My budget is around ₹20 lakh on-road, and I am specifically looking for a diesel SUV. My usage pattern would be roughly 80% highway driving, 15% city driving, and 5% mild off-road usage. My priorities are: Spacious cabin Good fuel efficiency Comfortable ride quality I can compromise slightly on outright performance if the car excels in comfort, practicality, and mileage. At the moment, I am confused between the Tata Sierra Diesel, Mahindra XUV 7XO Diesel, Renault Duster Diesel, and Kia Seltos Diesel.

The Mahindra XUV 7XO AX3 diesel-manual fits your brief best. It has the roomiest cabin of your list and is the only one with three-row seating. Of course, with the last row folded, its boot is generous for luggage. On the highway, it feels steady and calm, rides bumps well, and the diesel is refined and both, punchy and efficient. 

Ground clearance and its inherent toughness make it capable of tackling light trails and rough roads.

I currently own a 2021 Hyundai Creta Diesel, which has covered nearly 2 lakh km without any major issues. I am now planning to buy a new diesel car/SUV with a budget of around Rs. 18 lakh (ex-showroom). My usage is primarily long-distance highway driving. I have shortlisted the Mahindra XUV 7XO, Tata Sierra, Tata Harrier, Kia Seltos, and Hyundai Creta. Considering the current market and long-term ownership, which one would you recommend?

For your usage, the Mahindra XUV 7XO diesel is the best fit. You are doing very high mileage with long highway runs, so diesel efficiency and strong performance are the priorities. This Mahindra car is one of the most refined and powerful diesel SUVs in this price range, and it is also a very comfortable long-distance car with a spacious cabin - including a third row of seats - and a strong feature set. The Tata Harrier is also a good highway car with a strong diesel engine and a comfortable ride, but the 7XO is a more refined and better-rounded package overall. However, both these are in a higher segment, which means your budget will only get you a low- to mid-range variant. In the segment below, the Tata Sierra diesel is a newer product and looks very promising, but its diesel engine doesn't feel particularly strong considering its size and weight. The Hyundai Creta is just a facelifted version of your current car and hence won't feel as new, while the Seltos, though new and larger, uses the same engine as your Creta, and like the Sierra, doesn't feel as powerful given the SUV's size. Overall, the 7XO feels like the more premium and more complete product for your usage, but if you're not happy with the features on offer in your budget, try the Seltos instead.

I'm 36 years old and currently own a Kia Seltos petrol automatic. My annual running is around 10,000-11,000 km, with about 20% city driving and 80% long highway trips, typically covering 600-1,000 km in a single journey. I'm now looking to buy a 7-seater SUV and am confused between the Mahindra XUV 7XO diesel automatic and petrol automatic. I'm also wondering if I should consider the Mahindra XEV 9S, given the push towards EVs However, I feel that doing 800km one-way trips in an EV could be difficult, especially since the charging infrastructure still doesn't seem adequate. What would you recommend?

Go for the Mahindra XUV 7XO diesel automatic. Your usage pattern is very clear: 80% highway, long 600-1000 km trips, and around 10,000-11,000 km a year. This is exactly the kind of usage where a diesel engine makes the most sense. Moreover, the diesel engine of this Mahindra car is the superior one in the line-up; it is a strong highway performer and will be significantly more efficient than the petrol on long runs.The XEV 9S is a very capable and practical electric car. It offers good value for money, but as you've pointed out, for your kind of 800 km one-way trips it is simply not practical yet. Charging infrastructure is improving, but it is still not at a point where you can do these kinds of distances without significant planning and downtime. The XUV 7XO diesel automatic is the right tool for the job and will give you the best ownership experience for your usage.
