At the close of 1969, Renault launched its front-wheel drive R12. Now known as the "C-Engine", the "Cléon-Fonte" was installed, this time ahead of the driver. It was reworked to a displacement of producing and had a uniform spacing between the cylinders. Despite the engine's flexibility, it was not powerful enough to power the sporty versions of the R12 and Alpine Berlinetta. This version was installed in the R12 and R15 TL. Mated to a new front drive transaxle, the version of C-engine was now found under the hood of the R6, and later in the R5.
