The body shell is of one-piece design and safety cell construction, whereby the outer members yield progressively and in a controlled direction in the event of impact, giving maximum protection to the passenger compartment. The body panels are of lightweight high strength steel.

The front wings are bolted to the main body for ease of removal. The complete body is given an extensive anti-corrosion treatment during manufacture; including stone chip protection and wax injection. Peugeot guarantee the body against perforation as a result of corrosion for a period of six years provided the car is given periodic inspections by a Peugeot garage.
