Introduction

With the Ferrari 430 Scuderia, Ferrari has confirmed its vocation as a manufacturer of road cars that combine the most sophisticated technology - tried and tested in Formula 1 - with class-leading performance.

The Ferrari 430 Scuderia boasts 20 more bhp than the F430 (503 bhp compared to 483 bhp at 8500 rpm) while shaving 100 kg (220 lb) off the dry weight. That is sufficient to guarantee the kind of performance that makes the Ferrari 430 Scuderia a milestone in Ferrari's lengthy line of V8 berlinettas. The Ferrari 430 Scuderia is, in fact, virtually on a par with the Enzo Ferrari supercar, with 0-62 mph acceleration in under 3.6 seconds, a top speed of 320 km/h (198 mph) and, most significantly, a Fiorano lap time of 1'25" - the same as the 2003 Enzo.

Extensive aerodynamic development has brought an increase in downforce without penalising the car's Cd figure of 0.343, while the adoption of massive vented carbon-ceramic discs as standard has ensured even more powerful, responsive and consistent braking.

Michael Schumacher was actively involved in the development of the 430 Scuderia, putting to good use the years of F1 experience that have made him a legend, honing the integration of E-Diff and F1 Trac settings for maximum grip in acceleration out of corners - up 40 per cent on the track and 20 per cent on the road compared to a traditional traction and stability control system.

Design

The concept of the 430 Scuderia was based on enhanced performance and dynamics so the basic design of the F430 was honed to improve the aerodynamics without increasing drag. Ferrari’s engineers worked to increase downforce, adopting a more pronounced profile of the lower bumper’s leading edge, a new central lower flap, more angular front air intakes in the bumper and wider-meshed grilles. At the rear, the gain in downforce over the front axle is balanced by a more prominent nolder on the leading edge of the tail, and a completely re-designed rear diffuser.

In this configuration, the Ferrari 430 Scuderia’s bodywork generates 75 kg (165 lbs) of downforce at 150 km/h (93 mph) and over 300 kg (660 lbs) at maximum speed.

The Ferrari 430 Scuderia sits 15 mm (0.7 in) lower than the F430 and features new sills with larger air intakes to the engine compartment. Other changes involve new 10-spoke alloy wheels, carbon-fibre wing mirrors and a new rear bumper with high exhaust tailpipes as seen on the Ferrari Challenge racing version of the F430.�

Technical Features
The Ferrari 430 Scuderia’s engine is a development of the F430’s 4308 cc 90 degree�V8. Power has been increased from 490 to 510 hp, while torque has also been improved across the rev range, with an increase of up to 10 per cent at low and medium revs, and up to 4 per cent from 6000 to 8500 rpm. 80 per cent of torque is already on tap at 3000 rpm.

The latest F1 Superfast 2 software is employed for the 430 Scuderia’s electro-hydraulic F1 gearbox. It is thus the road-going Ferrari with the fastest change time ever, with the entire gearchange operation – which in Ferrari parlance means the time power is removed then re-applied to the driven wheels, not just the time to change gears – taking just 60 milliseconds. That’s close to F1 times of around 40 ms.

The Ferrari 430 Scuderia is also the first Ferrari to employ both the innovative electronic differential (E-diff) and F1 Trac. The result of this combination on the track, with the ‘Race’ manettino setting selected, is a 40 per cent increase in acceleration out of corners compared to a traditional traction and stability control system. On the road, and with the ‘Sport’ setting selected, this equates to a 20 per cent increase in acceleration out of corners, with virtually indiscernible intervention of the control systems even in extreme situations.

To match the Ferrari 430 Scuderia’s superior performance, the engineers equipped the car with the latest carbon-ceramic brakes discs, with massive 398 x 36 mm (15.6 x 1.4 in) front discs with 6-pot forged aluminium callipers, and 350 x 34 mm (13.7 x 1.3 in) rear discs with 4-pot callipers. The Scuderia also features the latest ESP 8.0 CPU which reduces calculation and reaction times by about 15 per cent.

