Renault Fluence Z.E. Concept

Production Cars 18 Sep 2009

The Fluence Z.E. Concept is Renault’s vision of an all-electric family car for the next future. The exterior is characterized by high-tech graphic elements, while the interior features flowing forms. It offers a range of 160 km and previews a production model.

Debuting at the 2009 Frankfurt Motor Show, the Renault Fluence Z.E. Concept is an all-electric car “aimed at the single-car family father who would use the car every day to go to the office, but who would also want to take his wife and children to the country at the weekend.”

Therefore, the car needs to serve to an extent as a status symbol, but it must also provide enough interior space to function as a comfortable family car.

The range is up to 160km, and the battery can be charged using one of three methods: a standard charge (between four and eight hours), a quick charge (20 minutes) or an immediate solution (three minutes) which takes the form of the exclusive ‘Quickdrop’ rapid battery exchange system.

Design

The styling cues of Fluence Z.E. Concept combine the design language of motoring pleasure with the visual signature of Renault’s range of electric vehicles.

Fluence Z.E. Concept possesses dynamic lines, highlighted by a fluid character line which sweeps from the headlights to the rear shoulders.

It is 4,820mm long, has a wide track of 1,672 mm, is well- proportioned and expresses a premium look.

Its identity as an electric vehicle is expressed through the graphic treatment of the cooling ducts, the fins of which are reminiscent of heat transfer surfaces, and this theme is echoed in different ways in the design of the headlights and motor cover.

The photovoltaic cells located on the panoramic roof, dashboard and rear parcel shelf form a geometric grid pattern which has been carried over to the grille and seat upholstery.

Styling cues share with Renault’s ‘family’ of electric vehicles include the Atmosphere Blue body colour, the specific luminous blue signature which features in the curved lower part of the body
sides; the use of LEDs at the front and rear; the design of its headlights, – the recess behind the logo on the hood.

The headlights convey the same impression of softness suggested by the vehicle’s overall lines and colour.

Beneath the ‘eyelids’ formed by the indicators, the beams of the main headlights are precise and piercing, with the light focused into a single beam by means of a system of prisms.

The vehicle’s status-enhancing credentials are emphasised by chrome trimming for the belt-line and grille, as well as by its 21-inch wheels.

Blue polycarbonate hubcaps seem to slot into the aluminium wheels to create a spiral form which channels the airflow and improves aerodynamic performance.

Interior Design

Fluence Z.E. Concept’s warmly welcoming and refined interior is based on a combination of flowing forms, the use of soft, supple materials and a mottled ambience. Passengers are comfortably seated in four enveloping seats robed in light leather upholstery.

The feet rest on a light blue translucent gel mat, while the brake and accelerator pedals, too, are covered in gel for a greater sense of comfort.

When the doors open, the courtesy lighting recalls the luminous blue signature of Renault’s electric vehicle range.

In the dahsboard, a TFT (Thin Film Transistor) touchscreen displays multimedia information and essential journey-related information such as the navigation function and the location of the nearest ‘Quickdrop’ station. The display also provides data specific to electric vehicles, such as range optimization information, for example.

The centre console incorporates two floating armrests and forms a fluid, rearward-flowing arc. At the front, the integrated central front armrest includes the stop/start button, the air-conditioning and volume controls, as well as the new touchscreen Samsung Jet phone.

This phone comes with a hands-free function, and also enables occupants to listen to music or enjoy a film on the screens which have been built into the front seatbacks.

The central rear armrest incorporates the climate
control and volume controls, plus another Samsung Jet telephone and two remote controls for the two screens.

Significant care has also gone into the design of the door panels: the door handles echo the rounded form of the centre console and the electric window controls are flush with the surface, while the viewing screen for the rear-view cameras is integrated discreetly yet effectively.

The photovoltaic cells meet part of the car’s energy requirements with a view to complementing
the power supplied by the battery, – the headlights use high-performance electroluminescent diodes which deliver an excellent
trade-off between efficiency and energy consumption, – the triple-zone climate control system allows occupants to achieve just the right settings for the two seats at the front and at the rear.

The air vents also feature a dynamic lighting code, with blue representing the passage of cold air and red representing warm air, – the car’s aerodynamics have been meticulously honed to minimize drag, including streamlined rear-view mirrors with integrated rearward facing cameras, a completely enclosed underside
incorporating a diffuser at the rear, and spiral-form wheel rims, – Fluence Z.E. Concept runs on low rolling resistance Michelin tyres.

Fluence Z.E. Concept is powered exclusively by an electric motor located near the front axle, in conjunction with a lithium-ion battery positioned between the rear seats and the boot

Renault’s designers and engineers worked closely together to develop a safe, practical vehicle capable of accommodating a large enough battery to ensure good range (160km), while also providing sufficient carrying capacity to cater for the requirements of an active family (327dm3).
