Squadra Corse road car: The Lamborghini Huracan STO

Lamborghini unveils their Super Trofeo EVO and GT3 EVO homologation super sports car.

Inspired by the racing heritage of Lamborghini’s Squadra Corse racing division, Lamborghini has brought out their latest V10 road car, based on the Huracan Super Trofeo EVO and the five-time race champion, Huracan GT3 EVO.

It’s called the STO, and it’s the fastest and most aggressive V10 powered car Lamborghini has ever made.

Powering the rear wheels only, the signature 5.2L normally aspirated V10 produces 470kW (640hp) of power and 565Nm of torque, allowing 100km/h to be reached from a standstill in just 3.0 seconds. 0-200km/h takes just 9.0 seconds, as the car rockets up to its 310km/h top speed.

On paper, the acceleration figure is slower than the older AWD Performante, however if Lamborghini was focused on chasing acceleration times, they wouldn’t have made the car rear-wheel drive. The name of the game isn’t straight line speed.

The STO’s advantages come from it’s motorsport prowess, aerodynamics, lightweight solution and race car engineering to create raw and authentic driver feedback.

The exterior design has been completely overhauled to optimise airflow, embodying Lamborghini’s ‘design always follows function’ belief. Designed in collaboration with Squadra Corse and Centro Stile departments, Lamborghini’s R&D have improved on every aspect of the exterior for aerodynamics; every line and every feature optimised to ensure the best driving performance.

The front end is constructed from a single component which Lamborghini engineers call the ‘cofango’ – a combination of the ‘cofano’ and ‘parafango’, or bonnet and fender respectively. This keeps the weight of the panels down to a minimum, and saves time on maintenance out on the race tracks. The Miura was the first to utilise this front end ‘cofango’ approach, and more recently the Gallardo-based insanity called the Sesto Elemento adapted it.

New and large air ducts on the bonnet increase airflow through to the central radiator, serving two purposes; engine cooling and generating downforce. The new front splitter sends air through the underside of the car to the rear diffuser, and the cofango pushes airflow onto the front fenders, where louvers control and maximise airflow exiting the wheel arches. This subsequently reduces pressure and drag inside the wheelhouse, and increases downforce at the front of the car.

The rear has also undergone significant aerodynamic improvements, starting with a new rear fender derived from the Super Trofeo EVO, helping to reduce drag while increasing downforce to improve efficiency. A NACA air intake is incorporated into the STO’s rear fender, and it serves as an engine intake, decreasing static pressure loss by 30%.

The rear engine cover is quite noticeably different, with an air scoop for cooling and new air deflectors to manage the airflow going into the snorkel, adjustible automatically depending on the temperature regulation needs of the engine and exhaust outlets. Additionally, the integration of a ‘shark fin’ is used to improve wind channeling through cornering and sending air to the rear spoiler in the straights.

Speaking of, the rear wing is set-up for maximum track attack with a double airfoil design, and allows for three adjustable positions to enhance downforce at the rear.

In terms of technological changes, the STO gains Squadra Corse engineering. An increased wheel track, stiffer suspension, new anti-roll bars, and electronically controlled MagneRide 2.0 dampers allows for what Lamborghini describes as delivering ‘the emotion of a race car while providing a comfortable road experience’.

The engine has been recalibrated for a responsive racing feel, and engine sound sharpness has been improved at high revs. Gear change response from the 7-speed LDF dual-clutch gearbox has been further increased, and rear-wheel steering has been given a direct and locked ratio, again finessing the track capability of the STO.

Three new driving modes through Lamborghini’s ANIMA system enhance driving enjoyment, from road ‘STO’ to the track ‘Trofeo’ and rain ‘Pioggia’ mode. In STO mode, all aspects of Lamborghini’s Veicolo Dinamica Integrata (LVDI) system are optimised for road conditions, maximising comfort and safety paired with performance.

In contrast, Trofeo mode takes away comfort, as the LVDI system alters the setup for maximum perfomance, controlling the car’s torque vectoring and backing off the traction control. A new Brake Temperature Monitoring (BTM) system uses algorithm estimation to monitor the brake temperature, and allows the driver to manage the wear on the brakes during its life cycle.

Finally, the third ‘Pioggia’ or rain mode optimises traction control, torque vectoring, rear-wheel steering and the ABS for wet road surfaces. TC and the braking system are recalibrated to account for any loss of grip, and all systems work to ensure the car stays at maximum performance despite wet roads.

The interior is perhaps the last thing to focus on with the new Huracan STO. An extensive use of carbon fibre is aimed at keeping weight at a minimum, used for the seats, door cards and many dashboard elements. Alcantara is plastered on top of most non-exposed surfaces, and racing four-point seat belts with a new compartment for helmet storage exemplifies the STO’s need to hit the race track.

Technologically, a new Human Machine Interface (HMI) graphics feature can be found on the touchscreen display, and this manages the drive mode indicator, LVDI system, and displays tyre and brake temperatures. Additionally, a telemetry system allows drivers to monitor and record data via Lamborghini’s UNICA app.

Buyers of the STO are able to customise the exterior and interior colours to their liking, and deliveries begin in Q2 of 2021. Prices start at EUR 249,412 / USD 327,838 – no information on pricing in Australia has been announced as of yet.
