Yesterday, we brought you a video looking at the modifications made to the 6.3-liter V-12 engine in the Ferrari F12 tdf to enable it to deliver all 770 horsepower and 520 pound-feet that the special edition supercar offers. Today’s video highlights the enhancements made to the donor F12 Berlinetta’s chassis to improve dynamics.

The highlight is a new rear-wheel-steering system that Ferrari calls the Virtual Short Wheelbase, or “Passo Corto Virtuale” in Italian. It is integrated with the other vehicle dynamic control systems that help with cornering while also increasing stability at high speed. In the video, Ferrari demonstrates how the system helps to reduce oversteer.
Other changes made to the F12 tdf to improve its dynamics over the standard F12 include weight-saving mods, additional aerodynamic aids, plus larger wheels, tires and brakes. The brakes in particular are a new one-piece design already seen on the LaFerrari. This new-generation system means the car needs just 121 meters to stop from 200 kmh (124 mph), 10 m less than the standard F12.

From the video, we also learn that the F12 tdf can sustain lateral Gs of up to 1.43 and that the steering’s response time is even quicker than the already-quick times of the standard F12.
