The Mégane II RS was available in three-door and five-door hatchback versions, both with the same engine and was built at Renault's Dieppe factory by using body shells made in Palencia, Spain.

[4] In a 2004 road test by Mexican car magazine Automóvil Panamericano, the engine developed a peak output of 247 hp (184 kW; 250 PS).

Other features include automatic double optic headlights, 18-inch alloy wheels, air conditioning, ABS with EBD and electronic stability control.

The facelifted model introduced new safety features and minor exterior changes such as new tapered headlights, a revised front grille and bumpers along with translucent taillights.

It incorporates the improved version of the Cup Chassis package now with a limited slip differential fitted for the first time in addition to 18-inch Anthracite spoked alloy wheels with Michelin Pilot Sport 2 235/40 R18 tires, Brembo front and rear red brake calipers and an increased brake master cylinder diameter, plus revised stiffened steering.

Other features include a sport exhaust, Recaro seats, climate control, 4x15-watt RDS radio single CD/MP3 player with 6 speakers, Renault F1 decals, numbered plaque, limited slip differential and a rear spoiler.

New parts include new front springs (14 mm/100 kg), new rear springs (16.2 mm/100 kg), recalibrated shock absorber settings, grooved brake discs, new alloy wheels are fitted with a different offset increasing the track by 4 mm (0.2 in), optional Toyo Proxes R888 225/40R18 tyres (Michelin Pilot Sport 2 235/40R18 standard) and stiffer lower arm bushes.

[14] The Megane Renault Sport 250 features a 2.0-litre twin-scroll turbo 4-cylinder F4Rt engine rated at 247 bhp (184 kW; 250 PS) at 5,500 rpm and 340 N⋅m (251 lb⋅ft) of torque at 3,000 rpm with a 6-speed manual gearbox, Brembo front brakes, front splitter, extended sills and wheel arches, rear diffuser with central exhaust pipe, and 18-inch alloy wheels wearing 225/40R18 tyres.

The 250 Cup variant contains a number of sharpened performance features including a stiffer chassis, track focused suspension, a limited slip differential and a slightly lighter gross weight.

A Cup Trophée model was offered above that, which included a number of extra inclusions like fabric Recaro Sportster CS seats, proximity key replacing remote key, tyre pressure monitoring, upgraded stereo, grey body highlights instead of black (except for Lunar Grey), electrically folding mirrors, and the 19-inch Steev wheels.

but due to modifications such as a new air intake and higher turbo pressure (from 1.15 to 1.35 bar (16.7 to 19.6 psi)) it gains an extra 15 hp, increasing the power output to 261 bhp (195 kW; 265 PS) and 360 N⋅m (266 lb⋅ft) of torque.

It comes in a model-specific metallic yellow (Jaune Sirius) but is also available in more low-key colors such as white (Blanc Glacier), black (Noir Étoilé) and gray (Gris Cassiopée).

The car was a result of Renault winning a tender from the Gendarmerie National for a new high speed pursuit vehicle with a power output requirement of 261 bhp.

The new exterior package introduced on the 265 was the 'Red Design Pack' which includes red striping on front blade, rear diffuser and side protection mouldings, rear parking camera with front parking sensors, Visio System lane departure warning and auto high/low beam headlights.

Other features include Red Bull decals (with additional chequiered flag decal for the RB7 Edition), 19-inch Steeve wheels, red Brembo brake calipers, limited slip differential, Bridgestone Potenza tyres, leather Recaro bucket seats and a Renault Sport monitor which displays vital track day information G-Force and laptime data.

The car was only available in a single trim with an optional cup chassis package which included limited slip differential and a firmer suspension setup.

[26][27] In response to SEAT setting a new record for a Front-wheel drive production car at the Nürburgring race track with the Leon Cupra 280 at 7:58.4, Renault developed the 275 Trophy-R to retake the title a few weeks after.

Other changes include Öhlins dampers with Allevard composite coil springs and 19-inch Speedline Turini wheels with Michelin Pilot Sport Cup 2 tyres.

Other exterior features include a panoramic roof, 19-inch wheels, red Brembo brake calipers, and bixenon directional headlamps.

[32] 2012 Australian GP Edition – This model featured a gloss black exterior colour with matching 19-inch Steev alloy wheels along with contrasting red Brembo brake calipers.

It was built to cebrate Renault's lap record at the Nurburgring and only came in Liquid Yellow and Pearl White exterior colours.

Other changes included 19-inch gloss black alloy wheels with red rim, leather trimmed Recaro front bucket seats and Bridgestone Potenza RE050A tyres also used by record setting car.

The interior was equipped with basic features such as cloth seats, manual air conditioning, parking sensors and Bluetooth phone connectivity along with six airbags.

The variant also features Renault Sport Monitor System which lets the driver choose between various driving modes with additional settings for throttle response.

The Trophy features a composite body with a space frame chassis and a mid-mounted 3.5-litre Nissan-Renault V6 engine rated at 326 hp (243 kW; 331 PS) and 390 N⋅m (288 lb⋅ft) mated to a 6-speed sequential transmission driving the rear wheels.

[39] All feature a similar turbocharged 1.8-litre inline-4 engine (to a varying rate of tune) shared with the Alpine A110, and as standard a four-wheel steering system to improve handling, though this was removed to save weight in the Trophy-R. Five selectable drive-modes are available, namely Comfort, Neutral, Sport, Race and Personal (which is a customisable driving mode).

The interior features a portrait style infotainment system and red graphical display on the digital tachometer flanked by analogue fuel and water temperature gauges.

Red stitching with RS badges are standard on the interior and the Trophy model adds an Alcantara-suede trim on the steering wheel.

The 300 Trophy is similar to the 280 Cup, but has even firmer suspension, a lightweight DESS (Dual-Energy Storage System) battery, a different cylinder head and turbocharger with a higher-performance engine tune for more power (221 kw).

When the speedo swings past 60, they turn in the same direction as the fronts to virtually extend the wheelbase for better motorway driving stability.
