Lamborghini has released the first pictures and details of the facelifted Murcielago. It is called "LP640", which implied its 640 horsepower output. (Remark: note that this breaks the tradition of Lamborghini, in which the number following LP indicated engine capacity) The upgraded big Lambo has a heavily redesigned V12 displacing 6.5 liters (up from 6.2). New crankshaft, cylinder heads, camshafts, intake and exhaust means the engine is almost new. Horsepower increases from 580hp to 640hp at 8000 rpm, while max torque inches up from 479 to 487 lbft at 6000 rpm. With the new V12, LP640 can sprint from 0 to 60 mph in 3.3 seconds, or a reduction of 0.4 second. This is partly contributed by the addition of Ferrari-style electronic launch control.
