Tata Altroz: An overview

The Tata Altroz is a premium hatchback with 5-passenger seating. The Tata Altroz has become one of the most popular hatchbacks in India. This is because:

  • Five-star Global NCAP rating
  • Six airbags are standard across variants
  • 10.25-inch digital instrument cluster
  • 9-inch touchscreen infotainment
  • Wireless Android Auto and Apple CarPlay
  • 360-degree camera system
  • Sunroof availability
  • iRA connected car technology

The Tata Altroz can be equipped with either a Revotron 1.2 petrol engine, a Revotorq 1.5 diesel engine, or an iCNG powertrain. All variants of the Altroz are available with either a manual or a DCA (petrol) automatic transmission.

However, despite having many premium features, it is highly likely that the Tata Altroz’s mileage is a major consideration in one’s decision to purchase the vehicle.

Tata Altroz Real-world vs ARAI mileage

ARAI mileage is the estimated fuel economy of a vehicle under testing conditions. However, it does not accurately reflect the Tata Altroz's daily fuel economy due to the high variability of factors affecting fuel consumption.

Tata Altroz Real-world mileage

Here is the Tata Altroz's real-world mileage data for your understanding:

Fuel type

City mileage

Highway mileage

Petrol MT/DCA

10.5-14 kmpl

15-18 kmpl

Diesel MT

17-19 kmpl

21-23 kmpl

Note: The above-stated Tata Altroz mileage is an estimate and may vary depending on driving and road conditions.

Tata Altroz: City vs highway mileage

The Tata Altroz's real-world mileage differs between city roads and highways. Here is a quick overview of the same:

Fuel type

City mileage

Highway mileage

Petrol MT/DCA

11-14 kmpl

16-18 kmpl

Diesel MT

17-19 kmpl

30-34 km/kg

The actual Tata Altroz mileage can still differ, depending on your driving habits and car condition.
 

Factors affecting the Tata Altroz Mileage

Driving style, road environment, and maintenance are the keys to maximising the Tata Altroz's mileage. Little changes in your daily driving behaviour will help you achieve good fuel savings in the long term. The following factors all have an impact on the Tata Altroz Mileage:
 

Traffic and road conditions

Experiencing traffic on a daily basis leads to frequent acceleration and deceleration. This driving style significantly reduces your Tata Altroz's mileage, as the engine has to work much harder. 


Selecting fuel-efficient routes with the least traffic and the smoothest surface will help reduce overall fuel consumption. If you can maintain a steady speed between 40km/h and 60km/h, then this will also help reduce jolts and improve the overall Tata Altroz mileage.
 

Driving habits

The mileage that you get from your Tata Altroz can be significantly impacted by sudden accelerations, constant braking, or aggressive overtake manoeuvres. Another aspect of driver error is excessive engine revving, which is hard on the engine and increases fuel consumption. Speeding increases wind resistance, which reduces your Tata Altroz's mileage.


If you want to maximise your vehicle's fuel efficiency, you can do so by driving smoothly and gradually increasing/decreasing your speed by avoiding sudden acceleration, and by keeping your engine in the middle RPM range. 
 

AC usage

Running your car’s air conditioning (AC) unit is common for anyone who drives in hot weather; however, running it at full blast negatively affects your Tata Altroz's mileage. The constant operation of the air conditioning system places excessive strain on the engine, reducing efficiency.


When driving at highway speeds, opening the windows is also counterproductive to improving your Tata Altroz's mileage, as it increases wind resistance. If you maintain your comfort level with moderate AC settings or recirculating mode, you will place less load on your engine, which will positively impact the fuel consumption of your Tata Altroz. 
 

Vehicle load

The load a vehicle carries directly impacts its fuel consumption. For example, more load means an increased strain on your engine, thus reducing the overall fuel economy of a Tata Altroz, etc. More specifically, if you're driving on an incline, you'll put more strain on the engine because it has to work harder than when you're going uphill with no load.
 

