The Spyder will be based on the LP670-4 SuperVeloce but will share the same aggressive form as the stealth-fighter Reventon hardtop.
Powered by the same 6.5-litre V12 as found in the LP670-4 SuperVeloce, the Reventon Spyder will develop 500kW to be delivered via an upgraded all-wheel-drive system.
However, don't reach for your cheque book just yet, with only nine examples ever expected to see the light of day, the Reventon Spyder has a rather hefty price tag of - wait for it - A$2.2 million.
Unfortunately however, even if you can afford the price tag, rumour has it that all of the nine cars are already spoken for!
The Lamborghini Reventon Spyder is expected to make its show debut in September at the 2009 Frankfurt Motor Show.
