•4wI am planning to buy the new Thar Roxx and really liked it after the test drive. My average monthly running is around 1000 km, and the car will mostly be used for weekend drives while remaining idle on weekdays. Should I choose the diesel or petrol variant?

In terms of fuel economy gains, there honestly isn't too much benefit in choosing the diesel version of the Mahindra Thar Roxx over the petrol.
Both engines are tuned for power and instantaneous responses, and suffer from terrible fuel economy. Perhaps if your driving is primarily on highways, you can extract a few extra kilometres out of the diesel version.
Both engines are about equal on refinement, too, so there are no gains made there either. As such, it might be worth going for the petrol version, if only to save some money on the cost price.
