I am planning to buy the Thar Roxx Star Edition. My monthly usage is around 1,000-1,200 km, with roughly 50% city and 50% highway driving. Should I choose the diesel or stick with the petrol?

Go for the diesel. At 1,000–1,200 km a month with a 50:50 city–highway split, the diesel makes sense. The Thar Roxx is a heavy, rugged SUV, and the diesel’s stronger low-end torque suits both city crawling and highway cruising. You will also see a meaningful difference in fuel efficiency over time, which matters at your running. Your highway running should also be enough to allow the DPF to regenerate properly.
The petrol is smoother and quieter in the city, but it will be thirstier. The diesel’s slightly higher upfront cost will take a while to recoup, but it is justified by your usage pattern and the Thar’s character. Overall, the diesel is the more sensible and satisfying choice for your driving mix.
