Tata Harrier vs Mahindra Scorpio N Specs
Before comparing Tata Harrier vs Mahindra Scorpio N on the basis of their fuel-efficiency, let’s compare them on the basis of their key specifications:

| Transmission | 6-speed manual transmission (MT)6-speed automatic transmission (AT) | 6-speed MT 6-speed AT |
| Drive layout | Front Wheel Drive (FWD) | Rear Wheel Drive (RWD) 4×4 (4WD) |
| Kerb weight | 1650 kg to 1825 kg (depending upon the variant) | 1770 kg to 2070 kg (depending upon the variant) |
| Fuel tank capacity | 50 litres | 57 litres |
Mahindra Scorpio N is not only heavier than Tata Harrier but it also comes with a bigger petrol and diesel engine that generate more power and torque. Also, Scorpio N cars are equipped with either RWD or 4WD drivetrain which add additional weight and friction to their driving dynamics. These things force the engine to work more to keep the car moving. All these factors reduce the mileage of Scorpio N, especially if we compare it to the Tata Harrier models that appear similar in size. Harrier has a more aerodynamic design and its lesser kerb weight along with smaller engine size leads to a better fuel-economy irrespective of the road conditions.
Tata Harrier vs Mahindra Scorpio N: ARAI Mileage Figures
ARAI mileage tests are done in a lab-controlled manner in ideal driving conditions and with a minimum load in the car. These factors enable the vehicles to achieve a higher score during the ARAI tests whereas the real-world mileage depends on the road conditions, driving style, and other factors. As a result, ARAI mileage figures tend to exceed the real-world fuel-economy of cars. The below table gives the comparison of ARAI mileage figures of Tata Harrier vs Mahindra Scorpio N for each powertrain:
| Engine & Transmission | Fuel Type | Tata Harrier – ARAI Mileage (km/l) | Mahindra Scorpio N – ARAI Mileage (km/l) |
| 1.5-litre Turbo-GDI with 6-speed MT | Petrol | Up to 17 km/l | – |
| 1.5-litre Turbo-GDI with 6-speed AT | Petrol | Up to 17 km/l | – |
| 2.0L Turbo-Petrol with 6-Speed Manual (MT) | Petrol | – | 12.17 km/l |
| 2.0L Turbo-Petrol with 6-Speed Automatic (AT) | Petrol | – | 12.12 km/l |
| 2.2L Diesel – 6-Speed Manual (MT) | Diesel | – | 15.94 km/l |
| 2.2L Diesel – 6-Speed Manual (MT) | Diesel | – | 15.42 km/l |
| 2.0L Kryotec Turbocharged Diesel with 6-speed MT | Diesel | 16.8 km/l | – |
| 2.0L Kryotec Turbocharged Diesel with 6-Speed AT | Diesel | 16.8 km/l | – |
The above table suggests that the petrol engine of Tata Harrier delivers more mileage than its diesel engine. However, in the real-world conditions, the diesel engine proves to be more fuel-efficient. The ARAI claimed mileage of Mahindra Scorpio N variants are also less than Tata Harrier cars irrespective of the fuel-type.

Tata Harrier diesel variants offer a slightly better mileage than the diesel variants of Mahindra Scorpio N. Despite this, the larger fuel-tank capacity of Scorpio N enables it to offer a slightly better full-tank range in real-world conditions. However, that doesn’t mean it is more fuel-efficient than the Tata Harrier.
Scorpio N has been engineered to deliver a rugged off-roading performance while maintaining steadfast acceleration on the roads and highways. On the other hand, the petrol and diesel engines of Tata Harrier models are refined to offer a balance of power, smooth-ride-quality, and performance. So, they end-up delivering slightly better mileage than Scorpio N variants in both the petrol and diesel engine options. However, the difference in their city and highway fuel-economy isn’t huge enough to affect a buyer’s decision.

Tata Harrier vs Mahindra Scorpio N: Fuel Cost Comparison
After evaluating their real-world mileage figures, let’s see how they translate to periodic fuel costs. For that, we have considered a standard running of 1500 km per month for both the cars. The current price of petrol (Rs. 111.52) and diesel (Rs. 98.15) as per August 2026 are used for calculating the monthly, yearly, and 5-yearly fuel costs of these cars:
| Harrier Petrol | Scorpio N Petrol | Harrier Diesel | Scorpio N Diesel | |
|---|---|---|---|---|
| Monthly Running | 1500 km | 1500 km | 1500 km | 1500 km |
| Monthly Fuel Use | 128 L | 136 L | 103 L | 108 L |
| Average Monthly Fuel Cost | ₹ 14,274 | ₹15,166 | ₹ 10,109 | ₹ 10,600 |
| Average Yearly Fuel Cost | ₹ 1.71 lakh | ₹ 1.81 lakh | ₹ 1.21 lakh | ₹ 1.27 lakh |
| 5-Year Fuel Cost | ₹ 8.55 lakh | ₹ 9.05 lakh | ₹ 6.05 lakh | ₹ 6.35 lakh |
If we look at this comparison table, it is clear that the monthly, yearly, and 5-yearly fuel costs of Tata Harrier is much lesser than the Mahindra Scorpio N, irrespective of the fuel-type. However, this difference is more significant with the petrol variants as compared to the diesel variants.

Tata Harrier vs Mahindra Scorpio N Price
The prices of Tata Harrier models and Mahindra Scorpio N models are compared in the below table:
| Model | Variant (Base to Top) | Price (Ex-Showroom) |
| Tata Harrier | Smart to Fearless X Plus/Dark Edition | ₹ 12.89 to ₹ 25.25 lakh |
| Mahindra Scorpio N | Z2 to Z8L | ₹ 13.69 to ₹ 25.49 lakh |
The Mahindra Scorpio N is slightly more expensive than Tata Harrier if we compare their base and top models. However, this difference is negligible and may hardly affect a buyer’s decision.
Summary
Both Tata Harrier and Mahindra Scorpio N are huge and bulky vehicles that also generate a fair amount of power and torque. However, Scorpio N is designed for a more aggressive performance and its RWD and 4WD drivetrain options along with a heavier kerb weight lead to an overall higher fuel consumption than Tata Harrier cars. You can pick any of the petrol variants if you want to drive in the city as the difference is hardly noticeable. However, if your running is higher and mostly comprises long trips and highway routes, buying the diesel variants of Tata Harrier makes more sense.
