Hi Team, I am from Bangalore, and I am planning to buy Mahindra Thar Roxx AX7L Diesel AT 4x4 in October 2026, hoping to get festive offers. My annual running is around 12,000 km, with 70% of it on highways. If I use my car only on weekends in the city and occasionally (once every two months) for long highway drives, will that be enough to avoid DPF-related issues? With the upcoming Isobutanol fuel blending, do I need to be concerned? Are Mahindra diesel cars compliant with this fuel?

With 12,000km a year and 70% highway driving, you are actually the ideal diesel owner. The Thar Roxx AX7L Diesel AT 4x4 is a great choice for your usage pattern, and you should not be worried about DPF issues. The DPF system needs sustained higher exhaust temperatures to regenerate, and your regular highway runs will take care of that naturally. Even if you are only using the car on weekends in the city, as long as you are doing occasional long highway drives, the system will regenerate as intended. The real DPF problems tend to occur with cars that are used exclusively for short, low-speed city trips with no highway running.

On the isobutanol front, there is nothing to worry about. Isobutanol is being considered as a diesel blend, but it is not a major policy direction like E20 petrol. Mahindra diesel engines are designed to handle the fuel blends available in the market, and there is no evidence to suggest that isobutanol blends will cause any issues. The bigger concern with diesel ownership is always usage pattern, not fuel blends.

The Thar Roxx is a very capable and enjoyable SUV, but it is worth being aware of its limitations. It is not the most practical family car, and the ride can be a bit firm on broken roads. But for your usage pattern, it is a solid choice. If you are looking for a more practical alternative with similar diesel capability, the Mahindra XUV 7XO Diesel AT is worth considering. It offers a more comfortable ride, better practicality and the same strong diesel engine. But if you want the Thar Roxx for its character and off-road capability, your usage pattern supports that decision.

I need your suggestion on car. We live in Thane, and my commute every alternate day is around 12 km. Our budget is Rs. 20-25 lakhs, and we’re looking for an automatic car (petrol or EV). We also take 5-6-hour road trips once every 2-3 months. Currently, we drive a 2011 Hyundai i20 and are planning to upgrade. Which car would you recommend and why, considering comfort, reliability, running costs, safety, and after-sales service? Thanks!

Consider the Kia Seltos DCT. For a 12km commute and occasional 5-6-hour road trips, you will find it comfortable in the city, quick on the highway and easy to own long term. The latest-generation Seltos is larger than before, so feels spacious inside. The cabin is tech-laden and upmarket, and the ride quality has improved too. The turbo-petrol DCT has good performance for quick overtakes on the highway, and the DCT is responsive. The downside is that it can occasionally hesitate in the city, but with your short commute this shouldn't be a deal-breaker. Kia's service is also amongst the best in the business.If you want something larger, the Mahindra XUV 7XO petrol automatic is also a solid choice in your budget. It is a genuinely comfortable car with a spacious cabin, excellent ride quality and strong highway manners. The petrol engine is smooth and refined, and the automatic gearbox makes city driving effortless. Mahindra's service network is strong in Thane and Mumbai. The drawback is that the big petrol engine will be thirsty in the city.An electric car makes sense if you can charge at home and if there are fast chargers on your usual highway route. In that case, the Hyundai Creta Electric is a safe bet. It is well suited to your short daily commute and offers very low running costs. In our real-world testing, it managed an impressive 486km on a single charge in the city and 378km on the highway.Overall, the Seltos is the best balance of comfort, reliability, running costs and ownership experience for your needs.

I currently own a Honda Elevate (CVT). I have driven around 72k km so far, with a mix of daily commuting and frequent highway trips for work. I am now looking to upgrade. There is nothing wrong with the Elevate - it has been a solid car - but the CVT feels a bit too tame for me now. I am looking for a logical upgrade with significantly better performance than the Elevate. My requirements are an automatic transmission, and I am open to both petrol and electric options. What would you recommend?

Given your usage pattern of high daily running and frequent highway trips, the Honda Elevate has clearly done its job as a dependable and comfortable workhorse. That said, your need for a meaningful performance upgrade is understandable. The 1.5-litre naturally aspirated engine paired with the CVT is smooth and efficient, but it does start to feel underwhelming once you begin to prioritise performance and responsiveness.A logical step up on the ICE side would be the Mahindra XUV 7X0 petrol. Its 2.0-litre turbo-petrol engine with 200hp delivers a strong jump in performance, and the 6-speed automatic is far more engaging than a CVT. Overtakes are effortless, and it brings a sense of urgency that the Elevate simply cannot match. The trade-offs, however, are worth noting. It is a larger car, so it won’t feel as nimble or easy to manoeuvre in tight urban conditions, and fuel efficiency can drop into the mid-single digits, especially with enthusiastic driving.If you are open to going electric, the upgrade in performance becomes even more pronounced. The Tata Sierra EV stands out as a compelling option. Like the Elevate, it sits in the mid-size SUV space but offers significantly more performance and space. With a 0 - 100kph time of under 6 seconds, it delivers instant torque and strong, seamless acceleration, which will feel like a dramatic leap, particularly in city driving and quick overtakes. It is also shaping up to be a well-rounded EV with a usable real-world range and a ride quality suited to long highway runs.In both cases, you are looking at a clear step up in performance, but the choice really comes down to whether you want the familiarity and refuelling ease of petrol, or the instant performance and lower running costs of an electric car.
