Q. Which variant of Renault Duster is better 85 PS or 110 PS power wise?

110 ps taller 6 speed gearbox great on highways and in city too..85 ps is a good option with a less price.110 ps has turbo lag (mind that after second gear at low rpms)if there is no highway use prefer 85 ps

As per my personal experience 85 PS is best for city and highway. No turbo log no frequent gear shifting. Further Clutch plate, diesel filter and some other parts of 85 PS is cheap compared to 110 PS.

Definitely the 110PS variant is more powerful than the 85PS.Means it will have a better acceleration rate and a little more maximum speed.
