2010 Peugeot EX1 Concept

(continued from above)

The pure styling of this two-seater roadster is in keeping with its mechanical design, like a kind of "exoskeleton" highlighting the light-weight nature that guided the vehicle's creation.

The design of the body incorporates Peugeot's new stylistic design codes, first seen on the SR1 concept car earlier this year, with its "floating" front grille and flowing contours. Polished aluminum components adorn the door surrounds in a reference to the RCZ and BB1.

Architecture, Structure and Suspension

Far from being a "classic" roadster, the EX1 concept car is based on an architecture shaped like a "water droplet", with a rear section built around two closely set rear wheels.

Based on the experience gained from creating the 1996 Asphalte concept car and the two 20Cup models from 2005. The chosen architecture of the EX1 has enabled the size of the passenger compartment to be reduced for optimal weight distribution and ensure that there is no extra weight at all in the overhangs.

The suspension employs a number of technical solutions that ensure road holding of a very high level. The front suspension consists of a drop link double wishbone arrangement. The rear suspension comprises of a single "swinging arm" linked to a centrally mounted shock absorber which is connected via a rocker arm to provide a variable damping rate.

The monocoque body structure is manufactured from a carbon/honeycomb composite to optimize weight and rigidity. It also incorporates all of the mounting points for the car's mechanical components.

Finally, the dimensions of the car contribute to overall efficiency, a lowering of the centre of gravity and improved aerodynamics.
