⛰️ OFF-ROAD & ECONOMY READY: Tata Sierra AWD and CNG Variants Confirmed—Launch By 2027
Following the massive launch success of the new-generation Tata Sierra, Tata Motors has officially confirmed its aggressive plans to diversify the SUV’s lineup with two crucial additions: an All-Wheel Drive (AWD) version and a highly-anticipated CNG variant.
These new variants are key to Tata’s strategy of maximizing the versatility of the Sierra’s ARGOS platform (All-terrain Ready, Omni-Energy, and Geometry Scalable Architecture), catering to both the off-road enthusiast and the cost-conscious daily commuter.
🏔️ Sierra AWD: Bringing Back the Off-Road Legacy
The original Tata Sierra was India’s first indigenous lifestyle SUV and was famously offered with 4×4. The new AWD variant will revive this heritage, providing enhanced traction and capability that aligns with the SUV’s rugged design.

| Platform Capability | ARGOS Architecture is AWD-ready | The platform was specifically engineered for this feature. |
| ICE AWD Launch | Early 2027 | Confirmed by Tata Motors’ CCO to meet increasing consumer demand for capable SUVs. |
| EV AWD Launch | Early 2026 | The fully-electric Sierra EV is expected to debut the AWD system first, likely mirroring the Harrier EV’s AWD setup. |
| Expected Engine | Likely paired with the 1.5-litre Turbo-Petrol ($160 \text{ hp}$) and 1.5-litre Turbo-Diesel ($118 \text{ hp}$) options. | Ensures sufficient power output for genuine off-roading. |

Official View: Tata Motors’ Chief Commercial Officer, Vivek Srivatsa, stated that the AWD system was prioritized due to the growing consumer need for enhanced capability and the strong performance of AWD variants in models like the Harrier EV.
⛽ Sierra CNG: Economical Powerhouse
The planned CNG variant aims to deliver a significantly lower running cost, utilizing Tata’s successful ‘iCNG’ technology, which has driven sales in their smaller models (Punch, Tiago, etc.).
| CNG Variant Detail | Expected Technology / Feature | Buyer Benefit |
| CNG Technology | Expected to use Twin-Cylinder iCNG | Preserves most of the Sierra’s massive $622 \text{ Litres}$ boot space. |
| Launch Dependent On | Market Demand | Tata has confirmed the variant is developed and ready but will launch based on sustained consumer interest in the $4 \text{ metre}$ plus CNG segment. |
| Base Engine | Likely based on the 1.5-litre Naturally Aspirated Petrol ($106 \text{ hp}$) | Offers maximum efficiency, targeting city and economy buyers. |
| Expected Running Cost | Anticipated to be $50\% – 60\%$ lower than the petrol variant. |
➡️ Expanding the Sierra Family: EV and 7-Seater
The AWD and CNG additions are part of a broader strategy to make the Sierra a comprehensive SUV line-up, providing a solution for every kind of customer.
| Variant | Projected Launch Timeline | Key Feature |
| Sierra EV | Early 2026 | Expected to have $\approx 550 \text{ km}$ range and debut the AWD electric system. |
| Sierra 7-Seater | Under Consideration (Post-2027) | Platform is ready; launch hinges on market response to the 5-seater model. |
