The STO goes back to the racetrack.
In fall 2020, a hardcore version of the Lamborghini Huracan named Huracan STO arrived from the racetrack to the public roads. Now it is going back to the racetrack in the form of Huracan GT3 EVO2. In simple words, the GT3 EVO2 is a racing version of the STO. Deliveries to customer teams will commence in the second half of 2022, and the previous Huracan GT3 EVO owners can upgrade theirs to the GT3 EVO2 specifications via an evolution kit. Its track debut is slated for the 2023 Daytona 24 Hours.
The Huracan GT3 EVO2 complies with the new FIA 2022 technical regulations while retaining some of the aero elements from the road car, such as the hood outlets, front fender/wing louvers, engine bay louvers, hexagonal airscoop and the rear fin. The airscoop is connected to a snorkel, replacing the side air intakes, which optimally channels the airflow directly into the engine, which is said to result in greater responsiveness to the driver’s demands.
The carbon fibre floor, coated with a high-strength Zylon fiber, together with the new diffuser, is said to offer greater downforce than the current generation GT3 EVO. Other innovations include the rear wing mounted on aluminum alloy pillars—which are said to offer more precise wing adjustments.
The braking system has also been updated with new calipers and pads designed by Squadra Corse. The car rides on 18-inch wheels wrapped with Pirelli PZero tyres measuring 325/680 at the front and 325/705 at the rear. As for safety systems, there’s a redesigned roll cage and new carbon-Kevlar honeycomb side panels; the latter is tested on the Essenza SCV12 and is said to increase safety in the event of an impact on the doors—in compliance with the FIA 2022 regulations. The plexiglass side windows are now fixed to the carbon fibre door panel via a ring of screws for greater structural rigidity and reliability.
The naturally aspirated V10 motor has been hooked up with 10 electronically actuated throttle bodies to increase efficiency; the entire system, designed by Squadra Corse, is fixed to the engine by just four screws, a solution introduced on the Essenza SCV12 for the first time, to facilitate maintenance work.
