The purest concentration of Lamborghini's motorsports prowess, drawn from the Huracan Super Trofeo EVO and GT3 EVO race cars, in a road-homologated supercar.

19 Nov 2020 | International News : Italy

Automobili Lamborghini presents the Lamborghini Huracan STO (Super Trofeo Omologata), a road-homologated super sports car inspired by the racing heritage of Lamborghini Squadra Corse's one-make race series with the Huracan Super Trofeo EVO, as well as its three-time 24 Hours of Daytona-winning and two-time 12 Hours of Sebring-winning Huracan GT3 EVO.

With its V10 naturally aspirated engine producing 631bhp and 565Nm of torque, the rear-wheel drive Huracan STO accelerates from 0-100km/h in 3.0 seconds, 0-200 km/h in 9.0 seconds and has a top speed of 310km/h.

Inspired by the Huracan Super Trofeo EVO and GT3 EVO, the Huracan STO follows those same philosophies and yet is road legal
The Huracan STO sports an entirely new exterior design, revising its inimitable Lamborghini profile to optimise airflow. Every aspect of the Huracan STO draws on the aerodynamic efficiency and lightweight technologies demanded in motorsports.

The front bonnet, fenders and the front bumper are comprised of one single component called the 'cofango'.

This cofango incorporates a new front splitter which, directs airflow to the newly designed underbody of the car and to the rear diffuser. 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 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 rear fender adopts a carbon fibre 'sandwich' technique, which uses 25% less carbon fibre while maintaining the same structural rigidity
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. 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.

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 optimised nolders, are located at the rear.

Using its expertise in lightweight technologies, for the rear fender Lamborghini has adopted a carbon fibre 'sandwich' technique utilised in the aerospace industry, allowing the Huracan STO to use 25% less carbon fibre material while maintaining the same structural rigidity. At a dry weight of 1,339 kg, the Huracan STO weighs 43kg less than the already lightweight Huracan Performante.

The STO has Brmebo CCM-R brakes with four times the thermal conductivity of regular carbon brakes, allowing for more consistent braking
The Huracan STO incorporates a windscreen 20% lighter than the Huracan 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 tyres, available in two versions, one road-focused and 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 a highly responsive and rapid gearshift.

Lamborghini rear-wheel steering, and a more direct and fixed steering ratio, has been to give more feedback to the driver in any driving situation. Every aspect of the STO enhances its ability to corner faster by maximising grip on exit. 

The STO's interior is fitted with carbon fibre and alcantara for maximum weight savings, with even fabric door pulls in place of metal ones
Three new driving modes are available for different driving environments, and these are STO, Trofeo and Pioggia. The default STO mode is for road driving and fun on curving roads.

In Trofeo mode, all systems are optimised for dry asphalt and the fastest lap times on track. The Lamborghini Dynamic Vehicle Integration 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.

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 minimise loss of grip and engine torque cut, with the LDVI system employing precise estimation to deliver only the torque needed in wet situations.

With Brembo CCM-R brakes drawing on materials expertise from F1 applications to deliver superior durability, the CCM-R discs provide four times higher thermal conductivity than traditional CCB. These brakes allows the Huracan STO to stop consistently in all driving conditions while also remaining optimised for track use.

The interior reflects the lightweight persona of the exterior. Carbon fibre is used extensively throughout the cockpit, including the seats, the carpets and the door panels. A rear arch with four-point seatbelts and a newly designed front storage space for a helmet.

The Huracan STO launches with the liveries of Blu Laufey and Arancio California, but owners can fully personalise both the exterior and interior of their STO via the Ad Personam program, with limitless paint and trim combinations as well as race-style vinyls.
