•15hI am planning to buy the Mahindra XUV 7XO but am confused about whether to choose the petrol or diesel variant. My annual running is approximately 12,000 km, with around 7,000 km in city driving (Gurgaon) and 5,000 km on highways. While the petrol variant offers lower mileage, I am concerned about potential restrictions on diesel vehicles during the winter season in the Delhi-NCR region. Could you please guide me on which option would be more suitable, considering I reside in Delhi-NCR?

As per your location and usage, we would suggest you go for the petrol-automatic Mahindra XUV 7XO. Yes, its fuel efficiency is on the lower side, especially in crawling bumper-to-bumper traffic. On the open road, though, with steady acceleration and maintaining speeds below 100kph, you could maximise fuel efficiency.
Also, besides having a longer registration life of 15 years (vs diesel's 10 years), the petrol is also not prone to DPF-related issues. It could crop up in the diesel version if you don't drive adequately on the highway.
Go for the diesel-automatic only if you will certainly drive adequately on the open road every fortnight or month to burn off the soot collected in the filters. If you plan on keeping this vehicle for 3-5 years at the max, in which case, its shorter registration life won't matter much.
Lastly, if you opt for the diesel-automatic, rest assured, new-age diesel vehicles aren't likely to face temporary bans and limitations to ply on the road when pollution increases.
