Driven by Lamborghini test driver Marco Mapelli, the lightweight V10 coupé clocks a 6min 52.01sec lap around the Green Hell.
The video above shows Mapelli hustling the camouflaged model around the 'Ring. The car reaches 188mph, which is 14mph less than Mapelli managed in the Aventador SV on its 'Ring run, but still enough to beat it by 7sec - highlighting the Performante's agility and track focus.
The Performante is due to make its world debut at the Geneva motor show in March. It has been spotted with Becker Carbon stickers, supporting information that it will have ultra-light body panels and will trade metal for carbonfibre in parts of its structure.
Becker Carbon has experience of supplying Formula 1 and Le Mans teams with parts, so its contribution should help the Superleggera significantly undercut the standard Huracán's 1422kg kerb weight.
The bodywork will focus on producing more downforce. Previous test cars for Lambo's lightweight model were spotted with the exterior of a regular Huracán - as shown in older pics in our gallery - but later development cars flaunt large, fixed rear wings, different intakes and a new, less-restrictive twin-exit exhaust system in a raised position, like the Huracán GT3 racer.
The car's mid-mounted 5.2-litre V10 engine is expected to have new fuel injection technology that mixes multi-point injection with stratified injection, as first used on the limited-run Huracán Avio, to produce modest gains over the standard car, which produces 601bhp and 413lb ft.
