Dino (car)

Dino () was a marque best known for mid-engined, rear-drive sports cars produced by Ferrari from 1957 to 1976. The marque came into existence in late 1956 with a front-engined Formula Two racer powered by a brand new '' Dino'' V6 engine. The name Dino was used for some models with engines smaller than 12 cylinders, it was an attempt by the company to offer a relatively low-cost sports car. The Ferrari name remained reserved for its premium V12 and flat-12 models until 1976, when "Dino" was retired in favour of full Ferrari branding.

History

The name Dino honors Ferrari founder Enzo Ferrari's late son, Alfredo "Dino" Ferrari, credited with designing the V6 engine used in the car. Along with engineer Vittorio Jano, Alfredo persuaded his father to produce a line of racing cars in the 1950s with V6 and V8 engines. The ''Dino'' script that adorns the badge and cylinder head covers was based on Alfredo's own signature. The Dino models used Ferrari naming convention of displacement and cylinder count with two digits for the size of the engine in decilitres and the third digit to represent the number of cylinders, i.e. 246 being a 2.4-litre, 6-cylinder and 308 being a 3.0-litre, 8-cylinder.

Single seaters

Dino 156 F2

The first race car to ever bear the Dino marque badge was the 1957 Dino 156 F2 single seater intended for the Formula 2 series. Powered by an all-new, front-mounted, 65° '' Dino'' V6 co-designed by Vittorio Jano and named in memory of Enzo Ferrari's late son, Alfredo "Dino" Ferrari.
The new V6 engine, first built and tested in 1956, had to adhere to 1.5 litre, Formula 2 regulations.

Total capacity was (bore of 70 mm and stroke pf 64.5 mm) and power output was at 9000 rpm with a 10:1 compression ratio. The fuel system consisted of three Weber 38DCN carburettors and used regular fuel. The valvetrain was of a twin overhead camshafts per bank type with two valves per cylinder and single spark plugs.

As per the naming convention, the 1.5-litre, 6-cylinder car was named 156 and made its debut at the Naples Grand Prix in 1957. The chassis was made of steel tubes with independent front suspension, a de Dion rear axle along with Houdaille shock absorbers. Only one example was produced: s/n 0011. Its drivers included Luigi Musso, Maurice Trintignant and Peter Collins.

Luigi Musso managed to score third place at the time of its debut at the Naples GP and Maurice Trintignant won the Coupe de Vitesse. After two second places at the Modena GP (in both heats) by Musso.

The engine was upgraded to 1860 cc in 1957 (later 2195 cc), to 85 x 71 mm at 8500 rpm in 1958 for Formula One specification and renamed Ferrari 246 F1 and in 1959.
In 1960 the engine was updated with a lower V-degree (65º>60º), a shorter stroke: 73 x 58.8 mm, 1476.6 cc and a single overhead camshaft.

This racer gave birth to a whole generation of V6-powered, Ferrari-built cars.

Dino 166 F2

A change in Formula One rules for the 1966 season brought changes to Formula 2 as well. New homologation requirements meant that at least 500 production units of the same engine block were to be produced. Ferrari turned to Fiat to produce a more affordable sports car for this purpose. Fiat produced two models with the ''Dino'' engine in coupé and spider form under the name Fiat Dino. And so for the 1967 European Championship season Ferrari was able to field a new car, the Dino 166 F2 with a rear-mounted, longitudinal 65° '' Dino'' V6 engine. The car made its debut at the Racing Car Show in Turin in February 1967.

Specifications

The new powerplant had of total capacity with a bore of 86 mm and a very short stroke at only 45.8 mm with a Heron type 3 valves head. A single 'split' overhead camshafts per bank actuated the valves per cylinder: two inlet directly by the camshaft and one exhaust through a rocker. In 1968, the cylinder measures changed to 79.5 x 53.5 mm () with an 11:1 compression ratio.
In 1969, the power grew from at 10,000 rpm to at 11,000 rpm. Fuel feed was by Lucas indirect injection and ignition by Magneti Marelli transistorized twin-plugs, later changed to a single ignition.
The chassis was a semi-monocoque with all-independent suspension and disc brakes. Seven cars were built, of which three were later converted for the Tasman race series with engines enlarged to 2.4 litres.

