The brand new Ferrari 296 Speciale has been engineered to ship one of the crucial superior aerodynamic packages ever seen on a rear-wheel drive street automobile from Maranello, producing 435kg of downforce at 250km/h, a 20 per cent improve over the 296 GTB Coupe.
Talking in regards to the improvement of the 296 Speciale’s aero bundle, Ferrari Aerodynamics Efficiency Engineer Marco Milanetti stated the objective was not solely extra grip, however larger confidence.
“We managed to provide 20 per cent extra downforce to this automobile,” he stated. “However greater than this the goal was to provide accessible efficiency, as a result of you probably have a peak of efficiency however in a really slender window, then sure you’ve got lap time however you don’t have the time to drive that we wished to provide to this automobile.”

Roughly two-thirds of the downforce improve comes from the Speciale’s redesigned underbody. Mr Milanetti defined that Ferrari reworked the diffuser to supply cleaner airflow beneath the automobile.
“One of many principal modification was to convey these vortex mills nearer to the entrance,” he stated. “This will exploit extra downforce. We reviewed utterly the form of the diffuser itself. You may see we had two completely different compartments within the 296, now now we have three virtually equal zones.”
The central channel now creates a deeper low-pressure space that works in live performance with the newly developed aspect wings on the rear bumper.
“We discovered one other optimum, as a result of perhaps it’s not instant however the diffuser and the highest of the automobile, particularly the aspect wings, work actually in a synergic means,” stated Mr Milanetti.
The aspect wings themselves are a mix of the Ferrari FXX Okay and Problem race automobile ideas. “We’ve the horizontal profile, which work actually like wing profile on the exterior aspect, which generates downforce. And on the aspect, now we have these bigger… let’s say we make the automobile bigger and straighter, and this helps the best way the wake is launched downstream.”
On the entrance, the 296 Speciale debuts an Aero Damper, a duct connecting the underbody to the bonnet. Its goal is to stabilise downforce because the automobile’s experience top adjustments.
“It’s perhaps not very evident, however it’s a extremely revolutionary idea, and it offers additionally a number of the boldness that you simply see while you drive. It makes the automobile extra predictable,” Mr Milanetti stated.
The channel hyperlinks the central flooring part with the higher physique, “making its downforce much less delicate.” By venting air upward, the system retains the aerodynamic steadiness constant underneath braking or acceleration, quite than chasing larger peak downforce on the expense of stability.
Ferrari additionally eradicated the central ‘tea-tray’ part of the 296 GTB’s flooring to feed extra energetic airflow to the Aero Damper.
“We eliminated the tray, which was anticipated by way of pure dampers, however was spoiling just a little, taking some vitality from the move that goes on the automobile,” stated Mr Milanetti.
The entrance louvres above every wheel-arch have been added to scale back stress contained in the wheel wells.
“These louvres are designed to attach the high-pressure zone that now we have within the wheel space with the low-pressure underneath the automobile. The air is flowing by means of the louvers and is decreasing the stress within the wheelhouse,” he defined.
“This has an impact additionally on the diffuser, as a result of if we scale back the stress right here within the wheel space, we’re mainly eradicating a blockage for the entrance diffuser.”
Mr Milanetti described how Ferrari’s aerodynamic staff mapped airflow in each wind-tunnel and CFD simulations throughout each potential load situation to make sure the automobile’s reactions stay linear.
“The thought for the aero improvement of those vehicles is to minimise these adjustments as a way to predict simple what the automobile is doing,” he stated. “You have got nonetheless excessive efficiency, however you’ve got a extra predictable behaviour when you drive.”
Ferrari says the mixture of its underfloor redesign, energetic rear spoiler, new aspect wings, and the entrance Aero Damper permits the 296 Speciale to ship track-car ranges of grip and stability with out a corresponding drag penalty.
“The automobile will behave in a different way in braking or acceleration,” Mr Milanetti concluded, “however what we wished was not peak, slender efficiency that solely a grasp driver can exploit, but in addition to have enjoyable, to make it manageable.”
