The Lamborghini Murcielago has received a considerable workover for 2008. Now named LP640 in reference to its engine position - longitudinale posteriore - and power of 640 PS (631 hp), the new version of Lamborghini's top model features considerable innovations in terms of body design and mechanics, but remains true to its proven formula. In keeping with its predecessor, the Lamborghini Murcielago is available in both coupe and roadster bodystyles.
A more aggressive exterior
The Murcielago LP640 now appears even more aggressive, with the new front and rear bumpers contributing significantly to its appearance. The exhaust system terminal has been incorporated in the diffuser on the rear bumper. Other innovations include the rear lights, which enhance the distinguishing features of the Lamborghini Murcielago LP640, making it unmistakable even at night. The design of the sides is also worth mentioning: while the area behind the air intake on the right side is practically closed, the left side features a vast aperture for cooling the oil radiator.
For those wishing to flaunt the heart of their Murcielago LP640, on request an engine hood made of transparent glass can be supplied. The rear view mirrors and the windscreen wipers have been modified to improve aerodynamics and Hermera light metal wheel rims have been added. The graphics of the instrument panel lights in the cockpit have been revamped. The interior upholstery also has a new look thanks to the lozenge-shaped stitching.
Engine and Mechanics
The Lamborghini Murcielago LP640 coupe and roadster share a thoroughly modified engine with new cylinder heads and intake system. Increased bore and longer stroke boost the displacement of the classic 60° V12-engine from 6.2 litres to 6.5 litres (6,496 cc). In conjunction with enhanced crankshafts, camshafts, and a new exhaust system, this powerplant now produces 631 hp at 8,000 rpm, up from 580 hp of the preceding version, with a maximum torque of 487 lb-ft at 6,000 min. The “drivability” of the engine is enhanced by a continuous variable timing system (intake and exhaust side) and a drive-by-wire engine management system.
To meet the thermal requirements of the engine, Lamborghini installed a considerably larger oil radiator and subsequently and the air intake on the left-hand side of the vehicle. The liquid cooling system, characterised by the Lamborghini VACS system (variable geometry air inlet system) remains the same. Electronically managed air intakes open depending on the outdoor temperature and the need for cooling air, ensuring maximum aerodynamic efficiency.
To cope with the engine's higher output, the Murcielago 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 Lamborghini Murcielago LP640 features permanent four-wheel drive, based on the 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.
Chassis and Handling Components
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 ½" 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 ZR18 front tires and 335/30 ZR18 rear tires. 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.
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 15.0 in x 1.34 inch and 14.0 in x 1.26 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.
Optionally available are carbon-ceramic brakes featuring six-piston brake callipers. With these high-performance brakes there is almost no perceptible fading even in demanding conditions. Considerably reduced weight and superior lifetime represent two further advantages, as well as a captivating graphic design.
The Murcielago LP640 Roadster's torsional rigidity is improved by newly designed frame structure parts made of steel and carbonfiber guaranteeing an unswerving torsion resistance even without a roof. A special reinforcement structure in the engine area makes a major contribution to this aspect. This optically distinctive reinforcement can also be delivered in carbonfiber on request. Without impairing the extreme character of a typical roadster, a canvas roof (R.top) can be fitted which is principally conceived for temporary use and for speeds of up to 200 km/h.
Interior and Safety
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.
Not as well equipped as some of its competitors, the Lamborghini Murcielago LP640 features front airbags only. Otherwise, safety features are limited to ABS and traction control.
The Murcielago LP640 Roadster has automatically lowered roll bars; if the electronic control of this device detects a critical situation, the roll bars shoot out behind the seats within just a few milliseconds.
Customization
Like its predecessors, the new Murcielago LP640 can be customised thanks to the special fittings and upholstery packages. For the first time, the renowned characteristic Murcielago Roadster asymmetric and driver-oriented fittings and upholstery are available for the Coupe, featuring a perforated leather driver’s seat and door panel.
Thanks to the Ad Personam customisation program, any Murcielago LP640 can be transformed into a customised sports car. For example, the cockpit can be enhanced with a refined carbon finish applied to the air conditioning control panel, the control lever console, and the parking brake.
