LaFerrari Aperta: the joy of extreme open-top driving

Ferrari's magnificent Aperta.

Technological excellence, performance, style, exclusivity. These are Ferrari's unique core values which are perfectly represented by the car launched to mark the 70th anniversary of the foundation of the company.

Designed for Ferrari's most passionate clients, the LaFerrari Aperta is the new limited-edition special series, an open-top version of the acclaimed LaFerrari supercar.

Available with both a carbon-fibre hard top (optional) and soft top, the LaFerrari Aperta boasts the same specification and characteristics as the LaFerrari, combining extraordinary performance with the unique exhilaration of open-top driving. It is equipped with the same hybrid power unit as the coupé: an 800 cv 6,262cc V12 engine (specific power output of 128 cv/l, compression ratio 13.5:1) coupled with a 120 kW electric motor for a total power output of a 963 cv.

The biggest challenge involved in designing the LaFerrari Aperta was to produce a convertible that could be pushed to the same extreme limits as the coupé. The Styling Centre's input was concentrated on retaining as much of the original LaFerrari aesthetic as possible. The flowing line that neatly divides the cockpit from the car body is unchanged with only those elements above the waistline modified. The resulting impact is of a carbon-fibre 'flying bridge' hunkered into the main volume.

Engineering development focused on the chassis and aerodynamics and produced absolutely astounding 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. 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 coupé.

The 6,262 cc V12 is the most powerful naturally-aspirated engine ever sported by a road-going Ferrari. It punches out 800 cv and spins to 9,250 rpm, to deliver absolutely extraordinary performance, driving thrills and an unmistakable Ferrari sound.

To boost volumetric efficiency, the V12 employs continuously variable-length intakes - a mainstay in F1 engine technology until banned by rule changes - which optimise performance as a function of engine speed. Similarly, the torque and power curves are optimised across the rev range. 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.

CHASSIS

To retain the same running gear and performance as the LaFerrari coupé in this new open-top model, Ferrari's engineers worked on two main areas: the chassis and aerodynamics.

The elimination of the roof also demanded a review of the door rotation system. The Aperta has the same butterfly doors as the LaFerrari coupé although, when fully open, they are now at slightly different angle as a result of safety-focused re-engineering demanded by its open-top configuration. This in turn led to modifications to the geometry of both the wheelarches and flanks. Specifically, a carbon-fibre insert, which incorporates an aerodynamic vent, was added to allow the doors to rotate. However, the insert itself has also become one of the Aperta's signature styling elements, a flourish that, although absolutely distinctive, does not interfere in any way with the original LaFerrari lines.
