Tata Motors is making a strong statement in the SUV market with two compelling products—the Tata Sierra and the Tata Curvv. Both vehicles share similar underpinnings and diesel powertrains, yet they offer completely different driving experiences and target audiences.
For buyers considering diesel-automatic SUVs, the comparison becomes even more interesting. While both models use a 1.5-litre diesel engine, differences in tuning, transmission, and overall character set them apart.
So, which one performs better in real-world conditions? Let’s break it down in detail.
Engine & Powertrain: Same Base, Different Personality
Both the Tata Sierra and Tata Curvv are powered by a 1.5-litre turbocharged diesel engine.
Key Engine Specs:
- Power: Around 116–118 hp
- Engine capacity: 1497 cc
- Turbocharged diesel setup
However, the real difference lies in torque output and transmission.
- Tata Sierra: Around 280 Nm torque
- Tata Curvv: Around 260 Nm torque
This gives the Sierra a slight advantage in pulling power, especially under load.
Transmission Difference: The Real Game Changer
The biggest distinction between these two SUVs lies in their automatic gearbox setup.
Tata Sierra Diesel Automatic
- Torque converter automatic
- Smooth and relaxed driving experience
- Better suited for city traffic and comfort driving
Tata Curvv Diesel Automatic
- Dual-clutch transmission (DCT)
- Faster gear shifts
- Sportier driving feel
What This Means in Real Life:
- Sierra feels more refined and effortless
- Curvv feels quicker and more engaging
Your choice depends on whether you prioritize comfort or performance.
Acceleration & Driving Feel
Tata Curvv
- Quicker off the line due to DCT
- More responsive throttle

However, the difference is not significant.
Weight & Size Impact on Performance

Again, the difference comes down to comfort vs sportiness.
