Ferrari presenterar F12tdf

Ännu mer redo för racerbanan

Spionfotografer har under en ganska lång tid sett mystiska versioner av Ferrari F12 smyga omkring och det har sedan dess snackats om att en Speciale-version därför skulle vara runt hörnet. Nu presenteras den, men den heter inte F12 Speciale utan F12tdf där tdf är en förkortning av Tour de France. Cykeltävlingen kanske ni tänker? Nej, detta är en hyllning till långloppsracingen Ferrari dominerade i på 50- och 60-talet. Den 9 november äger den officiella avtäckningen rum men bilder och fakta kring bilen får vi ta del av redan i dag.

Bilen byggs i en begränsad upplaga om 799 stycken exemplar och det köparna får är en F12 som är ännu mer anpassad för att köras på banan. Effekten ur den 6.2 liter stora V12:an har skruvats upp från 740 till 780 hästar och vridet har ökats med 15 Nm till 705. 0-100 km/h ska gå på snabba 2.9 sekunder, 0-200 på bara 7.9 sekunder medan toppfarten anges till över 340 km/h. På Ferraris egna testbana, Fiorano, klockar bilen in på 1:21. Tjänstevikten anges till 1 520 kilo vilket innebär att ingenjörerna har lyckats trolla bort 110 kilo jämfört med en vanlig F12. Bromsoken hämtas från LaFerrari vilket gör att den nya stoppsträckan från 100 km/h blir 30.5 meter, från 200 km/h 121 meter. Nytt är även bakhjulsstyrning, som gör bilen ännu bättre på att ta kurvor.

Utseendemässigt skiljer sig bilen genom ett helt nytt kjolpaket, ett par nya luftintag och en överlag mycket mer aggressiv design. Den är bredare, lägre, argare och så mycket uppkäftigare än tidigare.

F12tdf – NEW LIMITED EDITION SPECIAL SERIES DELIVERS

TRACK-LEVEL PERFORMANCE ON THE ROAD

OFFICIAL DEBUT ANNOUNCED FOR THE FINALI MONDIALI

AT MUGELLO ON NOVEMBER 8

Maranello, 13 October 2015 – Ferrari reveals the F12tdf which pays homage to the Tour

de France, the legendary endurance road race that Ferrari dominated in the 1950s and

‘60s, particularly with the 1956 250 GT Berlinetta which won four consecutive editions.

It was a race that rewarded cars that combined maximum performance with the

driveability and ease of use that enabled the competitors to race for hundreds of

kilometres a day over fast, tortuous roads and on circuits. The F12tdf is the ultimate

expression of the concept of an extreme road car that is equally at home on the track,

and just 799 will be built.

The F12tdf is a concentration of technical innovations which involve all those areas

central to Ferrari’s DNA: engine, aerodynamics and vehicle dynamics. As a result, in

terms of acceleration, roadholding and agility, the new berlinetta is second to none.

The F12tdf’s performance is assured by the 780 cv, naturally-aspirated V12 derived

directly from the F12berlinetta’s multi-award-winning engine. The car’s exhilarating

dynamic behaviour, specifically its lateral acceleration in corners, is due to an 8%

increase in the ratio of the front tyres compared to the rear ones. The car’s natural

tendency to oversteer as a result of the change in tyre sizes is compensated for by the

innovative rear-wheel steering system – known as the Virtual Short Wheelbase, which

is integrated with the other vehicle dynamic control systems – that guarantees the

steering wheel response times and turn-in of a competition car while increasing stability

at high speed. Cornering speeds are also higher thanks to the significant increase in

downforce - +87% - which has reached unprecedented levels for a front-engined V12

berlinetta.

A radical redesign of the bodywork, interior, engine, transmission and running gear,

along with the abundant use of carbon-fibre inside and out, has slashed 110 kg off the

car’s overall weight.

.

All of these factors combine to produce record performance figures: 0-100 km/h in 2.9

seconds and 0-200 km/h in 7.9 seconds in addition to a substantial boost in lateral

acceleration. The F12tdf laps Fiorano in just 1’21”.

Outstanding stopping distances are guaranteed by the adoption of the new Extreme

Design one-piece brake callipers already seen on the LaFerrari. This new-generation

system means the car can brake from 100-0 km/h in just 30.5 m and from 200-0 in 121

m.

POWERTRAIN

The engine is the F12berlinetta’s 6262cc 65° V12 on which Ferrari engineers worked

to boost maximum power output from 740 cv to 780 cv at 8,500 rpm, yielding a specific

power output of 125 cv/l. The engine’s sporty response is assured by a maximum torque

figure of 705 Nm (up from 690 Nm) at 6,750 rpm with 80% already available at 2,500

rpm, resulting in unparalleled, progressive pick-up all the way to the red-line at 8,900

rpm.

