Do Tata Tiago is not good in hills area?

Tata offers the Tiago only with a 1.2-litre petrol engine (86PS/113Nm) mated to either a 5-speed manual or AMT. Though it is powerful enough for city usage, you might feel some lagging in sudden acceleration requirement and while overtaking at highway speed. Similarly, on hilly terrains you need to keep the car at a lower gear and higher rpm to get better output. It will do the job but it would be good option who like calm driving. Do take a test ride in order to get better clarity. Check out authorised dealership details.
