Renault Mégane R.S. trophy Alpha

The third generation of the Renault Megane R.S. is based on the 4th generation of the Mégane and was introduced at the 2017 Frankfurt Motor Show.[38] It is available in 3 trims: 280-Sport, 280-Cup and 300-Trophy. The Mégane R.S. is only available in 5-door hatchback bodystyle and was developed with the assistance of Renault F1 team driver Nico Hulkenberg.[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. 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. The infotainment system supports AppleCarPlay and Android Auto. An engine revving sound is played through the speakers when the driver opens the door of the car. Red stitching with RS badges are standard on the interior and the Trophy model adds an Alcantara-suede trim on the steering wheel. Recaro sports seats are optional equipment. Buyers have the choice to have a carbon fibre weave or an Alcantara trim.

The suspension system has struts up front and a torsion beam at the rear, but its front configuration has new geometry and retains Renault Sport's PerfoHub technology, which reduces kingpin angle offset and resists torque and bump steer. The system uses fluid-filled shock absorbers commonly found on rally cars on the lower end of the suspension struts and is called a damper within a damper system by the manufacturer. A sport suspension setup is optional which features electronic brake-actuated torque vectoring system.

The entry-level 280-Sport, features a torque-vectoring system of braking the inner wheels during a turn, to further improve turn-in; and a passive double damping suspension system.

The 280-Cup trim is similar to the 280 Sport trim, but adds a mechanical Torsen limited-slip-differential to the front wheels along with a 10% stiffer suspension setup. 19-inch wheels with Bridgestone tyres and lightweight brakes with aluminium hubs are optional.

The 300-Trophy is similar to the 280cup, but has even firmer suspension, and adds a higher-performance tune to the engine for more power.

four-wheel steering system called the "4Control" is standard on the Mégane RS which uses electronic actuators to turn the rear wheels synchronised with the front wheels.

Depending on the speed, the system may turn the rear wheels up to 2.7 degrees in the opposite direction to the front wheels or can turn the rear wheels up to 1 degree in the same direction as the front wheels.

Changeover happens at 60 km/h (37 mph) in Normal driving (all modes other than Race). The rear wheels are turned in the opposite direction to the front at up to 60 km/h (37 mph) and makes a tighter turning circle. 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.

In Race mode, changeover happens at a much higher 100 km/h (62 mph) allowing tighter cornering at higher speeds
