Limited to just 499 Ferrari collectors, the 458 Speciale A is the most powerful Spider in Ferrari history, marrying extreme performance with the sublime pleasure of open-top driving. Its aluminum retractable hard top actually reduces this model's weight compared to the Speciale coupe by 110 pounds. That folding top also takes only 14 seconds to raise or lower, making a transformation possible even while waiting at a stoplight.
The 458 Speciale A sports the most powerful naturally-aspirated road-going V8 engine ever built by Ferrari with a massive 597 hp at 9000 rpm. A special plaque in the cockpit commemorates three International Best Performance Engine awards won by the powerplant.
The Speciale A sprints to 62 mph in just 3.0 seconds and logs a best Fiorano test track lap time of 1:23.5. These results are due in part to front and rear active aerodynamics, a highly rigid chassis and Side Slip Control (SSC) which furthers sporty driving with a safety net in all conditions. Of course, the soundtrack from the back is quite the symphony, too.

The Speciale A's cabin has a distinctive racing-inspired atmosphere with the focus on eliminating any non-crtical weight. Adopting lightweight, yet exclusive materials including Alcantara and carbon-fiber all crafted with Ferrari’s signature artisanry achieves this goal.
The cockpit design plays on overlapping, layered materials and forms, making it a visual treat.
The glove compartment is replaced with pockets on the tunnel and doors. The familiar Ferrari console bridge with F1 gearbox controls is formed from a carbon-fiber wing, placed at the ideal ergonomic angle to the driver.
Sabelt seats use carbon-fiber shells for strength and light weight. Prodigious side bolstering keeps driver and passenger securely placed during rigorous driving. With Alcantara-trimmed shoulder rests, the seats also provide excellent surface grip. A breathable fabric provides welcomed circulation from the backrests and seat bottoms.
The 458 Speciale A’s body sculpture is chiefly aimed at performance. Most of the bodywork panels have been redesigned without modifying either the passenger cell or the signature design features. Composite bumpers are redesigned and the hood now features two deep air outlets to channel air exiting the radiator.
Air outlets at the sides of the headlight assemblies now also include three louvers reminiscent of the 250 GTO and F40.
The 458 Speciale A is featured in an unusual Yellow, NART Blue and Avus White color scheme and the new forged five-spoke wheels can be specified in Oro, Grigio Corsa or diamond-finish Matt Black at the client's wish.
Making 597 hp at 9000 rpm, the 458 Speciale A’s engine is the most powerful naturally aspirated V8 from Maranello.Read more
A limited-production Ferrari of this type demands an exceptional engine. Making 597 hp at 9000 rpm, it the most powerful naturally aspirated V8 ever from Maranello. Specific output is a world record for a road-going, naturally aspirated engine: 133 hp per liter. The Speciale A also shows an exceptional power-to-weight ratio of 4.97 pounds per hp. Astounding performance numbers result: 0-62 mph in 3 seconds flat; 0-124 mph in 9.5 seconds; and a Fiorano lap time of 1:23.5. To generate additional power over the 458 Italia, components were ambitiously re-examined. Compression rises to 14.0:1 with new pistons, combustion chambers and intake ports are reshaped, a new carbon-fiber intake manifold uses shorter runners, new cams net greater valve lift and a new carbon-fiber airbox is employed. As a group, they equal an increase of 35 hp.
Ferrari draws heavily on extensive F1 knowledge at the design, process and control stages. The engine is produced by factory’s in-house foundry using the same machinery employed by the F1 team, delivering complex components with hyper-critical accuracy.
Optimized combustion chambers and new crankshaft geometry for more frequent high-rpm operation, new intake geometry, and new cam profiles are just some of the work that allowed designers to meet targets. Revised materials with new pistons and connecting rod bushings also play a part. And Ferrari is always weight-conscious. The new carbon-fiber intake manifold and airbox remove 17.6 pounds from the engine compartment.
The soundtrack, both inside and outside, is full-throated and uncompromising with repositioned tailpipes, new mufflers and different intake tracts.
