ITALDESIGN GIUGIARO QUARANTA CONCEPT POWERED BY TOYOTA HYBRID SYNERGY DRIVE
Uncompromising innovation in Giugiaro tradition
An "extreme", clean-technology project embodying 40 years of styling
research and engineering celebrated by Italdesign Giugiaro in Geneva
The "Quaranta" project is a concept car designed to celebrate Italdesign
Giugiaro's forty years of business in styling and technological research at
the service of the automotive sector. The Quaranta, world-premiered at the
2008 Geneva International Motor Show, is a synthesis of Italdesign
Giugiaro's unmatched experience of automotive design: from city cars to
super sports-cars, from MPVs to medium-engined saloons up to and including
luxury flagships and environment-friendly SUV, not to mention light/heavy
duty commercial vehicles, in complete cooperation with leading manufacturers
all over the world.
The Quaranta is an "extreme" product, an environment-friendly, 4WD super
sports-car which incorporates a series of innovative aspects: its styling,
but also its drive technology, which combines a hybrid engine with solar
energy, and its internal layout which, despite its mid-mounted rear engine,
can accommodate three adults and a child, also providing a generous luggage
compartment.
The idea which inspired the Quaranta project is that of the first
single-volume concept car with central engine and drive. The original
reference is to the 1968 Bizzarrini Manta which, at that time, represented a
major breakthrough in styling, now adapted to state-of-the-art technology
and enriched with Italdesign Giugiaro's forty years experience of research.
The style of the future
Despite its flat, highly compact shape, the Quaranta features a
single-volume shape characterized by a continuous body line stretching from
its clipped nose to the tail that exploits the almost horizontal rake of the
windscreen.
Access to the cabin is "step-in" via an upper door incorporating the side
ones. At the touch of an electric on/off button, the door opens upward in a
downwind direction, regulated by proximity sensors. The door is hinged to
the hood pillar and is aligned with a second upper rear door, for access to
the engine compartment and boot.
The roof houses the array of solar panels, necessary to power the electric
battery, in the space between the two doors. Along with the other solar
panels positioned on the front end, these create a central opaque strip, a
distinctive signature of the model, thanks to the interplay of light with
the bright paint of the bodywork. The solar panels can generate a power of
up to 250 W, sufficient for the functioning of the cockpit conditioning
system and for recharging the electric battery.
The styling of the Quaranta prototype is further enhanced by the attention
dedicated to surface aerodynamics, designed to ensure maximum possible
efficiency and penetration, also by using sharp edges on the rear. This can
also be noted in the front end of the vehicle where the radiator grille has
been eliminated and replaced by two side air inlets, positioned above the
lighting clusters, which perform the delicate function of front stabilizers.
The rear of the vehicle has also been conceived to improve overall
aerodynamic performance: an attentively-molded spoiler, with a perfectly
square-edged cut and a very technical design, has the scope of supporting
the lower wing, modeled according to latest generation F1 styling, that
makes up for the absence of the traditional upper stabilizer.
Styling research aimed at top aerodynamic performance is also reflected on
the sides, characterized by extremely generous glazing stretching from the
front fender to the tail and in which the air vents are housed, located
after the doors but also along the sill, in which the water cooling ducts
are inserted. The most innovative feature of the side profile is certainly
the contour line, between the door-windows and the sill, which is "negative"
in the shoulder section, a particular, absolutely innovative feature for
super sports-cars.
Interiors: technology for safety and comfort
Inside, the most striking innovation can be found in the multi-control
steering wheel which reflects an idea already incorporated in the 1980
Medusa, a prototype developed by Italdesign and on display at its stand in
Geneva: all vehicle driving and control functions are concentrated on the
spokes, where the stalks have been eliminated and replaced with keys. This
guarantees easier control by the driver, in a central position which can be
obtained due to the absence of the gearbox-transmission block tunnel. This
is possible thanks to the electric four-wheel drive system which eliminates
any obstacles on the floor pan, making it completely flat. The
generously-scaled central space of the cockpit can accommodate two adults
and a child, behind the driver. The dashboard has been conceived with a
sporting, modern look, with clean-cut details matching the style of the
exterior, and equipped with a vast array of instruments. These are organized
on two levels: the screens of the side and rear TV cameras are positioned on
the upper level, with particular attention to the left-hand view mirror,
useful when overtaking; the lower level is dedicated to the management of
the vehicle. The drive-panel also includes a visor for X-ray sensors for
night driving. The dark-colored leather and alcantara upholstery reflects
the most refined Italian taste.
The lighting clusters are extremely modern: the low-beam lights are based on
led technology, while the full-beam are of the Bi-xenon type. The direction
indicators, the tail and rear stop lights are of the full led type, inserted
in a single box but differentiated according to color, assembled and adapted
by hand at Italdesign Giugiaro.
Last but not least, the Quaranta features 9 ½ by 20" alloy wheels, without
hub caps for improved styling and aerodynamics, and four Vredestein tires as
standard, which differ only in shoulder height: 275/35/R20 front and
275/40/R20 rear. The dimensions are certainly tight for a super sports-car
but suitable for a 4WD car.
Mold-breaking mechanicals
The structure of the prototype is made up of the carbon monocoque frame onto
which aluminum and special steel parts are assembled, while the windscreen
and roof are made of stratified glass with UVA filter. The Quaranta is fit
with electronic four-wheel drive, divided in a small electric motor on the
fore-carriage and the thermal engine/electric engine system located in a
central rear position. This particular structure, which has seen Toyota's
involvement in the electronic control management, has made it possible to
develop the vehicle on a 2620-mm wheelbase, ideal for a mid-engined car.
