Ferrari 250 GTO
Charisma came not only from its innumerable racing
victories, but from the unique sum of its parts – stunning looks, a highly
competitive chassis and a thoroughbred V12 engine.
The 250 GTO model was the pinnacle of development of
the 250 GT series in competition form, whilst still remaining a road car. It
made its public debut at the annual pre-season Ferrari press conference in
January 1962, and was the only front engine model on display, with its
monoposto and sports racing counterparts all having a mid-engine configuration.
The power unit was essentially a 250 Testa Rossa
specification version of the Colombo single overhead camshaft per bank 3-litre
V12 engine, with bore and stroke of 73 x 58.8 mm, but using dry sump
lubrication, with factory type reference 168 Comp/62. The spark plugs were
outside the vee of the block, and there was a bank of six twin choke Weber 38
DCN carburettors, with a twin coil and rear of engine mounted distributor
ignition system, to produce a claimed 300 bhp.
The engine was coupled to a new 5-speed, all
synchromesh gearbox, with an open gate gear-change tower in the cockpit,
similar to that used on the sports racing models since the mid-fifties, driving
through a propeller shaft to the rigid rear axle, fitted with a Watts linkage.
As befitted its intended competition use, a wide range of rear axle ratios was
available.
On its first outing at Monza in September 1961,
prior to the Italian Grand Prix, the 250 GTO earned the nickname ‘Il Mostro’
(The Monster), due to its rough-hewn and ill fitting prototype body. During
test sessions, Stirling Moss drove the car to record times far better than
those ever achieved by a 250 GT ‘passo corto’. A ‘palace revolution’ followed
later in the year, and Bizzarrini found himself on the outside, with refinement
of the GTO body entrusted to Sergio Scaglietti, who created its definitive
shape.
The 250 GTO was the ultimate expression of the
Ferrari 250 GT car. It was equally at home on the road or track – perhaps the
last dual purpose road/race car produced – and has achieved legendary status
amongst aficionados of the marque. With only a relatively small production run
of thirty-six cars, and with many of the examples produced having a great race
pedigree, it has become one of the icons of Ferrari production history, with a
revered position in collector’s circles.
