Lamborghini has once again teased its hyper-flagship, this time making some bold claims about its performance credentials.

Lamborghini has previewed its upcoming Aventador SVJ again this week, releasing a new video clip online.

While the video itself doesn't feature any commentary regarding details of the upcoming supercar flagship, the caption does highlight that the new model is "designed to have the best weight to power ratio" – or power-to-weight ratio.

Lamborghini doesn't explicitly give a figure that will make the SVJ's power-to-weight ratio the "best", though the video does show company test driver, Marco Mapelli, thrashing the camouflaged Aventador around the Nurburgring.

Additionally, there's a quick flash of 'Trofeo R' lettering on the car's tyres, confirming the new model will come fitted with Pirelli's track-ready rubber.

Compared to the 'standard' version, the Aventador SVJ is expected to get an uprated engine, enhanced aerodynamics and a reduction in weight like the Huracan Performante.

The Aventador S currently makes 544kW and 690Nm from its 6.5-litre naturally-aspirated V12, and the SVJ is said to push the 600kW barrier with a pumped-up version of the same motor.

With that in mind, the SVJ should undercut the S's 2.9-second 0-100 claim, along with the 8.8 seconds Lamborghini says it takes the S to reach 200km/h from a standstill.

The biggest improvements, however, should be apparent on the track, with the aerodynamic upgrades and lighter weight contributing to improved handling and better lap times – perhaps a new attempt at the Nurburgring record is in the pipeline.
