Peugeot Unveils New Technology on BB1 Concept

As Peugeot celebrates 120 years of automotive innovation, the company has used the 2009 Frankfurt Motor Show to unveil the BB1 Concept.

The urban-focused vehicle debuts a number of innovative Peugeot technologies designed to address the real world mobility requirements of the residents of future cities.

Capable of seating four people in a vehicle just 2.5 metres long, the BB1 concept car is a full electric vehicle that reinvents many aspects of the automobile.

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 manoeuverable (3.5m turning circle).

To achieve all this, Peugeot faced a 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 configuration 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).

Rear occupant space is helped with the implementation of a double bubble roof, as seen on the RCZ sports car.

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 “smartphone” functionalities: telephone, navigation, Internet access, radio, MP3... simply by connecting your device to the USB jack, or the 12V socket.

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.

The BB1 is fitted with electric motors in the rear wheels, designed in association with Michelin, and maximising 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.

Its characteristics give it the best possible response at start-up (0 to 30 km/h in 2.8 seconds) and excellent in-gear acceleration (30-60 km/h in 4 seconds), ensuring the driving enjoyment and safety that are hallmarks of Peugeot.

The lithium-ion batteries provide immediate power and 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 assists vehicle stability, especially during braking.

The BB1 is 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 offering 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, and ensuring optimal weight distribution.

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

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 filters and activated carbon.

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.

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.

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 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.
