Sir, my driving is mainly on highways. I take outstation trips of approximately 1,000 km every 2-3 months. I am planning to buy the XUV 7XO automatic. Considering the 10-year validity for diesel vehicles and the DPF clogging issue due to low running, should I go for the diesel or petrol variant? Your opinion will be very helpful.

Pick the XUV 7XO diesel automatic for your use. Your driving is mostly highway and those 1000 km runs every 2-3 months give the exhaust enough steady heat to keep the DPF happy. The diesel also suits long trips better - it pulls stronger with a full family and luggage, and it will use less fuel than the petrol at cruising speeds, so your trip costs stay sensible.

If you live in Delhi-NCR, the 10-year cap on diesels is the real spoiler. In that one case, go petrol automatic to avoid resale and usage headaches later. Elsewhere in India, diesels are fine to keep beyond 10 years. The petrol is smoother in town but will feel thirstier on the highway and when pushed. With your pattern, the diesel’s torque and economy make the drive easier and cheaper, and your occasional long runs are exactly what prevent DPF trouble.

I am planning to buy a proper three-row diesel SUV, with a 6-seat configuration. I have shortlisted the top models of safari (ultra) and 7xo ax7L. Both have some advantages over the other in terms of features. I need expert feedback on driveability, driver comfort and overall comfort across all rows. I am thoroughly confused as to this decision. To add: This will be my second car. I have booked a Tiago EV for everyday office commute, and these will replace my Duster top-end diesel automatic. 7 seater I will use mainly with family on weekend trips and long trips Thanks in advance

Pick the Tata Safari 6-seat. It keeps the family happiest on long trips thanks to the comfiest ride and the most adult-friendly third row in this class. The suspension soaks bad roads, it stays settled at highway speeds, and the captain seats are wider with better thigh support. The third row sits a touch higher, has better recline and vents, so even two adults can manage a few hours without grumbling. Luggage space with all rows up is tight on both.Behind the wheel, the Safari is a relaxed mile muncher. The driving position is upright, visibility is great, seats are supportive, and the automatic is smooth. It is not the quickest to kick down, the engine is gruff and not as refined as the Mahindra, and there is some lag at low speeds, but on open roads, it cruises quietly. Coming from a Duster automatic, the ride upgrade is big.The Mahindra XUV 7XO AX7L is the sharper drive with a stronger diesel and snappier responses, and its ADAS feels better tuned. If you often climb hills fully loaded or love brisk overtakes, it makes life easier. For all-row comfort, choose the Safari.

I have a Grand Vitara Strong Hybrid, and I am extremely satisfied with its mileage (900-1000 km from 45 liters). However, I am losing the joy of driving. I migrated to this car after owning a Swift Dzire Diesel and an XL6. The mismatch between engine revs and acceleration is becoming unpleasant. Overtaking feels riskier, and even the brakes feel spongy. I have experienced a few unpleasant situations because of this. As a result, I have reduced my overall speed, making the safety of my family a bigger priority. But the driver in me is unhappy. Should I upgrade to the Duster Hybrid, the Hycross Hybrid, or the newly launched Sierra EV? Also, do diesel engines still make sense today?

From what you've described, the Grand Vitara Strong Hybrid has impressed you with its efficiency but left you wanting more from behind the wheel. If driving enjoyment is back on your priority list, the Duster Hybrid looks like the most natural upgrade. It is expected to offer a much more engaging driving experience while retaining the fuel efficiency benefits of a strong hybrid.The Toyota Innova HyCross Hybrid will certainly improve on comfort, refinement and performance, but it won't fundamentally change the character you're looking for. It is still geared towards relaxed family motoring rather than enthusiastic driving.The Tata Sierra EV is an interesting option and has now been launched. It promises strong performance, a premium cabin and a spacious interior. However, if the "driver in you" misses the involvement and confidence of your earlier diesel cars, we'd still wait to experience how the Duster Hybrid drives before making a decision.As for diesels, we don't think they should be ruled out altogether. With the right usage, they continue to make sense. However, given your appreciation for the fuel economy of your Grand Vitara and the direction the market is heading, we'd lean towards a strong hybrid rather than going back to diesel.