Racing

The cars were raced by Ernesto Brambilla, Chris Amon, Andrea de Adamich and Derek Bell. Their first F2 wins were the 1968 Hockenheim race and later the GP Roma at Vallelunga.

Dino 246 Tasmania

For the 1968 season of Formula One, Ferrari had returned to the V12-engined cars. This created a need to pursue other racing venues for their already existing projects. The Tasman Series for cars up to 2500 cc was just that venue and the Dino 246 Tasmania was just such a car. Converted from the Dino 166 Formula 2 basis with the engine enlarged to 2.4 L to meet the requirements without overstretching the engine.

Specifications

The new displacement of was achieved thanks to of bore and stroke. Internal dimensions were identical to that of the 246 F1-66. At an 11.5:1 compression ratio, power output was a healthy at 8900 rpm. Already standard on 65° '' Dino'' V6 twin overhead camshafts per bank, and a novelty: four valves per cylinder. The same as its predecessor, the chassis was a semi-monocoque with all-independent suspension and disc brakes.

Racing

Only three cars were made and raced with success between 1968 and 1971, mainly in hands of Chris Amon and Graeme Lawrence. The Tasman Series was particularly suited for the Dino Tasmania. Chris Amon won two races in the 1968 Tasman Series and dominated the 1969 edition by scoring four wins in New Zealand and Australian Grands Prix and won the Drivers' Championship. In 1969, Amon was aided by Derek Bell in the other Scuderia Veloce car with enough points for fourth place. For the 1970 Tasman Series the winning car was handed over to Graeme Lawrence who won only one race but with four other podium finishes still won the championship.

Sports racing cars

Dino 196 S

The first sports racing car under Dino marque was 2.0 L '' Dino'' V6-engined Dino 196 S. The first example, s/n 0740 made in 1958, had a 65° DOHC configuration, as found in its Formula Two predecessor and is sometimes referred to as 206 S. The other, s/n 0776 from 1959, had its engine redesigned as a 60° SOHC version. A possible third car was immediately upgraded to 3.0 L specification and never raced it its two-litre form. All early Dino sports cars actually had Ferrari badges on the front.

Specifications

Both cars' engines had of total capacity from of bore and stroke. Both used the same carburettor setup with three 42DCN Webers, resulting in the same power output. The differing factors were the rpm range: 7200 for the DOHC, 7800 for the SOHC engine and a twin spark plug arrangement for the DOHC-variant. Both cars were created on a tubular chassis with independent front suspension and live rear axle. The first car received Scaglietti coachwork, but was soon rebodied by Fantuzzi, who also bodied the second car. Their style was reminiscent of a Ferrari 250 TR and was often referred to as a 'smaller Testa Rossa'.

Racing

The first Dino 196 S made its debut at the Goodwood Sussex Trophy driven to second place by Peter Collins. After being converted to SOHC form, it scored silver for the 1959 Le Mans Test and a single victory at Coppa Sant Ambroeus. The last race for this car was the 1959 Pontedecimo-Giovi hillclimb in which another second place was achieved before the car was dismantled at the factory. The other Dino had a much longer career. In 1959, driven by Ricardo Rodriguez it finished fourth and second in a couple of races at the Governor's Trophy, Nassau. The following year the car was entered in the Targa Florio and finished seventh overall.

Replicas

Numerous replicas had been made of this model. Approximately twelve examples based on a tubular chassis with handcrafted aluminium bodywork in Fantuzzi spider style. Cars were created either by anonymous builders or by Vincenzo Marciano, an Italian private constructor. Power came from 2.4 L four-cam V6 Fiat Dino road car engine mated to a 5-speed ZF transmission.

Dino 296 S

The second Dino-badged sports racing model was the 1958 Dino 296 S. Only a single example, s/n 0746, was made with a near 3-litre V6 engine. It had a 65° configuration with twin overhead camshafts per bank and two spark plugs per cylinder. Total capacity was thanks to internal measurements of 85 x 87 mm. With three Weber 45DCN carburettors, power was an impressive at 7600 rpm.

