The Ferrari 812 GTS features the newly developed 12-cylinder engine, the power unit that
800 cv makes it the most powerful production convertible on the market.
The aim in developing the 812 GTS was to retain the exhilarating feeling of speed and power delivered by the berlinetta version in terms of accelerating, response times and agility.
The 812 GTS is the spider version of the 812 Superfast, from which it takes both its specifications and performance, most notably the power unit which, thanks to its ability to unleash a massive 800 cv at 8500 rpm, is the most powerful engine in its class. As on the 812 Superfast, these performance levels were achieved in part by optimising the engine design and in part by innovations, such as the use of a 350 bar direct injection system, and the control system for the variable geometry inlet tracts, developed on naturally-aspirated F1 engines. These systems allowed the increase in displacement from 6.2 to 6.5 litres to be exploited to maximise power output whilst retaining excellent pick-up even at low revs.
The aim in developing the 812 GTS was to retain the exhilarating feeling of speed and power delivered by the berlinetta version in terms of accelerating, response times and agility. One of the integrated systems is the Virtual Short Wheelbase 2.0 system (PCV), which has been further evolved based on experience gained since its debut on the F12tdf.
The retractable hard top (RHT), which opens in just 14 seconds at speeds of up to 45 km/h, does not impinge upon the interior dimensions, thus maintaining the donor car’s roomy cockpit. The electric rear screen, which acts as a wind-stop, makes the car truly useable with the top down while, with the top up, it can be left open to allow occupants to continue to luxuriate in the naturally-aspirated V12’s unique soundtrack.
The draped design of the flanks visually shortens the tail and is characterised by sharply slanted crease lines and impressively muscular wheelarches that imbue it with the power and aggression warranted by its imposing V12. On the spider version of the 812 Superfast, the entire rear of the car – roof, tonneau cover and luggage compartment – has been redesigned. The idea was to lend the car a new blend of sleekness and balance, thanks to two buttresses beneath which the roof movement mechanism is stowed.
Meticulously detailed work went into guaranteeing an excellent standard of comfort on-board with the top down. There was huge focus on minimising both turbulence inside the cabin and aerodynamic noise to ensure occupants could converse undisturbed even at high speeds.
As with the LaFerrari Aperta, two small L-shaped flaps on the upper corners of the windscreen generate a coherent concentrated vortex that creates outwash in the velocity field immediately above the rear screen, thereby avoiding excess pressure behind the occupants’ heads.
Aerodynamically, the 812 GTS posed two main challenges for the Ferrari designers: how to guarantee the same performance as the coupé version with the top up and, at the same time, ensure maximum passenger comfort with the roof down.
In terms of pure aerodynamic performance, the retractable hard top and its stowage compartment required that the rear of the car be modified. Thanks to meticulous resculpting of the tonneau cover surfaces and, most importantly, the integration of a triplane wing into rear diffuser to create efficient suction (and thus downforce) from the underbody, the aerodynamicists were able to compensate for the downforce lost by the removal of the 812 Superfast’s rear wheelarch by-pass duct, the air intake of which was behind the quarterlight.
