One important point up front: we haven’t yet driven the 1.0-litre engine in the Renault Duster itself, but we have experienced this engine in the Renault Kiger and Nissan Magnite, where it feels more than adequate in both city and highway use. However, since the Duster is a larger and heavier car, it is unlikely to feel as effortless, especially under load or on inclines. The 1.0 TCe 100 is the more economical option. For mostly city use and plain terrain, it will do the job and should be slightly more fuel efficient, which helps keep running costs in check.
The 1.3 TCe 160, however, is a big step up. It will offer much stronger pulling power, which you will clearly feel with a full load, on highways and on hilly roads. It will make the car feel more effortless and relaxed to drive, with fewer gear changes and better overtaking ability.
If you want strong performance, better pulling power and a more relaxed drive, the 1.3 TCe 160 is worth the extra Rs 1.4 lakh.
