Entry-level NA petrol to target price-conscious buyers

The new 1.5-litre naturally aspirated engine will help keep the Sierra’s starting price competitive, enabling Tata to rival the lower variants of the Creta, Seltos, Elevate, Grand Vitara, Hyryder, and Astor in the midsize SUV segment.

Turbo petrol for higher trims

The 1.5-litre T-GDI turbo petrol engine is aimed at higher variants, ready to compete directly with turbocharged rivals from Hyundai and Kia. It is expected to offer performance and refinement upgrades, and will also be used in the upcoming Harrier and Safari petrol models.
