Tata Sierra test mule spotted for CNG and AWD variants before 2027 Launch

Tata Motors continues to test the Sierra SUV, despite its recent launch in India. The latest test mule, seen with full camouflage and an exhaust tailpipe cutout, suggests the company is developing an internal combustion engine variant. This points to possible CNG or all-wheel-drive (AWD) versions, both of which Tata Motors has previously discussed.

Key Highlights

• Tata Sierra test mule spotted with exhaust cutout indicating ICE variant in development
• Sierra became fifth best-selling C-segment SUV with 7100 units sold in February 2026
• Tata Motors has over 1 lakh bookings for the Sierra and is ramping up production
• CNG and AWD variants under consideration with possible launch in early 2027
• Sierra CNG may feature 1.5L petrol engine and 7DCT gearbox option

Current Sierra Performance and Demand

Tata Motors began deliveries of the Tata Sierra at the start of 2026. The SUV quickly became the fifth best-selling model in the C-segment SUV category, which includes vehicles between 4.2 and 4.5 meters in length. In February 2026 alone, Tata sold 7,100 units of the Sierra. The company has received over 100,000 bookings, prompting increased production at its facilities to meet demand.

When unveiling the Sierra, Tata Motors announced readiness to introduce both AWD and CNG variants if there was sufficient market interest. The company has already developed and validated a CNG option internally. Tata continues to monitor customer feedback and segment trends to determine the right time for launching these variants.

Potential CNG and AWD Variants

Recent sightings of test mules indicate Tata Motors may have approved development of the Sierra CNG and Sierra AWD. In the C-segment SUV space, competitors like Maruti Suzuki and Toyota offer models such as the Grand Vitara, Hyryder, and Victoris with either CNG or AWD options, but not both in the same vehicle.

If Tata proceeds, the Sierra CNG will likely feature a dual-cylinder CNG tank setup. This approach is similar to other Tata i-CNG vehicles and includes a spare wheel, which some competitors like Maruti's Victoris lack due to underbody CNG tank placement. The Sierra CNG aims to provide improved fuel efficiency and lower running costs for buyers.

Tata is expected to offer the Sierra CNG only with a 1.5-liter naturally aspirated petrol engine. This engine produces 106 bhp and 145 Nm of torque on petrol. The company may also introduce a 7-speed dual-clutch transmission (7DCT) for the CNG variant, which would make it the first automatic CNG SUV in this segment.

For the AWD version, Tata Motors may equip the Sierra with a 1.5-liter Hyperion engine and a 6-speed torque-converter automatic gearbox. These features would target buyers seeking enhanced traction and performance.

Expected Launch Timeline

No official launch date has been announced for the Sierra CNG or Sierra AWD. However, market speculation suggests that early 2027 could be a likely timeframe for their introduction. Tata Motors continues to assess market feedback and competitor offerings to determine the best strategy for these variants.

Conclusion

The spotted Tata Sierra test mules signal exciting expansions with CNG for cost-conscious commuters and AWD for adventure seekers, built on the flexible ARGOS platform. As production ramps up amid surging sales, these variants promise to solidify Sierra's dominance in India's mid-size SUV segment by 2027.
