In the Renault lineup, there are charged R.S. versions, particularly hatchbacks, including the budget Sandero RS 2.0 Racing Spirit. However, despite the overwhelming popularity of the Duster, the French do not make a charged Duster RS. Nonetheless, there are owners of this budget crossover who have not been frugal on the tuning, giving it a sporty appearance.
In general, what the Duster RS could have been if it was released as a charged version by Renault Sport and/or not for off-road, but for good roads. And even with air suspension!
