Photos of a lightly camouflaged Lamborghini Aventador orbiting the Nurburgring Nordschliefe have surfaced, speculated to be a development mule of the upcoming 2015 Lamborghini Aventador SV.
With SV standing for "Super Veloce", this Aventador is expected to be one of the fastest of its breed.
The SV badge can trace its heritage right back to the great-granddaddy of all supercars, the Miura, and, bar the Countach, has been applied to every other top-tier Lamborghini production car since.
Some massaging of the standard 6.5 litre naturally-aspirated V12 is expected to yield roughly 588kW - an increase of 63kW over the Aventador LP 700-4.
With the standard Aventador completing the 0-100km/h sprint in just 2.9 seconds, expect the Aventador SV to slash a tenth or two off that number.
The SV story won't be all about straight-line go, however.
Our spy photos show the SV test mule wearing a modified front bumper and a small gurney flap on the standard retractable rear wing, indicating that the SV will likely produce more downforce and thus more lateral grip than the standard car.
The SV mule also packs some positively enormous brake discs and calipers, as well as a revised wheel and tyre package similar to that used by the Aventador LP 720-4 50 Anniversario Edition.
Other features could include lightweight componentry and a lighter, louder exhaust system.
However with the standard car already featuring extensive use of carbon fibre it's not clear exactly how much weight can be slashed from the Aventador's body - let alone whether it will deliver a measurable benefit.
Whatever the case, the Lamborghini Aventador SV is expected to make its debut sometime towards the end of 2014.
