Press Release) Lamborghini Sesto Elemento – An extreme
lightweight in carbon fiber for sensational performance and handling
Lamborghini is
redefining the future of the super sports car with a unique
technology demonstrator. Boasting an extremely lightweight
construction thanks to advanced carbon-fiber technology, the
Lamborghini Sesto Elemento has an overall curb weight of just 999
kilograms (2,202 lb) – including V10 power unit and permanent
all-wheel drive. This makes the Sesto Elemento a unique
demonstration of the technological expertise of Automobili
Lamborghini. Innovative carbon-fiber technologies are being used
here for the first time in an automotive application. As a 100
percent subsidiary of AUDI AG, the Italian carmaker also benefits
from the undisputed expertise of the German manufacturer when it
comes to lightweight construction.
With its amazing output of 570 hp, sensational power-to-weight ratio
of only 1.75 kilograms per hp and 0 to 100 km/h (0-62 mph)
acceleration of only 2.5 seconds, the Sesto Elemento guarantees
unparalleled driving fun. At the same time, fuel consumption also
drops because of the extreme lightweight engineering applied
throughout.
The name of this technology demonstrator is derived from the
periodic table, where carbon is classified as the sixth element.
Thus, the Sesto Elemento demonstrates the worldwide leading
expertise of Lamborghini in carbon-fiber reinforced plastics (CFRP)
technology. The super sports car brand from Sant’Agata Bolognese is
the only vehicle manufacturer in the world to have mastered the
complete CFRP process across a range of technologies, from 3D design
through simulation, validation, production and testing – all in a
state-of-the-art industrial process that stands for the very highest
quality standards.
Lamborghini drives the technology development in its two research
centers the ACRC (Advanced Composite Research Center) and the ACSL
(Advanced Composite Structures Laboratory) through collaborations
with organizations such as Boeing, with the resulting technology
secured under a host of patents.
“The Lamborghini Sesto Elemento shows how the future of the super
sports car can look – extreme lightweight engineering, combined with
extreme performance results in extreme driving fun. We put all of
our technological competence into one stunning form to create the
Sesto Elemento,” comments Stephan Winkelmann, President and CEO of
Automobili Lamborghini. “It is our abilities in carbon-fiber
technology that have facilitated such a forward-thinking concept,
and we of course also benefit from the undisputed lightweight
expertise of AUDI AG. Systematic lightweight engineering is crucial
for future super sports cars: for the most dynamic performance, as
well as for low emissions. We will apply this technological
advantage right across our model range. Every future Lamborghini
will be touched by the spirit of the Sesto Elemento.”
Groundbreaking technology package
With the Sesto Elemento,
Lamborghini’s R&D engineers have put together a groundbreaking
package. As a pure and radical concept, the Sesto Elemento is the
unique synthesis of an extremely low curb weight of less than 1000
kilograms, enormous 570 hp output, the sensitive and prompt
responsiveness of the high-revving, naturally-aspirated V10 engine
and the superior traction and stability of permanent all-wheel drive
– there has never been a super sports car as thoroughbred as this.
Sesto Elemento delivers an unbelievable degree of driving fun,
concentrated on absolutely sensational dynamics.
Systematic use of carbon fiber
The basis is an
extremely solid, stiff, safe and lightweight carbon-fiber structur:
the monocoque cell of the Sesto Elemento. The entire front frame,
the exterior panels and crash boxes are also made from CFRP. The
Sesto Elemento’s major suspension components and the rims are made
from carbon fiber. The tailpipes are made from Pyrosic, which is an
advanced glass-ceramic matrix composite, able to reach and stand
very high temperatures up to 900° celsius. Even the propeller shaft
is made of CFRP.
Amazing power-to-weight ratio
The Sesto Elemento
demonstrates the outstanding expertise of Automobili Lamborghini in
all areas of carbon-fiber technology. Carbon composite materials are
a key technology for the automotive engineering of tomorrow,
especially for high-performance sports cars. These materials made
from carbon-fiber reinforced plastics combine the lowest weight with
excellent characteristics – they are extremely stiff and highly
precise. Lighter cars improve fuel consumption and CO2 emissions:
above all, however, it improves the power-to-weight ratio – the
crucial factor for a sports car – and thus the performance. A super
sports car built using CFRP accelerates faster, has outstanding
handling and better braking.
