A compliment to the earlier Road Test book and does not repeat any of the articles. The DS was a completely new concept in car design and construction. A high-pressure hydraulic system lay at its heart and was radically different from anything else on sale. The simpler ID was introduced to lure customers away from more conventional cars. At the end of production the styling was still fresh and unusual, and the suspension, a revelation to drivers, is probably only bettered by the modern Citroens. This is a book of contemporary road and comparison tests, specification and technical data, model introductions, long term reports; rebuild advice and a historical overview. Models covered include: DS19, ID19, ID Safari, Wagon, Connaught GT, DW, DS21, Pallas, Safari Confort 21, 3DS, DS20, DS21 Pallas Efi 139.
