The RTI Disclosure: Engine-Wise Mileage Breakdown

Now the official efficiency figures have moved from rumors to reality. An RTI query recently accessed by social media user Vahan Warta has confirmed the Automotive Research Association of India (ARAI) data. Therefore, the Sierra’s performance on paper is now transparent for all three main powertrains.

First, the 1.5-litre TGDi Hyperion turbo-petrol delivers 13.5 kmpl. Next, the 1.5-litre Kryojet diesel emerges as the efficiency leader at 18.8 kmpl. Thus, the diesel variant remains the preferred choice for long-distance commuters. However, the 1.5-litre naturally aspirated petrol variant is still awaiting its final ARAI certification.

Performance Specs: Hyperion vs. Kryojet

Now the Sierra isn’t just about efficiency; it’s a powerhouse in its segment. Therefore, Tata Motors has equipped the SUV with its most advanced “Next-Gen” engine lineup.

• 1.5L TGDi Hyperion: Produces 160bhp and 255Nm of torque. It comes exclusively with a 6-speed automatic.

• 1.5L Kryojet Diesel: Offers 118bhp and up to 280Nm. It is available in both 6-speed manual and automatic versions.

First, the Hyperion engine targets enthusiasts looking for punchy acceleration. Next, the Kryojet focuses on torque-heavy performance for highway cruising. Thus, the Sierra caters to a wide spectrum of Indian drivers.

Delivery Update: 10,000 Units and Counting

Now the “Sierra Fever” is reflecting in the actual sales numbers. Deliveries officially commenced on January 15, 2026. Therefore, the SUV has already made a significant dent in the mid-size SUV market within just a few weeks.

First, Tata Motors confirmed that over 10,000 units have already been handed over to customers. Next, the company is ramping up the Sanand manufacturing lines, which the Sierra shares with the popular Tata Nexon. Thus, monthly production is expected to hit 15,000 units soon to reduce the waiting periods that currently stretch into several months.

What’s Next: The Sierra EV and AWD Roadmap

Now the current lineup is only the beginning of the Sierra’s journey. Therefore, Tata Motors is preparing to leverage the “ARGOS” platform for more adventurous variants.

First, an All-Wheel-Drive (AWD) version is in the pipeline to offer genuine off-road capability. Next, the highly anticipated Sierra EV is slated for a mid-2026 launch. Thus, the brand aims to dominate both the internal combustion and electric SUV segments by the end of the year.

Also, the 1.5-litre naturally aspirated Revotron variant will likely receive its mileage certification before the festive season, providing a budget-friendly entry point for city buyers.
