Hi, I am currently using an i20 Active diesel and am looking for a change to an automatic. Could you please suggest a diesel automatic car, such as the Sierra, Creta, Seltos, or any other suitable option? My usage is around 20-30% in the city and 70-80% on long drives.
With 70-80% highway usage and a preference for a diesel automatic, the Kia Seltos diesel automatic is the most sensible upgrade from your i20 Active. The Seltos diesel is a good highway performer with a refined engine, a well-sorted automatic gearbox and a comfortable, premium cabin. The 1.5 diesel is very efficient too.
The Tata Sierra diesel automatic is a good alternative if you prioritise ride comfort, rear seat space and a large boot, but the Seltos is the more polished and proven product overall.
