Road-going version of Super Trofeo race car to be unveiled on November 19.

Lamborghini has teased a mystery new derivative of its Huracan supercar, ahead of its full unveiling on November 19.

A single image released by the Italian carmaker on its social media pages shows the upcoming supercar under a veil, hiding its tall rear wing and a centrally-mounted roof scoop, and accompanied by the caption “From the racetrack to the road. The new V10 Lamborghini”.

While the car’s identity has yet to be confirmed, it’s widely expected to be the rumoured Huracan STO (standing for Super Trofeo Omologato) – the fastest, most track-focused version of the facelifted Huracan Evo.

As its name suggests, the STO is slated to be a road-going version of the brand’s Huracan Super Trofeo race car and, according to images of a camouflaged prototype posted on Instagram in March, will feature an aggressive race-inspired styling package, large rear wing, elongated rear sharkfin and a roof scoop.

The lattermost upgrade will feed air directly into the engine, which is expected to be a more powerful version of the familiar 5.2-litre naturally-aspirated V10. In the Evo, it develops 471kW of power and 600Nm of torque.

Rumours suggest the STO will tip the scales at around 150kg less than the Evo, with just 700 examples reportedly to be built.

The 2021 Lamborghini Huracan STO will make its public debut via a livestream on November 19, at 2am AEDT.