A tubular steel chassis with independent front suspension, de Dion rear axle and drum brakes was clothed with a spider Fantuzzi bodywork as seen on its siblings from the same period. The fuel tank had 177 litres capacity.

Its first outing was in England at Silverstone Circuit in May 1958, where Mike Hawthorn scored third place. After just a single race the car was converted into an experimental 250 Testa Rossa model and raced in June, the same year, at the 1000km Nürburgring, where Wolfgang von Trips and Olivier Gendebien finished third overall. The model was further raced by Ricardo Rodriguez in the Bahamas and United States.

Dino 246 S

For the 1960 season, Ferrari presented a new derivative of their V6-engined sports racing car, the Dino 246 S. Its engine was closely related to that found in the Ferrari 246 F1 but designed as a 60°, chain-driven, single overhead camshaft per bank variant. Only two examples were ever created, s/n 0778 and 0784, the latter known as the 'high tail' spider.

Specifications

Internal measurements of 85 x 71 mm and resulting capacity of 2.4 L () were identical to the Formula One sibling. At a 9.8:1 compression ratio with three Weber 42DCN carburettors, rated power output was at 7500 rpm. The engine used a single spark plug per cylinder served by a single coil. This would be the last Dino sports racing car with a front-mounted engine.

The chassis was constructed out of steel tubes with independent front suspension and a live axle at the rear. The wheelbase was . Bodies were designed and executed by Fantuzzi, both in the style previously seen on the Dino cars, but s/n 0784 was rebodied as a 'high tail' spider before 1961 12 Hours of Sebring race. Brakes were of a disc type all-round.

Racing

The Dino 246 S debuted in January 1960 at the 1000km Buenos Aires but failed to finish due to ignition problems. Its first success came when both cars were entered in the 1960 Targa Florio, finishing second and fourth overall and first and second in the 'Sports 3.0' class. Phil Hill and Wolfgang von Trips drove the car that finished second. Ludovico Scarfiotti, Willy Mairesse and Giulio Cabianca were in the other car. In 1960, s/n 0778 was recreated at the factory after a pit stop fire damage at the 1000km Nürburgring. Both cars continued their later careers in the United States. The 'high tail' spider driven by Jim Hall and George Constantine scored sixth place and won its 'Sports 2.5' class at the 1961 12 Hours of Sebring.

Sports prototypes

Ferrari SP series

The Ferrari Dino SP was a series of Italian sports prototype racing cars produced by Ferrari from 1961 through 1962. This first series of Dino-engined sports prototypes included the 246 SP, 196 SP, 286 SP, 248 SP, and 268 SP; distinguished from each other by use of V6 and V8 engines in different displacements. All shared a similar body and chassis with a rear mid-engine layout, a first for a Ferrari sports car. Major racing accolades include the 1962 European Hill Climb Championship, two overall Targa Florio victories, in 1961 and 1962, and " 1962 Coupe des Sports" title.

At first the SP-series used Vittorio Jano-designed, V6 '' Dino'' engines in both SOHC 60° and DOHC 65° forms. Later, Ferrari introduced a new SOHC 90° V8 engine designed by Carlo Chiti. All used dry sump lubrication and were mated to a 5-speed manual transmission.

After 1963, these Ferrari SP models were no longer used by Scuderia Ferrari and passed into the ownership of private individuals or independent racing teams. They were succeeded by the Dino 166 P in 1965.

Dino 166 P

The 1965 Dino 166 P was created by Ferrari to compete in endurance racing with categories up to 1600 cc or even 2000 cc. One chassis that raced, s/n 0834, sported brand new all-aluminium berlinetta bodywork inspired by the Ferrari P-series of cars but with smaller dimensions. It was designed and built by Piero Drogo's Carrozzeria Sports Cars in Modena. This new style would be carried over to the rest of the Dino race car family. This was the first Ferrari-made sports prototype to bear the rectangular 'Dino' badge on the front of the car and also the first to be bodied with a closed body. A second car, s/n 0842, never raced and was converted into the works prototype of the Dino 206 S.

Specifications

The engine, mounted in the rear, displaced 1.6 L () from of bore and stroke. The compression ratio was 11.5:1 and with three Weber 40DCN/2 carburettors and twin spark plugs per cylinder, resulting power was at 9000 rpm. From this moment on, every Dino race and road car would have a 65°, twin overhead camshafts per bank with two valves per cylinder engine. As a race engine it also used dry sump lubrication.

