Murciélago LP640 Roadster benefits from the same extensive
modifications to the bodywork and mechanics as the LP640
Coupé, as well as delivering its own distinct character. In
their re-interpretation of the Roadster, the designers of
the Lamborghini Centro Stile have remained true to the
original style principles of purism, sportiness and
As with the Coupé it has now assumed a more aggressive
appearance, a substantial influence being the new front and
rear bumpers. On the latter there is a new rear diffuser, in
which the exhaust system is integrated within a tailpipe.
The rear lights are also new, increasing the distinguishing
features and making the Murciélago Roadster as unmistakable
at night as in daylight. The asymmetrical design of the
sides is particularly striking. Whilst the area behind the
air inlet on the right is almost closed, on the left there
is a large opening for the ventilation of the oil cooler.
This, in addition to the aerodynamic form of the front and
rear, is an illustration of how functionality dictates the
shape of a Lamborghini. Changes to the rear-view mirror make
the Murciélago Roadster more aerodynamic, with other
features including new windscreen wipers and the option of
new Hermera alloy wheels.
From its forerunner, the Lamborghini Murciélago Roadster
LP640 has inherited the characteristic asymmetrical interior
arrangement. The whole interior is tailored to the driver
and arranged in such a way that a true driver-focused
experience is offered; a car which challenges yet at the
same time is entirely geared to the driver. This is
illustrated in the use of perforated leather for the chair
cushions, the dashboard tunnel console and the door lining
on the driver’s side. The instrument panel has also been
redesigned with different display graphics. This includes a
new Kenwood car radio with a 6.5 inch widescreen monitor and
reader for DVD, MP3 and WMA. The navigation system (standard
equipment in Japan) is also available as an option. Like its
predecessor, the Murciélago LP640 Roadster can be customised
through special equipment packages. The ‘ad personam’
individualisation program offers even more scope to create a
personal, unmistakeably individual sports car.
As with the Coupé the new 6.5 litre (6.496 cm3) 60° V-engine
and 640 PS (471 kW) at 8,000 min-1 is now used also in the
Lamborghini Murciélago Roadster. At 6,000 min-1 the
12-cylinder engine reaches the maximum torque of 660 Nm.
Naturally the Lamborghini Murciélago meets all the current
valid European and North American emission standards. The
increased power naturally leads to increased road
performance. The maximum speed now lies at 330 km/h compared
to 320 km/h. The standard sprint from 0 to 100 km/h is now
reached by the Murciélago LP640 Roadster in an excellent 3.4
seconds making it 0.4 seconds faster than its forerunner.
The engineers also focused their attention on optimising the
torque band. The driveability of the engine thus benefits
from the use of a continually variable timing system (intake
and exhaust side) and engine management with
In order to meet the increased thermal requirements of the
engine, the engineers built a larger oil cooler. On the
exterior this is illustrated by a larger air inlet on the
left wing of the vehicle. The liquid cooler on the other
hand remains unchanged with the Lamborghini VASC System
(variable geometry air inlet system). Additional
electronically controlled air scoops open according to the
outside temperature and cool air requirement. This
guarantees maximum aerodynamic efficiency.
Higher performance and torque naturally mean increased
demand on the drive components. A six-gear transmission
adapted to these requirements, plus a stronger rear
differential and new half-axles, have therefore been
deployed in the new Murciélago Roadster. An e-gear
transmission with a newly tuned thrust mode (acceleration
program) is also available as an option. Like its
forerunner, the new Murciélago Roadster LP640 has permanent
four-wheel drive. This is based on Lamborghini’s proven VT-system
(Viscous Traction), which is self-regulating without the aid
of electronic controls. In standard cases the drive force is
distributed between the front and rear axles at a ratio of
30 to 70. An independent control loop adjusts the
distribution of the drive force depending on dynamic
oscillation, weight distribution and the relative friction
values in synchronisation with the Visco clutch. In extreme
cases, up to 100 percent of the drive force can thus be
applied to one axle.
