Peugeot BB1 concept at Frankfurt Motor Show

At 2550mm long the unconventionally styled car is shares similar proportions to that of a smart fortwo but is capable of carrying four adults.

The near vertical windscreen allows maximum use of the small interior space while the raised roofline allows rear seat passengers greater headroom.

There's no word yet on the car's production value with the BB1, for now, remaining an exercise in engineering and design.
