Tata Punch CNG Engine Power in 2025 The Tata Punch CNG, a popular compact SUV in India, has gained attention for its fuel efficiency, safety, and affordability in 2025. Powered by Tata Motors’ innovative iCNG twin-cylinder technology, it offers a balance of eco-friendly performance and practical city driving. However, its engine power is a key consideration for buyers comparing it to petrol variants or rival CNG models. This SEO-friendly article dives into the Tata Punch CNG engine power, specifications, real-world performance, and a comparison with its petrol counterpart to help you decide if it meets your driving needs.

Tata Punch CNG Engine Overview

The Tata Punch CNG is equipped with a 1.2L Revotron 3-cylinder engine optimized for CNG operation. It uses Tata’s iCNG technology, featuring two 30-litre (water equivalent) CNG tanks (total 60 litres) and a single ECU for seamless switching between CNG and petrol modes. The engine is paired with a 5-speed manual or 5-speed AMT transmission, making it versatile for city and highway driving. Its standout feature is the direct CNG start, eliminating the need to start in petrol mode, which enhances efficiency and convenience.

Key Engine Specifications

Specification Tata Punch CNG
Engine 1.2L Revotron, 3-cylinder
Power 72.41 bhp @ 6000 rpm
Torque 103 Nm @ 3250 rpm
Fuel Type CNG (primary), Petrol (backup)
Transmission 5-speed Manual, 5-speed AMT
Fuel Tank Capacity 60L (CNG), 37L (Petrol)
Mileage (ARAI) 26.99 km/kg (CNG)
  • Power Output: The CNG variant produces 72.41 bhp at 6000 rpm, which is lower than the petrol variant’s 84.82 bhp due to CNG’s lower energy density.
  • Torque: It delivers 103 Nm at 3250 rpm, sufficient for city driving but slightly less responsive than petrol for high-speed overtaking.
  • iCNG Technology: The twin-cylinder setup optimizes boot space (210 litres) while maintaining performance, with advanced safety features like leak detection and thermal protection.

Real-World Performance of Tata Punch CNG Engine

The Tata Punch CNG’s 72.41 bhp and 103 Nm provide adequate power for urban commuting and occasional highway trips. Here’s how the engine performs in real-world scenarios:

  • City Driving: In congested city conditions (e.g., Delhi, Mumbai), the engine offers smooth performance at low to mid-range speeds (20–60 kmph). The torque delivery at 3250 rpm ensures easy navigation through traffic, with minimal lag during gear shifts. Users report the AMT variant is particularly convenient for stop-go traffic, though manual variants offer better control.
  • Highway Performance: On highways, the Punch CNG is capable of cruising at 80–100 kmph, but the lower power output (compared to petrol) is noticeable during quick overtaking or climbing steep inclines, especially with a full load (4–5 passengers). The engine feels adequate for steady cruising but may require downshifting for rapid acceleration.
  • Acceleration: The 0–100 kmph sprint takes around 14–15 seconds (based on Autocar India tests), slower than the petrol variant’s ~12–13 seconds, reflecting the CNG’s reduced power.
  • Refinement: The 3-cylinder engine is smooth in CNG mode, with minimal vibrations compared to older CNG vehicles. The single ECU ensures seamless CNG-petrol switching without performance hiccups.

User Feedback: Owners on platforms like Team-BHP and 91wheels.com praise the engine’s reliability for daily commutes, reporting no major issues in city conditions. However, some note a slight power lag on highways when fully loaded or during aggressive overtaking.

Tata Punch CNG vs Petrol: Engine Power Comparison

To understand the Tata Punch CNG engine power, it’s helpful to compare it with the Tata Punch Petrol variant, which uses the same 1.2L Revotron engine but is tuned for higher output.

Specification Tata Punch CNG Tata Punch Petrol
Power 72.41 bhp @ 6000 rpm 84.82 bhp @ 6000 rpm
Torque 103 Nm @ 3250 rpm 113 Nm @ 3300 rpm
Transmission 5-speed Manual, 5-speed AMT 5-speed Manual, 5-speed AMT
Mileage (ARAI) 26.99 km/kg 20.09 kmpl (Manual), 18.8 kmpl (AMT)
0–100 kmph ~14–15 seconds ~12–13 seconds
  • Power Difference: The petrol variant’s 84.82 bhp (12.41 bhp more) and 113 Nm (10 Nm more) make it more responsive, especially for highway driving or quick acceleration. The CNG variant sacrifices some power for better fuel efficiency.
  • Performance Impact: In city conditions, the power difference is less noticeable, as the CNG’s torque is sufficient for low-speed driving. On highways, the petrol variant feels peppier, especially when overtaking or climbing gradients.
  • Fuel Efficiency Trade-Off: The CNG’s 26.99 km/kg (real-world 20–22 km/kg in city) far surpasses the petrol’s 15–17 kmpl in city conditions, making it more cost-effective for high-mileage drivers.

Running Cost Example (Delhi, 2025):

  • CNG: ₹75/kg, 21 km/kg (city) = ₹3.57/km
  • Petrol: ₹100/litre, 16 kmpl (city) = ₹6.25/km
  • Savings: The CNG saves ~₹2.68/km, or ₹1,340/month for 500 km, offsetting its lower power with significant cost benefits.

Verdict: The Punch CNG is ideal for city commuters prioritizing fuel savings, while the petrol variant suits those needing better performance for mixed city-highway use.

Strengths of Tata Punch CNG Engine Power

  • Adequate for City Use: The 72.41 bhp and 103 Nm are well-suited for urban speeds (20–60 kmph), offering smooth performance in traffic.
  • Eco-Friendly: Lower emissions compared to petrol, aligning with India’s push for greener fuels in 2025.
  • Seamless CNG Operation: Direct CNG start and single ECU ensure smooth transitions between CNG and petrol modes without power loss.
  • Reliability: The 1.2L Revotron engine is proven for durability, with minimal maintenance issues reported by owners.
  • AMT Option: The 5-speed AMT enhances ease of use in city traffic, compensating for the slightly lower power output.

Limitations of Tata Punch CNG Engine Power

  • Reduced Power vs Petrol: The 72.41 bhp is noticeably less responsive than the petrol’s 84.82 bhp, especially on highways or with a full load.
  • Highway Overtaking: Quick acceleration requires planning and downshifting, as the 103 Nm torque peaks at 3250 rpm.
  • Load Sensitivity: Performance drops slightly with 4–5 passengers or heavy luggage, particularly on inclines.
  • CNG Availability: Dependence on CNG stations can be a hassle in areas with limited infrastructure, though the 37L petrol tank serves as a backup.

Tips to Optimize Tata Punch CNG Engine Performance

  1. Drive in Optimal RPM Range: Keep the engine between 2000–3500 rpm for the best balance of power and efficiency in city traffic.
  2. Use CNG Mode: Operate in CNG mode for city driving to maximize mileage (20–22 km/kg) and minimize costs.
  3. Avoid Overloading: Limit passengers to 2–3 and avoid heavy cargo to maintain responsive performance.
  4. Plan Highway Drives: For long trips, anticipate overtaking needs and use lower gears to access peak torque.
  5. Regular Maintenance: Service the CNG system every 10,000 km to ensure optimal fuel delivery and power output.
  6. Refuel at Trusted Stations: Use reputable CNG stations (e.g., Indraprastha Gas) to avoid impure fuel that can reduce power and efficiency.
