Power Lag (Week Engine)

I am writing my review after around 9 months use. I have bought this Car due to its Safety Rating and I am impressed about the Build Quality and stylish Look. Riding Quality is Good you will feel stable at cornering (Don't try to do this). But i m very much disappointed due to the engine power. It struggle even on first gear if you are at bit upward road, thud sound with vibration is coming from the engine, I felt that I am driving a week car in terms of pick up and power. This is the only one thing and which is big thing for me that Altroz is under power Car. Tata should have provide either 4 cylinder or more torque to engine. Apart from engine and its power lag issue it will Gives you premium feel, Good Space, Good Sound System, Good Suspension, Good Mileage (around 19-20 on highway and 13-14 in City with Normal AC Use), Much more Features and Safe Feel when you are driving the Car.
