Renault confirmed this news overnight, although it didn't state how many gears will be present on each gearbox.
Other details about the car have yet to be confirmed. A leak image of the car's posterior earlier this month revealed some of its styling details, including a more aggressive rear bumper with a diffuser-style element, and centrally mounted exhaust tips.
Spy photos from late last year also show that the car will feature a wider track, and flared wheel arches at both ends.
It's unknown at this stage which engine will power the new RS. One rumour suggests a version of the 1.8-litre turbo found in the new Alpine A110, while another says a 2.0-litre turbo will be employed.
The new Megane RS will be fully unveiled at the 2017 Frankfurt motor show in September, but won't go on sale in Europe until the first quarter of 2018.
With Formula One driver Nico Hulkenberg behind the wheel, the camouflaged Megane RS had its first official public outing at the Monaco Grand Prix, timed to celebrate the 40th anniversary of Renault's involvement with Formula One.
According to Renault, its "experts have once again used F1-derived technologies to produce a truly exceptional package of efficient aerodynamics, reliability, road holding and high performance".
