2010 Paris Motor Show Preview: Peugeot EX1 Concept

Article by Christian Andrei, on September 21, 2010

Prior to the 2010 Paris Motor Show, Peugeot revealed today the EX1 Concept, a new 100% electric concept car which promises to show the new design directions of the French manufacturer. Celebrating Peugeot’s 200th anniversary, the new car is powered by two electric motors, capable to deliver a total output of 250 kW or 340 hp.

The all-wheel drive two-seater roadster incorporates Peugeot’s new stylistic design codes, which were first seen on the SR Concept, unveiled back in March at the 2010 Geneva Motor Show.

Furthermore, the car features polished aluminum components seen on the RCZ and BB1 Concept. The new EX1 Concept has a height of just 0.9 meters and a width of 1.77 m.

What is more interesting is found under the design, where the car features two electric motors, one on each axle, each delivering 125 kW (250 kW / 340 bhp in total) as well as a maximum torque of 240 Nm.

And because this car is just a design study, the passengers have to climb into the passenger compartment using a reverse-opening door. 

Peugeot EX1 Concept is technically a two-seater electric roadster that is stylistically and technologically futuristic. It is derived and inspired by the body of the SR1 concept car that was unveiled earlier this year – bearing new design codes like its floating front gear as well as floating contours.

Likewise, its polished aluminum components found on the door surrounds are inspired by the RCZ and BB1. This new two-seat roadster concept from Peugeot features a body that seems to be an "exoskeleton," which gives a strong impression of the EV's lightweight nature.

In designing this futuristic EV concept, Peugeot built on its experience gained from the 1996 Asphalte concept car and the two 20Cup models from 2005.

Underpinned by an architecture shaped like a "water droplet," the Peugeot EX1 Concept car features a rear section built around two closely set rear wheels.

This water droplet-shaped architecture has allowed Peugeot to reduce the size of the passenger compartment of the Peugeot EX1 Concept, thereby paving the way for optimal weight distribution while making sure that it would have no escess weight in the overhangs.

To ensure that the Peugeot EX1 Concept holds onto the road as much as possible, Peugeot made use of different suspension arrangements.

For instance, the front suspension features a drop link double wishbone arrangement while the rear suspension includes a single "swinging arm” connected to a centrally mounted shock absorber, which is in turned linked through a rocker arm for a variable damping rate.

Press Release

Peugeot EX1 Concept

100% electric Peugeot EX1 Concept car is a visually striking two-seater roadster with a futuristic styling and an original architecture, designed to offer intense driving sensations as a celebration of the Marque's 200th anniversary.

The Peugeot EX1 Concept has already broken several world records for acceleration from a standing start. It owes its stunning performance to its streamlined aerodynamics, its ultra-light structure and its two electric motors, which give the car a cumulative maximum power of 250 kW (340 bhp) and four-wheel drive.

As the preparations for the commercial launch of the iOn near completion, Peugeot demonstrates with the Peugeot EX1 Concept the exciting possibilities for electric power.

200 years of adventure

The powerful spirit of inventiveness is always present in Peugeot's design offices and helps create an unceasing flow of ideas. The most daring, interesting and exciting of these ideas sometimes come together, to give the body and soul to an extreme dream car.

With the desire to unveil a stunning creation to celebrate Peugeot's 200th anniversary, some of these exciting ideas quickly became associated with another ambition: that of highlighting the enormous possibilities offered by the use of electric power in the realm of creating new driving sensations. To this end, engineers and stylists explored the Marque's history to find the most radical technical solutions to use as a basis to produce a futuristic performance car dedicated entirely to creating new driving sensations yet at the same time presenting responsible environmental credentials. The original architecture is reminiscent of previous charismatic concept.

At a time when the electric motor once again becomes 100% real for Peugeot, with the i0n about to go on sale, the Peugeot EX1 Concept propels us into a new dimension of raw emotion.

Efficient styling

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 aluminium components adorn the door surrounds in a reference to the RCZ and BB1.

Architecture, structure and suspension. at the service of maximum efficiency Far from being a "classic" roadster, the Peugeot 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 Peugeot EX1 Concept 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 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.

Engines: PEUGEOT expertise in the field of electric power

The electric motor is a potential source of new driving sensations thanks to its exceptional acceleration capabilities, but also because it is silent in operation and makes the car very easy to drive (no need for a gearbox).

On the Peugeot EX1 Concept car, two electric motors are used, one on each axle, each with a peak output of 125 kW (250 kW / 340 bhp in total), and an immediately available constant maximum torque of 240 Nm at the front and rear.

This mechanical architecture allows not only the optimisation of weight distribution, but also four wheel drive. This reflects the positional benefits of HYbrid4 technology, available as standard on the 3008 from 2011, featuring an HDi FAP diesel engine at the front and an electric motor at the rear.

A futuristic and sophisticated passenger compartment

The driver and passenger climb into the passenger compartment through a reverse-opening door, giving access to the two sports bucket seats. This unusual arrangement instantly immerses the occupants in a futuristic and sophisticated environment, as does the on-board instrumentation (instrument panel screens for each occupant showing in particular the vehicle's instantaneous performance) and the chosen materials (e.g. "pure" metals and embossed leather).

The driver, seated at floor level in a driving position that helps 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. video game. As well as the presence of 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, perfectly integrated in terms of style, allows the car to be driven on a daily basis without a helmet.

An electric dream car designed to be a record beater

The Peugeot EX1 Concept car benefits from characteristics that give it a high enough level of performance not only to leave behind the city centre, the preferred territory of electric vehicles, but also to challenge acceleration records. Its lightness, weight distribution and aerodynamics, the torque and power of its two electric motors and its high-output lithium-ion battery are just some of the characteristics that make this a car capable of lightning acceleration: the latter can exceed 1G of gravitational force.

Indeed the Peugeot EX1 Concept car has already broken the following international records (approved by the International Automobile Federation) for an electric-powered terrestrial vehicle.

This series of records was established, by Nicolas Vanier, the famous French explorer and film-maker ("The Last Trapper", "Wolf") who drove the Peugeot EX1 Concept car.

Between now and the end of the year, China, the world's largest car market, will be the setting for the Peugeot EX1 Concept to pursues other world records.
