typically ranging from 7.4L/100km to 8.2L/100km in highway driving[1][6]. Around town or under heavier load (such as towing), fuel consumption increases, but for normal usage, the 1.9L engine stands out for its relatively low fuel use among large SUVs.
Here are key fuel consumption numbers for the Isuzu MU-X 1.9:
- Official combined cycle fuel consumption: 7.4L/100km (both 4×2 and 4×4)
- Urban cycle: 9.0L/100km
- Extra urban/highway cycle: 6.7L/100km
- Observed highway consumption: 8.2L/100km (with people and luggage)[1]
- Observed around town: Figures may run higher than combined; expect 9.0L/100km or more with urban driving[1][6]
- Towing (notably a 2100kg caravan): Around 15.1L/100km[4]
- Fuel tank capacity: 80 litres, giving a theoretical combined range of about 1080km[2]
Compared to the larger 3.0L MU-X engine, the 1.9L variant provides a modest but meaningful advantage in fuel efficiency—about 0.9L/100km less on the combined cycle—without any claimed penalty when opting for four-wheel drive[2][3][4][5]. For buyers seeking a large SUV that balances space and capability with lower running costs, the 1.9L option is positioned as the efficient choice, though it is less powerful and less suited to heavy towing than the 3.0L alternative[3][4][5].
