Gearbox and transmission: improved efficiency and strength
More power and higher torque call for superior gearbox component performance. To meet these new demands, the new Murci�lago LP640 features a modified six-ratio gearbox as well as a tougher rear differential and new axle shafts. On request, the e-gear automatic gearbox is also available equipped with the new dedicated �Thrust� (acceleration programme) mode.
Just like its predecessors, the Murci�lago LP640 features permanent four-wheel drive, based on the reliable Lamborghini VT (Viscous Traction) system. The system is self-governing and does not feature any electronic controls. The drive force is usually divided between the front and rear axles in the ratio of 30 to 70. An independent control circuit adjusts the distribution of the drive force depending on dynamic oscillation, weight distribution and the relative friction factor in perfect synchronisation with the Visco clutch. In extreme cases, up to 100% of the drive force can be applied to a single axle.
Electronics: a "closed loop" for total control
The electronics have also been updated. The modified engine control units improve engine performance and �driveability� thanks to �closed loop� control.
Every engine and vehicle parameter is managed and controlled by three �master� control units and a �satellite� control unit. The master control units consist of two Lamborghini "LIE" engine control units, a Lamborghini �GFA� (Auxiliary Function Management) control unit and a Lamborghini �PMC� (Power Motor Control) satellite control unit. The control units are interconnected by a CAN Bus line.
Frame and chassis: perfect harmony
The body of the Murci�lago LP640 with its characteristic scissor doors is created from the prized union of sheet steel and honeycombed carbon fibre, glued and riveted together.
Driving, handling and stability at high speed are enhanced by new springs and stabilisers, as well as by a redesigned electronically controlled damper. The "anti-dive" 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 Murci�lago 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.
Brakes and safety: optional ceramic carbon brakes
A super sports car such as the Lamborghini Murci�lago LP640 ensures high safety levels.
The dual hydraulic circuit brake system equipped with a vacuum brake booster ensures considerable deceleration values. The self-ventilating front and rear brake disks measure 380 mm x 34 mm and 355 mm x 32 mm respectively. The control circuit of the four-channel anti-blocking system (ABS) with electronic brake control (DRP) and traction control (TCS) features a new characteristic curve. The system consists in an electro-hydraulic control unit and four speed sensors.
When particularly high braking performance is required, on request it is possible to equip the vehicle with 380 mm x 36 mm ceramic carbon brakes featuring six-piston brake callipers. Thus, less pressure needs to be applied to the brake pedal and the braking distance is reduced. Even in extremely demanding conditions there is almost no perceptible fading. Considerably reduced weight and superior lifetime represent two further advantages, as well as a captivating graphic design.
The new Murci�lago LP640 also meets with even the most rigorous safety requirements. Thanks to the two front airbags (a 60-litre single stage air bag on the driver side and a 130-litre two stage airbag on the passenger side), the Murci�lago LP640 complies with every international law in effect in terms of head-on and side crashes, impacts against posts, occupant safety, fuel supply integrity and flammability of materials. The luggage compartment also complies with childproof safety regulations.
Interior: even more exclusive and customised
The seats in the cockpit have undergone the most radical changes; more spacious and equipped with redesigned head restraints, the seats now ensure better comfort. The leather upholstery features lozenge-shaped stitching called "Q-citura". The same design is recaptured on the upholstery on the door panels, the panel between the seats and the engine compartment, and on the roof panel.
A new instrument panel has been developed with lights featuring a new graphic design, flanked by a new Kenwood car radio with a 6.5� widescreen monitor and DVD, MP3 and WMA player. An optional navigation system is also available (standard in Japan).
Like its predecessors, the new Murci�lago LP640 can be customised thanks to the special fittings and upholstery packages. For the first time, the renowned characteristic Murci�lago Roadster asymmetric and driver-oriented fittings and upholstery are available for the Coup�, featuring a perforated leather driver�s seat and door panel.
Thanks to the "Privilegio" customisation program, any Murci�lago LP640 can be transformed into a customised sports car. For example, the cockpit can be enhanced with an extremely refined carbon finish applied to the air conditioning control panel, the control lever console and the parking brake.
