2016 Ferrari F12tdf




Ferrari revealed 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 in a row. 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.






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 Ferrari 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.

AERODYNAMICS

The Ferrari 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.