Interior
Contributing to the Ferrari 430 Scuderia’s class-leading power-to-weight ratio is a typically sporting and Spartan interior. Weight has been saved by using specific materials, from the grippy, standard technical fabric trim for the seats, to the extensive use of carbon-fibre for the main interior fittings, such as the inner door panels, central tunnel and the seats themselves. The latter – known as Super Racing seats - are a development of those used in the Enzo, with a carbon-fibre shell and manual adjustments, and come in three sizes.

Additional weight has been saved by reducing the sound-proofing material (albeit without reducing acoustic comfort) and by removing the carpeting – the floor is now in aluminium, with parts of the underlying aluminium chassis visible.

The instrument display has new graphics and the steering-wheel mounted paddles come in carbon-fibre as standard.

Along with the other models in the range, the Ferrari 430 Scuderia benefits from a wide range of personalisation options from the Carrozzeria Scaglietti programme, with special focus on the Racing and Track area.

intrduction
The Ferrari Challenge Stradale had the precise aim of giving drivers the performance and feel of a true racing car for road use. This aim meant that Ferrari technicians gave exclusive preference to Ferrari Challenge and 360 GT racing-type solutions for all aspects of the car and every single performance parameter, the combination of which gives this car its highly individual character. The starting point was aerodynamics, where the aim was to obtain increased downforce, and followed by all the vehicle-specific features (transmission, set-up and braking, in particular the introduction of carbon-ceramic brakes as standard). And finally, that determining factor for all racing cars ' achieving the lowest possible weight.
Design
The starting point for the Ferrari Challenge Stradale was the Ferrari Challenge version of the exceptional 360 Modena. The 360 Modena, with its longitudinal engine and front mounted radiators, is a model of sports car efficiency, performance, and luxury. Ferrari worked with Pininfarina to modify this well balanced, benchmark platform through aerodynamics and weight reduction to create the world's most desirable V8 sports racing coupe.

The goal of aerodynamic modifications was to increase the downforce, allowing for higher cornering speeds. The already slippery 360 Modena body was fitted with a revised underbody design and extremely subtle aerodynamic aids, helping the Ferrari Challenge Stradale stick to the road without contributing to top speed-sapping drag.

Reducing weight and controlling its distribution is a primary goal of every race car designer. The all-aluminium 360 Modena was a very light car with high structural rigidity. By deleting options unnecessary to performance and dynamic response, and judicious use of carbon-fibre, the Ferrari Challenge Stradale enjoyed a drastic weight advantage over all its forebears.

The Ferrari Challenge Stradale built on aerodynamic concepts employed on the 360 Modena and took advantage of a stiffer, lower racing set-up, adopting solutions that led to a gain of 50% in downforce compared with the 360 Modena. The results are significant: at 125mph the load increase is over 88lbs for a gain equal to the effect of a wing with a surface area of almost 3 square feet. Despite such a significant increase in downforce, the car has a drag coefficient of 0.335, the same as the 360 Modena.

At the front, the Stradale's bumper extends below the air intakes to increase downforce at the front without disrupting airflow towards the rear.

The underbody of the Stradale was modified with the introduction of longitudinal fences on the rear diffuser to balance the load, while the rear nolder was reshaped to provide greater efficiency appropriate to its function.

The Stradale's sills were redesigned to streamline the rear more completely, improving the car's efficiency and balance. More aerodynamic carbon-fibre mirrors and Challenge-style 19" wheels have been adopted to further improve airflow at the sides.

Weight reduction was a primary goal of the Ferrari Challenge Stradale project, achieving a reduction of 243 lbs compared to the 360 Modena.

As with the 360 Modena, the Ferrari Challenge Stradale's body components and space frame are made from a combination of aluminium castings, extrusions and sheets. It is the first Ferrari V8 car to employ, as standard, carbon-fibre technology on structural parts such as door panels, racing seat shells and air filter-box covers, and for both interior and exterior trim.

Titanium, already used for the connecting rods, was also adopted for Stradale suspension parts including wheel bolts and coil springs. Titanium has provided a significant reduction in unsprung weight.

Luxury features are not elemental to the Stradale's nature, and many impose a weight penalty on production and racing cars. All 360 Modena features that did not directly relate to improved dynamic performance or that would be out of place on the track were eliminated, allowing for a further reduction in weight without impacting safety engineering or driving enjoyment.

