I own a Tata Altroz DCA Petrol and have been driving it for almost one year. It has completed 30,000 km. I want to upgrade to a diesel automatic and have shortlisted the Sierra and Curvv. I need your help for choosing the best one and even suggestions about other models.
Given your usage of 30,000 km in a year, a diesel automatic is the right move, and both the Tata Sierra and Tata Curvv are strong options. The Sierra is the better choice if you priorities space, comfort and a more premium cabin experience. It offers a larger, more comfortable rear seat, a more spacious boot and a more relaxed long-distance touring character. There's also a lot of new features and tech with the Sierra, though on the higher trims. The Curvv, appeals with its coupe like styling but the trade-off is that it is not as spacious or as comfortable for rear-seat passengers. Between the two, the Sierra is also likely to hold on to its resale value better and it is the one we would lean towards.

@autocar.india given the usage I would suggest going in for a Sierra EV. I am using Curvv EV for last 2 years and am happy with the performance of the car. It's a near zero maintenance car. As I can recall a old ad. Saying fill it shut it forget it. Its like same charge it drive it and to add more forget it(maintainence).
I drive around 6,000–7,000 km a year, but I'm not happy with the mileage of my Tata Altroz DCT. It averages only about 10 km/l, and with E20 petrol becoming more common, fuel costs are becoming even more challenging. What options or alternatives would you suggest?
@shashank12 being a EV user I strongly recommend going in for either Tata punch EV or a Tata Nexon EV..
If charging is not a challenge. And it’s a mix of city and highway, go for ev either of them. 30000 in a year is an ideal driving range to choose EV. The difference between diesel automatic and ev is minimal and savings would be immense considering travel distance
@arghyam856 Go with Tata Sierra 👍
