PRESS RELEASE

The 207 EPURE

The beat of an alternative heart.

In 1998, the concept-car 20. was presented for the first time. The enthusiasm it aroused among the public fuelled the development of a new mass-produced car design: the Coupe / Cabriolet. Combining vision and realism, the 206 CC - the first vehicle in the small car segment to have a metal electric folding roof - met with well-documented success and was then followed in the higher segment of the Peugeot range by the 307 CC. With the launch of the 207 hatchback, Peugeotfs designers naturally considered including a CC version in the new range, and applying all their expertise in the field of vehicles styled for pleasure. With the 207 EPURE concept car, the Marque for the one part lifts the veil on a tangible future product. However, its personality is twofold: in addition to twin coupe / cabriolet adaptability, this styling blueprint also conceals an example of future fuel cell technology for a more distant future... The experimental power train that equips the 207 EPURE includes the latest advances of the PSA Peugeot Citroen group in this area, without any adverse affect on the vehiclefs functional and stylistic features. The spirit of freedom inherent in this design is therefore closely bound up with the carfs method of propulsion: the ensuing benefi ts - zero emissions, silent operation - which does much to enhance the pleasure of driving the car as a cabriolet. Both driver and car are then truly at one with their environment. Pleasure and ecology are united.

Style

Exterior

The pearl white livery highlights the purity of the concept carfs lines while symbolising the ecological credentials of the technology that powers it. The familiar, elegant and expressive design of the front of the 207 EPURE, is strengthened by its bold and fl owing contours. From the side, the high waistline at the rear creates an effect which, combined with the angle of the front windscreen and the arch of the closed roof, enhances the carfs dynamic presence by creating a sense of movement, even when it is stood still. The sculpting of the lower side panels adds further to the overall personality of the vehicle. Its special Pitlane alloy wheels strengthen the impression of a vehicle with superb road holding. Chrome detailing circumvents the perimeter of the passenger compartment and includes a bold styling feature, located on top of the boot lid, helping to enhance the fl uidity of the design of the rear of the car. Extending from the boot lid, the rear spoiler, with its pronounced integrated shape, blends harmoniously into the rear diode-effect lights. Meticulous surface finishes, eloquent style lines and perfectly balanced proportions give the vehicle the natural equilibrium, elegance and dynamism sought after by its designers, whether it is a coupe or a cabriolet.

Interor

The interior expands on the theme of purity expressed by the exterior. The fascia panel of the 207 EPURE, originally smooth and fl uid, is covered entirely with white leather, as is most of the passenger compartment: the detailing, the trim on all four seats, and even the controls under the steering wheel. The white dials of the instrument panel and the chrome trims strengthen the modern and technological feel of the interior. Touches of absinthe green, inspired by the vehiclefs fl oor colour, are subtly interspersed throughout the passenger compartment, particularly in the form of discreet beads on the fascia panel, the door panels, the rear of the front seats and the head restraints. This colour also appears in the perforations of the seat leather, like little bubbles of oxygen, echoing the vehiclefs ecological method of propulsion. This harmony between white and mineral tones further accentuates the sensation of freedom, relaxation and energy that emanates from the car. From a functional point of view, the instrument panel incorporates all necessary information for monitoring the charge level of the battery and the quantity of on-board hydrogen, while the colour display in the centre console displays the fl ow of power between the electric motor, the battery and the fuel cell.

Fuel cell

The strategy of PSA Peugeot Citroen

In a global context where the need to consume less energy and reduce CO2 emissions is paramount, the PSA Peugeot Citroen group is continuing its technological research into clean and economical vehicles. In addition to work on improving the effi ciency of internal combustion engines, particularly with HDi engines, the ability of the Groupfs engines to run on fuels that incorporate biofuels, the invention of the DPFS (diesel particulate fi lter system) and research into HDi Hybrids, PSA Peugeot Citroen is also studying future technologies.

For example, the hydrogen fuel cell could represent a high-potential energy source for the future.

The advantages of the fuel cell for the environment are many:

* it provides an alternative to fossil fuels

* it helps to reduce CO2 emissions and therefore to control the greenhouse effect,

* it improves the quality of life in town, thanks to the silent operation of vehicles that use an electric motor and the elimination of local emissions.