A tubular steel chassis now received full independent suspension, front and rear. The wheelbase was long. Disc brakes all-round were standard at the time. The whole car weighed only dry.

Racing

After a failed attempt at the 1000km Monza in May 1965, the following month the 166 P was entered into the GP Roma on the Vallelunga track. Giancarlo Baghetti won it outright, two laps ahead of a Porsche. The same month Lorenzo Bandini with Nino Vaccarella scored a respectable fourth place overall and second in 'Prototype 2.0' class at the 1000km Nürburgring, ahead of cars with much bigger engine capacity. Just after failing to finish the 1965 24 Hours of Le Mans race due to engine problems, the 166 P was developed into the Dino 206 SP with completely open bodywork and a bigger 2.0 L engine.

Dino 206 SP

The Dino sports prototype model that followed the 166 P was the Dino 206 SP. The first example was an exact conversion from is predecessor, still with the same s/n 0834, but with new barchetta body and a bigger 2.0 L engine. Designed specifically for the European hillclimb events, the car is also referred to simply as the Dino 206 P. A second car, s/n 0840, was the basis for the concept car, Dino Berlinetta Speciale by Pininfarina.

Specifications

The biggest change was the engine enlargement to 2.0 L () so that car could make full use of the 2000 cc category limit. The engine was redesigned by Ferrari engineer Franco Rocchi for Formula Two use. This displacement would be carried over not only to the 206 S, the succeeding model, but also to the Fiat and Dino road cars as well. The larger displacement was due to bigger bore, now at , and stroke was the same as before. Power rose to at 9000 rpm, with all of the remaining specifications the same apart for all-new Lucas fuel injection.

All of the chassis and suspension configuration was carried over without change. The 206 SP received new low-slung barchetta bodywork that was a whole lower, now at . Only a small, wrap-around windscreen and a single roll bar protruded above the bodywork. Due to this mass reduction the overall dry weight of the car measured up to , that is more than a saving. All this was with twisty hillclimb competition in mind. Later the car was rebodied in style with the 206 S and received similar roll bar-roof treatment.

Racing

The new car debuted at its first hillclimb in Trento-Bondone in 1965, winning it outright in the hands of Ludovico Scarfiotti, despite being described as "an absurdly dramatic climb". He also won three more races in a row: the Cesana-Sestriere hillclimb, the Freiburg-Schauinsland hillclimb and Ollon-Villars. At the Gaisberg hilllclimb in August 1965 Scarfiotti finished fifth but still won the European Hill Climb Championship. This was his second championship for Ferrari, the first he won back in 1962 in a Ferrari 196 SP. In 1967 the 206 SP was lent to Scuderia Nettuno that entered the car in the Targa Florio, placing fourth overall and third in the 'Prototype 2.0' class, driven by Vittorio Venturi and Jonathan Williams. Venturi then placed third in yet another hillclimb event at Monte Erice. Leandro "Cinno" Terra entered the 206 SP for the 1969 Targa Florio, but finished in a distant 25th place. Its last period race was the Coppa Collina, where it finished in second place.

Dino 206 S

The last of the Dino prototype sports car models was produced in 1966–1967. 18 examples were made with Group 4 category homologation in mind. Still powered by 2.0 L () engine based on the 206 SP powerplant. Some received experimental 3-valve heads and Lucas fuel injection.

Concept cars

Ferrari built and presented numerous design concepts and prototypes to overcame styling and engineering challenges derived from a new engine layout of a road-car. As many as six different Dino prototypes were built between 1965-1967. The new and revolutionary design would spawn whole generations of Dino and Ferrari mid-engine road cars.

Dino Berlinetta Speciale

The first Dino-badged concept car was presented by Ferrari and Pininfarina in 1965. It was a mid-engined, two-seater called Dino Berlinetta Speciale. The work started in March 1965. The car was designed by Aldo Brovarone who created the conceptual plans that would in the future form a basic characteristics of the production Dino cars. The project was managed by Leonardo Fioravanti, and its directors included Sergio Pininfarina
