The 499P Modificata represents a brand new type of challenge for Ferrari: a track-only mannequin developed instantly from a racing automobile moderately than a manufacturing mannequin, however with out the restrictions imposed by technical rules.
Design
The design of the 499P Modificata was outlined in collaboration with the Ferrari Styling Centre directed by Flavio Manzoni. The automobile flaunts its technical and aerodynamic qualities by way of easy, sinuous varieties in an express expression of its Ferrari DNA.
The flat higher floor of the flanks is sculpted to harmoniously give type to the facet pods and wheelarches. The latter are characterised by massive openings, with the intention of lowering strain contained in the wheel housings. The headlights lend the entrance finish character and an expressive high quality, their design intently evoking the styling cues that make the automobile immediately recognisable as a Ferrari.
A light-weight carbon-fibre pores and skin wraps across the powertrain, leaving wheels and suspension utterly uncovered.
The tail is characterised by a horizontal double wing, with the higher profile fastidiously designed to provide the required downforce.
The decrease wing additionally homes a lightweight bar that lends the design of the rear finish a decisive, minimalist character. A a number of air consumption for the V6 engine and for cooling the battery and gearbox dominates the automobile’s roof.
Variations with the 499P
Whereas the 499P Modificata is predicated on the 499P, not having to adjust to FIA WEC sporting and technical parameters has allowed Ferrari’s engineering workforce to introduce quite a lot of important modifications that improve driving thrills and make the automobile’s efficiency extra accessible.
The foremost technical modifications embrace the electrical axle and four-wheel drive that may be activated even at low speeds; the “Push to Go” operate, which affords drivers the choice of an additional 120 kW of energy; particular tyres developed by Pirelli, and a whole recalibration of the suspension set-up, digital controllers and engine mappings.
The 499P Modificata retains the cockpit, with its single-seater format, and ergonomics of the 499P, offering purchasers with precisely the identical driving expertise because the crews who drove the racing automobiles #50 and #51 that took the win, Hyperpole and quickest lap within the race on the 24 Hours of Le Mans.
Its apparent derivation from the 499P makes the 499P Modificata the highest-performance closed-wheel automobile that Ferrari has ever proposed for non-competitive use on the observe.
The automobiles might be fielded within the new Sport Prototipi Clienti programme that, from 2024, will run alongside the prevailing F1 Clienti programme. This permits 499P Modificata house owners to take part in quite a lot of occasions on worldwide tracks yearly, with Ferrari taking good care of logistics, track-side help and upkeep.
Powertrain
The 499P Modificata’s hybrid powertrain combines a mid-rear mounted inner combustion V6 with an electrical motor on the entrance axle. The system can ship a most energy output of 640 kW (870 cv), unhampered as it’s by FIA-ACO rules. The ICE shares the structure of the facility unit fitted to the 296 GT3 however has been utterly revised by Ferrari engineers to develop devoted options and decrease the overall weight.
A very distinctive attribute of the 499P Modificata’s V6 engine is the truth that it’s load-bearing, so it performs a useful structural operate, in comparison with the GT racers the place the engine is mounted on a sub-chassis.
The powertrain is supplied with a 200 kW (272 cv) electrical motor with a differential and an Power Restoration System (ERS) which recharges the battery throughout deceleration and braking. The 800 volt battery pack was developed utilizing the corporate’s Method 1 expertise. The ability unit is coupled to a seven-speed sequential gearbox.
Structure
Sporting an all carbon-fibre monocoque chassis, the 499P Modificata options state-of-the-art options akin to push-rod suspension, and a classy braking system incorporating brake-by-wire that enables the electrical entrance axle to recuperate power throughout braking.
The mechanical set-up (centrally-mounted shock absorbers and is derived, anti-roll bars) has been specifically designed to maximise driving thrills and make sure that the automobile behaves predictably in all circumstances. The engine and driveability maps have been fine-tuned in keeping with the identical philosophy; particular traction management logic was developed to facilitate torque administration on the grip restrict, and a devoted start-assist logic was additionally launched.
With respect to the 499P, the 499P Modificata makes use of particular Pirelli tyres that have been developed for predictable dealing with and to maximise suggestions in non-competitive driving, making them fast to heat up and selling constant grip ranges for a number of laps over sheer peak efficiency.
Car Dynamics
Not having to adjust to the FIA WEC rules allowed the engineers to introduce new options on the 499P Modificata. The primary regards activating the entrance axle at low pace (the 499P was restricted to speeds above 190 km/h) enabling the motive force to learn from four-wheel drive. This resolution affords benefits by way of efficiency and driveability, making it doable to take advantage of the extra grip supplied by the entrance wheels, and to optimise the distribution of torque between the axles. The result’s a automobile that feels much more responsive and exact popping out of turns, making it simpler for drivers to search out the perfect racing traces, and galvanizing confidence in driving to the restrict in a automobile that’s able to extraordinary efficiency.
One other vital modification made doable by the 499P Modificata’s freedom from particular regulatory constraints is the introduction of the “Push to Go” system. This lets the motive force profit from 120 kW (163 cv) of energy obtainable for a restricted time period through the lap along with the nominal 520 kW (707 cv) output, thus attaining a complete most energy of 640 kW (870 cv). The logic is conceptually much like that launched in Method 1 in 2009 with the KERS system.
The driving force can activate the system utilizing a button on the again of the steering wheel; the additional energy is barely obtainable when the accelerator is pushed to full throttle and for a length of not more than 7 seconds per activation. The utmost variety of activations per lap is dependent upon the observe kind and battery power stability: the system routinely deactivates beneath a sure cost threshold after which reactivates when power restoration has recharged the battery to an applicable degree.
The 499P Modificata is supplied with particular tyres – 310/710-18 entrance and 340/710-18 rear – developed by Pirelli beginning with digital simulations. Based mostly on FIA rules, the slick design encompasses a devoted construction and tread compound derived from F1 know-how. Improvement was geared toward emphasising the automobile’s driveability and maximising dealing with suggestions for non-professional drivers, optimising heat up instances and lowering efficiency degradation throughout lengthy runs. The rain tyre additionally boasts a brand new tread sample and compound and was developed to make sure the perfect grip in semi-wet and full-wet circumstances.
