Lamborghini is going after Ferrari’s FXX division with an ultra-limited, track-only model that’ll be revealed by its Squadra Corse racing arm.

The model, which follows on from the road-usable SC18, is now undergoing high-speed track-testing, as shown in a new video released by the firm. Unconfirmed reports suggest the new Aventador-based model will be called the ‘SVR’.

Lamborghini has now confirmed that the track car will take its power from an uprated version of the Aventador's naturally aspirated 6.5-litre V12, with output boosted to 830hp.

The latest video doesn’t reveal much, but it gives a clear visual indication that the new car’s bodywork is far more bespoke than that of the SC18, sharing very little of its profile with the Aventador, as shown in a preview clip from last year.

A wedge-shaped nose with a deep front end and pronounced splitter, a roof-mounted scoop, and a track-bred rear wing design are visible. You also get a quick glimpse of an aggressive diffuser setup.

Last year, Lamborghini’s boss, Stefano Domenicali told our sister publication Autocar UK that it is evaluating an entry into the 2021 Le Mans hypercar category.

Homologation rules dictate that the race version must be strongly related to a road-legal model, with 20 examples required to be produced over a two-year period. That suggests the Le Mans racer isn't likely to be based on this car because it won't be road-legal.
