What is it?
This is the Peugeot 208 Hybrid FE concept, which made its public debut at the Frankfurt show in September.
Based on the standard-issue supermini, the FE (‘Fun’ and ‘Economy’) is a showcase for a range of new technologies and new ideas that have created a car with emissions officially rated at just 46g/km on the NEDC driving cycle; it's also capable of reaching 62mph in eight seconds from a standing start.
Peugeot engineers (of whom around ten were drafted in from Peugeot Sport) and Total worked together on the concept, which has been taken from a clean sheet of paper to two running mules in just 16 months.
Engineers say that the major engineering work on the standard 208 centred on four areas: improving aerodynamics, reducing overall weight, improving the economy of the petrol engine and adding an electric hybrid system.
‘Improving aerodynamics’ has meant a significant – and very clever – change to the rear of the 208. The FE gets a new tail section, which slots onto the rear of the body, in place of the factory tailgate and bumper. The underneath of the FE is also completely flat and the radiator grille is 40 per cent smaller. The width of the rear end of the car has also been narrowed by 40mm. The upshot is a Cd of 0.25, a 25 per cent reduction in drag.
Peugeot also worked with Total’s polymers division and subsidiaries CCP Composites and Hutchinson to develop lightweight composite panels for the 208 factory bodyshell, replacing the skin panels and the floor pressings.
The 20kg outer skin is made in one piece; the bonnet weights 5kg and the wings 2.1kg. The interior mouldings have been made from a mix of polypropylene and natural fibres, saving a remarkable 15kg. The body’s weight is reduced from 295kg to 227kg. Polycarbonate windows (doors aside) save another 5kg.
Peugeot and Hutchison have also completely re-thought the suspension system, replacing the McPherson struts and rear beam axle with two large transverse leaf springs.