Extreme lightweight engineering
delivers extreme performance
The Lamborghini Sesto
Elemento offers the ultimate proof; thanks to its sensational
power-to-weight ratio of only 1.75 kilograms per hp, the concept car
delivers unparalleled performance. From a standing start, the Sesto
Elemento catapults itself to 100 km/h (62 mph) in a sensational 2.5
seconds. In the interests of completeness, it should also be
mentioned that the top speed is well over 300 km/h. What the figures
cannot convey, however, are the Sesto Elemento’s razor-sharp
handling, its voracious turn-in and its huge braking power. Extreme
lightweight engineering and extreme performance come together in the
Sesto Elemento to create an all-n
Design: Technology in a
progressive form
Uncompromising dynamics
from the very first glance: the design of the Lamborghini Sesto
Elemento displays the sensuality of high performance and possesses
the elegance of pure, unadulterated power. The Sesto Elemento lifts
the design DNA of the Lamborghini brand to a new level and
integrates the functional consistency of carbon-fiber technology
into its design language. A clear strength of the CFRP technology is
the reduction and integration of components – something that has
been used to its full extent in this innovative technology concept.
The hi-tech material is visible everywhere. The Sesto Elemento is
finished in a new, matt-shimmer clear coat, meaning that the CFRP
structure can be seen throughout. Yet the Sesto Elemento is not just
black; during the final stage of production the carbon fiber parts
receive a newly developed and patented coat. Nano-Technology makes
it possible to add fine crystals with a red shimmer. Surfaces
covered with this type of finish glow red and deliver an outstanding
effect. Further, the surface is particularly robust.
Consistent in form and function
On a Lamborghini, every
single line has a clear function; the two vertical ribs at the
front, for example, improve the stiffness of the component and guide
the cooling air directly to the radiator behind them and to the
brakes. This guarantees the thermal wellbeing of the components even
under the toughest race track conditions.
The cooling air flows through two red triangular openings in the
hood beneath the front windscreen and through large outlets in the
side panels behind the front wheels. Sharply cut headlamp units
complete the front end. Reduction is the name of the game here, too
– alongside the bi-xenon lamps, there are four LEDs in each unit.
The low front end looks incredibly dominant, with the partially
double-lipped front spoiler pushed way out front and distinctively
formed air intakes.
Precise lines, sharp edges
The entire side profile
is cut like a sharp wedge, with the power center of the car
unmistakably just in front of the rear axle. A distinctive sideline
starts at the front wheel arch, rises along the door towards the
rear and ends at the broad shoulders above the rear wheel. The
triangle – like the one around the door handle - is a recurring
design theme, defined by the precise contour edges in the Sesto
Elemento’s CFRP body. The points of the air outlet triangles in the
hood are carried through into lines along the roof.
The extremely wide sills form a connection between the air outlets
behind the front wheels and the large air inlets in front of the
rear wheels. These compartments house components such as the
radiators for cooling the engine and transmission oil. The rims have
a five-spoke design and are made entirely from carbon fiber. They
offer a clear view of the high-performance brakes with
carbon-ceramic discs.
Perfect aerodynamics
The Sesto Elemento’s
rear overhang is extremely short and, again, defined by optimum
aerodynamics. The generously dimensioned spoiler is perfectly
matched to the diffuser and a further air deflector in the center,
thus guaranteeing maximum downforce for extreme cornering speeds and
excellent high-speed directional stability. The Pyrosic tailpipes
are directed upwards through the engine cover panel, which also
incorporates ten hexagonal openings and two air scoops behind the
roof for delivering fresh air to the V10 power plant.
Complex structures in one
component
A major strength of
carbon-fiber technology is that complex structures can be integrated
into one single component. This improves quality and reduces weight.
On the Lamborghini Sesto Elemento, the front and rear of the
body-shell are each manufactured in a single piece. Engineers call
this “cofango”, created by combining the Italian word “cofano”
(hood) with “parafango” (fender). The large components are attached
by using easily removable fasteners, in order to have fast component
disassembly. The “cofango” is also reminiscent of an icon from the
brand’s history: in 1966, the legendary Lamborghini Miura was unique
as a mid-engine super sports car – and its rear cover, too, could be
opened in one piece.
Interior – pared to the bone
The minimalist approach
has also been applied to the interior, starting with the seats.
