New Tata Sierra Test Unit Spotted; Seems to be a CNG or AWD Version

The Tata Sierra continues to stay in the spotlight, even after its recent market debut. While the SUV has already started reaching customers and clocking impressive sales, Tata Motors seems far from done with its development cycle.

A newly spotted test mule of the Sierra, heavily camouflaged, has reignited curiosity. Interestingly, this prototype features a visible cutout for an exhaust outlet - strongly indicating that this is not the electric version, but rather an internal combustion (ICE) derivative undergoing testing.

Tata Sierra: What Does the New Test Mule Indicate?

The presence of an exhaust cutout points toward a petrol-powered version, but what's more intriguing is why Tata is testing it again. The latest sighting suggests that the company could be working on either a CNG-powered Sierra, an AWD (All-Wheel Drive) variant, or possibly both.

Earlier, Tata Motors had hinted at expanding the Sierra lineup depending on customer demand. Given the SUV's strong market response so far, it seems the brand may now be actively exploring these additional configurations.

Tata Sierra: Strong Market Demand Driving Expansion

The Sierra has quickly gained traction in the competitive mid-size SUV segment. With strong booking numbers and growing demand, Tata is reportedly scaling up production.

This kind of response often pushes automakers to diversify their offeringsand in this case, both CNG and AWD options make strong business sense.

Sierra CNG: Practical and Cost-Effective?

If Tata proceeds with a CNG version, it is expected to prioritize efficiency and lower running costs. The SUV could feature a dual-cylinder CNG setup, similar to other Tata i-CNG models, ensuring that boot space remains usable along with a spare wheel - something many rivals compromise on.

Under the hood, the CNG variant is likely to be paired with a 1.5-litre naturally aspirated petrol engine, which currently produces 106 bhp and 145 Nm in standard form. Theres also a possibility of Tata offering an automatic gearbox with CNG - something that could make it a segment-first proposition.

Sierra AWD: Adding Capability

On the other hand, an AWD version would cater to enthusiasts looking for better traction and versatility. This variant is expected to be offered with a more powerful engine option, potentially the 1.5-litre Hyperion turbo-petrol unit, paired with a torque converter automatic transmission.

An AWD-equipped Sierra would directly challenge rivals offering similar drivetrains, especially in lifestyle and adventure-focused segments.

Tata Sierra: Competition Insight

Rivals like the Maruti Suzuki Grand Vitara and Toyota Urban Cruiser Hyryder already offer buyers the flexibility of choosing between CNG and AWD configurations (though not together). If Tata brings both options to the Sierra lineup, it could significantly strengthen its position in this space.