Numerous modifications have been developed for this engine, starting with the use of

race-inspired mechanical tappets and variable-geometry intake trumpets used on

Formula 1 cars which help boost volumetric efficiency at high revs.

The F12tdf is equipped with a specific version of the F1 DCT with 6% shorter gear

ratios that delivers 30% faster upshifts and 40% faster downshifts.

VEHICLE DYNAMICS

Ferrari’s engineers sought to create an extremely agile and powerful car which could

also be driven by less expert drivers. They drew on the wealth of experience built up in

the XX programmes which are dedicated to developing extremely high performance

cars driven by non-professional drivers.

Extraordinary chassis dynamics, in terms of maximum lateral acceleration and

responsiveness, are in part achieved by the increase in the front tyre dimensions, which

jump from 255 to 275, along with the front channel size - up from 9.5” to 10”. This

modification guarantees higher lateral acceleration generated by the front axle but,

alone, this would have caused oversteer on the limit, making the car more challenging

for less expert drivers.

To enable even gentlemen drivers to make full use of the performance, Ferrari

developed its new Virtual Short Wheelbase system. Debuting on the F12tdf, the rear

axle is active, allowing the rear wheels to pivot around a vertical axis.

Using model-based control logic developed entirely in-house by Ferrari, the rear axle

steering automatically adjusts the rear wheels, working out the optimal steering angle

as a function of the steering wheel angle, speed of steering inputs and vehicle speed.

The Virtual Short Wheelbase improves the car’s responsiveness to make it feel more

agile, with instantaneous turn-in that can be best appreciated on twisty roads and on

more technically challenging tracks while, at the same time, improving stability at high

speeds.

AERODYNAMICS

The F12tdf’s aerodynamic performance is nothing short of record-breaking – its

aerodynamic efficiency figure is 1.6, almost double that of the F12berlinetta.

Downforce is 230 kg at 200 km/h, which is an impressive 107 kg more.

Development affected every area of the car’s surface, producing striking elements that

lend its forms a unique sleek power. At the front, a highly complex bumper contributes

to downforce generation. It features a radically scooped lower section and incorporates

a competition car-inspired splitter, dive planes, floor wings and louvres to boost the

efficiency of both the sides and the underbody.

The Aerobridge on the car’s front flank has been redesigned to increase the energising

effect of the air flow along the top of the sides, while at the rear, louvres on the

wheelarch create a depression that extracts air from the inner wheelarch, thereby

increasing the efficiency of a section of the underbody that is usually little used in

generating downforce.

The rear spoiler is now 60mm longer and 30mm higher, while the rake of the rear screen

has been made more vertical to extend the surface area over which the spoiler can

generate downforce and to capitalise on its advantages more effectively. The concave

curvature of the rear luggage hatch either side of the rear screen further enhances the

solution.

Three pairs of GT-racing-derived strakes have been adopted on the aerodynamic

underbody and are responsible for 30% of the increase in downforce compared to the

F12berlinetta. The rear diffuser has been completely redesigned and now sports a

system of three active flaps. It has been split into three channels and features curved

fences and vertical splitters to boost the power of the vortexes and enhance the

expansion of the flow in the horizontal plane. This radical aerodynamic design work

essentially created a whole new car that also marks a major stylistic departure from the

F12berlinetta.

STYLING

Designed by the Ferrari Styling Centre, the new F12tdf has particularly imposing yet

sensual forms, the product of Ferrari’s continuous commitment to melding sculptural

beauty with functional demands.

All of the bodywork panels, from the chiselled nose to the tail, have been revised. Wider

front and rear tracks also give the car an even more aggressive stance.

In terms of the formal design language, the objective was to create a sophisticated

interaction between the sculptural surfaces of the F12berlinetta and a more graphic

treatment of the various new aerodynamic features. The best testament to this intent is

the evolution of the Aerobridge, the design of which is further enhanced by the use of

bare carbon-fibre. Developed in such a technical manner, this component combines

with the other details in creating a coherent aesthetic approach to the whole car.

The car’s uncompromising sportiness is expressed with the same degree of purity in the

deliberately Spartan cockpit. The wrap-around effect that embraces the driving position

is intensified by the use of carbon-fibre housings for the instruments and satellite pods.

The door panels have been pared back to a single carbon-fibre shell, while the glove

compartment has disappeared to be replaced by simple knee padding. Alcantara rather

the traditional leather was chosen for the cabin trim, technical fabric for the seats and

patterned aluminium instead of mats for the floor, once again with the aim of saving

every last ounce of weight.

The F12tdf’s specification is completed by lightweight alloys with five twinned spokes

that are designed to have the narrowest section possible to reduce unsprung weight.
