The Renault Megane IV RS Trophy 1.8 (300 Hp) is a high-performance hatchback produced by the French manufacturer Renault between 2018 and 2020. Representing the pinnacle of the fourth-generation Megane range, the RS Trophy was designed to deliver a focused driving experience, bridging the gap between road-legal performance and track capability. It primarily served the European market, where the hot hatchback segment is particularly popular, offering a compelling alternative to rivals like the Volkswagen Golf GTI and Ford Focus ST. While not officially sold in the United States, its engineering and performance characteristics are noteworthy within the broader context of performance vehicle development.
Renault Megane IV RS Trophy: A Performance Overview
The Megane IV RS Trophy builds upon the foundation of the standard Megane IV, a compact family car known for its practicality and modern design. However, the RS Trophy variant receives significant upgrades to its powertrain, chassis, and aerodynamics, transforming it into a serious performance machine. It’s positioned as a more extreme version of the already capable Megane RS, offering increased power, enhanced handling, and a more aggressive aesthetic. The “Trophy” designation signifies Renault Sport’s commitment to delivering a track-focused experience, evidenced by features like a limited-slip differential and upgraded braking system.
Engine & Performance
At the heart of the Megane IV RS Trophy lies a 1.8-liter turbocharged inline-four cylinder engine, designated M5P 404. This engine produces 300 horsepower and 400 Newton-meters (295 lb-ft) of torque. The engine utilizes direct fuel injection and an intercooled turbocharger to maximize power output and efficiency. The power-to-weight ratio of 4.7 kg/Hp and torque-to-weight ratio of 3.5 kg/Nm contribute to its responsive acceleration. The engine’s 166.9 horsepower per liter demonstrates a high degree of specific output. Coupled with a six-speed manual transmission, the RS Trophy can accelerate from 0 to 100 km/h (0-62 mph) in 5.7 seconds, and 0 to 60 mph in a calculated 5.4 seconds. Its top speed is electronically limited to 260 km/h (161.56 mph). Fuel consumption is rated at 8.1 liters per 100 kilometers (29 US mpg), with CO2 emissions of 183 g/km, meeting Euro 6d emission standards.
Design & Features
The Renault Megane IV RS Trophy is a five-door hatchback with seating for five passengers. Its exterior design is characterized by aggressive styling cues, including a more prominent front bumper with larger air intakes, wider wheel arches, and a rear diffuser. These aerodynamic enhancements contribute to improved downforce and stability at high speeds. The car rides on 19-inch alloy wheels shod with 245/35 R19 tires, providing ample grip. Inside, the RS Trophy features sport seats with enhanced bolstering, a unique steering wheel, and aluminum pedals. The interior prioritizes a driver-focused experience. Safety features include ABS (Anti-lock Braking System) and ventilated disc brakes on all four wheels. The car’s turning circle is 10.3 meters (33.79 ft). The Trophy model also benefits from a Torsen limited-slip differential, enhancing traction and cornering performance.
