The petrol and diesel variants come with both manual and automatic transmission options. This combination of fuel types and transmission choices makes the Thar an appealing option for those seeking a balance of power, convenience, and efficiency. In this comparison, we will focus on a key factor for prospective owners: mileage.
We’ll share the official ARAI mileage figures for both petrol and diesel Thar variants, followed by real-world fuel efficiency insights. By the end, you’ll have a clear idea of which Thar variant offers the best combination of running costs and daily usability.
Mahindra Thar ARAI Mileage Figures
Official ARAI-certified mileage for the Mahindra Thar across all engine and transmission options is:
| Engine & Transmission | ARAI Mileage (km/l) |
| Petrol – Manual | 15.2 kmpl |
| Petrol – Automatic | 10.2 kmpl |
| Diesel – Manual | 15.2 kmpl |
| Diesel – Automatic | 13 kmpl |
Mahindra Thar Real-World Mileage vs ARAI Mileage
Although ARAI mileage figures are obtained under standardised test conditions, actual fuel efficiency in daily driving often differs. In city conditions, the Mahindra Thar petrol variant averages around 7-9.8 km/l, whereas the diesel model delivers approximately 10-12 km/l. On highways, the petrol variant achieves around 10-13 kmpl, while the diesel variant averages around 11.5-12.6 kmpl.
Several factors contribute to the difference between ARAI figures and real-world mileage:
- Driving Style: Aggressive acceleration and frequent braking can lower fuel efficiency.
- Traffic Conditions: Heavy city traffic with frequent stops reduces mileage compared to steady highway driving.
- Load & Air-Conditioner Use: Carrying extra passengers or using the AC extensively increases fuel consumption.
- Maintenance: Regular servicing, clean air filters, and correct tyre pressure help maintain optimal fuel efficiency.
For most buyers, the Mahindra Thar provides decent real-world fuel efficiency, with the diesel variant being a more economical choice for long-distance travel or frequent use.
Mahindra Thar Fuel Efficiency Comparison: Petrol vs Diesel
In terms of fuel efficiency, the Mahindra Thar’s petrol and diesel variants cater to different driving needs. The petrol version strikes a balance between power and mileage, offering an ARAI-claimed fuel economy that suits daily city commutes. On the other hand, the diesel variant, equipped with a more torque-focused engine, is designed for superior fuel efficiency on longer drives, making it ideal for enthusiasts who regularly cover high mileage.
In practical driving conditions, especially in urban traffic, the two variants demonstrate distinct characteristics. The petrol Thar provides steady performance, while the diesel model’s efficiency can fluctuate based on driving style and congestion levels. Therefore, understanding your regular driving habits is key when deciding between the petrol and diesel Mahindra Thar.
Mahindra Thar City Fuel Efficiency Comparison
City driving for the Mahindra Thar, whether petrol or diesel, generally offers decent fuel efficiency, though petrol models tend to use more fuel during frequent stops and starts. Diesel variants usually prove more economical in urban traffic due to stronger low-end torque. Automatic petrol versions deliver slightly lower mileage than their manual counterparts because of the torque converter, while diesel manual variants tend to perform better in slow-moving city traffic.
Key factors influencing this difference include:
- Fuel Characteristics: Diesel engines are more efficient at lower speeds, providing better mileage in stop-and-go conditions, making them suitable for city commutes. Petrol engines, on the other hand, consume more fuel in such driving conditions.
- Engine Tuning: Diesel variants are calibrated for optimal performance at low speeds, maintaining lower revs and enhancing mileage in congested traffic.
- Traffic Conditions: Petrol engines burn extra fuel for quick acceleration in heavy traffic, whereas diesel engines manage slow, steady traffic more efficiently thanks to superior torque.
- Idle Consumption: Diesel engines use less fuel while idling, contributing to better city mileage compared to petrol models.
- Temperature Management: Petrol engines tend to heat more in stop-and-go conditions, affecting fuel efficiency, whereas diesel engines maintain stable operating temperatures, helping achieve improved fuel economy.
Mahindra Thar Highway Fuel Efficiency Comparison
On highways, Mahindra Thar petrol variants generally offer smoother cruising and slightly better efficiency at moderate speeds, while diesel models provide higher torque, making them more capable for overtaking and tackling steep or uneven terrains. Manual petrol variants usually deliver better fuel economy than automatic versions due to more direct power transmission. Diesel Thar variants achieve remarkable mileage on long drives but may feel heavier during overtaking.
The factors affecting highway mileage differences include:
- Cruising Efficiency: Petrol engines tend to perform more efficiently at consistent speeds on open highways, whereas diesel engines excel in long-distance travel thanks to their superior torque and lower fuel consumption per kilometre.
- Load and Air-Conditioning Consumption: Fuel efficiency in both petrol and diesel Thar models decreases when the vehicle is fully loaded or the AC is used extensively. Diesel engines are slightly less affected due to their torque advantage.
- Driving Habits: Smooth acceleration and maintaining steady speeds are crucial for maximising mileage in both petrol and diesel Thar models. Frequent rapid acceleration or sudden braking can significantly lower fuel efficiency.
- Altitude and Terrain: Diesel Thar variants handle hilly or mountainous roads more effectively because of higher low-end torque, while petrol engines are more responsive on flat highways but may require more frequent gear shifts on inclines.
- Fuel Availability and Refuelling Stops: Planning long highway trips is important, especially for diesel Thar variants if fuel stations are limited in remote areas. Petrol variants are generally easier to refuel, which can indirectly affect overall travel efficiency and journey planning.
Mahindra Thar Fuel Cost Comparison: Petrol vs Diesel
Understanding fuel costs is essential when deciding between the Mahindra Thar petrol and diesel versions. Let’s break down the running expenses for an average monthly distance of 1,500 km, along with other factors, to see which option is more economical.
| Aspects | Petrol | Diesel |
| Monthly Running Distance | 1500 km | 1500 km |
| Monthly Fuel Use | Approx. 88 litres | Approx. 94 litres |
| Average Monthly Fuel Cost | ₹8,340* | ₹8,241* |
| Average Yearly Fuel Cost | ₹1,00,077* | ₹98,891* |
