The Renault Megane IV Sedan 1.5 Blue dCi (115 Hp) is a compact sedan produced by the French automaker Renault between 2018 and 2020. Part of the fourth generation of the Megane series, this model was primarily aimed at the European market, offering a practical and fuel-efficient option in the competitive C-segment. While not officially sold in the United States, the Megane IV represented Renault’s attempt to elevate its offerings in terms of design, technology, and driving experience. The sedan body style was particularly popular in markets where trunk space and traditional sedan aesthetics were preferred over hatchbacks.
Renault Megane IV Sedan 1.5 Blue dCi: An Overview
The Megane IV generation marked a significant departure from its predecessors, adopting a more refined and mature design language. The sedan variant, specifically, offered a more conventional profile compared to the hatchback and estate versions. The 1.5 Blue dCi engine option was a key component of Renault’s strategy to meet increasingly stringent European emission standards while providing acceptable performance and fuel economy. This engine was favored for its balance of power, efficiency, and relatively low running costs.
Engine & Performance
The Renault Megane IV Sedan 1.5 Blue dCi is powered by a 1.5-liter inline-four cylinder diesel engine, designated K9K 872. This engine produces 115 horsepower at 3750 rpm and 260 Nm (191.77 lb.-ft.) of torque at 2000 rpm. The engine utilizes a turbocharger with an intercooler and a diesel commonrail fuel injection system to optimize combustion and power delivery. The engine’s power-to-liter ratio is 78.7 hp/l. Acceleration from 0 to 100 km/h (0-62 mph) takes 11.1 seconds, while 0 to 60 mph is achieved in approximately 10.5 seconds. The vehicle has a maximum speed of 190 km/h (118.06 mph). Fuel economy is a strong point, with combined cycle figures ranging from 4.0 to 4.2 liters per 100 kilometers (58.8 – 56 US mpg, 70.6 – 67.3 UK mpg, 25 – 23.8 km/l). CO2 emissions are rated between 105 and 111 g/km, placing it within favorable emission brackets for European regulations. The engine is paired with a 6-speed manual transmission, driving the front wheels.
