The 2013 Megane Coupe GT has received a specific Malta Blue color, which was the only one available.
The front bumper has been redesigned for a sportier look. The lower grille and the white headlight surrounds are specific to the GT and GT-Line cars, as are the black headlight masks.
A new set of light-alloy-wheels was available for the Coupe GT, fitted with 225/40 R18 tires. Some aluminum and dark themes were available for the vehicle as well.

Inside, in the dashboard, there is a new analog tachometer besides the digital speedometer. The white background and a very visible red zone suggest a sportier vehicle, but the overall interior updates are not so obvious. Some sportier seats with better lateral support and new color for the seatbelts were fitted as well.

For the Coupe GT Renault offered two specific engines, both with a 2.0-liter displacement and both turbocharged. The gasoline version offered 220 hp and 340 Nm (250 lb-ft) of torque, while the diesel unit had 165 hp and 380 Nm (280 lb-ft) of torque. For both engines, the only transmission available was a six-speed manual unit. Performance was good, with a 0 to 100 kph (0-62 mph) sprint in 8.8 seconds for the diesel and two seconds faster for the gasoline version. Top speed was good for both variants, with 240 kph (150 mph) for the gasoline and 215 kph (133 mph) for the diesel.
