Peugeot EX1 Concept 2010
Peugeot is launching the Concept EX1, an electric roadster project intended to break some FIA records, at the time the Company is celebrating its 200 years and at the moment of the commercial launching of the Peugeot Ion electric car. The Peugeot EX1 Concept is also a styling exercise that provides some clues of the shape of future production models. Peugeot wants to demonstrate the electric propulsion can provide fun. The Peugeot EX1 concept has already broken several world records for acceleration from a standing start. It owes its performance to its streamlined aerodynamics, its ultra light structure and its two 125 kW electric motors providing a cumulative maximum power of 250 kW (340 hp) as well as four-wheel drive. Architecture, structure and suspension at the service of maximum efficiency. 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 (see images 20,21,22,23 and wallpapers below) , 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. The front suspension consists of a drop link double wishbone arrangement. The rear suspension consists 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 carbon/honeycomb composite to optimize weight and rigidity. It also incorporates all the mounting points for the car's mechanical components. The dimensions of the car also contribute to overall efficiency, a low centre of gravity and improved aerodynamics. The overall height is 0,90 m while the width is 1,77 m and the length 3,54 m. On the Peugeot EX1 Concept car, two electric motors are used, one on each axle, providing a total peak output of 250 kW (340 hp) and an immediately available constant maximum torque of 240 Nm at the front and rear. This allow to drive with no gear change.
The driver and passenger climb into the passenger compartment through a reverse opening door, giving access to the two bucket seats. The on-board instrumentation comprises an instrument panel screens for each occupant showing in particular the vehicle's instantaneous performance. The material for the instrument panel is pure metal and embossed leather. The driver operates the vehicle with two control handles. The electric energy is stored in 30 kWh Lithium-ion batteries that allows for a quoted 450 km range. The overall weight of the car is a mere 750 kg. Acceleration from 0 to 100 kph (62 mph) is announced for 3,58 seconds while top speed of 260 kph is reached in a quoted 6,6 seconds. Texte Paul Damiens - Photos by Peugeot.
