With a new Megane coming, the Renaultsport version is on the way out - with two new models to mark the occasion

The new Cup-S includes air-con, cruise control and a 20-watt sound system with Bluetooth and auxiliary input as standard.

Renaultsport has unveiled a pair of high-spec run-out specials of the range-topping Renault Megane RS.

The new Cup-S includes air-con, cruise control and a 20-watt sound system with Bluetooth and auxiliary input as standard. It also makes use of the mechanical limited-slip differential, red Brembo brake calipers, firmer springs and dampers and stiffer anti-roll bar offered by the Cup Chassis Pack. With the uprated Cup chassis as standard, the 275 Cup-S costs from £23,935.

For an extra £2,000, the 275 Nav model adds an upgraded infotainment system, automatic lights and wipers, dual-zone climate control, keyless entry and rear parking sensors with a colour reversing camera. However, buyers can spec the 275 Nav with the Cup Chassis Pack for £1,350.

The extended wheel arches, F1-style front blade, rear diffuser and extended spoiler all form part of the aerodynamic styling that helps identify both versions from the standard Megane. Options for both cars include 19-inch wheels (£1,000) and Recaro leather seats (£1,300), while the Cup-S is available with a titanium exhaust (£2,500) and Öhlins adjustable dampers (£2,000). The Öhlins Road & Track adjustable dampers offer 20 positions at the front and 30 at the rear to help provide additional damping with heavy braking or upon hitting a bump.

The Megane 275 Cup-S and 275 Nav use the same 2.0-litre turbocharged petrol engine and six-speed manual gearbox. Both are capable of 0-62mph in 6.0 seconds, while they feature stop/start technology to claim 37.7mpg fuel economy and 174g/km CO2 emissions.
