At the front, a Formula One-style front blade finished in gunmetal grey and chequered flag LED fog lamps have been incorporated into the bumper design.
Meanwhile, behind the front wheel arches are large extractor vents that help suck turbulent air out reducing lift at high speed. The standard auto makes do with an open differential, but if you spec the more focused "Cup" chassis, you get a Torsen limited-slip differential. Renault has also added a new paint colour called Tonic Orange to the options list.
Laurens van den Acker, Renault's Senior Vice President, Corporate Design said "no longer can we think of vehicle design in isolation from the ecosystem surrounding us, or from the evolution of major changes like electric energy use, connected and autonomous drive technologies that influence our lives as we move from place to place".
Renault is set to release full performance figures later today but, thanks to claimed "class-leading" power-to-weight ratio, the small hot hatch should hit 100km/h in 5.8 seconds and top out at more than 250km/h.
"Fitting four-wheel steering was the biggest decision we had to make", Patrice Ratti, Renault Sport boss, told journalists.
The new Megane will be offered with two chassis setups: Sport or Cup. Performance should be enhanced by the 4CONTROL four-wheel steering. An RS Drive button provides a shortcut to Sport and Race modes.
Renault's hot hatches always perform well. The system allows the rear wheels to turn up to 2.7 degrees, delivering more stability and agility. Upgrades on the Megane R.S. Cup include a Torsen limited-slip differential and suspension tuned for "optimal handling efficiency on all types of road". Order books for Renault Megane RS will open in spring 2018. "The cabin can either be specced with a "'carbon fibre weave" finish, or festooned with Alcantara. As described in the company, all auxiliary electronic AIDS of the vehicle can be switched off via the multimedia system R-Link 2.
The Megane RS goes on sale in United Kingdom in the spring, and although official prices are yet to be confirmed, a starting price below £30,000 is expected.
The new Renault Megane RS shares its engine with the Alpine.
