The Tata Sierra is a good upgrade from your Hyundai i20. You will enjoy the space and features inside. The diesel engine is not very punchy, but it's a tired and tested unit and it uses a lean NOx trap to manage emissions so you do not have to worry about the diesel particulate filter clogging as you do in other diesels in the segment - which tend to clog if your driving is all typically short runs (less than 60kms) in the city.
Besides the Tata Sierra, it's hard to figure out what you would like without knowing specifics, such as the importance of rear seat space, features, engine performance, etc. However, you can also consider the new Kia Seltos, which is a very good all-rounder. However, bear in mind, since you are switching to diesel, your running at least once a week should include a long drive with speeds around 60-70kph to avoid potential DPF clogging issues.
