I am planning to buy a 7-seater, most probably the XUV 7XO AX7T petrol. My annual running will be around 7,000-8,000 km, with 80% on highways and the rest in the city. However, I am in a dilemma regarding the fuel efficiency of the petrol engine, as most reviews and discussions suggest going for the diesel engine. What should I choose: petrol automatic or diesel automatic?
Go for the XUV 7XO AX7T diesel automatic. With 7,000-8,000 km a year and 80 percent highway usage, the diesel makes more sense. The XUV 7XO diesel is a strong, refined engine with excellent highway performance and significantly better fuel efficiency than the petrol, especially at steady highway speeds. The petrol turbo is a good engine, but in a large 7-seater like the 7XO it will return noticeably lower fuel economy on long highway runs, and that difference adds up over time. The diesel automatic is smooth, has plenty of torque for effortless overtaking and cruising, and the ownership experience is strong. At your running, the diesel premium will take a few years to recover, but the fuel savings and the better highway driving experience make it worthwhile. The only reason to pick the petrol would be if your usage was predominantly city or you had a strong preference for petrol refinement. In your case, the diesel automatic is the clear recommendation.
