Tata Sierra Petrol Engine Variants Leak – 1.5L NA and Turbo Petrol Ka Pura Breakdown | EV Option Also Confirmed
Tata Motors’ iconic SUV – Tata Sierra – is once again in the headlines. This time the reason is its engine lineup which has now been officially revealed. Tata Motors will launch the new-generation Sierra with three different powertrain options – Petrol, Diesel, and Electric. But the most in the spotlight are the new petrol engine options, about which many new details have now been revealed.
🔥 Tata Sierra’s New Petrol Engine Strategy – 1.5L NA Confirmed
Tata has taken a bold move this time. Earlier it was expected that the lower variants of the Sierra would get Tata’s old 1.2L Naturally Aspirated (NA) petrol engine – but now a new 1.5L NA petrol engine is being introduced.
The exact power output of the new 1.5L petrol NA engine has not been officially confirmed yet, but this engine is a major part of Tata’s pricing strategy. Tata wants an aggressive starting price for the Sierra, and this engine will help achieve that goal.
As per rival comparison:
Model Engine Power Starting Price
Hyundai Creta 1.5L NA Petrol 115bhp ₹12.32 Lakh
Maruti Grand Vitara 1.5L NA Petrol 103bhp ₹11.42 Lakh
Tata Sierra (expected) 1.5L NA Petrol – (Not revealed) ₹11.50 – ₹12 Lakh (Expected)
If we compare with rivals, then Tata Sierra with its 1.5L NA engine will give direct competition to established models like Creta and Grand Vitara. And if the pricing is around ₹11.5 lakh, then it can definitely become a value-for-money option for buyers.
🏎️ Turbo Petrol Engine – Powerful Option, But Delayed
For those who want more performance, Tata has also planned for them. The top-end petrol variants of Sierra will get 1.5L Turbocharged Direct Injection Petrol Engine, which is already being used in Tata Harrier and Safari.
But there is a twist – this turbo engine will be slightly delayed in launch. Tata says that it wants to make the refinement and calibration of this engine perfect, so that the final product delivers high quality.
Engine Specs (Turbo Petrol):
Power: 170bhp @ 5,000rpm
Torque: 280Nm @ 2,000 – 3,500rpm
Transmission: Manual + Automatic options
This engine will be a solid upgrade for performance lovers, especially those who want a balance between power and torqu.
⚡ Tata Sierra EV – 500km+ Range Expectation
Apart from petrol and diesel, a fully electric version of Tata Sierra will also be launched – which will be the next big step in Tata’s EV strategy. According to reports, the Sierra EV will use the same 65kWh and 75kWh LFP battery packs that are seen in the recently launched Tata Harrier EV.
Harrier EV Battery Options:
65kWh: Single Motor, RWD
75kWh: Dual Motor, AWD
MIDC Claimed Range: 627km (RWD) and 622km (AWD)
The official range of the Tata Sierra EV has not been revealed yet, but it is expected that it will also offer 500km+ real-world range. The high-end trims will also get AWD (All-Wheel Drive) drivetrain, which will be a big plus point for off-road lovers.
🧠 Conclusion – Will Sierra Become a Segment Disruptor?
Tata Motors is clearly planning to disrupt a segment through Sierra. 3 powertrain options – NA petrol for budget buyers, Turbo petrol for enthusiasts, and Electric for future-focused users – this combination makes Sierra a highly versatile SUV.
If Tata keeps the pricing tight (as expected starting from ₹11.5 lakh – ₹12 lakh), then Sierra can give a serious challenge to not just Creta or Grand Vitara but many other players in the segment as well.
🚗 Final Verdict: Tata Sierra is ready to rule the Indian roads once again. With NA and Turbo petrol engines, and a promising electric variant, this SUV could become Tata’s next big blockbuster.
