Entry-level Tata Sierra expected to be equipped with the new 1.5 NA petrol engine.
The new naturally aspirated 1.5-litre engine, likely a derivative of the direct-injection turbo unit, is expected to be used on entry-level Sierra variants, providing buyers with an aggressive starting price and the same options as Korean rivals. The Hyundai Creta and Kia Seltos are on sale with 115hp, 1.5-litre petrol and 160hp, 1.5-litre turbo-petrol engine options. The Grand Vitara also comes with a 103hp, 1.5-litre naturally aspirated petrol engine on entry-level variants.
Higher petrol variants of the Sierra will be powered by the 1.5-litre direct injection turbocharged unit seen at Auto Expo 2023. At the motor show, the engine on display was said to produce 170hp and 280Nm, though a different state of tune may be offered on the Sierra.
