This 1.4L inline 4-cylinder engine is widely used in Renault models like the Clio and Megane, offering a perfect balance between power and economy.

It typically produces around 120–140 horsepower with torque in the range of 190–220 Nm, making it ideal for both city driving and highway performance.

⚠️ External components such as alternator, starter motor, and AC compressor may need to be transferred from your existing engine.
