Following the success of the fantastic Ferrari LaFerrari, the Prancing Horse decided to also develop its convertible version. It is called Ferrari LaFerrari Aperta and it was officially unveiled during this year Paris Motor Show.
Available with both a carbon-fibre hard top (optional) and soft top, the LaFerrari Aperta boasts the same specification and characteristics as the LaFerrari. It is equipped with the same hybrid power unit as the coupe: an 800 hp 6,262cc V12 engine (specific power output of 128 hp/l, compression ratio 13.5:1) coupled with a 120 kW electric motor for a total power output of a 963 hp.
The powertrain control software has been optimised to increase its overall efficiency thanks to the experience Maranello’s engineers gained with LaFerrari. The dynamic control systems integrated with the active aerodynamics remain unchanged.
Engineering development focused on the chassis and aerodynamics and produced great results. The LaFerrari Aperta delivers the same top speed of over 350 km/h, accelerating from 0 to 100 km/h in in under 3 seconds and 0 to 200 km/h in 7.1 seconds.
The hybrid powertrain generates total torque in excess of 900 Nm: the instantaneous torque from the electric motor is employed at lower revs and V12 engine power and torque is optimised at higher revs. The V12’s peak torque of 700 Nm is, in fact, developed at 6,750 rpm.
The batteries consist of 120 cells assembled into eight modules, with a power output that’s the equivalent of 40 traditional batteries but weighing just 60 kg. The batteries are charged in two different ways: under braking – even hard braking when the ABS intervenes, such as when driving on a track – and every time the V12 produces more torque than required, such as in cornering.v
It also delivers the same torsional rigidity and beam stiffness characteristics, as well as dynamic performance levels. Modifications to the aerodynamic set-up ensure that, with the roof open and the side windows up, the drag figure is unaffected compared to that of the coupe.
A sophisticated wind-stop system, designed to improve aerodynamic and acoustic comfort, means occupants can easily carry on a conversation even at high speeds.
