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. 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 hp, 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.
The engine is the F12berlinetta’s 6262cc 65° V12 on which Ferrari engineers worked to boost maximum power output from 740 hp to 780 hp at 8,500 rpm, yielding a specific power output of 125 hp/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.
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.
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.
