Alfa Romeo
Alfa 8C Competizione, world premiere
The definitive version of the gorgeous exclusive Alfa 8C Competizione,
Gran Turismo car that is to be produced in a limited edition makes its
debut in Paris. The car, designed by Alfa Romeo, is directly derived
from the concept car that aroused such admiration at the 2003 Frankfurt
Motor Show and has benefited from the best technical and industrial
know-how that the Alfa-Maserati Sports Centre can offer. The cooperative
venture between both manufacturers was conducted with a view to ensuring
integration between the Alfa Romeo design departments and the Maserati
production departments.
The 8C Competizione is inspired by Alfa Romeo's glorious past,
projecting its brand values of technology and emotion into the future.
The historical allusions begin with the evocative name, recalling the
great sporting tradition of Alfa Romeo. The 8C code was used to identify
cars (racing and on-road) of the Thirties and Forties equipped with the
revolutionary eight cylinder engine produced by the famous designer
Vittorio Jano. The term 'Competizione' is intended as a homage to the
'6C 2500 Competizione', a sports coupé driven in 1950 by the duo Fangio
and Zanardi in the famous Mille Miglia race.
The name, '8C Competizione' is not an arbitrary invention but a
distinctive mark of Alfa Romeo's own sporting history. A veritable
legend that has arisen out of the innumerable victories won on circuits
throughout the world through the skill of men and their passion for
racing, engine research and advanced technology and a reawakened taste
for new challenges.
This link with the values of Alfa Romeo's history adds extra
poignancy to the term 'Competizione'; when projected into the future it
represents the sense of constant dynamism that distinguishes a brand
engaged in a quest for excellence, increased competitiveness and
technological innovation. This is the explanation behind the role of the
new car, which is not a point of arrival but a point of departure
designed to reaffirm Alfa Romeo's unique place in the world: its ability
to match a thrilling shape to driving satisfaction.
Styling and aerodynamics: tradition and innovation
The attractive shape created by the Alfa Romeo Style Centre makes
this car with its two bucket seats unique in the Gran Turismo scenario.
The designers have worked hard to ensure that the aerodynamic and
performance demands have not altered the car's original concept. The
style maintains an incredibly clean shape, uncluttered by any element
interfering with the overall harmony.
The solutions introduced on the Alfa 8C to achieve the highest levels
of aerodynamic efficiency are not limited to the shape. Air wraps around
the car and follows its natural course, unhindered by corners and
unevenness. All the pillar and glass surfaces and profiles together with
the door mirror shape and position have been optimised by mathematical
modelling and also by wind tunnel tests and tests on actual models. Much
attention has been devoted to the creation of a ground effect that has
allowed a negative Cz (lift coefficient) to help increase stability at
high speed, as on racing cars.
The compact dimensions concentrate the aggression of a car designed
to ensure maximum driving efficiency.
The car surfaces are highly sculpted and skilfully moulded. In
detail, the body is given extra dynamism by the horizontal furrow cut
into the side above the front wheelarch. The big wheels and powerful
musculature of the rear wings emphasise the model's personality and
strength without detracting from the lines that flow smoothly, almost as
though to underscore the formal good looks of the individual exterior
details: the drop-shaped headlight embedded, gem-like, in the front
wing, the led tail-lights that are a blend of technology and
rationalism, the spare door handle. The front end still displays the
distinctive Alfa Romeo traits, with a new interpretation of the
'whiskers' and shield.
The innovative shape heralds the details and proportions of future
Alfa Romeo cars but is also redolent with past thrills and historical
allusions: the 33 Coupé Stradale, the Giulia TZ and many other great
names of motoring history. The Alfa Romeo style centre also developed
new colours to emphasise the shape of the 8C Competizione that match the
car's sinuous shape while also suggesting modernity and a hint of
technology.
8 cylinder 4.7 engine: Italian 'belcanto'
The engine is the beating heart of any Alfa Romeo. In this case it
takes the form of a brand new 90° V 8 cylinder unit with a cylinder
capacity of 4691 cc that was designed with one aim in mind: to ensure
extraordinary performance while still offering a smooth drive and being
usable in all circumstances, from the track to city traffic.
The top engine performance figures may be summarised as a maximum
power output of 450 bhp at 7000 rpm, a peak torque of 470 Nm at 4750 rpm
and a top speed of 7500 rpm.
The layout of internal fluid movements and the cylinder head cooling
system is designed to achieve high duct permeability and effective
intake load cooling to maximise volumetric efficiency and engine
performance.
Harmonisation of the intake and exhaust geometry together with the
introduction of continuous variable valve timing on the intake camshafts
and optimisation of the combustion chamber and engine calibration means
that 80% of torque is available from 2000 rpm.
