Sources indicate that it will have even more power than the 478kW V12 Reventon, and also shed at least 110kg from the LP640's 1,665kg body.
Most of this weight loss will be achieved by removing the front differential and driveshafts, effectively making the SV rear-wheel drive.
In addition, most of the interior - from door skins to seat shells - will be replaced with carbon fibre, even going so far as to replace the door handles with a pull strap, all-up saving 2.5kg per door.
This Murcielago R-GT is a good indication of what it may look like.Electronic systems such as for the adjustable spoiler will go, instead opting for a choice of two fixed carbon fibre rear-wings. Forged lightweight alloy wheels will save at least 6kg per corner also.The SV will feature E-gear as standard, not only for prestige and pedigree, but also because it saves weight over a conventional manual.Sources speculate output may rise to as high as 507kW and 699Nm from what may be the final iteration of the 6.5-litre V12 engine.As a result of sending so much power to just two wheels, Lamborghini has also heavily revised the traction control system to keep the horses in check.It could also be the fastest shifting Lamborghini to date, dropping from the current 0.4 to just 0.2 seconds between gear changes.Source: AutoWeek
