Design
Alfa Romeo 4C Concept
is a two-seater: it is just under 4 metres long, 200 cm wide, 118 cm high and
with a wheelbase of less than 2.4 metres, rear-wheel drive coupé with
technology and materials derived from the Alfa Romeo 8C Competizione, with 1750
turbo petrol engine with direct injection, the "Alfa TCT" twin dry clutch transmission, the Alfa DNA
dynamic control selector.

The interior of the Alfa Romeo 4C is the result
of an in-depth study of anthropometric and ergonomic parameters that
established a relationship between the sports layout of the car and features
that form a 'continuity' with the design of the body. It is a design concept in
which the various elements - dashboard, instruments and seats - follow specific
driver and passenger usability and comfort criteria.
Definition of the interior took on particular importance when
configuring the carbon fibre 'monocoque' cell.
This veritable 'monolithic core'
led to a rational organization of the main construction elements in keeping
with the principle of integrating parts and optimising weights. Initially
focused on arranging controls and instruments so they are turned toward the
driver, this approach actually simplified construction in terms of assembly
processes and separation into subassemblies when industrializing the project.
The climate control system ducts are integrated with the
entire dashboard block, which contains a supporting 'technical spider'
structure inside the mould. Consisting of a thermoformed shell like those found
on limited edition supercars, the dashboard is designed to make using functions
simple and reaches its zenith in the concept of extreme driver-orientation,
thanks to digital instruments and gear shift controls located on the
appropriately shaped steering wheel.
The cockpit, which powerfully suggests the world of
motorcycle racing and race cars, brings together all information necessary to
drive and control the car. All readings are visible on the instrument panel,
comprising an original digital display, containing all the control functions
for the Alfa Romeo supercar.
Driving pleasure is the result of carefully
balanced design. Rear wheel drive and a centrally mounted engine: the
architecture of the Alfa Romeo 4C is typical of competition cars in which
perfect weight distribution is the primary objective.
The Alfa Romeo 4C has rear wheel drive to make full use of
the dynamic advantages afforded by this configuration. Rear wheel drive gives
better grip under acceleration, when engine power throws weight towards the
rear of the car. Rear wheel drive also lets you enter curves at higher speeds,
delivering a far more intense driving experience.
Having defined the 4C's architecture, Alfa Romeo
engineers started to search for the most suitable materials for this solution.
Aluminium, steel, SMC and carbon fibre were chosen for their ability to combine
lightness and efficiency. In this way a total dry weight of only 895 kg was
achieved. This record makes the Alfa Romeo 4C one of the lightest cars in the
world.
The secret of the lightness and dynamic behaviour of the Alfa
Romeo 4C lies in the 10% of carbon fibre used, which represents as much as 25%
on the entire volume of the 4C. Today carbon fibre is the material that
guarantees the best efficiency between weight and stiffness.
This is why it was chosen for the monocoque with a structural function that constitutes the central self-supporting cell of the chassis. It is a solution adopted by most advanced supercars. It combines savings in weight with excellent performance. In fact, the monocoque weighs only 65 kg.

The Alfa Romeo 4C achieves maximum aerodynamic efficiency
levels, guaranteeing a negative Cz which, as in racing cars, contributes
towards achieving increased stability at higher speeds thanks to the negative
lift.
SMC (Sheet Moulding Compound) is used for the
bodywork. It is a low-density, high-resistance composite which offers a 20%
weight reduction compared to the traditional steel shell. The Alfa Romeo 4C is
the first standard production vehicle with such a high percentage of
low-density SMC: at just 1.5 g/cm3 it is significantly lighter than steel (~7.8
g/cm3) and aluminium (~2.7 g/cm3), as well as being more malleable.
This
feature granted that freedom in terms of style and design necessary to create a
real Alfa Romeo recognizable at first glance. It is also a stable material
which, in contrast to aluminium, does not deform in minor collisions, and is
extremely resistant to chemical and atmospheric agents. It also disperses sound
efficiently, increasing acoustic comfort.
Low-density SMC also ensures significant functional
integration between parts, leading to a reduction in components, operations and
assembly time, thus lowering production costs.
PUR-RIM (injected polyurethane) was also chosen for the
bumpers and mudguards for the reasons mentioned. It is a lightweight material
(-20% compared to steel) suitable for creating even highly complex design
elements like a 4C mud guard.
Engine
The new '4 cylinder' 1750 Turbo Petrol with direct injection
at 200 bar that achieves performance of absolute excellence is making its début
on the Alfa Romeo 4C. Torque and specific power set new records for this size
of engine at over 200 Nm/l and 137 HP/l, respectively, while maximum power of
240 HP (176 kW) is reached at 6000 rpm. The maximum torque of 350 Nm ensures
its extraordinary elasticity and sportiness since it is maintained constant
between 2100 and 4000 rpm, but 80% of the torque is already available at just
1800 rpm.
Fitted out like this, the compact supercar registers
exceptional results both during pick-up and when accelerating. The Alfa Romeo
4C goes from 0 to 100 km/h in just 4.5 seconds and develops a top speed of over
250 km/h. Driving pleasure is magnified by the full, rich sound of the exhaust,
where the low frequencies and classic roar have been emphasized.
This
impressive level of performance has been achieved with minimum impact on the
environment. Thanks to multiple injection control and advanced anti-friction
and energy loss reduction systems, the emissions of the Alfa Romeo 4C fall well
within the strict limits of Euro 6.
The Alfa Romeo 4C's advanced 'scavenging'
technology maximizes torque at low engine speeds and delivers more power in
response to driver input. The control unit determines valve overlap times and
angles with great precision to create a through-flow of air from the inlet
manifold to the exhaust manifold. By improving the scavenging of the combustion
chamber, this direct flow increases combustion efficiency and turbine speed and
reduces turbo-lag.
To complement the 'scavenging' technology, the engine is also
equipped with a new generation turbocharger and a pulse converter exhaust
manifold that exploits pressure waves to boost torque at low engine speeds. The
manifold and the turbine are made from microcast steel and designed to operate
at very high temperatures (over 1000°) - a pre-requisite to low fuel
consumption on medium-high speed motorway journeys. The wastegate valve is
another helpful device
