Let’s compare their mileage, performance, and cost-effectiveness to guide your purchase decision in 2025.
Tata Punch Petrol vs CNG: Specifications
| Specification | Tata Punch Petrol | Tata Punch CNG |
|---|---|---|
| Engine | 1.2L Revotron, 3-cylinder | 1.2L Revotron, 3-cylinder |
| Power | 84.82 bhp @ 6000 rpm | 72.41 bhp @ 6000 rpm |
| Torque | 113 Nm @ 3300 rpm | 103 Nm @ 3250 rpm |
| Transmission | 5-speed Manual, 5-speed AMT | 5-speed Manual, 5-speed AMT |

| Boot Space | 366 Litres | 210 Litres (twin-cylinder) |
| Ground Clearance | 187 mm | 187 mm |
- Petrol: Offers higher power and torque, making it slightly more responsive, especially on highways. The larger boot space (366L) is ideal for families needing extra cargo room.
- CNG: Slightly lower power output but optimized for fuel efficiency. The twin-cylinder setup ensures 210L of usable boot space, better than traditional CNG vehicles.
Mileage Comparison: ARAI and Real-World Figures
Tata Punch Petrol Mileage
- ARAI-Certified:
- Manual: 20.09 kmpl
- AMT: 18.8 kmpl
- Real-World (based on user reports and tests):
- City: 15–17 kmpl
- Highway: 18–23 kmpl
The petrol variant’s mileage varies significantly based on driving conditions. In city traffic with frequent stops, users report 15–16 kmpl, while highway cruising at steady speeds (80–100 kmph) can yield up to 23 kmpl, especially with cruise control on AMT variants.
Tata Punch CNG Mileage
- ARAI-Certified: 26.99 km/kg
- Real-World (based on user and Autocar India tests):
- City: 20–22 km/kg
- Highway: 25–31 km/kg
The CNG variant excels in fuel efficiency, with real-world tests showing 20.7 km/kg in city conditions and an impressive 31 km/kg on highways. Users report 27–28 km/kg in mixed conditions, making it a cost-effective choice for high-mileage drivers.
Verdict: The Punch CNG offers significantly better mileage (26.99 km/kg vs 20.09 kmpl for petrol manual), making it ideal for those prioritizing fuel savings. Petrol variants perform better in low-traffic highway scenarios but lag in city efficiency.
Running Cost Comparison (Delhi, 2025)
To understand the cost-effectiveness, let’s calculate the running costs based on approximate fuel prices in Delhi (as of June 2025):
- Petrol: ₹100/litre
- CNG: ₹75/kg
| Variant | Mileage (Real-World) | Cost per km | Monthly Cost (300 km) |
|---|---|---|---|
| Punch Petrol Manual | 17 kmpl (mixed) | ₹5.88 | ₹1,764 |
| Punch Petrol AMT | 16 kmpl (mixed) | ₹6.25 | ₹1,875 |
| Punch CNG | 25 km/kg (mixed) | ₹3.00 | ₹900 |
- Petrol Manual: At 17 kmpl, it costs ₹5.88/km, leading to ₹1,764/month for 300 km.
- Petrol AMT: At 16 kmpl, it costs ₹6.25/km, or ₹1,875/month for 300 km.
- CNG: At 25 km/kg, it costs ₹3.00/km, or ₹900/month for 300 km, nearly half the cost of petrol.
Break-Even Analysis: The Punch CNG is ₹95,000–₹1.6 lakh more expensive than the petrol variant (ex-showroom). At a fuel cost savings of ~₹2.88/km (petrol manual vs CNG), you’d need to drive 33,000–55,600 km to recover the higher upfront cost of the CNG variant, making it economical for high-mileage users (e.g., 40,000–70,000 km over a few years).
Verdict: The Punch CNG is far more cost-effective for daily commuters driving over 1,000 km/month, while the petrol variant suits occasional drivers or those prioritizing performance.