In sporty driving conditions over mixed routes, the power unit offers
impressively short response times due to the high permeability of the
intake duct and the low inertia of the flywheel-twin plate clutch
system.
A crankshaft with counterweights at 90°, fully balanced through
careful selection of connecting rods and pistons, ensures the engine
runs with low vibration levels.
The engine block and base assembly is in aluminium with 5 main
bearings to ensure the structure is very rigid with little loss due to
friction. The cylinder heads are also in aluminium alloy.
All the ducts (water, oil, secondary air) are cast directly into the
engine to produce a system with great rigidity, low dimensions and
guarantees of safe installation, i.e. great reliability.
Casting accessory systems into the main engine casting and the use of
very rigid, thick-walled components ensures that little noise radiates
from the engine and the components are very reliable.
Longitudinal engine packaging has also received particular attention,
as evidenced by the introduction of a single chain timing system that
guarantees exceptional lifetime dependability.
Special attention has also been devoted to the acoustic definition
and tuning of the intake and exhaust in the quest for a sound timbre
that enhances the car's character and makes it unmistakable. The result
is a full, distinctive sound, emphasised by the permeable intake system
and an exhaust system with electronically controlled valves that enhance
the car's sound without infringing any type-approval or environmental
constraints.
Transmission, robotised gearbox and self-locking differential
The engineers used a layout familiar from other Alfa Romeo cars on
the 8C Competizione: the transaxle architecture with gearbox at the rear
that is an acknowledged asset of Alfa Romeo cars. This layout allows
outstanding dynamic performance while also offering the active safety
for which Alfa Romeo cars are fabled.
The engine-gearbox unit is designed in accordance with a transaxle
configuration that ensures the weight distribution is very effective for
vehicle handling. Due to the small axial engine size and the integration
with frame components from the drawing board, the entire power unit can
be housed well back to ensure the required sporty configuration.
The 6-speed gearbox with computerised speed selection by means of
levers behind the steering wheel is designed to ensure ultra-slick gear
shifts and may be used in Manual-Normal; Manual-Sport; Automatic-Normal;
Automatic-Sport and Ice modes. The self-locking differential allows
acceleration and stability to be managed with extraordinary efficiency
in all situations.
Suspension, wheels and braking system
In the very best Alfa Romeo tradition, the engineering is directly
derived from the race track. The suspension on the new model is no
exception, with a double wishbone layout, forged aluminium axle carrier
and arms and extra strut for toe-in control.
The braking system offers perforated, ventilated discs with aluminium
brake callipers to ensure prompt, effective braking even with heavy use.
To ensure the car stays glued to the road, it is fitted with 20" tyres
specially developed to ensure outstanding performance: 245/35 at the
front and 285/35 at the rear, fitted on perforated rims in fluid moulded
aluminium to ensure lightness and maximum brake ventilation efficiency.
To ensure the car is entertaining and safe in any driving condition,
the 8C Competizione comes with the latest Alfa Romeo VDC, an advanced
stability and traction control system to ensure the driver feels at one
with his car.
Rigid, light structure
A rigid, light structure is the rule when configuring a good high
performance car. This is also the guiding principle behind the 8C
Competizione. In detail, the compact frame is in steel to achieve the
greatest torsional rigidity to ensure an accurate, safe drive at all
times while the body is in carbon fibre. This choice was motivated by
the need to minimise weights while also optimising the car's centre of
gravity for better agility and handling on demanding routes.
Interiors: personality and technology
The car's distinctive look comes from extensive use of composite
materials on the facia and interior panels. This is a technical choice
but also reinforces the car's spirit and emphasises its personality. The
same thinking lies behind the adoption of anatomical seats made out of
carbon fibre that can be adjusted and customised on the basis of the
driver's physical characteristics (a facility previously reserved for
racing cars).
Everything is designed and produced to ensure the greatest
user-friendliness for the driver and whoever is lucky enough to share
the thrill: relaxed driving position, intuitive instruments that are
always visible, robotised gear levers secured to the steering column and
easy to reach without removing your hands from the sporty steering
wheel.
The carefully-crafted and detailed finish naturally allows the car to
be customised to the driver's taste and a choice of different interior
environments is available.
The absolute satisfaction of a sporty drive
To see it is to love it: wide tyres, low-slung ride and styling of
poised aggression. To die for, in fact. Hear the engine and weep: a
full, convincing throaty roar. Now all that remains is to sit behind the
wheel, engage first gear and you are off to try out your Alfa 8C
Competizione. You are left with one doubt: how will you drive a sports
model whose bonnet conceals a 4700 cc eight cylinder engine hat
unleashes 450 bhp of power and 470 Nm of torque when you touch the
accelerator. The unexpected answer is: with great ease - even more
easily, simply and instinctively than your normal car in fact. Provided
you allow yourself the time and satisfaction (because this is about
pleasure, after all) of getting used to the more direct controls and
prompter responses: the sort you could only expect from a true sports
car on mixed routes or - even more so - on the track where speed and
transverse acceleration are much more controllable.
