Tata Nexon Mileage Comparison: Petrol vs CNG vs Diesel vs Electric (2026)

The Tata Nexon is a robust compact SUV for modern families. It delivers practicality, comfort and even a striking road presence in the segment. You get an unmatched choice of four distinct powertrains today. You can pick petrol, diesel, factory-fitted CNG, or pure electric. The petrol engine gets manual, AMT, or automatic transmissions. The diesel version comes with a manual or AMT gearbox. The CNG variant currently uses a manual transmission. The electric version offers clutchless, silent automatic driving. 

This Tata Nexon mileage comparison is vital for your budget. Buyers wanting smooth city commutes often pick the standard petrol. Driving enthusiasts prefer the punchy electric vehicle performance. Budget-conscious drivers love the excellent fuel efficiency of diesel. People often ask, does Tata Nexon have cng? Yes, Tata introduced a highly advanced twin-cylinder CNG model recently.

Variant-Wise Price Difference

We must evaluate prices before detailing the Tata Nexon mileage. It is crucial to see the premium for different powertrains. Let us examine the starting ex-showroom prices for each type.

There is a noticeable price premium for different propulsion systems. You pay an extra ₹91,000 for the CNG over petrol. The base Tata Nexon CNG price is highly competitive. The diesel demands a larger premium over the standard petrol. The electric version requires the highest initial investment. This upfront price drastically impacts your overall ownership budget.

Tata Nexon ARAI Mileage Figures

Here are the official lab-tested figures for the Nexon range.

Disclaimer: Official Tata Nexon mileage does not equal real-world figures. ARAI tests occur under highly controlled laboratory environments. Real-world traffic and driving styles yield slightly different average numbers.

Tata Nexon Mileage vs Competitors

The Maruti Brezza delivers a higher official petrol average. The Nexon remains unique by offering all four fuel types. The Nexon diesel remains highly popular for long-distance cruising. Interestingly, its fiercest domestic rival also offers potent powertrains; the Mahindra XUV 3XO mileage comparison reveals a refined 20.60 km/l on diesel. However, the Nexon goes one up with its innovative twin-cylinder CNG that provides incredible practicality over rivals.

Tata Nexon Real-World Fuel-Efficiency (City vs Highway)

Below is the real-world average of the Nexon engines. These figures represent typical Indian city and highway driving conditions. Reputable automotive forums confirm these realistic owner figures.

In city traffic, the standard petrol delivers 10-12 km/l. The diesel automatic returns a much higher 14-16 km/l. The CNG manages roughly 14-16 km/kg in dense traffic. The Long Range EV comfortably delivers 300 kilometres per charge. On the highway, the diesel easily achieves 18-20 km/l. The petrol manages 15-17 km/l under relaxed cruising conditions. The CNG can stretch to 18 km/kg on highways. 

Real-world numbers differ from ARAI because tests exclude AC. Heavy city traffic impacts fuel efficiency due to constant idling. Smooth throttle inputs significantly improve your highway fuel efficiency.

Do note that maintaining the right Tata Nexon tyre pressure is important to obtain the right mileage.

Nexon Petrol vs Diesel vs CNG vs EV: Performance Comparison

Beyond fuel efficiency, engine performance varies drastically across the range.

The electric vehicle is the clear performance winner here. It offers thrilling, instant acceleration and effortless high-speed overtakes. The diesel engine provides excellent low-end torque for city driving. The standard petrol is very responsive but slightly vocal. The CNG version feels slightly slower on steep hill climbs.

Petrol vs Diesel vs CNG vs EV: Cost Comparison

Nexon running cost

We must use real-world numbers to understand actual running costs. We will use the Tata Nexon average for accurate calculations.

• Assume petrol costs ₹100 per litre for this calculation.
• Assume diesel costs ₹90 per litre for this calculation.

• Assume CNG costs ₹80 per kg for this calculation.

   

Assume home charging costs ₹800 per full EV charge.

The difference becomes quite clear in realistic driving conditions. The electric variant is by far the cheapest to run. Your running cost with the standard petrol is ₹7.69. The diesel and CNG running costs drop to roughly ₹5.30. Electric vehicle maintenance is also lower over the long term. EV and CNG models remain economical for heavy daily usage.

Monthly & 5-Year Fuel Cost Projection

Let us assume a realistic scenario of driving 1500 km monthly. This reveals your total fuel expenses over a long period.

The savings with the EV and diesel are truly massive. You save roughly ₹7,785 every single month with the EV. You will recover the upfront EV premium over several years. After that period, you enjoy pure savings on every commute. The CNG and diesel remain neck-and-neck for lifetime fuel costs.

Practical Ownership Tradeoffs

Whether you are buying a new or a used Tata Nexon, here are the things you need to consider before deciding between the powertrain options:

• Refinement and Noise

   

The electric vehicle is completely silent and incredibly refined. The diesel engine has a noticeable clatter during morning starts.

• Boot Space Impact

   

The Nexon uses smart twin-cylinder technology for its CNG models. This preserves a highly usable boot space, unlike traditional kits.

• Charging and Refuelling

   

CNG infrastructure in India is expanding but faces long queues. EVs require home charging access or reliable public fast chargers.

• DPF Issues

   

Modern diesel cars have a Diesel Particulate Filter. Driving solely in slow traffic can cause DPF clogging issues. Highway runs are necessary to keep the diesel engine healthy.
