Yes, the bumper is a two tone bumper in Renault Duster. Body colour on top and black at the bottom. Both Bumpers. In the top End, I have seen people getting a silver instead of the black at the bottom. I am not sure if that's an accessory available for us as well or only for the top end models as a factory fitted thing. Though Red and silver look good , but the black below doesn't look bad either. Rather, I feel the black would look better than the silver, of both of them are hit once.
PS is the German unit of power, 85 PS means that this car generates 85 PS of power and RXE is the name of the variant. It has got a 110 PS variant also which means that the engine is tuned to generate 110 PS of power.
The petrol variants of Duster and Terrano return a low mileage of around 12-13 kmpl, therefore it is advisable to go with diesel variants. Also, the K9K diesel engine performs better than the 1.6-litre petrol engine.
