I am planning to buy a new SUV. I am considering the Creta or Seltos, and if I look at a 7-seater, the XUV 7XO or Scorpio N. Which is better between the Creta and Seltos, and between the Scorpio N and XUV 7XO?

Between the Hyundai Creta and Seltos, both cars offer the same engine and gearbox options. However, the Kia Seltos is all-new, features a larger body, more cabin space, and feels a notch up in quality as well.Your choice of seven-seaters isn’t as similar. The Mahindra Scorpio N is built on a body-on-frame chassis, which means it's very tough and can take a lot of beating, but it's nowhere near as comfortable as the XUV 7XO, which has a larger cabin and far more features.The biggest difference between the two is ride quality: the Scorpio N, a tall-riding SUV, rocks from side to side and is quite bumpy on rough roads. In contrast, the Mahindra XUV 7XO, with its updated suspension, feels incredibly refined and comfortable. It softens the bumps and feels very stable at high speeds. So if you don’t travel on really bad roads, the XUV 7XO is a far better option.

I am planning to buy the XEV 9e Pack 3 with the 79kWh battery. I am a heavy-footed driver and tend to drive aggressively. Performance is the main reason I am considering this car. However, I saw a review where the XEV 9e was driven at around 170kph for about eight minutes, after which the power dropped by 14% from the initial. If performance is my priority and I am not concerned about range, should I still go for it? I am scared that it may underperform a lot after driving at excessive speeds for a long time.

Don’t be alarmed by the video you saw. All electric cars discharge very fast when driven at speed. And a fast discharge also heats up the battery and motor, so to protect the hardware, the battery management system (BMS) cuts the power, which explains the 14% drop you noticed.Because of aerodynamic drag, speed is the biggest enemy of range, and there is an exponential drop the faster you go. For example, if you drive at 160-170kph, the batteries will discharge 2.5 to 3 times faster than if you were driving at 90-100kph.Even EVs with large batteries can lose charge at the rate of 1-2% per minute with hard and sustained high-speed driving.So if all you want is performance and don’t care about range, the Mahindra XEV 9e in Race mode is very quick for short bursts of acceleration to overtake and fast highway runs. But no EV will give you full peak power indefinitely at extreme speeds.It all depends on how the BMS is calibrated, but after sustained high-speed driving, expect a drop in power, which is normal for an EV and not a flaw of the 9e specifically.

I own a hybrid Grand Vitara and would like to know whether the electric cells in a hybrid also serve the needs of air-conditioning and other electrical peripherals. If there is a separate battery for these functions, does it get charged automatically by the engine when the car is in idle condition?

In the Maruti Suzuki Grand Vitara hybrid, the air-con and most electrical systems are powered by the main hybrid battery. There is also a small 12-volt battery, but it only runs basic electricals and electronics like the dashboard and locking.When you are stopped with the air-con on, the car uses the hybrid battery first. If that battery level drops, the petrol engine automatically starts. The engine then generates power to recharge the main battery and shuts off again when the battery is fully charged.

I am planning to purchase a new automatic car in the next 6 months, with an on-road budget of ₹20 lakh in Bangalore. I am preferably looking for an SUV with a 5-star safety rating and a large boot of around 500 litres. I like the Tata Sierra, but am wary of its new naturally aspirated petrol engine paired with a DCA automatic. My annual running is low at around 7,000km, with about 30% highway usage. I understand that my usage does not ideally suit a diesel, but I am still interested due to the mileage and torque benefits. My main concern with diesel engines is DPF issues, given my low running. Do the Sierra or other Tata diesel cars face DPF issues with limited highway use? Are there any better alternatives that suit my requirements?

The Tata Sierra is a very appealing car and definitely worth considering. We have driven the 1.5-litre naturally aspirated petrol with the DCA automatic, and while it is smooth, it feels sluggish, especially on the highway. Quick overtakes of fast-moving trucks require planning and effort.Given that around 30% of your driving is on highways, we would recommend a diesel car instead. It is torquey, has a strong mid-range, and is much better suited to overtaking and relaxed long-distance driving.Regarding DPF concerns, the issue is not low annual mileage but driving pattern. Diesel particulate filters need the car to be driven at steady speeds for some time to clean themselves. Since you do have regular highway usage, your driving pattern should allow the DPF to regenerate properly, making clogging unlikely in normal use.
