Set to make its UK debut at the Goodwood Festival of Speed in June, the new model features Renault's Cup chassis and includes a limited-slip differential as standard.
The car has also received a power upgrade. One of the key features is an Akrapovic performance titanium exhaust system, which helps to increase output from the 2.0-litre turbocharged petrol engine from 261bhp to 271bhp (or 275hp). There's also 266lb ft of torque available, while Renault quotes fuel consumption at 37.7mpg alongside CO2 emissions of 174g/km.
The car is likely to be the model which Renault will use to tackle the sub eight-minute Nürburgring lap record for front-wheel drive cars, currently held by Seat at 7min 58.4sec and at an average speed of 96.8mph.
A performance Mégane was previously teased in a preview video in association with Akrapovic. Dubbed the Under 8 project, it is believed that Renault will attempt to take back the record from the Volkswagen Group in June.
Other performance enhancements to the model include optional adjustable Öhlins dampers and springs and performance Michelin tyres. New Renaultsport graphics also feature alongside optional 19-inch alloy wheels.
Inside, the Mégane 275 Trophy comes with leather and Alcantara trim, Recaro bucket seats with contrasting stitching and a new alloy gear knob.
Pricing and specification information will be confirmed closer to the car's launch, which is likely to be later this summer. The 275 Trophy is believed to be a run-out edition for the current Mégane before a new model arrives in 2015. Renault has confirmed the Trophy will go on sale in 20 countries, with the first deliveries scheduled for October.