This technology, however, still has to overcome a number of technical and economic challenges before large-scale production can be envisaged. PSA Peugeot Citroen has therefore adopted a research strategy which aims to explore different solutions. This work has therefore given rise to the production of a succession of demonstrators.

Taxi PAC

The Peugeot Taxi PAC is a sort of 21st century London taxi. In this demonstrator, hydrogen is stored in the form of compressed gas (300 bar) in a racks of removable cylinders. Refi lls (replacement of an empty cylinder rack) can therefore be carried out quickly, which corresponds perfectly to the targeted use: as an urban fl eet vehicle.

H2O

The Peugeot H2O is the place where a childfs dreams meet those of an engineer: behind the theme of a fi re engine, it aims to provide a solution to the problem of storing hydrogen by producing it on demand on the vehicle itself, by means of an aqueous solution of sodium borohydride.

The Quark

The Peugeot Quark, a handsome and futuristic 2-seater quad, illustrates numerous innovations through its compact size. For example, the fuel cell is cooled by air and hydrogen is stored in a single plug & drive cylinder at a pressure of 700 bar (which increases the vehiclefs range compared to a pressure of 350 bar). Instead of a single electric motor, the Quark has four electric motors located in each of its wheels. Continuing this research, the Group, in partnership with the AEC (Atomic Energy Commission), is working currently on a new design of compact fuel cell that will make it possible to improve electrical power output, energy effi ciency and packaging: the GENEPAC (GENerateur Electrique a Pile A Combustible), or fuel cell electricity generator. This technology is present today in the 207 EPURE .

Fuel cell technology

Operating principle of the fuel cell electric propulsion system To operate, a fuel cell needs hydrogen and oxygen. Oxygen is drawn from the air, while hydrogen is stored on the vehicle. The combining of these two elements creates an electrochemical reaction that causes a displacement of electrons and protons which simultaneously produces heat, water, and above all electricity. The 207 EPURE , like previous demonstrators, uses the fuel cell as a source of on-board electrical energy (increasing the maximum distance the vehicle can travel - range extender). It powers the electric motor (propulsion system) directly as well as helping to recharge the batteries.

Technological content of the 207 EPURE : the GENEPAC 20

For the first time on a demonstrator, the 207 EPURE uses a GENEPAC fuel cell. Combining simplicity and modularity, this French designed cell has been designed to be compact in installation and effi cient in use. The principle of this new cell, featuring PEMFC (Proton Exchange Membrane Fuel Cell) technology, is based on the use of thin, stamped stainless-steel plates, which reduce the cost

and volume of the cell compared to traditional plates. This system also allows for simple gauging of the cellfs power. For example, the cell used on this demonstrator, called the GENEPAC 20, is a 20 kW version of the GENEPAC system. The, GENEPAC 20 consists of two modules each with a stack of thin plates and an assembly of electrode membranes. This fuel cell system therefore offers a level of effi ciency in excess of 50 % versus 25 to 30 % for an internal combustion engine. Five cylinders containing 3 kg of hydrogen compressed to 700 bar provides the electric motor and the lithium-Ion battery with as much extra power and range as possible. They are located at the bottom of the vehiclefs boot, which frees up the two rear seats, does not affect the operation of the retractable roof mechanism and leaves part of the boot available for use in the coupe position. Use of an electric motor allows the 207 EPURE to consume energy only when in motion and to save energy during phases of deceleration. It also makes this demonstrator silent, an important quality for a vehicle driven in town and highly benefi cial during use as a cabriolet. The PAC technologies give the 207 EPURE demonstrator a considerable range (around 350 km) while offering a pleasing level of performance with a maximum speed of 130 km/h.

Helping to preserve pure air by emitting only water, this 207 EPURE of the future is therefore well suited to urban and semi-urban use... For pure sensations, original and purposeful!

PEUGEOT 207 EPURE

Aperitivo del 207 CC

Este prototipo anticipa las líneas del próximo Peugeot 207 CC. Sin embargo, el Epure se caracteriza además por estar propulsado por un motor éléctrico alimentado por oxígeno e hidrógeno. Por tanto, el Epure se suma a otros proyectos de Peugeot, que también han incluido la pila de combustible como es el caso del Taxi PAC, el H2O y el Quark.

