PEUGEOT BB1 : Creativity in pursuit of the freedom of movement

Peugeot BB1 Concept

With its BB1 concept car, Peugeot has fearlessly pushed back the conventions and boundaries of automobile manufacturing to bring a totally original response to the current and future needs of urban mobility.

Capable of seating four people in a vehicle just 2.5 metres long, the BB1 concept car is a full electric vehicle that reinvents the automobile in every way: architecture, style, interior design, drive, connectivity – while all the time respecting the environment.

At the forefront are the values of liberty, optimism - even "altruism". The BB1 concept car is the promise of a new driving experience.

A totally original idea

The BB1 brief was to tackle all issues of the modern world faced by people on a daily basis in order to offer maximum versatility, a compact size; be dynamic and manoeuvrable (3.5m turning circle).

To achieve all this, the Peugeot teams faced a real challenge - never before seen in the history of the automobile: accommodating four people in a car 2.5m long.

This record use of interior space could potentially lead to a larger load capacity, even though its “compact” size gives it the ability to park in extremely tight spots - even perpendicular to the pavement.

To meet this challenge, the structure of the passenger compartment has drawn inspiration from two-wheeled vehicles in terms of ergonomics: the driver controls the
vehicle by adopting a new driving position - more vertical than is usual. This is mainly made possible through the absence of floor pedals. The rear passenger is seated in tandem behind the driver. On the right-hand side, front and rear passengers adopt the same position. It is thanks to this original confi guration for a four-wheel vehicle that the BB1 has such a totally original design.

Access to the vehicle is through the inverted door opening mechanism, while boot access is through a tail board and a tailgate. The interior can be transformed as required to offer a load volume of 160 litres (with four occupants), rising to 855 litres (with just one person in the car).

A stylish break with the past

The style of the vehicle highlights the interior space and the driving ergonomics. With its sweeping styling lines at the front, large glazed area, low doors (for the passenger compartment ventilation system) and very clear wheel arch space.

The car also represents a break with the past through its exterior styling in relation to the automobiles we have seen to date. Robust and protective, the quality and technology shine through in every detail, such as the “full LED” front headlights and rear view cameras.

The double bubble roof, as in the RCZ, helps with the rear space of the vehicle.

User-friendly connectivity

As well as the openness and brightness brought by the large windows, the BB1 presents an extensive set of interactive technologies. The colour display and the vehicle’s audio system provide an ideal setting for your “smartphone” functionalities: telephone, navigation, Internet access, radio, MP3... Just connect your device to the USB jack, or the 12V socket if necessary.

Universal and user-friendly, this system enables the BB1 to concentrate on essential services without multiple pieces of equipment, bringing extra safety to driving and saving considerable weight.

Similarly, the rear-view cameras remove the need for mirrors, optimising the width of the vehicle and improving its aerodynamics, while adding to the high-tech aspect of the interior.

Two original creative images have been produced for the BB1 concept by the artist Michel Serviteur. Portrayed around the driving position, they offer a new link with
time and speed. A clock brings the interior to life by linking a colour to each period of the day; time goes by to the rhythm of the light to enhance the feeling of wellbeing.

In addition, there is a graphic animation which could replace the speedometer, finding its equilibrium at a steady speed but which moves again when that speed is interrupted.

An environmentally efficient vehicle

...with a new electric motor

Creative - the BB1 leads the way with its electric drive system. It is fi tted with electric motors in the rear wheels, designed in association with Michelin. This original set-up maximises the interior space. It draws its inspiration from the world of the quad bike, with a maximum power output of 15 kW (20hp) - or 7.5 kW per motor. This provides the optimum power to weight ratio for the vehicle in its urban driving setting. Its characteristics give it the best possible response at start-up (0 to 30 kph in 2.8 seconds) and excellent in-gear acceleration (30-60 kph in 4 seconds), ensuring the driving enjoyment and safety that are the hallmark of Peugeot.

The lithium-ion batteries provide immediate power. They have a comfortable range of 120 km. Each of the two battery packs supplying energy to the two respective electric motors are fitted under the right and left rear seats, thereby avoiding any reduction in the interior space and the storage space. Furthermore, this location between the two front and rear wheels helps with the centring of the vehicle weight and benefits vehicle stability, especially during braking.

...with an innovative, lighter structure

Peugeot engineers have completely reinvented the way to design a vehicle. The BB1 is therefore based on a tubular chassis designed by Peugeot Motorcycles. It includes all normal vehicle dynamic systems: electric power steering, suspension (double-wishbone front and rear suspension), friction damper spring assemblies - granting the vehicle a level of road-holding to match the vehicle’s performance, its urban nature and driveability and safety levels worthy of the Peugeot Marque.

The body is made up of a very light carbon structure, designed to wrap around the passenger compartment, all of which enables potential future customisation and a
possibility of a variety of vehicle shapes...

Finally, the vehicle weight does not exceed 600 kg, including the batteries, enabling all its mechanical parts to be placed in their ideal position, ensuring optimal
weight distribution.

...with its altruistic concept

Thanks to its electric propulsion, the BB1 is an environmentally friendly vehicle par excellence and emits no loud noise outside the vehicle, and above all no pollutant emissions owing to the fact that it consumes no fossil fuels.

But this eco-responsibility isn’t limited to just driving. At a standstill, the passenger compartment ventilation keeps operating in daylight thanks to the solar panels placed on the roof of the vehicle. This enables two functions: pre-ventilation of the interior and the trapping of pollutants and ultra-fine dust particles (μm), due to the use of high-performance fi lters and activated carbon.

...with the use of new generation solar cells

The BB1’s solar panels use cutting-edge technology, designed in partnership with the Ocean Vital foundation. Flexible (enabling their usage on surfaces as complex as
the dual-bubble roof of the BB1), they provide a high yield of around 16% of energy captured (a much higher performance than current systems) to power some of the
vehicle systems.

The Ocean Vital Foundation, created by round-the-world navigator Raphaël Dinelli, works towards the development of new clean technologies, the aim of which is to preserve our natural resources and our environment. As part of the BB1 project, Peugeot and Ocean Vital have entered into an agreement to support research and development into new renewable energy technology and therefore encourage the development of research projects and the “green economy” in France.

The story continues...

The name “BB1” isn’t the only reference to Peugeot’s history and the “Baby Peugeot” models of 1905 and 1912...

This ultra-compact, lightweight electric vehicle concept is also something of a throwback to the Peugeot VLV. Three hundred and seventy seven of which were built between 1941 and 1945, meeting the then special needs of users throughout the Second World War. All this stands as proof that Peugeot has always been able to create and adapt its mobility offers to a particular time and need.
