Tata Sierra to Get Dual Petrol Engine Options — 1.5L NA for Lower Variants

Tata Sierra EV: All you need to know about the Sierra!

Tata Motors is gearing up to make a bold return with the iconic Tata Sierra, and now there’s a new twist to the tale. The upcoming ICE version of the Sierra SUV will debut two all-new 1.5-litre petrol engines — a naturally-aspirated unit for the lower variants, and a direct-injection turbocharged version for the higher trims.

This strategic move will allow Tata to price the new Sierra competitively, pitting it directly against segment leaders like the Hyundai Creta and Kia Seltos, both of which also offer dual petrol powertrains.
