It was never intended that the Bertone
Jaguar Pirana would make it to production, it being manufactured exclusively as a concept for display at the 1967
Earls Court Motor Show.
Then again, it was not simply a hollow shell incapable of being driven. Indeed the Bertone
Pirana was a fully operational concept, based on the chassis of a 4.2 litre E-Type Jaguar
The idea for the car came about amoung a group of motoring journalists who, in March of that year, decided to experiment with the development of a car that would represent the attainable, unlike the offerings from Lamborghini
, Aston Martin
and Iso, their prices ensuring they were the play-things of only the rich and famous.
John Anstey came up with the idea, stipulating that the car should be built from components already in production and available to the public, and that all the latest aids to safety, comfort and performance should be built into it.
By the third week in April the basic design had crystallized, Sir William Lyons
agreeing to sell the Telegraph a 2-plus-2 E-Type Chassis. Then, after a record minimum of letters (two each way), Nuccia Bertone
agreed to design and build the coachwork, promising to complete the job in time for the London (18th to 28th October) and Turin (1st to 12th November) motor shows.
The result was the Bertone
Pirana, a fastback two-seater with abbreviated Doktor Kamm tail and an overall length of just over 15 feet (making it slightly shorter than the E-Type 2-plus-2, which was 15 feet 4.3 inches long). To extend the effective track wide based rims and tyres
(Dunlop cross-ply racing) were used, the cars overall width being 5 feet 6 inches (as compared to the E-Types 5 ft. 5.3 in.).
Being a prototype, the Pirana was heavier than the E-Type, which resulted in a small performance loss when compared with the donor car. That said, there were plenty of other companies prepared to assist with the cars development. Triplex supplied special Sundym glass which featured a thick vinyl interlayer which increased flexibility and resistance to penetration, with both the windscreen and rear window (which was hinged at the top to give access to the luggage space) being heated by wires laid in the interlayer.
Joseph Lucas, with offices in Turin, kept a close watch on their side of the project, which included paired 5 3/4" diameter headlamps at each end of the grille - the main beam being supplied by the inner lamps of each pair, which used quartz-iodine bulbs; the outer, sealed beam lamps being used for dipping.
Smith's Motor Accessory Division played a big part in the luxury side of the original concept, their assistant chief engineer for special products Brian Bishop making many journeys to Turin during the construction of the car. The result was the development of a special heating and air-conditioning system that used a refrigerator which cooled and de-humidified all air - whether it is needed for cooling or heating. It also featured one of the original climate control systems, using only two controls for the selection of temperature and blower speed. Using the principle that warm air rises, and cool comes down, heated air travelled forward along ducts let into the door sills from the heater unit behind the seats, while cool air was distributed throughout the car via a perforated distributor mounted to the roof.
A radiomobile set was linked to Smith's latest tape-recorder and player - the first such unit to use cassettes. Forward thinking safety items included seat-belt reminder lamps and audible warnings, along with speed limit warnings. Inside the Bertone
was functional, the E-Type steering
wheel being carried over and giving a clue as to the origins of the car. The seats were upholstered in top-grade Connolly Anela hide
, and special Britax seatbelts were fitted which used webbing to match the upholstery.
Amazingly the Pirana was finished in time, a true tribute to the people concerned with its development. Much of the design work was carried out behind closed doors, by only Nuccio Bertone
and his chief stylist Marcello Gandini. They found time to develop a clay model which was modified many times before they were happy with the result. Then came full size and to-scale drawings, followed by a full size mock-up (done largely in wood) but using clay for the critical surface areas.
Then came the conversion to steel and alloy panels. While many were responsible for the cars development, special mention should be made of the main players, Bob Berry (then Jaguar executive director in charge of group publicity), Enzo Prearo (Bertone's commercial manager), Brian Bishop (Smith's assistant chief engineer in charge of special products), John Anstey (editor of The Daily Telegraph Magazine), and of course Nuccia Bertone
and Marcell Gandini, Bertone's chief stylist.
