Racetrack to road: the new Lamborghini Huracán STOOn February 6, 2021 by admin
THE purest concentration of Squadra Corse’s motorsports prowess, drawn from Lamborghini Huracán Super Trofeo EVO and GT3 EVO race cars, in a street-homologated super sports car – we give you the Lamborghini Huracán STO.
With its V10 naturally aspirated 470kW power plant producing 565Nm, the rear-wheel drive Huracán STO delivers exhilarating acceleration of 0-100 km/h in 3.0 seconds, 0-200 km/h in 9.0 seconds and a top speed of 310 km/h.
Superior aerodynamic efficiency, extensive use of lightweight materials, unfettered steering and first-class braking performance, ensure the Huracán STO delivers the emotion of a track experience on every road drive.
“The Huracán STO is the purest incarnation of Lamborghini Squadra Corse heritage, directly transferring technologies from the Huracán Super Trofeo EVO and drawing on the Huracán GT3 EVO’s unique accomplishment of winning three consecutive times in the Daytona 24 hours,” Lamborghini chairman and CEO Stefano Domenicali said.
“The Huracán STO delivers all the excitement of a beautifully balanced, lightweight and aerodynamically superior super sports car, mirroring the driving feeling and exhilaration of Super Trofeo, and perfectly set up for the world’s most demanding tracks but created for the road,” chief technical officer Maurizio Reggiani added.
“The extensive technical solutions and intelligence gained from both our Super Trofeo and GT3 programs has been refined and embodied in the Huracán STO, allowing the pilot to experience the emotions of a racing driver, daily, in a road-legal Lamborghini super sports car able to take lap records.”
Every aspect of the Huracán STO draws on the aerodynamic efficiency and lightweight technologies demanded in motorsports, with the car a result of the collaboration between Lamborghini’s R&D, Squadra Corse and Centro Stile departments.
The comprehensive aerodynamic solutions inspired by Squadra Corse racecars maximise aerodynamic performance, including a front bonnet, fenders and front bumper that are comprised as a single component.
New air ducts on the front bonnet increase the airflow through the central radiator to improve engine cooling as well as helping generate downforce. A new front splitter, directs airflow to the newly designed underbody of the car and to the rear diffuser.
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 per cent decrease in static pressure losses. The revised rear hood design features an integrated air scoop to improve air-cooling.
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. 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 optimises aerodynamic balance and drag resistance according to track characteristics.
A single slotted wing with double air-foil allows the front part of the air-foil to rotate into three positions to enhance rear downforce. It allows for a reduction in the gap between the front and rear air-foil, with compression is increased on the upper side.
This allows it to up the suction intensity and extension on the bottom of the front air foil. The aero balance of the car can thus fluctuate, adapting the STO to different driving conditions.
New front brake cooling ducts built into the front apron provide dedicated cooling for the discs and callipers of the new CCM-R brakes. Additional air intakes included on the underbody, 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.
It uses carbon fibre in more than 75 per cent 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 fibre ‘sandwich’ technique utilised in the aerospace industry.
Thanks to this technology, the Huracán STO uses 25 per cent less carbon fibre material while maintaining the same structural rigidity. At a dry weight of 1,339 kg, the Huracán STO’s weight is reduced by 43kg compared to the lightweight Huracán Performante.
The Huracán STO incorporates a windscreen 20 per cent lighter than the Performante, and features magnesium rims for the highest strength-to-weight ratio, saving further weight over aluminium 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.
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 gearchange speed has been further increased to provide responsive and rapid gearshifts.
Lamborghini rear-wheel steering, and a more direct and fixed steering ratio, has been designed for a race environment and a more intimate relationship between driver, car and track.
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 optimised 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 optimised for dry asphalt and the fastest lap times on track.
The LDVI assures maximum performance through dedicated torque vectoring and performance traction control strategies for both straight sprints, in ESC ON mode, as well for lap timing, in ESC OFF.
The new Brake Temperature Monitoring (BTM) estimation algorithm 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 optimises 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.
Inside, the interior of the Huracán STO reflects the lightweight persona of the exterior: extensive use of carbon fibre features throughout the cockpit, including sport seats in full carbon fibre, and an Alcantara interior with Lamborghini’s Carbonskin.
Carpets have been removed and replaced by carbon fibre floor mats; and the fully carbon fibre lightweight door panels use a door latch as opener. A rear arch with four-point seatbelts and a newly designed front trunk for helmet storage complete the package.
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 analyse the data via the Lamborghini UNICA app.
Owners of the Huracán STO can fully personalise both the exterior and interior of their race car-on-the-road via a rich Ad Personam personalisation program, with limitless paint and trim combinations as well as race-style vinyls.
The concept of a personalised livery is inherent in the design of the Huracán STO, just as Huracán Super Trofeo race cars line up in their unique colours and designs on the starting grid.
The launch livery of Blu Laufey and Arancio California exemplifies the Huracán STO’s young and sporty racing spirit. First customer deliveries should begin in Q2 2021. A local price is yet to be determined, but is expected to be around $405,000 plus LCT/on-roads.
