Is the A-pillar of the newly launched Sierra any different from that of the Nexon and Harrier?

After BS6 emission norms came into effect in April 2020, all diesel cars in India, including the new Tata Sierra diesel, have to come with a Diesel Particulate Filter (DPF). There’s no exception to this, because the DPF is essential to meet BS6 particulate emission limits. So yes, the Sierra diesel will definitely have a DPF.What people usually mean when they say there’s “no DPF hassle” is that some cars are better calibrated and don’t throw up frequent warnings in normal use. A DPF works by trapping soot from the exhaust. Over time, this soot needs to be burned off in a process called regeneration. If you regularly drive at decent speeds for 20-30 minutes, the system cleans itself automatically. But if the car is used mostly for very short city runs where the engine doesn’t get fully warm, the soot can build up faster than it burns off. If regeneration cycles are repeatedly interrupted, the DPF can clog, triggering a warning light.From what we’ve seen, Tata’s recent diesel engines seem to be reasonably well-tuned, and we haven’t heard of widespread DPF issues like some early BS6 diesels from other brands. That said, no diesel with a DPF is completely immune; your driving pattern plays a big role.So if your usage includes regular, longer drives, the diesel should not be a problem. But if your driving is mainly short, stop-start city trips, a petrol will be the safer and more worry-free option.

Since you are looking for reliability and a trouble-free ownership, we would recommend the Skoda Kushaq over the Tata Sierra. The Sierra is an all-new car; thus, its reliability remains to be seen, though indications are good. The Kushaq is also a bit smaller than the Sierra, and this will help you in your city driving. For fewer highway rides, too, the Kushaq will offer up a good ride and handling balance and a secure feel on the highway.

Given your height, the Tata Sierra would be the better option among the rest. The Sierra gets a spacious cabin with good headroom and is a comfy cruiser over long drives thanks to the option of a diesel engine. Even the turbo-petrol is punchy, has good performance and is enjoyable to drive.The Seltos is also not too far behind, and while it isn't as roomy as the Sierra, the quality of the cabin is better, and it also gets a diesel engine that is quite nice on long trips. Where it falls behind the Sierra is the ride comfort, and hence we would recommend the Sierra for its all-round positives given your requirements.
