•1wI’m planning to buy the Tata Harrier Hyperion (1.5L petrol), which was recently launched and costs around ₹23 lakh. I would like opinions on whether buying the petrol version at this price is a good decision. The 1.5-litre petrol engine is new and hasn’t been long-term tested in real-world conditions yet. Many reviewers say it isn’t underpowered, but I’m still concerned about real-world performance in situations like city traffic, highway overtakes, driving with the AC on, or with a fully loaded car. I also want to know the practical, real-world mileage (city and highway) that owners are actually getting, not just the claimed figures. Should I wait for more long-term reliability feedback before buying, or is it safe to purchase now? Alternatively, would it be wiser to choose the diesel version for proven reliability and better fuel efficiency? My main concerns are performance, real-world fuel efficiency, reliability of a newly launched engine, and whether paying ₹23 lakh for the petrol variant is justified.

Your concerns about Tata's 1.5-litre Hyperion engine being new are valid. If you are not in a hurry, it is advisable to wait a few months to see what buyers have to say about its reliability and efficiency. Do note that the same engine also powers the Tata Sierra, which is selling in huge numbers, so owner feedback should be coming soon.
That said, the Hyperion engine is one of Tata's best engines to date. During our first drive review, we found that performance was much better than the displacement suggests. It picks up speed effortlessly and feels grunty in city driving, and even on the highway, it does not run out of breath.
We also tried the same engine in the Tata Safari with six people on board and the AC on, and even then, performance was more than adequate. Real-world fuel efficiency will not be great, expect single digits in the city.
The diesel will offer better efficiency and is a more proven powerplant, and if you are driving huge mileages, then it is the better choice. However, performance is not as strong as the petrol.
If you are still concerned about reliability, we suggest you look at the Kia Seltos. The current generation has grown in size, resulting in a roomier interior, and the 1.5-litre TGDi petrol offers good performance and proven reliability. Before you decide, take test drives of both cars.

•6dI currently own a 2021 Hyundai Venue (iMT) Petrol. I usually travel to my hometown in Punjab once a month, and the rest of the time, I drive within the city. I am looking to buy an SUV with good aesthetics and build quality; the first car that comes to mind is the Tata Harrier. I was eagerly waiting for the petrol variant, and this year, that wish finally came true. I am planning to purchase the Fearless+ variant in white. However, considering Tata's reputation for manufacturing defects and resale value, should I stick with my choice, or would you suggest a better option, like a Mahindra XUV700?

•4dI would suggest wait for at least 6+ months for engine reliability and other concerns. We made that mistake when we got the Altroz turbo variant in April 2021, relatively new turbo engine at the time. There were issues where after 1 year the service team said engine is having issues and needs replacement, in spite of doing that (within warranty) it still gave problems. When we gave it for service around 2024 (due to persistent problems), Tata personnel said that our turbo variant is not being sold now and that a newer engine is being developed. Might sound scary and negative for you but bitter truth. Also, please ensure the service centres are professional and have a good knowledge because I always felt they were polite but not knowledgeable. Every time a new problem would arise when we give for service. Please keep reliability and service in mind before purchasing a Tata.

•4dI have a XUV 700 Diesel AX7 L 2022 with 80 K km. I want to buy a new SUV. I like the Tayron but it is costly. I am waiting for the Kodiaq facelift and Majestor, or an electric Mahindra SUV, or the facelift Fortuner—looking for the best option. If I need to stretch my budget, I might also consider. May be get some offers if i wait Please suggest
