Powerful Performance: The 1.5L Turbo Petrol Engine
The newly launched Tata Sierra is equipped with a 1.5L turbo petrol engine that delivers a robust 160 PS of maximum power and 255 Nm of torque. This engine is paired with a smooth six-speed automatic transmission, ensuring an exhilarating driving experience.
Record-Breaking Endurance Run
On November 30, 2025, the Sierra participated in a certified endurance run at the NATRAX proving ground in Indore. The Pixel Motion team operated the vehicle continuously from 7 AM to 7 PM, only pausing briefly for driver changes. This rigorous test was validated by officials, securing the Sierra’s place in the India Book of Records.
Efficiency-First Engineering
Tata Motors emphasizes that the new 1.5-litre Hyperion turbocharged petrol engine is designed with an efficiency-first architecture. This engineering approach ensures optimal performance without compromising drivability or smoothness. The engine’s finely tuned combustion process and reduced internal friction enable it to maintain consistent performance throughout the endurance test.
Performance Beyond Fuel Efficiency
In addition to its fuel efficiency, the Sierra showcased impressive speed capabilities. During a controlled test at the same facility, the SUV reached a top speed of 222 km/h, demonstrating the performance potential of the Hyperion engine. However, Tata Motors has made it clear that customer vehicles will be electronically limited to a top speed of 190 km/h for safety reasons.
Safety First: Driving Guidelines
Tata Motors advises that both fuel efficiency and speed tests were conducted by trained professionals in regulated environments. The company strongly discourages owners from attempting to replicate these tests, emphasizing the importance of safety in everyday driving.
