I currently own a 2022 Mahindra XUV 700 Petrol AT, and I usually fill it with regular petrol. I’m considering switching to higher‑octane fuel. Do you recommend using premium fuel for the mStallion engine? If yes, what octane rating should I use?

There is no real benefit in using high-octane fuel now that E20 petrol has been introduced from April 2025. Ethanol increases octane rating, and with the shift from E10 to E20, the effective octane rating has increased from 91 to 95 across the country.
The 2.0 litre TGDI mStallion engine in your XUV700, or the XUV 7XO as it is called post the facelift, has a compression ratio of 9.5:1, which is perfectly suited to 95 octane fuel. Using anything higher offers no tangible advantage and would simply be unnecessary overkill.

I own a 2017 Skoda Yeti from the last batch, which has completed 1,30,000 km on the odometer. It has been very well maintained, and I have recently done a major service, including the replacement of the timing belt and water pump. However, I have started feeling the urge to upgrade. Would it be a good idea to upgrade to a new car under ₹35 lakh, preferably a diesel automatic, considering my daily running of around 80 km on the highway? Or would it make more sense to retain the Yeti for a few more years?

We understand your love for your Skoda Yeti. It's a superbly engineered car which is very well suited to Indian conditions. Your car with over 1,30,000km on the odometer would likely be the most used Yeti in India! While care and periodic maintenance will keep the Yeti running, issues are bound to crop up every now and then. Hence, there is a case for a new vehicle. The best bet in your budget is the Mahindra XUV 7XO diesel-AT in fully loaded AX7 T form. It's got a strong diesel engine, smooth gearbox, and, as someone used to a Yeti, you'll appreciate the ride and handling balance too. The XUV 7XO is also packed with lots of tech and features, which really make it feel like a good value even at its price.Alternatively, you could consider the Jeep Compass, which, like your Yeti, comes across as a solidly engineered product. It has been around for quite some time now, but there's a toughness that shines through, and ride and handling are also really good. The 9-speed gearbox dulls some of the engine's performance, though. The Compass is also not very large for its price - something that also worked against the Yeti.

I currently own a Renault Duster and have been driving it since 2016. As I am planning to upgrade, I am looking for an automatic petrol SUV with an on-road budget of around ₹30 lakh. I live in Pune, and my daily commute is about 40 km (home-office-home). Around 60% of this drive is on the highway, although traffic in the evenings is usually slow.I would prefer an SUV with good boot space, strong ground clearance, good safety, and modern features. Could you please suggest which car would be the best option for my requirements?

At this budget, your best bet is the Mahindra XUV 7XO. It's spacious, comfortable and loaded with features, and will feel like a worthy upgrade to your Renault Duster. Your daily usage isn't that much, but since a large chunk of it is on the highway, you'll appreciate the XUV 7XO's stability, ground clearance and good ride quality. And as safety is a priority, you'll be happy to know it comes with a long list of standard safety kit, and has been given a 5-star crash test rating by Bharat NCAP. Whether you choose the petrol or the diesel is really a matter of preference, given your limited usage, and both come with smooth automatic gearboxes to help make your commute a little less tiresome.

Which mid-size SUV has a spacious rear seat?

Among mid-size SUVs, there are several with genuinely spacious and comfortable rear seats, but the best choice depends a bit on your budget and whether you’ll be chauffeur-driven or driving yourself.At the top end of the segment, the Mahindra XUV 7XO offers a very roomy and supportive rear bench with good legroom and headroom The electric Mahindra XEV 9S goes a step further with a sliding middle row, which lets you prioritise either legroom or boot space as needed, and this adjustability makes a big difference if you often have adults in the back or use a child seat.Lower down the price band, the Tata Sierra stands out for rear seat comfort. It has an exceptionally accommodating back seat with loads of legroom, a natural, slightly elevated seating position and well-cushioned seats that give you that “loungy” feel. It’s the kind of rear bench you can spend hours in without feeling tired.If outright rear space is your priority, though, the MG Hector is still the benchmark. Its rear seat is very wide, so three passengers can sit comfortably, and the flat-ish floor helps as well. The low step-in height makes it easy for elderly passengers to get in and out, and the soft suspension setup does a good job of smoothing out broken urban roads. These traits make the Hector particularly well-suited if the car will be largely chauffeur-driven and rear seat comfort is at the top of your wish list.