Lamborghini has dispensed completely with the conventional seat
frame. In fact, the whole internal structure is obtained and defined
directly from the Forged Composite tub, that on one side plays a
functional role and on the other side is the base for the optimally
formed seat cushions, upholstered in hi-tech fabric, which are
affixed directly to the carbon-fiber monocoque. The correct
ergonomics are provided by the steering wheel, which can be adjusted
for height and reach, and by the pedals, which can be electrically
adjusted longitudinally. Of course, the designers of Lamborghini
Centro Stile also dispensed with interior trim in the classic sense.
The dominant visual feature throughout is the functional CFRP
material – on the floor and roof of the monocoque, on the doors and
also on the cockpit and center console. Even the electronic control
unit for the engine is mounted in plain sight – a very special kind
of hi-tech aesthetic. The triangular cut-out is also evident as a
design feature – wherever material can be removed in the interest of
weight reduction.
The controls are presented in a highly concentrated format. The
instruments provide information primarily on engine and road speed,
as well as all parameters relating to engine condition. Only three
piezoelectric buttons grace the center console – one to start the
engine, one to shift into reverse gear and another one for the
lights.
Technology: Ambitious target
reached with ease
The Sant’Agata Bolognese
engineers had set themselves a target that was more than ambitious –
despite the ten cylinders and 570 hp, despite the exceptionally
fast-shifting e.gear transmission and even despite the permanent
all-wheel drive, the Sesto Elemento still had to stay below the
1,000 kilogram mark. And that target was achieved; at a curb weight
of 999 kilograms, each hp produced by the V10 power unit has to
accelerate only 1.75 kilograms – a sensational figure.
This was made possible by the systematic and intelligent use of
state-of-the-art carbon-fiber technologies. Lamborghini possesses
extensive experience in the field of lightweight engineering,
gathered over many years: something clearly demonstrated by the
brand’s series production vehicles. The current Gallardo LP 570-4
Superleggera has a dry weight of only 1,340 kilograms, marking a
competitive best in this category of super sports cars. Compared
with the already extremely lean Gallardo LP 560-4 Coupé, this
represents a further reduction of 70 kilograms, resulting largely
from the use of carbon fiber in the body-shell, interior and
technical components.
Lamborghini engineers stuck firmly to this approach for the Sesto
Elemento. Its structure consists almost entirely of carbon fiber and
is built using the monocoque principle. Monocoque means that the
vehicle’s load-bearing structure is manufactured as a single shell,
with the physical properties of one component, and thus makes
optimum use of the extreme stiffness offered by CFRP materials.
Formula 1 racing cars have been built using CFRP monocoques for
decades – and regularly provide clear evidence of their collision
safety. The monocoque in the Sesto Elemento, however, is made using
innovative Forged Composite technology – the first time this has
been done in an automobile. The advantage of the Forged Composite is
that the monocoque is obtained through a one-shot process.
Carbon-fiber crash boxes
In the Lamborghini Sesto
Elemento, the monocoque forms the complete passenger cell. Connected
to it are the front subframe - incorporating the suspension points -
and the crash boxes, both also made using specialized carbon-fiber
technologies. The extreme stiffness of this assembly guarantees not
only a very high level of safety, but also unparalleled handling
precision. The rear subframe with the engine mount and rear axle
suspension points is made from aluminum – another lightweight
material with which Lamborghini has a great deal of experience.
An important element in optimum construction using CFRP technology
is the maximum integration of functions. Thus, the body-shell
exterior is made up only of the roof section, which is part of the
monocoque, the two “cofango” covers front and rear with integrated
aerodynamic components and the doors. Each door consists of only two
elements, the exterior skin and the interior cladding, both of which
are also permanently bonded to create one component.
Carbon fiber even in the
suspension
The suspension and the
area around the engine have also been optimized with lightweight
engineering. Alongside aluminum components, there are also
carbon-fiber control arms: innovative Forged Composite technology is
also well-suited to this kind of high-load part. These components
are around 30 percent lighter than comparable aluminum parts. The
propeller shaft is also made of CFRP by using Wrapping technology.
This solution allowed the Lamborghini engineers to get rid of the
central joint, bringing an important weight saving. The rims are
also made from CFRP, while the brake discs are from carbon-ceramic
composite material. A similar composite material is used for the
tailpipes on the exhaust system – the compound of ceramic powder and
synthetic resin makes this carbon material extremely heat resistant.
