The Ferrari 458 Speciale joins the Ferrari range alongside
the 458 Italia and 458 Spider and, like all special-series Ferraris, is aimed
at a specific kind of owner, in this case those looking for an even more
focused sports car that offers extreme driving emotions.
Whether on the road or on the track, drivers will feel
immediately at one with the 458 Speciale thanks to the speed with which it
responds to every input and the consequently natural control that it offers,
even in extreme manoeuvres. This finely-tuned handling balance enables the car
to reach the highest performance levels of any Ferrari V8.

Interior
The cockpit features a distinctly racing-inspired
atmosphere, with simplicity the order of the day. Lightweight exclusive
technical materials, such as Alcantara and carbon-fibre, are used extensively
but meld seamlessly with the superb craftsmanship and sophistication typical of
all Ferrari interiors, courtesy of exclusive details, contrasting
hand-stitching, aluminium triangular-pattern tread plates and sills with a
pewter grey finish, and particularly fluidly sculpted door panels.
The glove compartment on the dash has been replaced with
convenient odds and ends pockets on the tunnel and doors. This has
significantly streamlined the volumes under the dash adding practical padding
at knee level.
Onboard ergonomics are absolutely functional with all
controls clustered around the driver and on the steering wheel. This concept
has been further enhanced by the use of the iconic bridge, a carbon-fibre wing
that extends over the central tunnel section, putting the F1 gearbox controls
at an ideal angle to the driver. There is also a comfortable leg rest cushion
on the driver's side of the tunnel.
Design
Aerodynamic requirements guided the work of the Ferrari
Styling Centre which collaborated on the project with Pininfarina to sculpt
forms that are more performance-oriented than ever, balancing aerodynamic
requirements while staying true to Ferrari's aesthetic philosophy.
Most of the bodywork panels have been redesigned without
modifying either the passenger cell or the signature design features of the 458
Italia. The thickness of the glass used has been reduced to cut weight, while
the rear windscreen is now a Lexan© panel.
Gear-shift strategy
The F1 dual-clutch transmission now features a new control
logic that delivers an even keener sense of urgency during gear shifts. The car
feels much sportier as it shifts up through the gears, with response time to
commands more prompt than ever, thereby guaranteeing 40 per cent faster
longitudinal acceleration with engine revs adapting 20 per cent more rapidly.
Conversely with the Fast-Down Shift strategy, when down-shifting, the transient
time required for engine revs to match the gear ratio is 44 per cent faster.
Soundtrack
Like the rest of the car, the Ferrari 458 Speciale's
soundtrack is both seductive and uncompromising, thanks to unprecedented
intensity inside the cabin as well as outside. The position of the tailpipes
lends the V8 the full-bodied low frequency soundtrack typical of Ferrari's
sportiest engines while the configuration of the silencers is designed to
guarantee maximum intensity and exceptional clarity. The immense power and
full-bodied nature of the sound inside the cabin were achieved by redesigning
the inlet tract.
Suspension
Thanks to being very flat through corners, the 458 Speciale
is extremely efficient and satisfying in faster, sharper, more challenging
changes of direction. This is due partly to its Frequency-Shaped SCM-E (Frs
SCM-E) dampers which have twin solenoids, new CPU and new software that
modifies the magnetic field every millisecond. The result is a much faster
response and more precise body control.
Tyres and wheels
Part and parcel of the Speciale's development included
Michelin Pilot Sport Cup2 tyres which were specifically honed for it in an
intensive collaboration programme involving lengthy track tests and simulator
sessions.
Specially made for the Ferrari 458 Speciale, they feature a
compound obtained using specific additives to boost performance over a single
lap in the dry as well as improving performance consistency over multiple laps.
They also deliver 6 per cent more grip, which also translates into better grip
even in the wet.
Braking system
To cope with the demands of the car's increased performance,
all of the components in the Brembo braking system have been evolved from the
solutions introduced on the LaFerrari. The 458 Speciale sports Extreme Design
calipers, new generation HT2 discs with a higher percentage of silicon, and
smaller front pads made from HY hybrid material for improved heat dissipation
which is also boosted by special channels in the bodywork and is crucial in
extreme driving situations. The result is shorter stopping distances (100 - 0
km/h in 31 m) without any compromises in weight, and more consistent
performance under severe use.
Side Slip Angle Control (SSC)
The Ferrari 458 Speciale sees the introduction of Side Slip
Angle Control (SSC) for more effortless car control on the limit, thereby
greatly enhancing driver enjoyment.
Thanks to sophisticated new software, which computes lateral
acceleration, yaw angle, steering wheel angle and speed, SSC carries out
instantaneous analysis of the car's side slip angle, comparing it with
reference data, thereby allowing smooth, controllable oversteer, and optimising
both torque management (via F1-Trac traction control) and differential torque
distribution between the two driven wheels (via the E-Diff electronic
differential) for maximum vehicle response times.
Dynamics
The Ferrari 458 Speciale's dynamic behaviour guarantees
maximum driving emotions in all situations, allowing drivers to match and
improve their own limits with ease and delivering an intense driving experience
even at lower speeds.
Nimble and responsive, the car is at its best over really
twisty routes with demanding switchbacks and camber changes. New technical
features have not only improved the 458 Speciale's lap time over single laps,
but also the repeatability of that performance on subsequent laps without
needing to be a professional driver, offering unprecedented levels of driving
pleasure.
Powertrain
The 458 Speciale's mid-rear-mounted 4497 cc GDI engine is
the most powerful naturally aspirated Ferrari 8-cylinder ever developed,
punching out 605 cv at 9000 rpm and maximum torque of 540 Nm at 6000 rpm, while
its record 135 cv/l specific power output is also the highest ever achieved by
a naturally-aspirated road-going engine.
F1 technology transfer to the Ferrari 458 Speciale was of
fundamental importance to its development, including the production processes.
The engine is produced in the factory's in-house foundry using the same
machinery and processes as employed by the F1 team for complex components with
the extreme structural and dimensional characteristics needed for a
naturally-aspirated engine capable of hitting 9000 rpm.
Aerodynamics
One of the car's main characteristics is new
Ferrari-patented mobile aerodynamic solutions at the front and the rear of the
car which ensure that different aerodynamic configurations can be adopted in
cornering, where maximum downforce is essential, and on straights where,
instead, drag must be reduced to a minimum.
