Dino 246 GT, an extraordinary and unmissable evolution of the 206 version



In 1969, only a year after the release of the Dino 206 GT, the Maranello company perfected the six-cylinder Ferrari.

The reasons for this decision were due: an increasingly fierce competition, such as the Porsche 911 Carrera, and above all regulatory issues relating to Formula 2; in fact, the sporting regulations drawn up by the FIA ​​require the use of an engine derived from road production and built in at least 500 units in order to participate in competitions.


The engine grows in displacement, passing from 2000 cm³ of the 206 GT, to 2400 cm³, thanks to the increase in the measures relating to the bore and stroke, and by modifying the cast iron engine block, guaranteed greater overall robustness and less sensitivity to Vibrations, thus defining an increase in power, which goes from 180 to 190 horsepower.

The power supply remains unchanged with three Weber 40 DCN F/7 double-barrel carburettors.

The larger dimensions of the engine entail technical aesthetic changes, since the 246 GT remains apparently identical to the previous version, but in fact the length increases, which increases by 90 millimeters, and the wheelbase, now greater than 58 millimeters, is also lengthened. favoring interior habitability and accessibility to the engine compartment during maintenance, both pain points of the 206 GT.



The development inevitably also affects the mass of the car, which reaches 1.080 kg when empty, also because the bodywork, again entrusted to Scaglietti, is made of sheet steel, with the exception of the bonnets and doors, which remain in alloy light.


Despite this, performance is not affected, and indeed res of first-rate: 235 km / h of top speed, from zero to one hundred in 7.2 seconds, and 27.5 seconds from zero to one kilometer.


The driving experience is enhanced by the sound of the engine and the five-speed gearbox, distinguished by the classic selector grille; an inspiration deriving from racing Ferraris.


Agility and very direct steering certify the Dino 246 GT as a real Ferrari, should there be any doubts. The marvelous line, designed by Aldo Brovarone of Pininfarina, remains almost unchanged compared to the Dino 206 GT, however, small aesthetic variations, which do not escape the eye of the most passionate, characterize the three versions of the Dino 246 GT called L, M, IS.


The L series, built from 1969 to 1970, has some aesthetic details that will represent the fortune of the 2000 version, including the Cromodora rim fixed with the central wing nut, similar to racing cars, the front corner bumpers that end inside the socket air on the nose, the trunk lid release button, the license plate lights incorporated in the rear bumper, and the headrest mounted on the rear bulkhead.

The frame numbers of the Tipo 607 L follow a numbering equal to the difference from the rest of the road range of the Prancing Horse.



At the end of 1970 the M series made its début (Type 607 M chassis from number #01118 to #02130), increasingly marking the gap from the 206 GT: the rim, also Cromodora, loses the central wing in favor of the five-bolt fixing, the headrests integrated into the seats and the opening of the luggage compartment is now done via a button inside the passenger compartment.

The available accessories increase, while from the mechanical and chassis point of view the braking system is improved, and the rear track increases by 30 millimeters.



The last evolution of the species, the Tipo 607 E (chassis #02132 to #08158), went into production in 1971, and remained there until 1974. For the first time the two-seater berlinetta was joined by an open version, the GTS , equipped with a removable hardtop type license plate.


Further changes such as new carburetors, the rest position of the wiper, the new Campagnolo rims and the door opening control, complete the swan song of one of the most successful berlinettas from the Maranello company.



A total of 2.487 Dino 246 GTs are built, of which 488 are right-hand drive, while the GTS are 1.274, of which 235 right-hand drive, for a total of 3.761 units, a truly remarkable number for Ferrari production in recent years.


Despite the large numbers, the Dino remains one of the most sought after and coveted Ferraris by enthusiasts and collectors, as evidenced by the great interest that this car comes out every time it is sold at the best auctions in the world.