A large number of screw fastenings feature a special titanium alloy
and joining technology from the aviation sector.
Based on the form, function and operational demands of the
individual Sesto Elemento components, engineers from Lamborghini’s
R&D selected largely from three CFRP manufacturing techniques within
their technology tool kit:
Forged Composite:
Here, materials with short carbon fibers are hot pressed in a
mould. The process facilitates complex structures and is used
for parts such as the underside of the monocoque and the
suspension arms.
Prepreg: The carbon-fiber mats are soaked in a thermoset
liquid resin. They are pressed in moulds and cured in an oven
under heat and pressure. Prepreg components have a very good
surface finish and are therefore the preferred choice for use in
visible areas.
Braiding: This is a method to manufacture composite
filament derived from the textile industry. Each thread is
diagonally intertwined on different levels.
Drive: Concentrated power and
amazing sound
The fascinating heart of
the Lamborghini Sesto Elemento is familiar from the Gallardo LP
570-4 Superleggera. In the Sesto Elemento too, the V10 unit is
mounted “longitudinale posteriore” – longitudinally behind the
driver. The 570 hp output equals 419 kW, all of which is available
at 8,000 r/min. The pulling power is just as impressive – with the
torque curve peaking at 540 Nm and 6,500 r/min.
The V10 offers 5,204 cm3 of displacement, delivering a specific
output of 80.5 kW (109.6 hp) per liter of displacement. The
highlights of this long-stroke engine with an aluminum crankcase
include dry sump lubrication and a cylinder angle of 90 degrees.
Both solutions are an integral part of the lightweight engineering
approach, as well as serving to lower the center of gravity and thus
tighten the handling characteristics. Ideal combustion chamber fill
comes courtesy of a switch-over induction system and continually
variable, chain-driven camshafts.
Best traction with all-wheel drive
The Sesto Elemento is
equipped with the e.gear transmission, controlled in race car
fashion via shift paddles mounted on the steering wheel. The
automated system with electronic management shifts smoothly through
its six gears much faster than a human being would be able to.
Every single kilometer in the Sesto Elemento is sheer fascination –
due in part to the relentless traction delivered under practically
all conditions. This is largely attributable to the permanent
all-wheel drive system. It incorporates a central viscous coupling
and a self-locking differential for the rear wheels with 45 percent
lock. Thanks to this superior traction, Lamborghini drivers can
accelerate earlier out of a curve than those in rear-wheel drive
cars.
Competence: New development
center for carbon-fiber technology
Lamborghini possesses
many years of experience with carbon-fiber reinforced materials. As
far back as 1983, it produced the first prototype CFRP chassis for
the Countach, with the first series production parts appearing in
1985. The current Lamborghini Murciélago is made largely from CFRP –
its body-in-white contains 93 kilograms of carbon-fiber materials.
The engine cover panel of the Gallardo Spyder is one of the largest
CFRP components with class A surface quality in the automotive
world.
The company is now working steadily to expand its worldwide leading
position. The new Advanced Composites Research Center (ACRC) at the
company headquarter in Sant’Agata Bolognese is working on innovative
construction and production methods for carbon-fiber elements in
automobile design.
The Advanced Composite Research Center in Sant’Agata Bolognese
secures leading-edge research on innovative materials and production
methods for carbon fiber elements for small production volumes.
Here, over 30 experts develop vehicle components of all shapes and
sizes. They build prototypes and the associated production tools
while developing optimized production technologies. Sophisticated
systems largely developed in-house allow extremely high precision
levels as engineers simulate manufacturing processes as well as
carry out crash tests on complex carbon-fiber structures. Thanks to
the extensively patented “RTM Lambo” process, Lamborghini can use
minimal pressure and relatively low temperatures to manufacture
carbon-fiber components to the highest levels of quality, precision
and surface finish, from small parts to complex vehicle structures.
Further benefits include higher process speeds, lower costs, and
extremely light tooling.
The Lamborghini Advanced Composite Structures Laboratory (ACSL) at
the University of Washington uses experimental tests to define the
mechanical behavior of the different materials and technologies
using methodology from the aviation industry. The team of research
engineers in Seattle works with very specific instruments and
methods in close cooperation with the R&D headquarters and the ACRC
in Sant’Agata Bolognese.
