A new optional four-wheel drive system called "Insertable 4×4" is going to debut in the facelifted 612 Scaglietti, that was caught testing in Maranello. The new 612 takes some cues from the 599 GTB Fiorano.
The test equipment on the front wheels is needed to measure the degree of front wheel slip in order to properly calibrate the computer system controlling how much power is being transferred.
The "Insertable 4×4" it is made to to maximize the performance for Ferraris sport cars under all conditions and will work for both mid-engine cars as well as for front-engine cars.
The system it is based on the traditional RWD layout, with the second pair of wheels selectively connected via their new insertable transmission system. Instead of being an all time four-wheel drive system it should rather be viewed as a means of traction control.
