The existing list of Sierra’s merits over its competitors was seemingly not significant enough for Tata as they have gone on to add a new milestone to its list of positives. In a certified run at NATRAX Indore, the Sierra was able to deliver an exceptional 29.9 kmpl, surpassing the previous national benchmark. The feat was executed by the Pixel Motion team, who drove the 1.5 L Hyperion Powered Sierra continuously from 7:00 AM to 7:00 PM on November 30th 2025. The record was officially validated the same day.
The sole reason behind such seamless performance was the presence of the 1.5L Hyperion Petrol Engine, engineered to deliver high efficiency without compromising refinement, performance and driveability. The car’s advanced combustion system and torque-rich performance band and friction-optimised architecture ensured consistent fuel delivery and stable performance throughout the run. The achievement stands as a testament to the engineering innovation and capability of the Hyperion Powertrain.
Speaking on the achievement, Mr. Mohan Savarkar, Chief Product Officer, said, “Setting a national efficiency record so early in the Sierra’s journey is a proud moment for us. The Hyperion engine platform was built to push the boundaries of what petrol powertrains can achieve, and this milestone validates that effort. It strengthens the Sierra’s value proposition for customers and underlines TMPV’s commitment to bringing advanced, efficient and future-ready technologies to the market.”
The Tata Sierra also achieved a top speed of 222 kmph at NATRAX, Indore under specified test conditions, demonstrating the performance capability of the 1.5L Hyperion engine in a parallel run.
