The 2.0-liter 16-valve Renault F7R engine was introduced in 1994 as a sports engine for the company’s racing division. But civil modifications were also equipped with it, for example, the top versions of the first Megane.
Having exhausted the possibilities for upgrading the 1.8-liter F7P engine, the engineers squandered it to 2 liters. Moreover, they increased not only the diameter of the piston, but also its stroke, completely preserving the riding character of the donor.
Otherwise, these units are very similar. So we have a cast-iron block, an aluminum 16-valve head, hydraulic lifters, an advanced intake manifold, a timing belt drive, and X-shaped lightweight pistons.
The differences are a different exhaust, a two-liter 4-2-1 spider, larger valves, its own oil cooler, control unit and other little things.
The engine was installed on:
- Renault Clio 1 (X57) in 1994 – 1997;
- Renault Megane 1 (X64) in 1995 – 1999.

|Cylinder bore, mm||82.7|
|Piston stroke, mm||93|

|Engine lifespan, km||~300 000|
Disadvantages of the Renault F7R engine
- Unreliable ignition coils are the main cause of engine tripping. And since they are made in a single module, if one breaks down, a block of four will have to be changed entirely.
- If the car stalls on the move, first of all it is worth checking the crankshaft position sensor, most often it is he who is to blame.
- Unstable operation of the motor is usually associated with the failure of the MAP sensor or severe contamination of the throttle.
- The weak point of this power unit is oil leaks, especially often it oozes through the crankshaft oil seal.
