Model Development
The Dyna X was replaced by the more streamlined Dyna Z in 1954. This was later developed into the similar PL 17, launched in 1959, in an attempt to conform to the styles of the time.
The Dyna Z's body was originally aluminium, like that of the preceding Dyna X, with steel tube subframes front and rear, joined by steel plate reinforcements in the sills. The aluminium was gradually replaced by steel during 1956 as the cost differential between the two materials became unsupportable. The suspension was modified and the shock absorbers changed to cope with the extra weight. By 1958, only the bumpers, the fuel tank, the engine cooling shroud and most of the engine and transaxle cases were aluminium, but the weight was still quite low for a relatively comfortable six-seater saloon, when compared with narrower competitor models from Peugeot and Simca. Its unusual and very modern design gave it a unique combination of space, ride comfort, performance and fuel economy at a very competitive price. But reliability suffered and fuel prices were not high enough, even in France, for people to put energy efficiency first. The car also suffered from some engine and wind noise. The Tiger version had a racing inspired engine and a full cooling shroud.

Famous quotes containing the words model and/or development:
“It has to be acknowledged that in capitalist society, with its herds of hippies, originality has become a sort of fringe benefit, a mere convention, accepted obsolescence, the Beatnik model being turned in for the Hippie model, as though strangely obedient to capitalist laws of marketing.”
—Mary McCarthy (1912–1989)
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
