I would have loved auto transmission like the maruti provides in its hatchback . It goes upto 120 km without any issues and pick up is awesome. AC is very powerful.door locking nobs on window is orthodox.change 2nd gear to 3rd gear at a speed of 40 then, engine starts vibrating and give a noisy sound.Though there is no vibration in the car.Tata cabins have always been roomy.The Tiago gets the 1.2-litre three cylinder Revotron engine that develops 84bhp of power at 6000rpm and 114Nm of torque. The 1.05-litre turbocharged diesel mill churns out 70bhp of power and 140Nm of torque from 1800rpm.