MADRID.-Peugeot presentará en el Salón de París el prototipo 207 Epure, un coche que, además ser impulsado por una pila de combustible, servirá de base para el próximo Coupé Cabriolet, que la marca francesa tiene previsto comercializar en primavera.

Que el Peugeot 206 CC fue todo un éxito, nadie tiene duda. La firma del león rompió moldes en 1998 cuando inició la comercialización de este modelo. La llegada del pequeño cabrio supuso la democratización de los descapotables, es decir el acceso a este tipo de vehículos para personas de todas las clases. Para argumentar esta afirmación, basta señalar que sólo en España, Peugeot ha comercializado cerca de 19.000 unidades del 206 CC.

Ahora, tras la llegada del nuevo 207, de todos es sabido que la marca francesa relanzaría aquellas versiones que han gozado de notable éxito. Y el descapotable no iba a ser menos. Sin embargo, y hasta que se presente el modelo definitivo de producción, Peugeot presentará en el Salón de París un prototipo que adelanta las líneas del próximo 207 CC.

Hablamos del Epure, que se caracteriza por ser un descapotable de techo rígido y cuatro plazas. En lo que se refiere a la versión de producción, el nuevo 207 Coupé Cabrio, se trata de un diseño de la propia marca sin la colaboración de carroceros externos (en el 206 colaboró Pininfarina en la elaboración del techo metálico plegable).

Tan sólo la empresa alemana Edcha suministra los mecanismo de plegado y apertura del techo. El coche mantiene las dimensiones de la berlina y el concepto de dos plazas más dos asientos de reducidas dimensiones en la parte trasera. La apertura y cierre del techo es completamente automática.

Pero volviendo por el momento al prototipo, según afirma Peugeot este nuevo modelo destaca por su dinamismo, tanto cuando está presente el techo rígido plegable como cuando no lo hace. A ello ayuda la inclinación del parabrisas y la prolongación de esta línea hasta el final del vehículo.

El resto de los elementos que conforman el diseño, incluso el color blanco escogido por la marca, pretenden resaltar, como el propio nombre indica, una sensación de pureza.

Por su parte, en el interior también se quiere destacar esa cualidad. El tablero de instrumentos está revestido de cuero blanco, al igual que sucede en la mayor parte del vehículo como son los asientos y los mandos bajo el volante, que es rematado por toques verdes repartidos por el habitáculo.

Mientras, en el cuadro de mandos combina las indicaciones del nivel de carga de la batería, y de la cantidad de hidrógeno presente, con una pantalla a color situada en la consola que permite la visualización de los flujos de potencia entre el motor eléctrico, la batería y la pila de combustible.

Y es que esta es otra de las características principales del 207 Epure. En la búsqueda de soluciones al ahorro de energía y la reducción en la emisión de gases contaminantes, Peugeot ha instalado en este prototipo un motor eléctrico alimentado por hídrógeno.

Para propulsar el coche este motor requiere de oxígeno y de hidrógeno. Lo primero es extraido del aire, mientras que lo segundo está almacenado a bordo de cinco bombonas situadas al fondo del maletero que contienen en total tres kilogramos de hidrógeno comprimido a 700 bares.

La asociación del oxígeno y del hidrógeno desemboca en una reacción electroquímica que provoca el desplazamiento de electrones y protones, surtiendo así al vehículo de calor, agua y sobre todo electricidad.

Esta electricidad generada alimentará el motor eléctrico, que sólo consumirá energía cuando está en movimiento y se recargará cuando se encuentra en fase de desaceleración.

Así, el motor eléctrico logrará una potencia de 70 Kw -alrededor de 95 caballos- y un par máximo de 180 Nm. Esta cifra de potencia se consigue tras combinar la batería de tipo Lio-Ion y la pila de combustible 'Genepac 20' de 50 y 20 kw respectivamente.

Hola de nuevo, despues de mis merecidas vacaciones, me reincorporo al mundo 307

Creo que con respecto al 206 CC mejora en cuanto a la zona trasera, suavizando la continuidad entre el techo y maletero. ¿Mejorarian la utilizacion de los asientos traseros, o siguen siendo un adorno?

En cuanto al Frontal, se parece mas al 307, mas estilizado, un ejemplo de lo que deberian haber hecho con el 307 :wink:
