The
Huracán STO is the result of the collaboration between Lamborghini’s R&D,
Squadra Corse and Centro Stile departments. The comprehensive aerodynamic
solutions inspired by Squadra Corse race cars maximize aerodynamic performance.
The
front bonnet, fenders and the front bumper are comprised of one single
component: the ‘cofango’ created by Lamborghini engineers combines the ‘cofano’
(hood) and ‘parafango’ (fender) including the front bumper, inspired by the
Lamborghini Miura and more recent Sesto Elemento. It is not only lightweight,
but also a time-saving access feature in motorsports.
New
air ducts on the front bonnet increase the airflow through the central radiator
to improve engine cooling as well as helping generate downforce. The cofango
also incorporates a new front splitter, directing airflow to the newly designed
underbody of the car and to the rear diffuser.
The
cofango is shaped to push the airflow on top of the front fenders, which
incorporate louvers to maximize airflow exiting from the wheelhouse, reducing
pressure inside and increasing the front downforce. The side profile of the
cofango directs airflow around the front wheels, reducing drag.
A
new rear fender derived from the Super Trofeo EVO achieves both reduction of
the front area of the car and consequently the drag, while increasing rear
downforce and the car’s overall aerodynamic efficiency. A NACA air intake
integrated into the STO’s rear fender serves as an engine air intake, with the
shortened duct allowing a 30% decrease in static pressure losses.
The
revised rear hood design features an integrated air scoop to improve
air-cooling at the rear underhood. Dedicated
air deflectors, integrated in the rear bonnet’s frame, manage the significant
incoming airflow from the snorkel according to the temperature regulation needs
of the engine and exhaust outlet.
An
integrated ‘shark fin’ on the rear bonnet improves the dynamic abilities of the
STO, particularly when cornering: in such conditions the incoming airflow has a
yaw angle, and the different pressure levels generated by the two sides of the
fin create a positive effect on yaw stability. The fin also helps straighten
airflow onto the wing, increasing wing efficiency during cornering.
A
manual, easily-adjusted aero set-up of the new rear wing optimizes aerodynamic
balance and drag resistance according to track characteristics. A single
slotted wing with double airfoil allows the front part of the airfoil to rotate
into three positions to enhance rear downforce. By reducing the gap between the
front and rear airfoil, compression is increased on the upper side, upping the
suction intensity and extension on the bottom of the front airfoil. The aero
balance of the car can thus fluctuate by 13%, adapting the STO to different
driving styles and conditions.
New
front brake cooling ducts are dedicated to cooling the discs and calipers of
the new CCM-R brakes, working in conjunction with the cofango air-louvers that
dispel hot air from the front wheelhouses. Additional air intakes including on
the underbody, and optimized nolders, are located at the rear.
The
Huracán STO achieves the highest level of downforce in its class with the best
aero balance for a rear-wheel drive car, with delivery of a superior
aerodynamic load a key factor in its enhanced cornering performance. Overall
airflow efficiency is improved by 37% and a significant downforce increase of
53% is reached over the Huracán Performante.
The
Huracán STO uses carbon fiber in more than 75% of its exterior panels,
benefiting from complex structures produced as a single component for increased
integrity while also reducing weight via less fixing points. Using its
expertise in lightweight technologies, for the rear fender Lamborghini’s
R&D department has adopted a carbon fiber ‘sandwich’ technique utilized in
the aerospace industry. Thanks to this technology, the Huracán STO uses 25%
less carbon fiber material while maintaining the same structural rigidity. At a
dry weight of 1,339 kg, the Huracán STO’s weight is reduced by 43 kg compared
to the already lightweight Huracán Performante.
The
Huracán STO incorporates a windscreen 20% lighter than the Huracán Performante,
and features magnesium rims for the highest strength-to-weight ratio, saving
further weight over aluminum alloys with the same load factor.
The
magnesium rims are fitted with bespoke Bridgestone Potenza tires, available in
two versions: one road-focused, the other more track oriented. Both designs
combine innovative compounds with a finely-tuned footprint efficiency, thereby
enhancing driving precision and adherence in a wide temperature range.
The
Huracán STO has at its heart the V10 aspirated engine of the Huracán EVO and
Super Trofeo, outputting 640 hp (and 565 Nm of torque at 6,500 rpm. With an
increased wheel track, stiffer suspension bushing, specific anti-roll bars and
Lamborghini’s MagneRide 2.0, the STO delivers all the emotion of a race car
while providing a comfortable road experience. The engine has been calibrated
for a very sporty and responsive racing feel, with a direct pedal-to-throttle
feeling and improved engine sound sharpness at high revs. The gear change speed
has been further increased to provide a highly responsive and rapid gearshift.
A
more direct and fixed steering ratio, including Lamborghini rear-wheel
steering, has been designed for a race environment and a more intimate
relationship between driver, car and track: the driver is fully in touch with
the asphalt with feedback on the car’s behavior at his fingertips. Every aspect
of the STO’s racing heritage and technology enhances its ability to corner
faster, maximizing grip on exit: the Huracán STO is confirmation that races are
won in corners rather than on straights.
Three
new driving modes exemplify the Huracán STO’s racing spirit, focused on high
performance driving environments: STO, Trofeo and Pioggia. The default STO mode
is for road driving and fun on curving roads. Every aspect of the Lamborghini
Veicolo Dinamica Integrata (LDVI) vehicle dynamics system is optimized for all
road conditions and coupled with a road-oriented suspension setting. The
fully-active ESC can be switched off for maximum driving fun while still
supporting the driver.
In
Trofeo mode, all systems are optimized for dry asphalt and the fastest lap
times on track. The LDVI assures maximum performance through dedicated torque
vectoring and performance traction controlstrategies for both straight sprints,
in ESC ON mode, as well for lap timing, in ESC OFF. The new brake temperature
estimation algorithm (BTM) allows the driver to constantly check the braking
system’s temperature, and to manage wear of the system during its life cycle.
Pioggia
(rain) mode optimizes traction control, torque vectoring, rear-wheel steering
and the ABS on wet asphalt. Traction control and the braking system are
calibrated to minimize loss of grip and engine torque cut, with the LDVI system
employing precise estimation to deliver only the torque needed in wet
situations. The torque vectoring reflects the low adhesion conditions and
ensures better cornering, while the suspension is calibrated to maximize grip
and improve load transfer.
The
motorsports DNA of the Huracán STO is as evident in its braking system. With
CCM-R brakes drawing on materials expertise from F1 applications to deliver
superior durability, the CCM-R discs provide four-times higher thermal
conductivity. Stress resistance is 60% higher compared to traditional CCB, with
maximum brake power improved by 25% and longitudinal deceleration by 7%. This
results in robust braking consistency in all driving conditions: braking feels
sporty, can be perfectly modulated, and thus is optimized for track use.
The
interior of the Huracán STO reflects the lightweight persona of the exterior:
extensive use of carbon fiber features throughout the cockpit, including sport
seats in full carbon fiber; an Alcantara interior with Lamborghini’s
Carbonskin; carpets removed and replaced by floormats in carbon fiber; and the
fully carbon fiber lightweight door panels with a doorlatch as opener. A roll
bar with four-point seatbelts and a newly designed front trunk for helmet storage,
underline the Huracán STO’s racing DNA.
New
Human Machine Interface (HMI) graphics feature on the Huracán’s touch screen,
which manages the car’s functions including drive mode indicator, the LDVI
system, tire pressures and brake temperatures. A fully-connected telemetry
system allows pilots driving their Huracán STO on racetracks to monitor and
record their performance and to analyze the data via the Lamborghini UNICA app.