The batteries which assist the electric motors are located between the
engine compartment and the cockpit and are powered directly by the solar
panels. The Quaranta features a double fuel-tank, integrated in the
supporting frame, with a total capacity of 60 liters, giving a mileage of up
to 1000 km.
Dynamic asset is variable in two ride height positions: sporting and raised.
Maximum ground clearance is 230 mm, an absolute record which means that the
super sports-car can take any type of terrain in its stride. The main
technical aspect that distinguishes the mechanical design of the Quaranta is
the weight balance and in particular the "weight centering": all the
mechanical weight of the vehicle is contained between the two axles,
including the mufflers which are positioned in front of the rear wheels.
Only the radiator and a large overhanging luggage compartment, able to
accommodate two golf-bags, remain outside.
The front suspensions also represent a breakthrough: designed according to
F1 cars, they are equipped with a central mono-shock echoing an idea already
presented by Italdesign – Giugiaro on the 2004 Toyota Volta and on the 1997
Alfa Romeo Scighera. The linkage mechanism of the levers guarantees
exceptional stability in any type of situation, simulating a "multilink"
mechanism. The links have been designed and engineered entirely by
ITALDESIGN GIUGUIARO: the "ovalized" down tubes are made of special steel
and the uprights of Ergal.
The entire Quaranta project is an idea of Italdesign Giugiaro, constructed
in accordance with the classical formula of the package of services
furnished to automotive manufacturers.
Quaranta confirms the classic Italdesign – Giugiaro versatile service
formula for car manufacturers. The competence and capability of designing a
new car model considering style development, frame development, safety and
ergonomics analyses and mechanics development, starting only from a given
functioning engine.
The chassis, bodywork and layout of the Quaranta prototype have been
designed by the Engineering Division of Italdesign Giugiaro, while the
mechanicals and electronics have been developed in cooperation with Toyota.
The vehicle was entirely built at the Moncalieri facilities.
The Italdesign Giugiaro construction process
The Italdesign Giugiaro construction and prototyping process, tried and
tested during forty years of activity in the automotive sector but also
extended to industrial design, preserves certain characteristics of
technical specialization and production quality of unequalled value.
- Construction of a prototype involves various completely independent phases
that can also be carried out with a modular approach. Starting from
hand-made drawings, the next step is Styling Research and definitive
development of the master models, using state-of-the-art CAD technologies.
In parallel, the phases of technical design of the prototype
interior, or even of only some parts, can be integrated with style
development, producing a unique technical result. This is the most complete,
professional process that Italdesign can offer its clients. Following
consolidation of the styling-engineering project, a full-scale mockup is
built. The mock-up gives the possibility of physically evaluating
modifications and integrations and represents the basis for the subsequent
construction of the final prototype. Italdesign can also carry out various
technical tests, including the model crash-test;
The prototyping phase, a mainly hand-crafted process with the aid of
forefront automated systems, includes preparation of the assembly jigs
(so-called negatives), usually constructed by hand in the workshop, and
hitting models milled according to the style master models, useful for
beating the sheets of aluminum or stratified carbon;
Work on the interior is necessary in order to prepare the seats, facial,
door panels and all the other elements inserted in the cabin of the vehicle.
Lined fiberglass-reinforced parts are always constructed at Italdesign, and
also the upholstery, available in any type of material or shape required;
The above phases are followed by construction of the mechanical and
structural parts of the prototype, preparation of the tooling and uprights
necessary for the construction phase and beating of the parts, assembly of
the structure, of the interior and accessories and lastly painting. In the
case of the Quaranta prototype, the door was designed and constructed
entirely at Italdesign using a temporary piston tubular structure,
subsequently reproduced and fastened to the chassis.
Cooperation between Toyota-Italdesign Giugiaro
Cooperation between Italdesign Giugiaro and Toyota Group started with the
supply of the high performance hybrid engine fit on the Volta prototype,
displayed for the first time at the 2004 Geneva Show.
For the Quaranta, Toyota furnished Italdesign Giugiaro with a derivative of
the latest available hybrid system, Toyota Hybrid Synergy Drive technology.
The innovative aspect of this engine lies in the ability of the electronic
control system to regulate the power distributed by the electric motors to
the wheels, making the clutch-gearbox-transmission block superfluous.
The Toyota Hybrid Synergy Drive system guarantees power, acceleration and
top performance still keeping high mileage, reduced emissions and extremely
silent operation. The compact battery makes it possible to store the energy
produced in the braking or deceleration phase instead of dispersing this as
heat.
The electric motor is complementary to the thermal engine but can also
operate independently, activated by the electronic traction control unit
where ideal conditions exist.
The Toyota Hybrid Synergy Drive system consists of a V6 3.3 liter gasoline
engine and of two electric motors that operate in synergy, delivering a high
power output, comparable to that of an 8-cylinder engine, but with fuel
consumption and emissions lower than those of a 4 cylinder engine. To
improve efficiency and handling, the intelligent E-Four system automatically
activates two- or four-wheel drive, taking advantage of the increased
handling and stability of four-wheel drive in acceleration, cornering or
braking, and the reduced consumption and acoustic comfort of rear wheel
drive at normal cruising speed.
The Toyota Hybrid Synergy Drive system also includes the E-CVT
Electronic-Continuously Variable Transmission, an automatic planetary gear
transmission with ratios varying infinitely as speed changes.
The real innovation of the Quaranta prototype is reflected in the mid-ship
positioning of a hybrid engine on a super sports-car that guarantees high
performance with reduced consumption and low emissions.
