Ferrari’s ultra-impressive limited edition F12tdf model relies on more than just its 780PS when it comes to performance, including aerodynamics and vehicle dynamics.
With a 6.3 liter naturally aspirated V12 unit, sending 40 more HP towards the rear wheels than the standard F12 Berlinetta, the limited edition tdf (which stands for Tour de France) is undoubtedly one of the most desirable supercars in the world.
The Italians were also able to improve on the F12 from a technical perspective by increasing the ratio of the front tires in comparison to those at the rear, but also by developing an innovative rear-wheel steering system which they nicknamed Virtual Short Wheelbase.
The front tire dimensions have jumped from 255 to 275, along with the front channel size (increased by 0.5″), therefor guaranteeing the car a higher lateral acceleration.
Of course, by itself this wouldn’t have been enough to steady the F12tdf, which is why Ferrari also came up with the Virtual Short Wheelbase system featuring an active rear axle. Lucky for us, Ferrari have put together a couple of videos demonstrating exactly how these systems work and how much of a performance gain you have in the tdf model compared to the regular F12.
The second video, titled ‘Focus on powertrain’ shows us exactly what modifications have been developed for the naturally aspirated V12 engine, including the race-inspired mechanical tappets and F1-inspired variable-geometry intake trumpets.
The fact that this car can deliver as much as 705 Nm (519 lb-ft) of torque is just as amazing as how soon you can enjoy 80% of that pulling power – available at just 2,500 rpm.
