VIDEO: Ferrari 812 Superfast secrets revealed

Ferrari has released three new videos that explain the radical differences between the 812 Superfast it recently launched at the Geneva motor show and the F12 Berlinetta it's based on.

The first explains how engineers managed to squeeze 588kW/718Nm out of its normally aspirated V12 engine.

The changes are comprehensive.

First, Ferrari bored-out the old F12's 6.3-litre to a 6.5, then engineers redesigned both the inlet and exhaust ducts, introduced variable length inlet ducts (borrowed from an old F1 car) before adding a high-pressure triple injection system.

The result is, LaFerrari aside, the most powerful Ferrari road car engine of all time, a large coupe that can hit 100km/h in just 2.9 seconds and top out at 340km/h.

The next video spills the beans on the Lamborghini Aventador-rival's advanced aerodynamics. The short film shows how the 812 manages to generate more downforce and less drag than the car it replaces.

This involves a new front mounted 'aero cluster' that splits air flow to generate real downforce. The same design element also adds extra ducts for brake cooling, while efficiently channelling airflow to the underbody to reduce drag.

Active aero also plays a huge part in the new aero package of the 812 with vents that open beneath the body and in the big rear diffuser to reduce drag at speeds over 180km/h.

To keep up with the relentless performance, the F12's old dual-clutch auto has also been overhauled to cope.

The new seven-speed 'box, that lives in the rear transaxle, now offers 30 per cent quicker to upshifts and 40 per cent faster downshifts, Ferrari has also given the 812 Superfast bespoke gear ratios to optimise in-gear acceleration.

Dynamically, there's also been a complete rethink to the old F12 chassis with engineers tasked to both improve agility and stability of the big coupe.

The first change was the introduction of a new electric power steering (EPAS) rack in place of the old hydraulic steering.

This enabled Ferrari to add the latest version of its Slide Slip Control that offers a drift mode for the first time. The new EPAS also allows the car maker to integrate its latest stability control system.

New magnetorheological dampers, meanwhile, have also been added that's said to improve body control over the old car.

Biggest change for the 812 is engineers have developed a four-wheel steering system.

Ferrari claim the Virtual Short Wheelbase improves handling by both boosting agility while cornering and increasing stability at high speed.

The rear-steer axle also allows the car maker to use a 10 per cent quicker steering rack and, in Ferrari's words, permits more "steer to throttle" behaviour.

Ferrari hasn’t revealed pricing yet for its heavily updated V12 coupe, but in Europe a price rise is expected meaning Australian buyers will most likely pay more than $690,745 (plus on-road costs) Ferrari Australia charges for the current F12 Berlinetta.
