Mahindra Thar Roxx petrol or diesel buying advice

I am interested in the Mahindra Thar Roxx. My monthly running is between 1,500km and 2,000km. Should I go for a diesel or petrol powertrain?

Autocar India says: Given your monthly running of 1,500-2,000km (or roughly 50-60km a day), the diesel version of the Thar Roxx makes more financial sense. The petrol variant, while smoother in certain conditions, will prove significantly more expensive to run over time.

The 2.2-litre mHawk diesel is also one of the best in its class – refined, torquey and strong on performance – so you’re unlikely to feel short-changed or left wishing for a petrol instead.

The only thing to keep in mind with the BS6 diesel is the DPF (Diesel Particulate Filter) system. To keep it working efficiently, it’s advisable to take the car out on longer highway drives every now and then so the system can regenerate properly.

All things considered, the diesel Roxx is the more practical and rewarding choice for your usage.
