Engine
The F430 is powered by a new 90° V8 featuring Ferrari's traditionally
uncompromising design approach with a flat-plane crank (180° between throws).
This is an all-new unit that does not share any components with the 360 Modena's
engine. The improvement in terms of performance, weight and reduction of overall
dimensions is the result of applying Ferrari's wealth of F1 experience to its
road cars. Despite a 20% increase in engine displacement (from 3586 cc to 4308
cc), engine weight has grown minimally by just 4 kg, while performance is
considerably improved across the board. Torque increases by 25% (343 lb-ft at
5250 rpm, 80% of which is already available at 3500 rpm) and power by 23% (490
bhp at 8500 rpm). The engine is extremely compact with a cylinder spacing of
just 104 mm. Similarly, Ferrari's engineers integrated the sump and main
bearings in a single casting which, along with a smaller diameter twin-plate
clutch and flywheel, has reduced the engine height between the bottom of the oil
sump and the crankshaft to just 130 mm (from 145 mm on the 360 Modena power
unit).
E-Diff Electronic Differential
One of the technical features that sets the F430 apart is the E-Diff or
electronic differential. This solution has been used for years in F1 single-seaters
and has been continuously developed and refined, effectively transferring
massive torque levels to the track under extremely high cornering g-forces. The
E-Diff is now standard equipment on the F430 - the first time that a production
car has been equipped with such a sophisticated system for high-performance
roadholding. On the track, the E-Diff guarantees maximum grip out of bends,
eliminating wheel spin. On the road it is a formidable technological refinement
that improves roadholding. This system is available both on the F1-paddle shift
version as well as on the manual gearbox model and consists of three main
subsystems:
- a high-pressure hydraulic system, shared with the F1 gearbox (if present);
- a control system consisting of valve, sensors and electronic control unit;
- a mechanical unit housed in the left side of the gearbox.
Transmission and F1 Gearbox
The F430 features a new cast-aluminum transmission casing that houses the
gearbox in unit with the electronic differential and bevel type final drive, as
well as the engine oil tank. The 6-speed gearbox incorporates multicone
synchronizers, while both the 6th gear and the final drive have been lengthened
to make the most of the greater power and torque of the new engine. The F430 is
available with either the classic Ferrari open-gate manual gearbox or with the
F1 paddle shift that Ferrari has continuously developed and refined over recent
years for its road-going berlinettas. Thanks to that ongoing development,
Ferrari's F1 gearbox for the F430 is state of the art, introducing a number of
important modifications: thanks to inputs from the engineers on the Gestione
Sportiva racing side, the F1 gearbox management incorporates a new control
strategy which further perfects gearchange speed and smoothness under hard use.
Changing gear takes just 150 milliseconds, as measured by the 'hole' in
acceleration during the change (intended as the overall time from declutching,
changing gear to releasing the clutch).
Interior
The F430's interior has been re-designed for improved driver ergonomics. The
instruments are housed in a new binnacle, and this design together with the
layout of the dashboard underlines the care that has gone into grouping all the
major controls in front of the driver within easy reach. In the driver's direct
line of sight are the rev counter, which features new graphics with a choice of
either a red or yellow background and a new metal surround, the digital readout
of the gear ratio selected (F1 version) and a multi-function display. The same
uncompromising approach to driver control was the inspiration behind mounting
the starter button and manettino on the steering wheel. The wheel itself is new
with the upper rim flattened to improve visibility in the straight ahead
position, and the horn pushes are integrated into the inner rim where they can
be easily actioned. The interior reflects the advanced technology and materials
employed in the car's construction, and can be personalized with carbon-fiber or
aluminum inserts. The cockpit is noticeably bigger and the already excellent
passenger comfort is subsequently increased thanks to a slimmer central tunnel
which houses the gear lever turret on the manual version and the F1 console on
the paddle-shift version. There is plenty of space behind the rear seats, with a
new electrically operated compartment for oddments storage and catch netting to
the rear fire wall. The seats have been redesigned for greater lateral
containment and the standard electric seats can be substituted by more sporting
items with four-point harnesses to order (depending on markets).
