The Renault Sport Mégane Trophy is a racing version of the Mégane RS, which includes a tube frame chassis with glass fibre body keeping just visual resemblance to the road legal Mégane. The RS Trophy uses the considerably modified Renault Vel Satis V4Y 3.5-litre V6 engine (which is a rebadged VQ35DE of the Nissan VQ engine family) featuring a dry sump lubrication system rated at 325 hp (242 kW; 330 PS) at 7,000 rpm and 390 N⋅m (288 lb⋅ft) at 4,500 rpm. The engine together with Sadev 6-speed sequential gearbox is placed longitudinally behind the cockpit.
The Renault Sport Mégane Trophy is not road legal and was intended to be used for competition only in the Renault Eurocup, but cars also race in events like the Belgian Touring Car Series and the Dubai 24 Hour.
The second generation was shown at the 2008 Paris Motor Show and was used in the Renault Eurocup starting from the 2009 season.
