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.

@texaslion, if you are considering to buy a diesel car by selling of the current car, it wont benefit you financially by switching to diesel for better fuel efficiency, you would have lost atleast 20% of the value of your car, which exceeds the financial benefit which you could reep from buying an efficent diesel engine.My suggestion is that if you are not genuinely happy with the products reliability and if its giving some unresolved issues, only then considering switching to a newer car.
When will Mahindra vision x release in India and what would be estimated on road price for automatic?
@texaslion Go with Mahindra XUV 3XO 👍with the current.. Diesel won't fetch you much mileage and stick to whatever 3xo is with you unless you are looking for big Suv.