If you eliminate unnecessary weight from your car before departing your point of origin. You could greatly improve your Tata Altroz's fuel economy by keeping the car "light," thereby reducing fuel consumption during acceleration.
 

Tyre pressure

Tyres need constant monitoring because if tyre pressure is lower than recommended or incorrect, you will encounter much more rolling resistance. This dramatically reduces your Tata Altroz's fuel economy. Using non-recommended tyres will also lead to higher rolling resistance than original manufacturer-approved tyres.
 

Make it a habit to check the tyre pressure every time you go to the fuel station. Low tyre pressure contributes to poor vehicle handling and the potential for long-term negative impact on the fuel economy of your Tata Altroz.
 

Maintenance routine

Many people do not consider service intervals important; however, failing to follow the service interval schedule can lead to significant issues with your car. The engine will eventually become inefficient due to clogged fuel/air filters, overly worn components, and/or overly aged engine oil, all of which will reduce your Tata Altroz's mileage. 
 

Following the service schedule specified in your Tata Altroz owner's manual on time will also help ensure that all of the engine's internal components operate efficiently and do not negatively affect your Tata Altroz's fuel economy.

Conclusion

The Tata Altroz is a value-rich premium hatchback. It is essential to evaluate all aspects prior to making an informed decision. Arguably, the main consideration when purchasing a vehicle is the expected mileage. The expected Tata Altroz mileage may vary depending on real-world conditions, but the ARAI-certified mileage figure is a good indicator.
 

Using preventive maintenance and practising good driving habits can produce satisfactory Tata Altroz mileage for many years to come.

Frequently Asked Questions 

Here are a few common questions and their answers about the Tata Altroz Mileage: Real World vs ARAI Mileage:.

Icon
Is the Tata Altroz mileage different in the city than on the highway?

Yes, there are mileage differences in the Tata Altroz depending on driving location, due to different driving surfaces or speed limits.

How can I improve the Tata Altroz mileage?

You can increase your Tata Altroz mileage by accelerating smoothly, reducing idle time, and maintaining a consistent speed.

Does the AC usage impact the car's mileage?

Yes, the higher the AC output, the greater the impact on the engine, and, subsequently, the lower the fuel economy over time.

Which Tata Altroz variant has the best city fuel economy? 

The best city fuel economy with the Tata Altroz is offered by the diesel manual variant.

Does the iCNG Tata Altroz provide better mileage than a petrol-powered Tata Altroz? 

Yes, the iCNG Tata Altroz mileage is reported to be between 19.8 km/Kg and 34 km/Kg, while the petrol engine has recorded fuel consumption between 10 km/l and 18 km/l.

Which transmission option provides the best Tata Altroz mileage while in stop-and-go traffic? 

The DCA automatic transmission can optimise gear shifts, providing optimal Tata Altroz mileage in stop-and-go traffic compared to a manual transmission.

Does the diesel Tata Altroz generally offer the best fuel economy? 

The diesel Tata Altroz has been reported to achieve a mixed fuel economy of 18-20 km/l, while the petrol Tata Altroz provides a mileage of 14-15 km/l.

What is the driving range on a full tank of petrol for the Tata Altroz? 

The petrol Tata Altroz has a usable driving range of approximately 600-660 km, based on average fuel economy.

Will maintaining proper tyre pressure improve my Tata Altroz mileage? 

Yes, if you maintain proper tyre pressure, you can prevent a loss of 1 km/l to 2 km/l in fuel economy and improve the Tata Altroz fuel economy by reducing rolling resistance.

Will I see an improvement in mileage if I service my Tata Altroz regularly? 

Yes, if you regularly change the fuel and air filters on your Tata Altroz, you will improve fuel economy by maintaining proper fuel delivery and increasing airflow. This can provide an average 1-to-2 km/l improvement in Tata Altroz mileage.