RETRACTABLE HARD TOP
The 458 Speciale A - for "aperta," or "open" - uses the signature innovative retractable hard top of Ferrari Spiders.Read more
Extremely light, compact and functional, the hard top raises of lowers in just 14 seconds. The mechanism actually gives the impression that the two roof sections simultaneously rotate.
The retractable hard top also significantly improves in-car comfort, offering better protection from the elements and improved sound insulation than a soft top and does not deform at speed. Finally, the 458 Speciale A's hard top provides better space and comfort due to its overhead double-curve shape.
The retractable roof also tucks tightly away in front of the engine bay. This compactness is important for superb aerodynamics, attractive rear styling and for the engine’s mid-rear position. Top-down driving is exhilarating, but correct distribution of airflow inside the cockpit is vital for occupants to fully enjoy the top-down experience without off-putting turbulence.
This is why an electric wind stop rises when the hard top has folded away. Wind tunnel research with a full-scale model helped finalize the height and dimension of the deploying wind stop.
The most aerodynamically efficient spider in Ferrari history.Read more
The 458 Speciale A is the most aerodynamically efficient Spider in Ferrari history with coefficient of 1.37, yet with high downforce (Cl: 0.485) and very low drag (Cd: 0.355). Patented active aerodynamics plays a key role, allowing maximum downforce when cornering and minimum drag on straights.
At the front of the car are two vertical flaps in the center with a horizontal flap below them. At low speed, the flaps remain closed, channelling air into the radiators. However, at speeds over 105 mph, the flaps open, reducing air flowing into the radiators, reducing drag. A small forward wing directs airflow under the car, rebalancing downforce to favor the rear end at higher speeds.
Part of the overall increase in downforce is a result of the turning vanes at either side of the front bumper plus aerodynamic fins. The front air dam and the hump at the start of the flat underbody reduce pressure. A larger and more exaggerated rear spoiler creates additional rear downforce.
The 458 Italia’s signature trio of central exhaust pipes are replaced with two exhausts located further apart and higher. A taller underbody diffuser can be fitted to create additional downforce. Active rear flaps raise and lower electronically as required to prioritize downforce or low drag; a similar principle to the one used in F1 with DRS or their Drag Reduction System.
Record-setting technical innovations join traditional, smart engineering.Read more
Record-breaking innovations and decades of mechanical expertise join together in the 458 Speciale A. With new electronics, brakes, suspension calibration and model-specific tires, the laps times drop. Attaining repeatable, high-performance driving thrill without professional-level driving skill goes way up, as well. Response to steering input of 0.060 seconds and lateral acceleration of 1.33 g break the record for a Ferrari production car.
Side-slip control is a new, sophisticated and powerful tool developed with the LaFerrari. It reads the car’s slip angle in real time, setting a target slip angle based on your driving style, and computes how to achieve that through stability control, E-Diff 3 and F1-Trac traction control. With the Manettino set at RACE or CT OFF, the 458 Speciale A's integrated computers manipulate locking torque in the E-Diff 3 in an understeer attitude to lessen it. In an oversteering attitude, the E-Diff 3 unlocks and F1-Trac reduces power to keep to neutralize the slide.
The 458 Speciale’s F1 dual-clutch transmission delivers with much more urgency. Response times quicken, with 20 percent faster upshifts and 44 percent faster downshifts.
Every braking component has evolved from the solutions introduced on the LaFerrari. New Extreme Design calipers, HT2 discs with greater silicon content, and new front pads result in 8 percent shorter stopping distances than the 458 Italia and more consistent performance under severe use.
On-the-limit driving in the 458 Speciale A is easier, faster and sharper thanks to incredibly fast suspension and steering response times combined with more precise body control. Fundamental to this are Frequency-Shaped SCM-E (Frs SCM-E) dampers, which have twin solenoids, a new CPU and new software that modifies the magnetic field inside them every millisecond.
Ferrari and Michelin co-developed specific tires for the 458 Speciale A. Generating 6 percent more grip than the 458 Italia's, the new Michelin Pilot Sport Cup2 tires feature a compound with additives that boost performance over single laps in the dry, consistency over multiple laps, and wet grip. The specially-designed forged 20-inch wheels are also 26.4 pounds lighter than the 458 Italia wheels.
