    I'll take the definitive answer when some of the French members of Club Alpine respond to me query. One of them is liekly to even give us engine numbers fomr his car to prove it

    At least no one can say we haven't done our homework.
    I have here and old 1985 portuguese motorsport annuary. It confirms the 1597 number but, as you said, it is no more a question of confirmation of numbers cause we all know now that all those engines probably existed.

    That friend of yours answer will be accepted as the official tie-breaker!

    Have a nice weekend!

    Renault 5 Turbo: History

    Tour de Corse, May 1985:
    Maxi 5 Turbo A wizard at rallies and a virtuoso on the racetrack, the Renault 5 Turbo is still an exceptional vehicle more than 20 years after it was first produced. This thoroughbred had a thrusting, athletic look and was the first French car running on petrol to be fitted with a turbocharger. Glowing references that gave it direct access to the world of legendary cars.

    An idea... and the will to make it work

    As well as the convincing result of a technical demonstration, the Renault 5 Turbo was the culmination of a tale of extraordinary human endeavour. It was the brainchild of Jean Terramorsi, deputy director of the Product Planning Department who was in charge of small-scale production models, and his assistant Henry Lherm in 1976. They wanted to bring out a more powerful version of the best-selling Renault 5, which was then being produced at a rate of 2,400 units per day, by fitting it with a turbocharger. Dubbed project number 822, the assignment would take four years to complete. Senior management gave the go-ahead because they believed it was important to come up with a successor to the Renault 8 Gordini and the Alpine Berlinette.

    The specifications

    Jean Terramorsi died later in 1976 but his project lived on. The Renault Sport engineers got down to the task of designing the turbo engine, while styling was entrusted to the Renault Alpine company. The specifications were extremely detailed. They stated that the Renault 5 Turbo must be "a powerful, easy-to-drive vehicle with excellent roadholding, capable of shining on the racing circuits with only a small number of alterations". Other requirements included a 1.4-litre turbocharged engine, five-speed gearbox, maximum weight of 950kg, substantial comfort, good soundproofing and an overall appearance similar to that of the Renault 5. It was also quite a challenge to design a racing car on which a roadgoing model aimed at the general public would be based. That was another first.



    Monte Carlo rally, January
    1981: Renault 5 Turbo First outing


    March 9, 1978: late at night, as about 20 people gathered at a racetrack near Arques-la-Bataille, not far from Dieppe, a growl was heard. It came from the first prototype of the Renault 5 Turbo, which immediately got off to a good start. Among the group were GÚrard Larrousse, head of Renault Sport, and Michel TÚtu, an excellent all-round engineer who provided the technical input for the Renault 5 Turbo.
    Further tests and adjustments were carried out. Aluminium put in an appearance on the doors and tailgate, and the Garrett company was selected to supply the turbo.

    Unveiling in Paris and on to victory

    The new car was introduced to the general public at the 1978 Paris Motor Show. Visitors were immediately won over by its compact, dynamic look, strapping wings, and unusual interior treatment. But the Renault 5 Turbo was anything but a showroom car. It was happier eating up the miles on the open road or getting to grips with the rally circuits. It made its racing dÚbut in the Tour of Italy in 1979. Next came the 1980 Tour of Corsica, where the car, skilfully driven by Jean Ragnotti, would have been hard to beat but for a mechanical fault. Its first victory came at the Monte Carlo rally in 1981 - only its fourth race.




    Monaco, May 1982:
    Renault 5 Turbo Cup An astonishing winning machine


    The following season saw Ragnotti's car win the Tour of Corsica. Even so, Renault's absolute priority was its commitment to Formule 1, which meant the R5 Turbo did not take part in the world championship. Nonetheless, a lightweight, independent body was set up to continue the adventure and run national championships for the various subsidiaries. A Racing Customers Department was opened to sell more than 350 racing cars to professional or amateur drivers, offering a choice of five different models. Between 1981 and 1986 the R5 Turbo added to its list of international wins. The drivers who took it to victory were little known at the time but were soon to make names for themselves. They included Carlos Sainz, Didier Auriol, Bruno Saby, Franšois Chatriot and Dany Snobeck.

    From racing to current production

    The assembly line for the Renault 5 Turbo, which provided a link between racing cars and roadgoing models, went into production at the Alpine plant in Dieppe on May 20, 1980. A total of 802 units, available in red or blue, were made that year, 536 the next year and 352 the year after that.

    The European Cup

    On April 5, 1981, the Renault 5 Turbo Cup was launched on the Hockenheim circuit in Germany. The first season covered 12 races on the leading European circuits, starting with Formula 1 Grands Prix and the Le Mans 24-hour race. All these events helped to further establish the fame of the car that won hearts and raised dust all over Europe. They also confirmed that its founding fathers were right to have made a commitment to an exceptional human and technological adventure.

    Here we go, concise and definitive engines from the Alpine-Renault experts

    ....

    hi

    turbo1 and turbo2 were 1397cc engines

    200 turbo2 were built to homologate the maxi 1410cc

    maxi 5 turbo 1527cc

    the rest is ( bricolage).

    Very concise indeed. I found the "bricolage" statement funny because sunday I've been reeding a magazine wich featured the Maxi Turbo that campained at the Spanish national championship by Carlos Sainz. I immediately thought of our conversation so I went to check the specs. And there was some nice "bricolage". the car had 2100cc and...a sequential gearbox!
    That surely sounds sweet...

    Thanks for your investigation.

    That was the same mag I've read. however I find strange that the car has "only" 350bhp after being oversized to up 2000cc. It probably does a little more BHP.

    I think I'm a little late to the conversation, but I'd just like to say that that car is probably the coolest French anything ever.
