The
F430's chassis is heavily based on its predecessor, the 360. Internally, both
cars are referred to as the same model (F131), but for the most intimate, the
car is simply known as the Evo.
The
design of the F430 was developed jointly by the studio Pininfarina and Ferrari.
The style is inspired by old racing cars, especially the model 1961 world
champion Formula 1 with Phil Hill, and also in the modern - in the back, it is
a reduced copy of the Enzo. According to Ferrari, the aerodynamics received
priority over the visual. The body was sculpted in the wind tunnel in order to
obtain a good drag coefficient (Cx), high pressure into the ground (down force)
and sufficient airflow to cool brakes and engine.
Regarding
F360 predecessor, the new V8 grew 20% for transportation, shrank in the
external dimensions and won only four kilograms of mass. Contributed to this
new materials and components of small size (as the dry sump and clutch of
smaller diameter). The intake system has been improved with the use of pipes
and valves dimensions equal to those of Formula 1 engines. Camshafts are
continuously variable intake and exhaust to and driven by a hydraulic high
pressure. The power curve is nearly a straight line (with a slope of 60 degrees
relative to the x axis). And the torque runs parallel to power until it reaches
its peak. The 3500 rpm has 23% power to 80% of torque. The maximum power of 490
horsepower arrives at 8500 rpm and maximum torque of 47.4 lb-ft at 5250 rpm. On
the track, the performance is out of the ordinary. According to Ferrari, the V8
accelerates the 1450 kg of F430, 0-100 km / h in just 4 seconds. And the
maximum speed reaches 315 km / h. With all this performance, the engine is able
to meet the emission limits of European standards (Euro 4) and American (LEV2).
Brakes
The
brakes of the F430 were designed in collaboration with Brembo. The result has
been a new cast-iron alloy for the discs. The new alloy includes molybdenum
which has better heat dissipation performance. Another option Ferrari is
providing is the carbon-ceramic discs. The pottery has a heat resistance much
higher than metals, thus providing not only a good performance to F430 brakes,
but also a longer lifespan. Ferrari says that the brakes do not desgatam even
after 300-350 laps at the Fiorano circuit, a test track.
Manettino
The
wheel of the F430 is a summary of those in the Ferrari Formula 1, piloted by
Felipe Massa and Fernando Alonso. The racetrack riders have different dials
that adjust parameters such as time shifting, differential control and throttle
opening. On the streets, drivers have the option of five programs that govern
the behavior of the car, interfering with the suspension, transmission and
other electronic controls. Outside the slopes, it makes sense to individually
adjust each position of the car, as the torque distribution between the wheels,
for example, each curve.
The
programs developed for the F430 provide different degrees of sportiness, the
taste of the driver. But Ferrari recommends that the selection meets the
conditions of adhesion pathways. In the first, called Ice (ice), the
intervention of electronic systems is complete.
The
exchange rate enters the automatic mode, with soft and exchanges without
stretching the gears, and stability control and traction (CST) works in the
safest way possible. This option should be used when running on snow or ice. In
the second, Aderenza Bassa (low tack), the rates can be used in manual mode,
but the CST still remains cautious. It is ideal for use in wet conditions. The
intermediate mode is the standard car, the Ferrari christened Sport. With it is
the best compromise between stability and performance.
In
relation to the above, the suspension gets a more sporty and CST behavior
becomes more tolerant. It is recommended for dry track. Those seeking a
direction more sports can opt for Race (race). This, according to the factory,
should be used only in closed circuits, where the car can be enjoyed without
major risks.
The
rates reduces the time of shifting by the CST only acts at risk and the
suspension is firmer. In the fifth stage (represented by the acronym CST),
stability is no longer controlled by electronics, only the ABS remains in
place.
The
pilot takes full responsibility for his actions. Even the electronic
differential takes a break. In this mode, goes into operation a program fixed
standard conditions for maximum performance. The rates and suspension remain
configured with the behavior of the previous mode.
