1986 Peugeot Proxima

The Proxima concept was presented in 1986 at Paris Motor Show, representing the highest expression of Peugeot technology, that enabled the french manufacturer to win two World Rally Championship titles (in 1985 and 1986) with the 205 Turbo 16 model.

All the car mechanics is features an extensive use of electronic controls: from engine control to transmission, traction and braking system.

The exterior body is made with composites panels (carbon fibers), and the cockpit is defined by a large transparent surface, made in polycarbonate.

The design features very small overhangs (the rear one is practically eliminated), with the wheels located at the four corners of the car virtual perimeter, putting the accent on power and performances.

Technology
Peugeot Proxima's engine is a V6 2.8 liters equipped with two turbocompressors and two air-liquid intercoolers that enable to reach a max power of 442 kW (600 HP) and 608 Nm of max torque.

It makes use of ceramic-coated mechanical components to reduce power losses due to friction. The engine is electronically controlled and features a multi-point sequential injection.

Electronic device are also present in the gearbox, with automatic actuators for the levers and the clutch disk.

Proxima is a non-permanent 4 wheels drive vehicle: if a risk of skidding is detected, the power is transferred to the front axle by the closing of a second multi-disk clutch, moved by an electronic module.

The braking systems features ventilated carbon discs and ABS, and the suspensions are made up of front and rear dual A-arms, derived from the successful simulation analysis used to create the 205 GTI and 205 Turbo 16 models.

Interiors
Únder the large polycarbonate roof, split into two halves, Proxima reveals a strong-coloured cockpit, capable of transporting 4 passengers (2+2 configuration), who enter the vehicle by opening the roof halves (the rear half can slide back to the rear end) and stepping over the vehicle sides, since no traditional doors are available.

The four seats are positioned inside a surrounding volume made of a unique element. Traditional materials, such as the handcrafted leather, live together with innovative solutions, like the satellite navigation system (in 1986!) and a visualization device made of 5 external cameras and a software capable of integrating the different views into a unique image of the environment surrounding the vehicle.

This kind of system is still under research and is featured, for example, on modern concept cars like Nissan Pivo.

Among the additional features are the electronic key-card and the interior ventilation system, powered by solar energy thanks to photovoltaic cells located above the rear engine cover panel.
