A Site Dedicated to the Cars I One Day Hope to Own

Lamborghini introduces an even better Murcielago in the LP640 with the LP standing for its engine position - longitudinale posteriore - and 640 for its horsepower.  Almost everything has been improved from the engine, suspensions, gearbox, exhaust system, brakes and electronics.  The increased bore and longer stroke have boosted the displacement of the classic 60" V-engine from 6.2 litres to 6.5 litres resulting in a 60 HP increase to  640 HP @ 8000 RPM and an increase of peak torque to 487 ft-lbs. at 6000 RPM.  The result is a 0-62MPH time of 3.4 seconds which is .4 seconds faster than the normal Murcielago.   

Driving, handling and stability at high speed are enhanced by new springs and stabilisers, as well as by a redesigned electronically controlled damper. The "antidive" and "anti-squat" features on the axles, which efficiently prevent so-called "brake diving" and "squatting", have not been changed. The two springs on every rear wheel, the single spring on every front wheel and the damper are placed coaxially. The new aluminium "Hermera" rims measure 8 " x 18" (fore carriage) and 13" x 18" (rear axle). The vehicle can be fitted with various sized Pirelli P Zero "Rosso" tyres. The Murcielago LP640 features 245/35 ZR 18 front tyres and 335/30 ZR 18 rear tyres. For sports use, especially on racetracks, Lamborghini provides optional Pirelli P Zero "Corsa" (Race) tyres. Pirelli P "Sottozero" (Sub zero) winter tyres are currently being developed.  Optional carbon ceramic brakes are also available. 

Styling wise, the LP640 features revised front and rear bumpers with the exhaust system terminal incorporated into the rear bumper.  On the side, while the air intake on the right is practically closed, the left side is wide open to cool the oil radiator.  A clear engine cover is also available to show off the beauty that is 12 cylinders.  Lightweight 18inch "Hamera" wheels have also been added.
