I am confused between the XUV 7XO petrol and diesel, both with automatic gearboxes. My monthly running is 600-800 km, with frequent highway trips. I really like diesel cars but am worried about DPF issues. Which one should I choose?

Go for the Mahindra XUV 7XO diesel automatic. With your monthly running of 600-800 km and frequent highway trips, you are exactly the kind of user for whom a modern diesel makes sense. The XUV 7XO diesel has a strong, refined engine that offers excellent highway performance and efficiency, and the automatic gearbox is well matched to it. Your usage pattern is also ideal for DPF health: frequent highway runs allow the system to regenerate properly, so DPF issues are extremely unlikely. The petrol is a good engine too, but it will not deliver the same torque-rich, effortless highway performance or the same fuel economy on long runs. If you love diesel, this is the right car for you. Just make sure you are doing at least one decent highway run every couple of weeks, and you will not have any DPF concerns.

Go for the XUV 7XO AX petrol. It is the better fit for your priorities. The 2.0-litre turbo-petrol is a proven engine with a strong ownership track record, and delivers significantly better performance than the Safari’s 1.5-litre turbo-petrol. The Mahindra XUV 7XO feels more effortless on the highway, especially with a full load, and overtaking is easier thanks to its stronger mid-range.It is also the more mechanically sorted package overall, with a better-calibrated gearbox and a more mature ownership experience.The Tata Safari’s 1.5-litre turbo-petrol is adequate for city driving, but it can feel strained on the highway with a full load and does not offer the same level of performance, refinement, or long-distance ease as the engine in the Mahindra car.For your usage pattern, low running with occasional long highway trips, petrol is the right choice, and the XUV 7XO’s engine is better suited to this kind of usage. It is a robust, reliable powertrain that can handle high mileage over the long term, and it does not suffer from the same concerns around DPF or diesel-related issues that can arise with low usage.If you are open to alternatives, the Toyota Innova HyCross is worth considering. It is not an SUV, but it is the benchmark for long-term reliability and ownership experience. The hybrid powertrain is extremely well suited to your usage pattern. It is also a genuinely comfortable long-distance car with a proven track record.
