Mahindra Auto launched the XUV7XO earlier this year and it was the first big mainstream launch for the calendar year 2026. We got a major interior overhaul and an exterior design refresh with the XUV7XO compared to the XUV700. However, the powertrains are the same as what the XUV700 offered.
The same 2.0 liter turbo petrol with a headline figure of 200 PS of maximum power and a 2.2 liter turbo diesel engine with a headline figure of up to 450 Nm continues with the Mahindra XUV7XO. However, we experienced the diesel automatic AWD variant for the first time in a long time and we decided to do a mileage test report based on our observations during about 1,500 km of testing.
Mahindra XUV7XO Mileage Test Report
After experiencing the
One test was done in the D gear of the 6-speed torque converter and the other test was done in manual mode where I took charge and tried to upshift as quickly as I could to see if I could hypermile to extract maximum fuel efficiency figures. The goal was to test whether one could comfortably get 1,000 km of range from the XUV7XO’s 65L fuel tank.
first mileage run
In the first full tank example, the XUV7XO’s instrument cluster showed an estimated range (distance from empty bar) of 999 km, which was the maximum possible figure. This was quite impressive initially and as I covered more and more kilometers in the
Trip B was reset to ‘0’ and the journey started with some city driving from Pune and then onto the National Highway towards Karnataka via Satara. At the 383.9 km mark on Trip B, our media fleet vehicle XUV7XO diesel automatic AWD was refueled and at that time, the instrument cluster was showing fuel efficiency numbers of 14.2 km/l.
The SUV took 27.27L diesel to fill the 65L tank at the same place as before and with this fuel, a total distance of 383.9 km was covered. This yielded a real world mileage (fuel efficiency) of 14.08 km/l with the tank-to-tank method, which was close to what was being shown on the instrument cluster. It should be noted that the XUV7XO gearbox was in D gear at all times and gear shifts occurred automatically on a pre-determined algorithm.
With a mileage figure of 14.08 km/l, the XUV7XO diesel automatic AWD offers a tank range of around 900 km. It should be noted that the SUV was being driven quite slowly and if driven aggressively, the fuel efficiency would go down further and even fall into the single-digit region. XUV7XO Diesel with Automatic AWD One cannot easily drive 1,000 km on a single tank of 65L diesel.
second mileage run
One would think that for a vehicle of its size, 14.08 km/l is not a bad figure. However, we drove the diesel manual FWD combination at the XUV7XO launch and media drive event in Jaisalmer and this diesel manual in the XUV700 has a proven track record of impressive mileage. So, we knew that the XUV7XO diesel was capable of delivering much higher fuel efficiency in D gear than our diesel auto AWD.
So, I refilled the tank and did another mileage run. This time, the XUV7XO 6-speed automatic gearbox was in manual mode with Tiptronic function and I upshifted as quickly as possible to achieve hypermiles and maximum fuel efficiency. When we filled the SUV again, we realized that the fuel efficiency was only slightly better at 14.2 kmpl. Some would say it is virtually identical.
mileage test results
* Run 1 (D mode): 14.08 km/l
* Run 2 (Manual Mode): 14.20 km/l
* Improvement: 0.12 km/l
* Estimated range: ~900 km at slow speed
* Estimated range: ~750 km at highway speeds
* Target 1,000 km range: not achieved
6-speed torque converter
One of the contributing factors to this low mileage figure is the AWD hardware which adds some weight to the overall package. But the main contributor is Mahindra’s 6-speed torque converter automatic gearbox and how it is tuned to operate. It has the ability to ride the wave of torque from the XUV7XO diesel and extract as much fuel efficiency as possible.
This gearbox keeps the engine boiling all the time and does not allow it to refuel in higher gears. Even in manual mode, the pre-set minimum speed criteria where this torque converter upshifts remains the same as when it was shifting automatically in D mode. These minimum speeds are 30 km/h for 2nd to 3rd, 45 km/h for 3rd to 4th, 67 km/h for 4th to 5th and 83 km/h for 5th to 6th.
All these speeds are quite high for those respective gears, considering that the Mahindra XUV7XO diesel is powered by a 2.2L turbo diesel engine, which produces up to 450 Nm of peak torque. Whether you are in D mode or manual, this gearbox does not upshift below these speeds, even if you have taken command and upshifted manually. This engine has a lot of torque and has exceptional tractability. But this gearbox keeps it boiling and doesn’t let it cool down in higher gears.
Manual is more efficient!
For reference, the 110 PS Renault K9K diesel engine allows me to upshift to 6th gear in under 60 km/h without any hesitation. It even stops recommending downshifting to 5th gear at 65 km/h. But in the
There were very few instances when I could switch to sixth gear at speeds above 83 km/h. On normal Indian roads, state highways and even national highways, random things keep happening and one always has to slow down or apply brakes frequently. When this happens, the XUV7XO diesel automatic AWD variant we have immediately shifts to fourth gear or sometimes even third gear, leaving the engine boiling.
Even though the Mahindra XUV7XO has great refinement, this 2.2L diesel engine is very loud and audible inside the cabin. Keeping the engine boiling adds a level of raunchiness that complicates the overall experience of an otherwise impeccable package. We would have liked Mahindra to lower these minimum speed constraints for the diesel automatic variants to allow the driver to have more control over shifts.
If you’re a driver-owner who wants driving ease and off-road capability at the expense of fuel efficiency, the diesel auto AWD makes a lot of sense in the XUV7XO’s variant lineup. If you want to go 1,000 km on a tank at normal highway speeds or own a chauffeur-driven vehicle, the diesel manual may prove to be a better option.
