The W10 automatic gives me a mileage of 4.5 km/litre. The last 10 times I have filled the tank of 70 litres it shows "Low" fuel at 300 km. The mileage screen is faulty, I think the lowest number on it is 9.
I complained to Mahindra many times, they got 5.5 km/litre by their own technicians, then did another test where they manipulated the test - chose roads with no traffic and no signals, filled more than the full to give a slighly better number.
EIther my vehicle is defective or the design of automatic engine is flawed. My complaints are brushed off by Mahindra. For a car of Rs. 20 lakhs, the returns are poor. A buyer should think more before investing.