The Ferrari Challenge Stradale boasts the following areas of weight saving: over 24lbs (4%) to the engine and gearbox, 11lbs (3%) to unsprung weight and 207lbs (12%) to the body. Reducing a car's weight reduces its inertia. Along with increased peak power from the Ferrari V8 engine, this translates in acceleration from 0 to 60 mph in 4.1 seconds and the quarter mile in 12.2 seconds.
Technical Features
The Ferrari Challenge Stradale was equipped with the existing 360 Modena 90' V8 engine longitudinally mounted behind the cabin in unit with the transmission and differential. Peak power output was raised to 425 hp at 8,500 rpm, an exceptional specific power of 118.5 hp per litre, the most powerful naturally-aspirated V8 ever built by Ferrari. The extremely high peak torque remains unchanged at 275lb-ft at 4,750 rpm.

Modifications to the engine include: optimisation of the compression ratio and fluid dynamics through changes to the heads and pistons, polished intake and exhaust ports and manifolds; specific intake timing; use of a new low-load loss airflow meter; reduced exhaust back pressure; reduced friction cylinder liners, and repositioned valve springs.

The Ferrari Challenge Stradale was equipped exclusively with Ferrari's six-speed F1-type electro-hydraulic transmission. In keeping with the character and purpose of the car, the Ferrari Challenge Stradale's F1 transmission has no automatic mode. "Sport" and "Race" modes are provided for manual changes, the latter capable of consistently accurate 150 millisecond gear-shifts. The choice of these settings engages corresponding integrated car-control logic affecting damper set-up and traction control (ASR) to optimize handling. In "Race" mode with ASR disengaged the driver can engage the "launch control", carry-over of race technology from F1 for high-performance standing starts on good surfaces.

Developed from the superb handling package of the 360 Modena, the Ferrari Challenge Stradale significantly enhances the same basic architecture.

The titanium front and rear springs are 20% stiffer than on the 360 Modena and a larger diameter rear anti-roll bar has been fitted. Roll and squat have been reduced allowing the Stradale faster, better controlled reaction to steering and directional changes while giving the driver more direct feedback. Shock absorber settings have been revised and the car's centre of gravity has been lowered by 0.6".

The Ferrari Challenge Stradale benefits from carbon ceramic discs: the result of highly advanced studies conducted by Ferrari and the manufacturer of this system, Brembo. The 15" x 1.3" front discs and 13.8" x 1.3" rear discs feature 6- and 4-pot callipers respectively. The carbon-ceramic system installed on the Ferrari Challenge Stradale, together with the aluminum brake carriers, produce astounding performance and braking distances, with the added benefit of a 16% weight reduction over conventional brake discs of the same size. The result is 15% better deceleration rates than the 360 Modena.

Specially designed Pirelli P Zero Corsa super-low profile tyres help hold the Stradale to the road surface. Front tyres measure 225/35 while rears measure 285/35, and all are mounted on 19" Challenge-style wheels secured by titanium bolts. This choice of tyre reflects longstanding co-operation between Pirelli and Ferrari, as demonstrated by the Ferrari Challenge-Pirelli Trophy and the FIA GT Championship. Comprehensive testing led to the development of the tyre compound and tread pattern to maximize controlled transfer of power to the road, and a very high lateral acceleration of 1.3g while maintaining superb balance and thermal conditions.

Interior

The Ferrari Challenge Stradale's cockpit contains only essential items. Everything kept from the 360 Modena's interior has been rationalized and reinterpreted in the context of competition. Where appropriate, interior aluminium parts have been replaced by carbon-fibre to reduce weight.

As on Ferrari Formula 1 cars, the steering wheel has a flattened crown to improve the driver's line of sight. Behind the wheel are fitted F1 gear-change paddles, the right one lengthened to facilitate upshifts when accelerating out of corners.

The tachometer is located at the centre of the carbon-fibre instrument panel, redesigned with yellow graphics and red indicators that ensure optimum contrast and legibility for the driver's main point of reference within the car.

Carbon-fibre racing seats upholstered with a high-grip fabric are a centrepiece of the cabin. Carpeting and floor mats are not found in the Challenge Stradale.
