Renault Clio's original lines have been revised with the accent on more athletic, telltale curves. The more aggressive front end incorporates an F1-type aerodynamic splitter and a generously-sized, low-positioned air intake, the mission of which is to cool the naturally-aspirated 2.0 16V engine (147.5kW/203hp). The sills, extractors and wider front and rear wings all serve to highlight the sporty calling of Clio Renault Sport which features Renault Sport's new styling identity cues with the Renault Sport Design Pack's two-tone colour scheme based on a choice of Gloss Black or Cold Metal Grey for the front bumper mouldings, exterior mirror housings and diffuser. At the rear, the twin exhaust tailpipes have been incorporated into the diffuser.

The model's sporting pedigree is confirmed by details such as the aluminium pedal covers and footrest, as well as by the perforated leather steering wheel with visible stitching and yellow centre-point marker. The yellow rev-counter includes an audible and visible Formula 1-style gearshift indicator to help optimize gear changes.

The Luxe and Cup versions of Clio Renault Sport are powered by the same normally-aspirated 2.0 16V engine (F4R RS). With a specific power output of more than 100hp/litre, this powerplant delivers an extremely high standard of performance for the hot hatch segment. In addition to the gains achieved at low revs, peak power has been increased by 2.5kW to 147.5kW (203hp) at 7,100rpm. Meanwhile, the torque boasted by Clio Renault Sport has been upped 20 per cent thanks to a new cylinder head, continuously variable intake valve timing and fine-tuning of the engine mapping.
