In the days following the recent Italian Grand Prix, Ferrari’s engineers have been evaluating the effectiveness of a larger fixed rear wing that spans the full width of the car and accompanying aerodynamic addenda during tests at the iconic circuit - filmed by YouTube user 19Bozzy92 in the video below.
The LaFerrari-based hybrid V12 hypercar's new parts will have been developed using Ferrari’s wind tunnel in Maranello, but now full-scale testing will verify if they bring the boost to downforce predicted by aerodynamiscists back at base.
This upgrade process mirrors that used by the brand’s Formula 1 team and is common practice for Ferrari’s track-only models. An ‘Evo’ version of the previous, Enzo-based FXX was launched in a similar vein, with improvements to the car’s bodywork but no major mechanical upgrades.
The same is expected with the FXX K, which uses a naturally aspirated 6.3-litre V12 engine that is assisted by an electric motor driven by an F1-style kinetic energy recovery system. Total system output peaks at 1021bhp.
Before the latest aerodynamic updates, the FXX K already produced 50% more downforce than the road-legal LaFerrari. At its peak, the FXX K generated 540kg of downforce at 124mph. It can lap Ferrari's Fiorano test track in just 1min 14sec, some five seconds faster than the LaFerrari.
