Does the Tata Sierra’s naturally aspirated petrol engine feel underpowered?

Yes, the 1.5-litre naturally aspirated petrol engine can feel underpowered, especially considering the Sierra's size and weight. It is suitable for daily city driving. However, with four or five passengers and luggage onboard, you'll need to work the engine harder during highway overtakes or steep climbs. Buyers who frequently travel on highways or prefer stronger acceleration should consider the turbo-petrol or diesel variants instead.
