| Successor | EF series |
The CH-Type was a 90° V6 engine developed by Renault-Gordini for Renault's autosport activities. This François Castaing design was the predecessor of the famous EF series.
In 1972, after an agreement was reached with Elf, François Castaing, technical director of Renault Gordini, was given the go-ahead to build a 2-litre engine that could be used in a "sports" model and then in Formula 2. His team opted for a 90° V6, which was released in 1973 and was named the "type CH1" in honour of Claude Haardt, who had died in an accident a few months earlier.
