I am confused between sierra tgdi and thar roxx. My driving is 80pc highway 20 pc city. Main requirements are automatic and ample space in car. It should be fun to drive.

Both these are very compelling SUVs that score high on desirability and road presence, as well as on interior space, but also do things very differently from one another. The Thar Roxx has the larger and more powerful engines which, combined with its aggressively calibrated automatic gearboxes, delivery strong and instantaneous performance. 

The downside, however, is that fuel economy takes a huge nosedive, which might be an annoyance on your long highway journeys. Moreover, the engines are not very refined and can feel a little too highly strung when you aren't driving quickly. And finally, while it is fun to drive in off-road and perhaps dirt-road conditions, it feels relatively large and cumbersome on tarmac, thanks in part to its ladder-frame construction. 

The Tata Sierra T-GDi, then, proves to be the better choice for you overall, as its monocoque chassis and sharper steering make it a lot more fun on the road. While not quite as powerful as the Mahindra, its 160hp turbo-petrol has more than enough punch and its 6-speed automatic is smooth too. It's also the more comfortable and fuel-efficient of the two by far, which should help on your highway drives.

I have been driving a 2012 Ford EcoSport diesel with a manual transmission, and I am quite impressed with its performance. Since the fitness certificate (FC) renewal is due soon, I am planning to upgrade. I am specifically looking for a diesel manual SUV and have shortlisted the Tata Sierra and Tata Harrier. However, I am inclined towards the Harrier mainly for two reasons: Build quality The Fiat-sourced diesel engine That said, the Sierra appeals to me because of its design and features. I am comfortable with the Pure+ variant, but I am not convinced that a sunroof should be mandatory on higher variants. Could you please suggest which of these two would be the better option? Also, if there are any other alternatives, please let me know. My main priorities are build quality and ride comfort.

Given what you're looking for in your SUV, the Tata Sierra makes more sense than the Harrier for you. It will feel like a considerable upgrade from your Ford EcoSport Diesel MT, most notably in size and features. And yes, as you mentioned, its standout design is really one of its biggest selling points. The Harrier has a much stronger engine, though build quality isn't too far off, but the premium Tata Motors is asking over the Sierra, spec for spec, doesn't feel worth it when the latter is such a good package. The sunroof, unfortunately, has become an inescapable feature in modern cars, especially in these segments, and it's something that you'll just have to accept and not use if you want the rest of the features as well. Tata is known to update its models regularly and add new trim levels, and maybe it will introduce more variants that have the rest of the features minus the sunroof. All things considered, the Sierra represents far better value than the Harrier.

I am planning to buy a new petrol car with a manual gearbox. My budget is around ₹13 lakh. My usage will be 70% city and 30% highway. Could you please suggest SUV options within this budget?

With a daily running of around 50 to 60 km, a diesel automatic makes good sense as your monthly usage will easily justify the better fuel efficiency and relaxed nature of a diesel engine.Between the two options, the Kia Seltos diesel automatic is the better choice overall. The diesel engine is refined, and the 6-speed torque converter automatic is smooth and well-suited for normal city traffic as well as highway drives.The Tata Sierra is also a strong Midsize SUV with more cabin space. But its diesel engine is noticeably noisier and less refined than the Hyundai-Kia diesel. It is also over a lakh more expensive in comparable automatic variants.For your usage and preference for an automatic, the Seltos diesel automatic is the more balanced and sensible option thanks to its refinement, smooth gearbox and lower price.

I am confused between the Mahindra XUV 7XO AX5 and Mahindra XUV 7XO AX7 variants, as I prefer practicality over extra features. Alternatively, should I consider waiting for the Tata Sierra?

If you don't mind the additional spend, we'd recommend the Mahindra XUV 7XO in AX7 trim. Elements like its larger 18-inch alloy wheels and leatherette upholstery add greatly to the look and feel of things. While auto climate control, a 540-degree camera and front parking sensors are features you will appreciate every day. The Tata Sierra is not a like-for-like alternative to the Mahindra 7XO. The 7XO is larger, more powerful and also offers three rows of seating.Further, the 7XO is slightly pricier, too. Within Tata's range, the Tata Safari is an alternative to the 7XO.
