<< Prev Page 2 of 2  The vortex generators, on the one hand, clean the flow field striking the wing of the effects of the wake of the hot air flow from the radiators which vents onto the bonnet. On the other, they create a downwash component in the flow which boosts the twin-profile's downforce capacity. The result is a 10% increase in the downforce developed by the rear system.The design of the rear bumpers was also modified in the light of the new flow structures. The by-pass vent from the rear wheel arch has been enlarged, hollowing out the volume behind the wheels to ensure the wake from the wheels is efficiently channelled. The result is that the flow to the rear diffuser is protected and losses are reduced so that downforce has been boosted by 5%. The significant increase in rear downforce demanded in-depth review of the design of the front bumpers and underbody to guarantee a balanced development of the downforce. The geometry of the sides of the front bumper was altered by hollowing out the surfaces beneath the headlights. This made space for a couple of flicks divided by a vertical turning vane and an additional intake ahead of the front wheels. This system guarantees efficient downforce generation (10% of the increase in downforce gained on the FXX-K). It also makes good use of know-how acquired in the GT programmes in which rules introduced in 2016 permitted extensive study of the interaction between horizontal (flicks) and vertical (dive plane) flow management systems, optimising their efficiency. Ground effect was also boosted by the introduction of vortex generators on the undertray. This capitalised on the accelerations created by the rear system and the front underbody, generating 30% of the extra downforce the car delivers compared to the FXX-K. The FXX-K Evo's boosted performance also demanded new front brake air intakes which, although no wider to avoid increasing drag, are more efficient thanks to a complete redesign of the intake itself. Furthermore, the suspension was specifically calibrated to adapt it to the car's new aerodynamic efficiency figures. The clearly racing-inspired cabin is characterised by a conceptually-different steering wheel brilliantly suited to hugely powerful performance levels achievable in the FXX-K Evo. Formula 1 derived with integrated gear-shifting paddles, the new steering wheel now also sports the KERS Manettino to improve both control of that system and overall ergonomics. The rear video camera screen to the right of the driver has been replaced with a larger 6.5" version. It also now displays data from a new telemetry system with clearer, more direct performance parameter and car status readouts. The driver can check the KERS status and the times being clocked by selecting from the various screen options available. After undergoing around 5,000 km of development runs and 15,000 km of reliability test-drives, the FXX-K EVO will be a very active protagonist in the XX Programme in the 2018/2019 season which spans nine track outings in all between the start of March and the end of October. As is now traditional, the XX cars will also be taking part in the prestigious Finali Mondiali weekend which marks the end of each racing season. << Prev Page 2 of 2 |