In their re-interpretation of the Roadster, the
designers of the Lamborghini Centro Stile have
remained true to the original style principles of
purism, sportiness and functionality.
The Lamborghini Murciélago LP640 Roadster benefits
from the same extensive modifications to the
bodywork and mechanics as the LP640 Coupé, as well
as delivering its own distinct character.
Innovations have also been made to the electronics of the
new LP640 Roadster model. With a
closed loop control system the revised electronic control
units improve the road performance and the response
characteristics of the engine. All engine and vehicle
parameters are controlled and monitored through a
combination of three ‘master’ and one ‘slave’ control units.
These are two electronic control units of the Lamborghini
LIE type: a Lamborghini GFA (Gestione Funzioni Ausiliarie,
i.e. Auxiliary Function Control) control unit and a
Lamborghini PMC (Power Motor Control, i.e. slave unit).
These control units are interconnected by means of a CAN
Although the Lamborghini Murciélago Roadster LP640 is
principally based on the Murciélago Coupé, it has further
distinguishing features beyond its distinctive appearance.
First and foremost, newly designed frame structure parts
made of steel and carbon fibre guarantee 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 carbon fibre on
request. Without impairing the extreme character of a
typical roadster, a canvas roof (R.top) can be fitted which,
true to the design tradition of this type of vehicle, is
principally conceived for temporary use (for example in a
sudden shower of rain) and for speeds of up to 160 km/h.
With its characteristic wing doors, the bodywork of the
Murciélago LP640 Roadster is still made from an extremely
high quality combined structure of sheet steel and carbon
honeycomb. The combination of these materials is achieved by
bonding and riveting.
The road performance, handling and stability at high speeds
benefit from the use of new springs and stabilisers as well
as the revising of the electronically controlled silencers.
The anti-dive and anti-squat properties of the axles which
effectively prevent brake diving and squatting, remain
unchanged. The springs (two for each rear wheel and one for
each front wheel) and silencers are coaxially aligned. The
new aluminium Hermera rims measure 8 ½” x 18” at the front
and 13” x 18” at the rear. The vehicle is equipped with
mixed tyres of the type PIRELLI P Zero “ROSSO”: the
Murciélago LP640 Roadster is driven at the front on tyres
with the dimensions 245/35 ZR 18 and 335/30 ZR 18 at the
rear. Pirelli P Zero Corsa tyres are available as an option:
particularly appropriate for use on race tracks.
It goes without saying that a new super sports car such as the
new Lamborghini Murciélago LP640 Roadster goes hand-in-hand
with a high level of safety. Its hydraulic dual circuit
braking system with LP-brake servo (unit) ensures impressive
delay values under even the hardest strain. The internally
ventilated brake disks each measure 380 mm x 34 mm at the front
and 355 mm x 32 mm at the rear. The closed loop of the
four-channel antilock braking system (ABS) is enhanced, with
electronic braking management (DRP) and traction control (TCS).
The system consists of an electro-hydraulic control unit and
four sensors for the wheel speeds. When extremely high
performance braking is required it is possible to equip the
vehicle with carbon ceramic brakes measuring 380 mm x 36 mm
with six-piston-brake callipers, which reduce pressure on
the brake pedal and shorten the braking distance. Even under
the toughest strain, there is almost no brake fading.
Substantially reduced weight and greater durability are
further advantages in addition to the carbon ceramic brakes’
The new Murciélago LP640 Roadster meets rigorous standards
in terms of passive safety. With two front-seat air bags, a
60-litre airbag on the driver’s side and a 130-litre airbag
on the passenger side, the new sports car meets all existing world-wide
standards in the event of head-on and side crashes, impact
against poles, occupant safety in the case of accident, fuel
supply integrity and fuel combustibility. The luggage
compartment also complies with childproof safety
regulations. The Murciélago 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.
