Peugeot’s new concept to demonstrate possibilities of electric cars

    French vehicle producer Peugeot’s latest concept car is a visually striking, eager-to-speed, two-seater electric roadster, shaped like a water droplet.

    The EX1’s weight (750 kg), weight distribution and aerodynamics, the torque and power of its two electric motors and its high-output lithium-ion battery makes it possible for the car to achieve lightning acceleration.

    The concept EX1

    The EX1 has a maximum speed of 260 km/h, and it can reach 100 km/h from a standing start in 3,58 seconds.

    Its electric motors provide the car with a cumulative maximum power of 250 kW.

    As the preparations for the commercial launch by the end of the year of the Peugeot iOn electric vehicle near completion, Peugeot says it aims to use the EX1 to demonstrate the possibilities of electric power. 

    Far from being a “classic” roadster, the droplet-like EX1 concept car has a rear section built around two closely set rear wheels. This is 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 in the overhangs.

    The suspension employs a number of technical solutions that ensure road holding at a 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 by a rocker arm to provide a variable damping rate.

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

    Finally, the dimensions of the car (0,90 m high, with a width of 1,77 m) contribute to overall efficiency, a lowering of the centre of gravity and improved aerodynamics.

    Two lithium-ion electric motors are used on the EX1 concept car, one on each axle, each with a peak output of 125 kW, and an immediately available constant maximum torque of 240 Nm at the front and rear. 

    This mechanical architecture allows not only for the optimisation of weight distribution, but also enables four-wheel drive. 

    The driver and passenger climb into the passenger compartment through a reverse-opening door, giving access to two sports bucket seats. 

    The driver, seated at floor level in a driving position that enhances the sense of excitement (legs outstretched), drives the vehicle with two control handles, providing an experience similar to that of an aircraft pilot or a video game.

    Apart from the harnesses inside the car, the occupants are also protected by the height of the carbon passenger cell, which has sufficient overhead clearance to include a roll-over protection bar. Similarly, the wind deflector allows the car to be driven on a daily basis without a helmet.
