I currently own a Mahindra XUV 3XO TGDi (Revv variant) and have clocked 6,300km over the past eight months. However, I am averaging only 8–9kpl. Since around 80 percent of my driving is within the city and I prefer high-performance engines, should I consider switching to the Kia Seltos Diesel or the XUV 3XO Diesel?
At 80% city usage, switching to a diesel purely for better mileage doesn’t make much sense. Your 8–9kpl is on the lower side, but the T-GDi is the performance-oriented engine, and frequent stop-start traffic will naturally bring down its efficiency.
The Mahindra XUV 3XO diesel will deliver considerably better fuel economy and strong low-end torque, but it also brings the added complexity of a DPF. Since most of your driving is in the city, short and slow trips can make DPF regeneration more difficult. You would need to give the car occasional sustained runs to allow the system to regenerate properly.
The Kia Seltos diesel is the better of the two if you want to move to a larger and more premium SUV. It is refined, has strong torque, and the automatic is well suited to relaxed driving. However, you would still have the same DPF consideration, and neither diesel will give you the performance character of your T-GDi.
