The Renault Megane RS, the most powerful version of the Megane Coupe has a 2.0 turbo engine of 260 hp at 5,500 rpm and maximum torque of 340 Nm. 20 horse power increases with respect to the most powerful version of the previous generation, the Renault Megane R26.R. It has a six-speed manual box and ESC (stability control) off.

Available in two chassis: one Sport and Cup, the latter associated with a limited slip differential which distributes torque asymmetrically between its front wheels if necessary, to avoid losing traction. In the interior are sports seats with lateral reinforcement, analog tachometer with gear-changing witness (including an acoustic signal to show the best time), sports steering wheel with the thumb area and aluminum pedals. The decoration includes the Renault Sport logos in various places in the interior such as seats or at the bottom of the tachometer.

The Renault Megane Trophy concept features a Nissan-sourced 3.5-liter V6 mounted amidship like in the old Renaultsport Clio V6, but producing a prodigious 360hp driving through a six-speed sequential gearbox, all wrapped in a competition-grade body with more wing than the Concorde and more louvers than a Parisian museum tour. Currently the car is just a concept, but could end up going into limited production for a spec racing series
