- 2014-2015 MU-X: 24.1 mpg average[1].
Manufacturer and independent road tests typically report fuel consumption in litres per 100 kilometres (L/100km):
- Manufacturer-claimed (2023, 3.0L diesel): 8.3L/100km (city/highway combined)[3].
- Independent testing has recorded real-world averages between 8.04L/100km and 8.65L/100km for the 3.0L engine, depending on conditions and load[3][6].
- Newer 1.9L diesel variant: Claimed 7.4L/100km (combined)[7].
The MU-X automatic diesel variant, as reported on Indian and Australian automotive sites, shows:
- ARAI (India) average: 13 km/l (about 7.7L/100km)[4].
- Real-world range: City mileage around 12 km/l; highway up to 14 km/l[4].
Tested results by reviewers:
- Testing by GoRV produced a real-world average of 8.04L/100km with a full tank delivering approximately 910 km of range under light load[6].
- CarExpert achieved 9.0L/100km (tested) vs. the claimed 7.4L/100km for a 1.9L variant[5].
Actual fuel efficiency will vary with driving style, load, tyre pressures, traffic, and weather, but most owners can expect between 8 and 9L/100km (about 26–31 mpg) in typical mixed driving[3][6].
