Budget-conscious drivers focus entirely on the excellent diesel fuel efficiency.

Variant-Wise Price Difference

Before we proceed with the comparison, we must check prices. It is very important to understand the engine powertrain premium. Let us look at the ex-showroom price differences today.

There is a substantial premium for the CNG fitment. You also pay a significant extra amount for the diesel. Standard petrol variants are the most affordable upfront choice.

Official ARAI Testing Figures

Here are the official lab-tested figures for the vehicle. These numbers showcase the claimed Tata Altroz mileage.

Disclaimer: ARAI testing mileage is not the real-world average. ARAI figures are tested under strictly controlled laboratory conditions. Real-road driving provides slightly varying fuel efficiency statistics.

Mileage vs Competitors

Let us see how it fares against market rivals.

The Hyundai i20 does not offer a diesel or CNG. The Tata Altroz provides a highly balanced overall performance. It offers the greatest mix of diverse powertrain options.

The Tata Altroz diesel delivers a superb highway average compared to its petrol counterpart. However, if maximum petrol efficiency is your ultimate priority, the Maruti Baleno mileage comparison showcases a class-leading 22.35 km/l and a highly economical 30.61 km/kg on CNG.

Real-World Average (City vs Highway)

Below is the real-world average of the Tata Altroz. This covers both city and open highway driving conditions.

In city driving conditions, the standard petrol delivers around 13 km/l. The diesel returns a significantly higher 17 km/l. On the highway, the fuel efficiency gap becomes much wider. The diesel stretches further with an impressive 21 km/l. The CNG variant provides incredible economy in city traffic. 

Real-world numbers differ from official ARAI testing figures. Lab tests completely exclude heavy traffic and air conditioning. Smooth driving styles will significantly improve your highway average.

Since heavier cars require more energy to roll, maintaining the right Tata Motors Altroz tyre pressure is important to obtain the right mileage.

Engine Specifications and Performance

Beyond fuel efficiency, let us compare the performance specifications.

The drivability difference is very noticeable during highway overtakes. The diesel offers immense torque for pulling heavy loads. You will feel a slight power drop in CNG mode. Standard petrol engines are incredibly smooth and very silent.

Running Cost Analysis

Daily Cost Per Kilometre

To understand the true running cost difference, we need data. We must use the real-world average, not just ARAI figures. We assume petrol costs roughly ₹100 per litre. We assume diesel costs roughly ₹90 per litre. We assume CNG costs roughly ₹80 per kg.

When you factor in realistic conditions, the difference is massive. The CNG variant costs the absolute least per kilometre. Your running cost with standard petrol is roughly ₹6.66. The CNG running cost drops to just ₹3.63 per kilometre. The diesel variant remains highly economical for highway users. The CNG option is significantly cheaper for high-mileage users.

Long-Term Ownership Projections

Let us assume you drive 1,500 kilometres every single month. This reveals your total fuel expenses over a specific timeframe.

The fuel savings with the CNG version are quite phenomenal. You save roughly ₹4,500 every single month over petrol. The diesel and CNG variants require a higher purchase price. However, daily commuters easily recover this initial cost quickly.

Practical Ownership Tradeoffs

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

• Initial Purchase Cost

  
  The diesel variant demands a significantly higher upfront premium. You must pay extra for the complex diesel engineering. Standard petrol cars are cheaper to buy right now.

   

• Refuelling Convenience

  
  CNG cars require dedicated infrastructure and slightly longer waiting times. You might face queues at city CNG stations. Diesel and petrol fuel stations are available absolutely everywhere instantly.

   

• Boot Space Impact

  
  Tata uses clever dual-cylinder technology for the CNG model. This ensures you still get highly usable boot space. Standard petrol and diesel models offer full luggage capacity.

   

• Maintenance and Care

  
  Diesel engines require timely and strict engine oil changes. CNG vehicles might need more frequent spark plug replacements. Petrol engines are generally the easiest to maintain long-term.

   

Buying Verdict: Which Should You Choose?

Choose Petrol if:

1. You primarily drive in heavy stop-and-go city traffic.
2. Your daily running distance is relatively very low.

3. You prefer lower upfront vehicle purchasing and loan costs.

    

Choose CNG if:

1. You want the absolute lowest daily running costs possible.
2. Your daily commute exceeds fifty kilometres in heavy traffic.

3. You have easy access to local CNG refuelling stations.

    

Choose Diesel if:

1. You frequently drive on open highways for long trips.
2. You travel with heavy luggage and full passenger capacity.
3. You want excellent torque and highly punchy overtaking performance.
