Tata Sierra Achieves 29.9km/l Mileage with 1.5L Hyperion Turbo Petrol Engine

The newly launched Tata Sierra, equipped with its potent 1.5-litre Hyperion turbo-petrol engine, has made it to the India Book of Records. How? The SUV achieved a remarkable 29.9km/l during a 12-hour certified run at the NATRAX facility in Indore, surpassing the previous national record and securing its place in history for attaining maximum fuel efficiency in that time frame. The Pixel Motion team carried out the continuous run from 7:00 AM to 7:00 PM on November 30, 2025, with only brief driver swaps, and the record was officially verified the same day.

Commenting on the milestone, Mohan Savarkar, Chief Product Officer, Tata Motors Passenger Vehicles, 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.'
