25.07.2007 DIATTO GT OTTOVŲ PROJECT GETS THE GREEN LIGHT

The Diatto GT Ottovų project created by Zagato is set to be realised in a limited-production run of just 99 units, signifying the rebirth of one of the world's oldest automotive brand names.

With a tradition born 170 years ago, Diatto is considered one of the oldest brands in the world amongst the forerunning manufacturers of the automobile industry. Thanks to historic bonds with Ettore Bugatti, Alfieri Maserati and Tazio Nuvolari the name Diatto evokes the pioneering spirit of motor sport. The Diatto story starts in Italy, in 1835 when the artisan Guglielmo Diatto opened a workshop to construct coaches. In the middle of the 1800s his sons, Giovanni and Battista, expanded manufacture to include trams and railway carriages, constructing the luxurious Trans Europe Express. Diatto's automotive history then kicked off when engineers Vittorio and Pietro Diatto, grandsons of the founder Guglielmo, the third generation of the wealthy dynasty of distinguished industrialists, founded the Diatto automobile workshop in Torino. The workshop (6,000 m2) was on a 25,000 m2 plot and employed 500 workers. Fiat at the time employed 776 people. Diatto first produced luxury sports cars with 4.6 and 8 cylinder, supercharged engines, and it had built more than 8,500 cars by the time automotive assembly finally ceased between the wars. Spare part production continued up until 1955 at which point the name vanished and Diatto joined the many long forgotten brands from the pioneering days of Italian car industry.

The Diatto name remained just a memory until the occasion of the Geneva Motor Show in the this spring when it was announced - out of the blue - that two enthusiasts of the historic marque had hatched ambitious plans to re-launch the name, and the first step of this saw Zagato present on its stand a vivid metallic green Ottovų project prototype. Soon after the prototype appeared at the Villa d'Este Concorso d'Eleganza. Now it has been revealed that the car will go into limited production to be dubbed as the Diatto GT Ottovų. Just 99 examples will be built, and thumping power is guaranteed courtesy of a 4.6-litre V8 developed by Roush and Cosworth, which offers a hefty 530 bhp, but which can also be upgraded to 650 bhp. Diatto will start putting in place a specialised dealer network and the Diatto GT Ottovų will be sold in the United States as well as Europe.

Diatto GT Ottovų

The Diatto GT Ottovų is the stylistic re-interpretation of the 1920s Diatto Grand Prix car, featuring the characteristic fused tail. Diatto wanted to create a sporting and elegant car following a neoclassic design, with settled lines and soft volumes, anticipating the future trends in terms of style. These desires have been skilfully interpreted by the Zagato Atelier. The car has been created, characterised by a determined and aristocratic personality, harmoniously combined without ostentation, exuding glamour and prestige and moulded with the noblest of materials: aluminium.

The Diatto GT Ottovų chassis is at the same time the bearing structure and the platform of the vehicle, as were the Diatto chassis of old. It contains all the components necessary for moving and driving the vehicle. Even without the body-work, the chassis is independent, having the same “motoring” characteristics as the complete vehicle. While for other cars the chassis is an essential element for increasing the rigidity of the chassis and consequently safety, the Diatto chassis independently and superbly meets all safety criteria.

The interior of the Diatto GT Ottovų, sober, smart and comfortable, has been inspired by a rationalistic design, which adheres to the ideals of functional character and comfort.

Entirely realised in forged steel, it has a flexing rigidity which is very high, equal to 26KN/m/Degree. It has been planned for competitions and for tolerating tension forces and mechanical stresses created by engines which have over twice the power. The Diatto chassis is the result of a steady, projectual and technological evolution of three previous Italian super cars.

Respecting its own sporting tradition, the Diatto GT Ottovų combines harmony, comfort and sports driving. In order to harmonise comfort and sports driving, it is equipped with two independent double triangle suspensions with extremely long arms, allowing the wheels major excursion without variations in trim. This characteristic can be particularly appreciated during fast curves and rough surfaces, where the steering column doesn’t require continuous corrections, even at high speeds. This particular arrangement grants an easy and confidential capacity of drive, especially during long and tortuous distances

The Diatto GT Ottovų utilises the classic layout of its historic predecessors, that of front-mounted engine and rear-wheel-drive. However the design has been evolved to improve traction (distribution of weight) and driving pleasure. The distribution of weight has been optimised by positioning the engine behind the axis of the front wheels, giving the engine a more central positioning. For easy driving the occupant has been positioned on the plane that holds the barycentre of the car, thereby the vehicle “rotates” around the occupant, minimising the centrifugal forces due to the rotation of the car and increasing the sense of safety and fluidity of drive.

The interior, sober, smart and comfortable, has been inspired by a rationalistic design, which adheres to the ideals of functional character and comfort. The cockpit praises the particular care dedicated to the perception of its general proportions and is harmonised by details. The valuable leather upholstery prospers from Italian craftsmen working to a high level of detail. Inside you can breathe an atmosphere of personalized grace, in perfect harmony with the exterior dimensions.

The Diatto GT Ottovų has a powerful, 8-cylinder, 32 valve, 4600 cc engine, with volumetric compressor and double cam, which produces 530 hp and can be increased up to 650 hp. The engine is prepared by Cosworth and Roush, Ford’s officially accredited sports elaborators will be specially adapted to best satisfy the demand for Diatto’s European and American customers. All the functional parameters of the engine are governed by an electronic exchange with exclusive Diatto mapping.

The engine is coupled to a 6-speed gearbox, with manual or automatic option. The braking system is supplied by Brembo, designed and modulated for speeds of around 300 km/h. The homologation for pollution levels will meet the Euro 5 standard. The Diatto GT Ottovų body has been entirely realised in aluminium and boasts a total weight of only 1450 kg. With a power-to-weight ratio of 2.75kg/hp, the car is at the top of its segment and still has the advantage of having four seats. Acceleration from 0 to 100 km/h, is a shade under 4 seconds. Stopping distance from 100 km/h to 0, is in around 33 meters.
