Prior to the Lamborghini Huracan Performante being unveiled at the 2017 Geneva Motor Show, the Italian car manufacturer revealed that it had lapped the Nurburgring in a jaw-dropping 6:52.01, a production car lap record at the time.

In the time since the Performante’s launch, the Huracan range has been facelifted and is now topped out by the STO. Curiously, Lamborghini has made no mention of a Nurburgring lap time with the Huracan STO in the six months since its unveiling but that doesn’t mean it hasn’t been testing the hardcore model at the famed circuit.

During a recent industry pool session at ‘Ring, a Huracan STO wearing a black and yellow paint scheme was spotted completing a series of laps. While most of the laps were performed at relatively slow speeds and in wet or damp conditions, it’s clear the Lamborghini is fine-tuning the car’s on track performance before customer deliveries begin. Will it look to set a flying lap of the Nurburgring with it? We will just have to wait and see.

Like the Huracan Evo, the STO is powered by a 5.2-liter naturally aspirated V10 pumping out 631 hp and 417 lb-ft (565 Nm), all of which is sent through the rear wheels. The car weighs 95 lbs (43 kg) less than the Performante and has been fitted with a host of bold new aerodynamic components inspired by the Squadra Corse race car, including flared arches, a towering rear wing and a unique diffuser.
