This list came from the The Douvrin PRV Six-Engine Association. Interesting story. Best Wishes, Michael <<Greetings to all our Members! I have spent some time researching the very early stages of the PRV V6 engine development. Piero Casucci tells in his book "Lancia Thema" that the PRV V6 design was most of all influenced by the development of the Citroen SM Maserati engine. Piero Casucci, of course, is Italian by nationality, but in my opinion he is anyway a very reliable source of information even in this case. The Citroen SM engine was developed by Giulio Alfieri who worked for Maserati, after Citroen acquired the ownership of the Maserati marque. Maserati had a good reputation in France, and now it had even a French owner. Therefore, also in my opinion, it seems quite natural that the SM project led to another "French connection", with the Peugeot-Renault axle (Volvo later involved) who had the aim of developing a French performance engine. We must keep in mind, however, that there is very strong evidence about the PRV V6 project being originally a V8 one! So the question remains, what was the original model that Peugeot and Renault used as an example for a V8 engine ? Logically thinking, this V8 would have been the Maserati Mexico 4,2 litre V8 from which the Citroen SM V6 was developed. Please comment this information if you have anything to add or any serious opinions. Best Regards, Mr. Pertti Tapio Mäkelä The Douvrin PRV Six-Engine Association>>