The new Alfa 8C Competizione is self-avowedly an Alfa in its
uncompromising sense of control and driving satisfaction. Driving
comfort and dynamic behaviour have always been specific features of Alfa
Romeo cars: on this car, they amount to a real strength.
Alfa 8C Competizione: a legendary name for a unique car
Since the very beginning, the Alfa Romeo spirit has been driven by a
constant quest for technical perfection, achieving performances that are
better and better. This is all about the engine: the beating heart of
every Alfa Romeo car. Racetracks throughout the world have provided the
perfect backdrops for truly unique technical and technological progress,
with Alfa Romeo always occupying the highest position on the winners'
podium.
The key to Alfa Romeo's engineering prominence was the 8 cylinder
engine developed during the first half of the Twenties by a young
engineer named Vittorio Jano. His original brief was to revise the 6
cylinder engine to meet the needs of standard production model buyers
and also to stand up to the competition offered by rival manufacturers
in races.
The first 8C was tested in 1923, with the P1, already fitted with a
compressor and twin spark ignition, and then the P2. Its debut could not
have gone better: in 1925 the Alfa Romeo P2 won first place in the first
World Championship. The positive effects of these innovations were not
restricted to the engines of production cars but the glory of this
result was included in the 'Alfa Romeo - Milan' badge in the form of the
laurel crown that was to adorn all Alfa Romeo cars from that day on.
At the beginning of the Thirties, the powerfully reliable 8 cylinder
engines - now in light alloy - purred like cats under the bonnets of
stylish cabriolets and coupes (whose bodies were built by the Milanese
Zagato and Castagna) and roared like lions in the dust of races such as
the Mille Miglia and Targa Florio, that added to the impressive list of
victories. The thrilling wins achieved by the Alfa Romeo 8C in 1931,
1932, 1933 and 1934 at Le Mans deserve special attention (the car was
later called the 'Le Mans' in the wake of these great successes).
The 8 cylinder engine achieved its technical peak in the Alfa Romeo
Tipo B engine, known as the 'P3' to highlight its technological
relationship with the P2. Campari, Nuvolari, Caracciola, Borzacchini,
Marinoni, Guidotti and Fagioli were just some of the champions who owed
their successes to the 1932 and 1934 versions of the 8C engine in the
face of the challenges posed by the most prestigious circuits in the
world.
The continual progress and consistent technical research culminated
in the 8C 2900, the unbeaten star of racing from the Mille Miglia to the
Le Mans 24 hour. The car, an extremely stylish 8C with its body built by
Touring especially for Le Mans, was driven peerlessly by its driver
Biondetti. This engine was exceptionally long-lived: an 8C 2900 B driven
by Biondetti and Romano won the Mille Miglia again in 1947, proving yet
again and over an exceptionally arduous route, that Alfa Romeo engines
were possessed of truly extraordinary power and reliability.
World War II only halted the victorious progress of the 158 for a
short period. The legendary 'Alfetta', a distillate of superlative
automotive engineering qualities, first saw the light in 1946. In the
words of Juan Manuel Fangio, driving this 8 cylinder car was like
'holding the bow of a Stradivarius in your hands'. First the 158 and
later the 159 brought Alfa Romeo laurels in the first two modern Formula
1 world championships, with Nino Farina in 1950 and with Fangio in 1951.
After the Formula 1 victories, Alfa Romeo decided to withdraw from
racing to devote itself to the demands put on it by its latest arrival,
the 1900 and later the Giulietta range. 1967 saw the return of the
powerful 8 cylinder engine fitted to racing 33 models and responsible
for the attractive, resolute shape of the road version of the 33. This
car also enjoyed a very encouraging racing debut, with Teodoro Zeccoli
taking top position on the winners' podium after the uphill race in
Fleron, Belgium, in a 33/2 Sport Prototype.
Other 33 cars met with considerable success on tracks and circuits
throughout the world during the Seventies. This technical perfection was
transferred to standard production cars such as the Montreal, a car of
great prestige and performance, whose 8 Cylinder engine was derived from
the unit fitted to the 33 models used for racing. In 1977, the 8
cylinder engine was fitted to a limited series of the Alfetta GTV,
produced by Autodelta which thus continued the sporting tradition
applied to engine production.
Now the legendary heart of that engine comes back to beat under the
bonnet of the new Alfa 8C Competizione. |
