The Tata Harrier, launched in India on 23 January 2019, is a mid-size SUV built on Tata’s OmegaArc platform derived from Land Rover’s D8 architecture. The Harrier shares its platform with luxury SUVs like the Range Rover Evoque and Discovery Sport, adding global pedigree to its Indian build. It received a major upgrade in October 2023, featuring a redesigned front profile, a 12.3-inch touchscreen infotainment system, ventilated seats, a panoramic sunroof, and advanced safety tech including ADAS. Known for its solid road presence and premium feel, the Harrier is powered by a 2.0-litre Kryotec diesel engine delivering 168 PS and 350 Nm of torque.

Checking your Tata Harrier's mileage is essential to understanding its fuel efficiency, planning long drives, and monitoring your SUV’s health over time. It also helps you identify driving patterns or mechanical issues that may be lowering mileage. With the Harrier’s diesel engine and varied terrain capabilities, tracking mileage ensures you get the best balance of performance and economy. You can check your Harrier’s mileage using the inbuilt MID (multi-info display) or by manually calculating it using fuel top-up methods.

Here’s a unique, step-by-step guide to check Tata Harrier mileage:

Method 1: Using the Built-In MID (Multi-Information Display)

This method is easy and is most used for checking the mileage of the Tata Harrier.

Step 1: Wait for the digital cluster to load as you ignite the engine of the Tata Harrier..

Step 2: Use the toggle button on the steering wheel to scroll to “Fuel Economy” or “Avg Fuel Cons.”

Step 3: The Harrier displays instantaneous mileage and average mileage post-reset.

Step 4: Reset it before a trip (long-press OK) to monitor accurate trip-based mileage.

Method 2: Through the Tata iRA Connected Car App (For iRA-enabled variants)

Works with variants compatible with the Tata IRA app, best for tracking mileage digitally.

Step 1: Open the Tata iRA app linked to your Harrier.

Step 2: Log in with your registered credentials, that is linked to Tata Harrier.

Step 3: Navigate to vehicle analytics or driving history.

Step 4: Check “Fuel Efficiency” reports over days/weeks.

Step 5: It calculates mileage using drive patterns, fuel level sensors, and route data.

Method 3: Full Tank to Full Tank (Manual Method – Most Accurate)

If you do not wish to use Tata’s features for calculating mileage, this is the most common method for most cars to calculate mileage.

Step 1: Fill your fuel tank to auto-cut-off at a trusted pump.

Step 2: Record the odometer or trip reading (e.g., Trip A = 0).

Step 3: Drive normally for 100–300 km.

Step 4: Refill at the same pump till auto-cut-off.

Step 5: Note the litres filled. Use the formula: Mileage = Kilometres Travelled ÷ Litres of Fuel Used

Mileage is calculated to understand the fuel cost of the vehicle. Understanding the mileage of a Harrier helps us determine the running cost of the Tata Harrier. To determine fuel costs, there is a formula. To understand how Harrier mileage helps with calculating fuel costs, let us see the example of Tauji.

Tauji drives his Tata Harrier every day from his village to the city for business. This journey is around 100 km to and fro. In a month, he has to go 22 days to the city and he uses his Tata Harrier for that purpose only. He calculated the total running costs of his Tata Harrier to determine his total profit for the business.

He used the following formula:

Fuel Cost = (Distance to be travelled ÷ Mileage) × Fuel Price per litre

Fuel Cost = (2200/16.8) * 90

• Total Distance Travelled = 22 days of travel × 100 km daily.
• Mileage = 16.75 km/l (User reported)
• Fuel price = 90, average diesel price

Fuel cost = ₹6,430 (approximately)

In this way, Tauji learnt that his monthly expenditure for diesel fuel would be ₹6,430 approximately. Through this, he can calculate his total profit by deducting the fuel price from his gross profit.

Here are a few tips for improving the mileage and fuel efficiency of the Tata Harrier:

1. Use Eco Mode for Daily Drives

The Tata Harrier offers Eco, City, and Sport driving modes. For maximum fuel efficiency, use Eco Mode during city commutes and moderate-speed cruising. It optimises throttle response and engine performance to conserve fuel.

2. Engage Cruise Control on Highways

Harrier variants equipped with cruise control benefit from stable speed management. Using cruise control at consistent speeds between 80 and 90 kilometres per hour helps reduce unnecessary acceleration and improves highway mileage.

3. Shift Gears at the Right RPM

In manual variants, shifting gears around 1500 to 2000 revolutions per minute ensures the Kryotec diesel engine operates efficiently. Avoid revving too high or letting the engine struggle at very low speeds.

4. Avoid Overuse of Terrain Modes

The Harrier offers terrain modes such as Rough, Wet, and Normal. Using terrain modes unnecessarily, especially on normal tarmac, can slightly reduce efficiency. Stick to Normal mode unless road conditions require otherwise.

5. Use AC Smartly

The Harrier’s dual-zone climate control system is powerful, but it can impact fuel economy. Set the temperature to moderate levels and use automatic climate control to maintain comfort without overworking the compressor.

6. Maintain Tyre Pressure and Alignment

Check tyre pressure weekly and keep it at the manufacturer-recommended level of around 33 PSI. Proper alignment every 5000 kilometres prevents drag and helps maintain optimal rolling resistance.

7. Reduce Unnecessary Load

The Harrier is already heavy due to its SUV build. Avoid storing extra luggage or accessories in the boot for long periods, as every 50 kilograms of extra weight can reduce fuel efficiency by one to two percent.

Mileage of Tata Harrier, or the number of kilometres the car runs, can affect insurance if you have pay-as-you-drive car insurance for Tata Harrier. In this type of car insurance, your premium is calculated by the distance you travel. This can be tracked using the odometer of the Tata Harrier. Here’s how car insurance is affected by the mileage of the Tata Harrier:

• Higher mileage may increase accident risk

The more you drive your Tata Harrier, the greater the chances of wear and tear, accidents, and costly repairs — all of which can contribute to a higher insurance premium.

• Low mileage can earn you savings.

If your car is driven less frequently, insurers may offer lower premiums as reduced usage typically translates to lower risk.

• Odometer checks matter

The odometer helps track the total distance covered by your Tata Harrier, offering an accurate measure of its real-time mileage and usage.

• Usage-based insurance through apps

Telematics-enabled or app-based policies monitor driving habits and distance, often rewarding low-mileage drivers with reduced insurance premiums.

Even if you don't opt for Pay-as-you-drive car insurance, do ensure that your Tata Harrier is paired up with the best possible car insurance – to be protected all the time and avoid legal hassles.

The Tata Harrier diesel mileage is 16.8 km/l (ARAI certified); however, considering driving conditions, modes, and terrain types, this mileage can be different for different users. Monitoring Harrier mileage will help you understand the running cost of your car,and also find any hindrances that are affecting the mileage of your vehicle. More importantly, do not forget to buy car insurance for Tata Harrier – it is legally mandatory, and financially crucial.
