Tatas need to re-design the gear box for proper acceleration and pickup in AC mode. Should make rust-proof total ABS body. Should pay proper attention to stagnant water seepage pockets inside the doors. I increased the tyre size to 175/70 and got extra 10% mileage. This size of tyres should be standard fitment. Tatas should pay some more attention to user friendly electricals and other consumables... e.g. if the wiper arm rubber wears off, we have to change the entire wiper arm and no loose rubbers for wipers are available. The electrical contacts wear off very fast - due to excessive heating.. apparently the economy in manufacture is doing this... - and we have to change the full set to remedy... but we land up with the same old defective manufacture... mismatching in the load and contacts capacityExcellent fuel economy on diesel. I got over 25 KM/Ltr. on long drive - 500+ KMs. Very comfortableSudden braking in accidental conditions leaves much to be desired
