Engineers at the Bologna-based dream factory have fi tted the monster machine with a bigger engine — a 6.5-litre V12.
While the 6.2-litre Murciélago had a whopping 426kW, the LP640 has an incredible 471kW.
The engine's torque has also been boosted by 10Nm, to 660Nm.
The current Murciélago can dash from 0-100km/h in just 3.8 seconds. With its extra mumbo, the LP640 can do it in 3.4 seconds. Lamborghini examined every engine component of the Murciélago and changed many to extract as much power as possible.
Changes run from the cylinder head and intake system through to the crankshaft, camshafts and exhaust.
Lamborghini says that it has made the new Murciélago easier to drive thanks to a continuous variable intake and exhaust valve-timing system.
The company has modifi ed the gearbox, the all-wheel-drive system and added a more durable rear differential to handle all the extra punch. Revisions have also been made to the suspension, brakes and electronics.
The exterior has been enhanced with a more aggressive body-kit that suggests this Lamborghini is something extra special. The interior, as well, has been upgraded.
It all sounds pretty awesome, but what about the price? Start saving because it will set you back $659,000 to (carefully) park the LP640 in your driveway.
