Introduction of the Ferrari FXX-K Evoluzione
Recently, in October 2017, Ferrari introduced the FXX-K Evoluzione to the world. The Ferrari FXX-K Evoluzione is an enhanced version of the FXX-K, which both stem from the LaFerrari. Many people believe this is Ferrari’s answer to the Mercedes-AMG Project One. Although the total number of production models is unknown, this car is going to cost a few million. It may be expensive, more so than the FXX-K, but it will be well worth the price increase. Ferrari intends to race the FXX-K Evo in the 2018-2019 racing season which includes 9 track events starting in March 2018.
Electric Motor & V12 Produce 1036 Horsepower
The Ferrari FXX-K Evoluzione sports a V12 engine as well as an electric motor. The V12 produces 850 base horsepower and 553 lb.-ft. of torque. The electric motor produces around 186 base horsepower and 111 lb.-ft. of torque. These engines combine for a total power of 1036 horsepower and 664 lb.-ft. of torque. This power level combines with high-level F1 dual-clutch gearbox to make a mean racing machine.
75% Downforce Improvement Over LaFerrari
Downforce plays an important role in the Ferrari FXX-K Evo. The FXX-K Evo has 23% more downforce than the FXX-K and 75% more than the LaFerrari. This is mostly due to an aerodynamic fixed rear wing. This increase in aerodynamics combined with a weight drop create an engineering marvel. Negative lift is around 1410 lbs at 125 mph and exceeds 1830 lbs near top speed.
Downforce Levels Similiar to GT3 and GTE Championships
The Ferrari FXX-K Evo had 12.5k miles of development and reliability runs prior to its announcement. A lot of testing was done via CFD simulation and in a wind tunnel for aerodynamics. This led to the great numbers mentioned above of a large amount of downforce and negative lift. Ferrari claims that the FXX-K Evo downforce levels are “very close to those of the cars competing in the GT3 and GTE championships.” This statement is clearly true with the numbers that the car is displaying in testing. Track tests with the FXX-K Evo at the Fiorano test track led to impressive results of 1 minute 14 seconds, 5 seconds faster than the LaFerrari.
Ferrari FXX Program
In 2005, the XX Program was started by Ferrari. These cars are for sale to loyal customers who are willing to spend millions for special track versions of cars. These cars are built with the track in mind at a competitive level. Ferrari XX vehicles are usually built in low quantities leading to higher collectibility. Luckily, for those select few, they are collecting pieces of modern artwork.
Carbon Fiber Construction & Twin-Profile Fixed Rear Wing
The Ferrari FXX-K Evoluzione has a carbon fiber construction with a twin-profile fixed rear wing. The fixed rear wing works with an active rear spoiler to optimize downforce. The active spoiler adjusts itself accordingly while in motion. There are 2 side fins as well as a central fin to help with aerodynamics as well. The FXX-K Evo also has redesigned front and rear bumpers. The front has widened front brake air intakes. The rear has enlarged bypass vents on the wheel arches for better flow to the rear diffuser.
Central & Side Fins Boost Stability
The side fins and central fin support the rear wing. The central fin plays an important role on this vehicle. “Firstly it acts as a vertical fin, boosting stability at low yaw angles, and secondly, it supports the action of the three delta (triangular) vortex generators.” Basically, it boosts stability at low yaw angles as well as supports three delta vortex generators. The vortex generators “clean the follow field striking the wing of the effects of the wake of the hot air flow from the radiators which vents onto the bonnet, while also creating a down wash component in the flow which boosts the twin-profile’s downforce capacity.”
Front & Rear Bumper Alterations
As mentioned above, the front bumper is slightly different on this vehicle. “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 vertical turning vane and an additional intake ahead of the front wheels. This system makes good use of know-how acquired in the GT programs in which rules introduced in 2016 permitted extensive study of the interaction between horizontal (flicks) and vertical (dive plane) flow management systems, optimizing their efficiency.” By hollowing out beneath the headlights, Ferrari was able to make space for other important items including additional intake space. All of the changes to the exterior led to the enormous 73% downforce gain over the LaFerrari.
Interior Technology Overhaul
On the inside, there is a “conceptually-different steering wheel”. This wheel includes a KERS Manettino and a 6.5” rear camera screen. The LCD displays telemetry, KERS status, and lap times via the click of a button. All of this combines to enhance the interior layout for additional improvements. This car is beautiful inside and out.
Masterpiece of Modern Automotive Art
Overall, the Ferrari FXX-K Evoluzione is another masterpiece of modern art. From it’s exterior updates to its enormous power capabilities, it is a true beast. The number of vehicles should be very low at a steep price if it follows the usual pattern. We can all look forward to the upcoming racing season to see the potential of this car. In conclusion, will it be a true racing competitor for the Mercedes-AMG Project One?
